Characteristics and Applications of Laser Cladding Processing for Glass Molds

Laser cladding processing of glass molds is a new processing technology. Its principle involves irradiating the surface of the glass mold with a high-energy laser beam to rapidly melt the surface, forming a high-hardness layer. This coating enhances its wear resistance, corrosion resistance, and high-temperature resistance.

I. Principle of Laser Cladding Processing for Glass Molds

The principle of laser cladding processing for glass molds involves using a high-energy laser beam to irradiate the surface of the glass mold, causing rapid melting and the formation of a high-hardness coating. This improves its wear resistance, corrosion resistance, and high-temperature performance. During the laser cladding process, the high-energy laser beam is focused on the surface of the glass mold, rapidly melting the surface material to form a molten pool. Simultaneously, high-hardness coating materials such as carbides and nitrides are added to enhance the hardness and wear resistance of the coating. Under the action of the laser beam, the coating material in the molten pool rapidly cools and crystallizes, forming a high-hardness coating.
