In the mechanical, steel, aluminum, and metalworking industries, surface quality is always a determinant of the longevity, corrosion resistance as well as aesthetics of the product. Therefore, metal surface treatment is increasingly becoming an indispensable important stage in the modern production chain involving CHEMICALS.
Not only do they help increase durability, rust resistance and improve paint adhesion, but advanced surface treatment technologies involving CHEMICALS also play a key role in green manufacturing trends and raise global industrial quality standards.
Popular metal surface treatment methods today
Before plating or coating, the metal surface needs to be thoroughly treated to remove grease, impurities, rust and create an optimal adhesion base for the coating.
The selection of appropriate chemicals is crucial for achieving optimal results in metal surface treatment.
Mechanical Grinding – A traditional but effective cleaning step
This is a method of using abrasive materials to conduct rough grinding and fine grinding of metal surfaces. This process eliminates triple via, flattens the surface, and adds gloss to the product before plating or painting.
Mechanical grinding is still widely used in the mechanical engineering industry, stainless steel processing, steel and industrial components.
Ball Rotation – The Ultimate Solution for Small Parts
For parts with small sizes or complex shapes that are difficult to handle with conventional grinding methods, dry ball turning or wet ball turning technique is considered the right choice.
This method helps the metal surface achieve high uniformity, increase aesthetics and improve stain resistance.
Chemical Treatment – The “Heart” of Surface Treatment Technology
This is the most important method in modern surface treatment processes. Through chemical or electrochemical reactions, the grease, oxide and rust layer on the metal surface will be completely removed before plating or coating.
Common techniques include:
- Degreasing with organic solvents
- Degrease with an alkaline solution
- Electrochemical Oil Removal
- Acid rust removal
- Phosphating
- Passivation of metal surfaces
As a result, the product has higher corrosion resistance, a more durable coating, and an increased service life in harsh industrial environments.
Chemicals that play an important role in metal surface treatment
Along with the treatment technology is a specialized chemical system – a factor that directly determines the operational efficiency and quality of the finished product.
Alkaline Degreasing Chemicals
This is a line of chemicals commonly used to remove grease and dirt from the surface of steel, iron, aluminum, copper or zinc.
Depending on the type of metal and the level of contamination, you can choose a strong, medium, or light alkaline solution to ensure optimal cleaning efficiency without affecting the metal substrate.
Acid Degreasing Chemicals
Acid degreasing solutions are commonly used for galvanized steel and surfaces that require high cleanability but still ensure that they do not damage the plating.
This chemical is particularly effective in treating industrial oils that have been on metal surfaces for a long time.
Aluminum Removal Chemicals
In the aluminum and aluminum alloy industry, aluminum cleaning chemicals help clean, regenerate surfaces and increase adhesion to plating or backcoating.
Zinc Phosphate – An Effective Anti-Corrosion Solution
Zinc phosphate is one of the most popular pretreatment technologies today, especially in the powder coating industry.
The phosphate layer created on the metal surface is capable of:
- Anti-rust
- Increased paint adhesion
- Increased coating strength
- Limit peeling in humid or chemical environments
Chromium Chemistry and Chrome Replacement Technology(VI)
For many years, chromium has been a popular chemical in the plating industry thanks to its superior ability to create an anti-corrosion passivation layer. However, the current global trend is shifting sharply towards chrome(VI)-free solutions to meet stringent environmental standards.
This is also a field that many chemical technology enterprises are focusing on research and development.
