硬质合金粉末喷焊是硬化金属零件表面的一种先进工艺。上海阀门一厂经过半年多的摸索,终于试验成功了用氧-乙炔火焰喷焊硬质合金粉末的工艺,并已投入生产。这种喷焊既克服了金属喷涂
Carbide powder spray welding is an advanced technology for hardening the surface of metal parts. Shanghai Valve Factory after more than six months of exploration, and finally successfully tested the oxygen - acetylene flame spray welding carbide powder technology, and has been put into production. This spray welding not only overcome the metal spray
