斗齿、齿座是装载机、挖掘机主要的磨耗件之一。目前在我国大规模的基本建设中，挖掘机、装载机的使用量不断增加，斗齿、齿座在作业过程中直接与砂、土、岩石、矿物等接触，受到严重的磨料磨损，消耗量很大，开发斗齿、齿座新材料，减少磨损而造成的损失，具有重要的经济意义 Bucket teeth, tooth seat is loader, excavator one of the main wear parts. At present, in large-scale capital construction in our country, the usage of excavators and loaders is increasing. The bucket teeth and the tooth bases are in direct contact with sand, soil, rock, minerals and the like during the operations and are subjected to serious abrasion and wear and tear It is of great economic importance to develop new materials for the teeth and toothed joints to reduce the loss caused by wear and tear
