Tungsten Carbide Spray Reinforced Function Roller Anti-corrosion and wear resistance

The reasons for the supersonic spraying of tungsten carbide in curved rollers include:

1、Improve bonding strength: The high temperature and high-speed flame flow generated by supersonic spraying can make tungsten carbide powder particles obtain a higher speed, and form a coating with high bonding strength when hitting the matrix.

2、Control coating quality: The high flame speed but relatively low temperature of supersonic spraying helps to reduce the decomposition of tungsten carbide during the spraying process, resulting in a dense coating with good wear resistance.

3、Enhanced wear resistance: Tungsten carbide coating hardness is very high, close to diamond, can significantly improve the wear resistance of curved rollers, extend the service life.

4、Suitable for complex shapes: Supersonic spraying is suitable for complex shape roller surface treatment, which can form a uniform coating on non-flat surfaces such as curved rolls.

5、Improved chemical stability: Tungsten carbide has good chemical stability and can improve the corrosion resistance of curved rolls.

6、Improve production efficiency: Supersonic spraying can complete the preparation of the coating in a short time and improve production efficiency.

7、These advantages make the supersonic spraying of tungsten carbide an effective method to improve the wear resistance of curved rolls.
