Metal surface treatment of metal refers to the process of performing specific physical, chemical, or mechanical treatments on the surface of metal materials. This is done with the intention of improving various aspects such as corrosion resistance, mechanical properties, appearance quality, or other specific performance requirements of metals. Metal surface treatment is a process of artificially forming a surface layer on the surface of the base material that is different from the mechanical, physical, and chemical properties of the base. The purpose of metal surface treatment is to meet the product's corrosion resistance, wear resistance, decoration, or other special functional requirements. For metal castings, our more commonly used surface treatment methods are mechanical polishing, chemical treatment, surface heat treatment, spraying surface, etc.
The functions of metal surface treatment can be summarized as follows:
● Improve the appearance
● Add specific beautiful colors
● Change the luster
● Enhance chemical resistance
● Increase wear resistance
● Limit effects of corrosion
● Reduce friction
● Remove surface defects
● Cleaning the parts
● Serve as a primer coat
● Adjust the sizes
Importance of Metal Surface Treatment
Metal surface treatment is an additional process applied to the surface of a material for the purpose of adding functions such as rust and wear resistance or improving the decorative properties to enhance its appearance.
Painting, such as that applied to the body of an automobile, printing of the manufacturer's name and other information on the surface of home appliances, and "plating" applied under the paint on guardrails, are typical examples of metal surface treatment.
Heat treatment, such as quenching, applied to metal parts such as gears and blades, is also classified as metal surface treatment.
Metal surface treatments can be broadly classified into removal processes, such as scraping or melting the surface, and additive processes, such as painting, which add something else to the surface.
Types of Metal Surface Treatments
According to different processes, we can simply classify metal surface treatment as: Surface modification, surface alloying, surface conversion coating, surface patterning.
Surface modification
By changing the properties of the material surface, such as hardness, wear resistance, corrosion resistance, etc., the overall performance of the material is improved without changing the chemical composition.
The polishing, drawing, and rolling we often use are surface modification technologies.
Surface alloying
Form an alloy layer on the metal surface to improve metal surface treatment such as hardness, wear resistance, corrosion resistanc and more.
Such as nitriding and hot dip plating.
Surface conversion coating
Through chemical methods, the added materials react chemically with the matrix to form a conversion film.
Typical methods are anodizing, blackening and phosphating.
Surface patterning
Through physical and chemical methods, the added material forms a plating or coating on the surface of the substrate. Note that the substrate does not participate in the formation of the coating.
It includes electroplating, electroless plating, silk screen printing, laser etching and other methods.
Different metal surface treatment methods have different steps and vary according to customer and product requirements. Generally, it includes:
Inspection and preparation: Inspect the rough-finished product to ensure there are no obvious defects, contamination or damage. Prepare equipment, materials and more for finishing.
Pretreatment: Take appropriate measures for cleaning as needed, such as removing grease, dirt or other impurities.
Surface treatment: Choose an appropriate method to surface treat the product.
Drying and curing: If the coating or plating needs to be dried or cured, the metal parts need to be placed at the appropriate temperature to ensure that the coating or plating achieves the required performance.
Inspection: After metal surface treatment, quality control and testing are performed to ensure that the treated metal surface meets specifications and requirements. Including appearance inspection, coating thickness measurement, corrosion resistance testing and more.
Why Metal Surface Treatment Is Important?
Do metal products usually require surface treatment? Do you know what it does?
Anti-corrosion
Metals such as steel and iron-aluminum alloys are often treated for anti-corrosion through galvanizing, coating, oxidation and other methods to improve their resistance to oxidation and corrosion and extend their service life. It is widely used in the fields of building structures, automobiles, ships and pipelines.
Rust treatment
Prevent metal from rusting due to oxidation. Anti-rust methods include the use of antioxidants, coatings, alloy designs and other technologies.
Improve hardness and strength
The hardness and strength of metal can be improved through heat treatment, nitriding, carbonization and other methods. It is of great significance for manufacturing high-strength parts, tools and mechanical components.
Improve electrical conductivity
Metal surface treatments can be used to improve electrical conductivity. It plays an important role in some applications that require excellent conductive properties, such as electronic devices, cables and connectors.
Beautiful decoration
Metal surface treatment can be used to improve the appearance of metal products, such as spraying, polishing, plating. This is common in home furnishing, architectural decoration, jewelry and other fields.
Improve wear resistance
The wear resistance of metal materials can be improved through surface coating, spraying or other treatment methods. Suitable for applications requiring anti-wear properties, such as automotive parts, construction machinery and more.
Reduce friction coefficient
Metal surface treatment helps reduce the friction coefficient between metal materials and improve the movement efficiency of mechanical parts. This is of great significance for automotive engine parts, bearings.
Improve heat resistance
Some metal surface treatment methods, such as high-temperature coating and heat treatment, can make metal materials have better high-temperature resistance. Suitable for high temperature working environment.
How to Choose the Right Metal Surface Treatment Method?
The choice depends on the application, required properties, cost, and environmental considerations.
Application
The metal surface treatment plays a significant role in the decision-making process. Different treatments may be more suitable for specific uses, such as corrosion resistance in automotive or aerospace industries.
Required properties
The required properties of the metal surface treatment, such as hardness, durability, and conductivity, also dictate the choice of treatment method.
Cost
Cost is another important consideration, as some treatments may be more expensive than others.
Environmental considerations
Environmental factors, including the impact of chemicals and waste generation, should also be considered to ensure a sustainable and eco-friendly process.
The Role of Power Supplies in Metal Surface Treatment
Today, metal surface treatment technologies are used in a variety of industries. Electrolytic plating, in particular, will continue to expand its applications and will require high-quality, economical technology.
Electrolytic plating uses electrolysis, which requires a power source that can deliver direct current (dc) power supply. If the voltage is unstable, the deposition of the plating will also be unstable, so voltage stability is required to improve the quality of the product. The amount of plating deposited is proportional to the accumulated current, so it is important to be able to flow more current efficiently.
Furthermore, since chemicals are used for plating, the environment is prone to rust and corrosion due to corrosive gases and high humidity. Therefore, not only does the power supply enclosure need to be environmentally resistant, but it is also necessary to install the power supply in a different location from the room where the plating will take place.
A metal coating is an organic or inorganic layer that is applied to a surface (substrate) for a variety of reasons. The purpose of the metal coating may be decorative, such as paint, or it may be to protect the surface of the substrate from the environment (improve corrosion resistance), such as galvanizing. Metal coatings can also improve wear resistance in mechanical application, or act as a thermal barrier. Depending on the material and applications, metal coatings may be one or more layers.
Metal surface treatment is a process by which the outermost layer of the material is metallurgically modified, as opposed to metal coatings, which are applied over a substrate with no effect on the properties of the base material. The most common application of metal surface treatment is case hardening. The hardness at the surface of the material is increased substantially through various types of thermal treatments, such as carburizing. A common application for case hardening is on bolts and screws. This treatment may also be combined with a metal coating or plating process, such as galvanized case hardened bolts.
