磨损在机器中到处可见,尤其是农林机具,成天在泥土、砂石中工作,零件磨损更甚。许多刀具既要求质硬耐磨又希望刀刃锋利不怕冲击,故一般材料实难刚柔兼备,满足需要。最近浙江大学材料系金属材料教研组已研制出一种抗磨粒磨损新材料——65MnMoTi4钢,堪称耐磨材料的佼佼者。浙江省林科所用它制作便携式挖根 Wear can be seen everywhere in the machine, especially in agriculture and forestry equipment, all day work in the soil, gravel, parts wear even worse. Many tools require both hard and wear hard and hope that the blade is not afraid of the impact of sharp impact, so the material is generally hard to both rigid and flexible to meet the needs. Recently Zhejiang University Materials Department of Metal Materials Teaching and Research Group has developed a new anti-wear abrasive material - 65MnMoTi4 steel, called the leader in wear-resistant materials. Zhejiang Forestry Branch used it to make portable root digging
