【摘要】 采用氧 -乙炔焰一步喷熔法 ,将混合均匀的碳化物与 1号合金粉 ,喷覆在烧结机布料器的工作面上 ,取代原0 Cr18Ni9不锈钢工作层 ;然后将含钨的耐磨合金堆焊在喷焊层上 ,并改进工作面结构。采用表面强化技术后 ,布料器使用寿命提高 5倍以上更多还原

【Abstract】 The even mixture of carbide and No.1 alloy powder is jetted on working surface of distributor of sintering machine used of one Spray melting method with oxgyen ethyrce flame to replace old working layer of 0Cr18Ni9Ti stainless steel,antifrication tungsten alloy is welded on spray welding layer used build up welding,thus the micro structure of working surface is improved.Because strengthening surface technique is used,the service life of this distributor is increased by a factor of 6 above.更多还原
