随着我国大型水利工程的兴建和高等级公路的迅猛发展，挖掘机的使用量不断增加，斗齿的消耗量更加巨大，所以开发斗齿用新型抗磨材料，减少斗齿磨损造成的损失，已日益引起重视。我们在研究国内外传统斗齿材料的基础上，开发了一种新型耐磨耐冲击用斗齿材料。l斗齿材料的化学成
With the construction of large-scale water conservancy projects in our country and the rapid development of high-grade highways, the use of excavators is increasing and the consumption of bucket teeth is even greater. Therefore, the development of new anti-wear materials for bucket teeth reduces the loss caused by tooth wear, It has drawn increasing attention. We have developed a new type of wear-resistant and impact-resistant tooth material based on the study of traditional tooth materials at home and abroad. l tooth material chemical into
