[1]Properties, functions, categories and advantages of wear-resistant coatings

       

The operation of equipment will inevitably have friction, and friction will inevitably be accompanied by wear. Therefore, it is very common for metal friction and wear to appear on equipment, and wear-resistant coatings can provide the surface of mechanical equipment parts with wear resistance, corrosion resistance, High temperature resistance, insulation, high pressure resistance, and oxidation resistance. To improve the service life of metal parts, today we will talk about the performance, function, category and advantages of wear-resistant coatings.

Performance characteristics of wear-resistant coating:

1. Good appearance and color, and can process products of various shapes;

2. It has excellent corrosion resistance and chemical stability;

3. Excellent metal surface adhesion and rust resistance, which can prevent abrasion, abrasion and sintering between metals;

4. Excellent water erosion resistance and corrosion resistance, low friction coefficient, and wide operating temperature range;

5. It has the characteristics of anti-friction, prevention of stickiness, high temperature resistance (400℃), etc., suitable for use in high temperature and high pressure environments.

The role of wear-resistant coating:

1. It can prevent the firmware from sticking and biting

Metal equipment coated with wear-resistant coating on the surface is not prone to rust, seizure, and seizure after use.

2. Anti-rust and anti-corrosion

The wear-resistant coating will form a dense and firm lubricating film on the surface of the workpiece, which cuts off the contact between the metal substrate and the air, making it difficult to rust.

3. Wear resistance

Based on the excellent wear resistance and self-lubricity of the wear-resistant coating, metal parts can be loosened and locked repeatedly without damage to the surface of the part.

4. Lubrication problems are not limited in high temperature and low temperature environments

Metal equipment parts with wear-resistant coatings will not be embrittled due to too low or too high temperature, and still have lubricating properties.
