METAL POWDER FOR MANUFACTURING CEMENTED CARBIDE SPACER COMPRISING TUNGSTEN CARBIDE AND NICKEL-BASED METAL CONTAINING AND METHOD FOR MANUFACTURING CEMENTED CARBIDE SPACER

摘要

The present invention relates to metal powder for manufacturing a cemented carbide spacer that includes metal powder containing tungsten carbide powder and nickel-based metal powder and is manufactured using plasma transferred arc (PTA) overlay welding. The present invention provides metal powder for manufacturing a cemented carbide spacer, which comprises 50-65 parts by weight of tungsten carbide powder, 5-10 parts by weight of cobalt powder, and 25-40 parts by weight of nickel-based self-fluxing powder. The cemented carbide spacer according to the present invention has excellent wear resistance while being manufactured through a simple process.;COPYRIGHT KIPO 2020
