To verify the microstructure and properties of laser cladding tungsten carbide nanometer layer
In tungsten carbide, carbon atoms embedded in the gap of the tungsten metal lattice do not destroy the original metal lattice and form interstitial solid solution, so it is also called interstitial compound. Tungsten carbide can be prepared by heating a mixture of tungsten and carbon at high temperatures, and the presence of hydrogen or warp accelerates the reaction. If the oxygen-containing compound of tungsten is used for preparation, the product must eventually be vacuumed at 1500℃ to remove [...]
