犁铧是量大面广的易损基础件,需要量大,消耗钢材多。因此提高犁铧使用寿命,引起各国普遍重视。国外对耐磨合金粉末和堆焊工艺都做了大量的研究工作,并取得了较好的技术经济效果。犁铧堆焊用的耐磨合金种类较多,主要有高铬铸铁(苏联).高钼铸铁(美国)、碳化钨合金(英国、端士、美国、苏联等)以及低合金白口铁等:犁铧的堆焊工艺方法,主要有以下几种:
Plowshare is a large amount of vulnerable basic parts, the amount required, the consumption of steel and more. Therefore, increasing the life of plowshare, causing widespread attention in all countries. Foreign wear-resistant alloy powder and surfacing process have done a lot of research work, and achieved good technical and economic results. Plowshare surfacing with wear-resistant alloys more types, mainly high-chromium cast iron (USSR). High molybdenum cast iron (the United States), tungsten carbide (British, Duan disabilities, the United States, the Soviet Union, etc.) and low-alloy white iron, Plowshare surfacing process, there are the following:
