The joint surface of the glass mold is prone to wear, corrosion, thermal fatigue cracks, oxidation, etc. during use, which can lead to mold failure. Using laser 3D printing technology to prepare advanced high-temperature wear-resistant and corrosion-resistant nickel-based alloy coating on its surface. The coating has excellent wear resistance, corrosion resistance, high-temperature oxidation resistance, and high-temperature thermal fatigue properties, which can greatly increase the service life of the mold.
