Description

Technical field [0001] The invention relates to a hard alloy for producing 3D curved glass and a preparation method thereof. Background technique [0002] At present, the technology of manufacturing 3D curved glass is mainly hot bending technology, that is, the glass is bent and shaped by high pressure under high temperature and molten state, and then processed and polished to form 3D glass, which is widely used in 5G mobile phone screens, back covers, and wearable devices , Automotive glass, optical glass and other fields. The glass is at a high temperature during hot bending. At this time, the glass is strongly corrosive. Therefore, the soaking plate material used is required to have corrosion resistance, high temperature resistance, high strength and wear resistance. The materials used in the existing market are mainly tungsten-cobalt cemented carbide and cermet. Cemented carbide materials have good high temperature performance and good electrical conductivity, but their wear...
