Laser cladding of glass molds is a new processing technology. Its principle is to irradiate the surface of glass molds with a high-energy laser beam to melt the surface quickly and form a high-hardness layer. The coating can improve wear resistance, corrosion resistance and high temperature resistance.
1. The principle of laser cladding processing of glass moulds
The principle of laser cladding processing is to use a high-energy laser beam to irradiate the surface of the glass moulds to melt the surface quickly and form a high-hardness coating to improve its wear resistance, corrosion resistance and high-temperature resistance. In the process of laser cladding, the high-energy laser beam is focused on the surface of the glass molds to melt the surface material quickly and form a liquid pool. At the same time, high-hardness coating materials such as carbide and nitride are added to enhance the hardness and wear resistance of the coating. Under the action of the laser beam, the coating material in the liquid pool quickly cools and crystallizes, forming a high-hardness coating.
