Tungsten carbide spray coating characteristics
Coating Preparation Features:
1, Flame velocity is very high, usually 5 times the speed of sound.
2, Spray powder speed is very high, up to 2000 m / s.
3, The coating is highly dense, high bonding strength, porosity less than 1%, the bonding strength can be greater than 70Mpa.
4, Low degree of oxidation of coating materials. Loss of carbon is less, high hardness coating.
5, The powder particles in the high-speed flame has been a great kinetic energy, the impact of the substrate and the deposition of particles is significant Guangzhou Si Boryei and deposition of particles in only a small part of the particles exist liquid / solidification and shrinkage process , The vast majority of solid phase deformation, the coating generated in favor of improving the reliability of the coating compressive stress.
6, Some specific materials to meet the occasion of repair.
7, High-speed impact and strong deformation of the lattice distortion of the material, increasing the activity of the material, thereby increasing the adjacent particles or matrix material to generate the possibility of physics, the coating of high reliability.
8, The workpiece is not deformed.
