一、前言在冶金、采矿、农机具工业中广泛存在的磨料磨损给国民经济带来巨大的损失,为此对磨料磨损机理的研究,新抗磨材料的开发利用也日益深入和丰富。抗磨材料的应用中,在国内比较广泛的应用高锰钢和高铬铸铁。但是,高锰钢在无加工硬化或加工硬化不显著的服役条件下,其优越性并不显著。高铬铸铁具有良好的耐磨性,但高铬铸铁与高锰钢一样,必须在电炉中熔炼。鉴于目前国内中、小工厂仍以冲天炉作为主要的铸铁熔炼手段,废钢供应比较紧张,同时球墨铸铁生
I. INTRODUCTION Abrasive wear, which is widespread in metallurgy, mining and agricultural machinery industry, has brought huge losses to the national economy. Therefore, the study on the mechanism of abrasive wear and the development and utilization of new anti-wear materials have become increasingly in-depth and rich. Anti-wear material applications, the more widely used in the domestic high-manganese steel and high-chromium cast iron. However, high manganese steel without work hardening or work hardening is not significant service conditions, its superiority is not significant. High chromium cast iron has good wear resistance, but high chromium cast iron, like high manganese steel, must be smelted in an electric furnace. In view of the current domestic medium and small factories still cupola as the main cast iron smelting means, tight supply of scrap, while ductile iron Health
