【摘要】：以钨铁和炭黑为原料采用真空烧结反应合成制备了WC铁基耐磨材料,通过XRD、OM、SEM、EDS、硬度计与湿沙橡胶轮式磨损试验机等研究其组织与性能。结果表明:在1250~1450℃的温度区间内进行烧结,均可原位合成WC,同时生成少量Fe_3W_3C相;原位合成的WC颗粒细小,且弥散分布于基体,而Fe_3W_3C相随温度的升高而长大;当烧结温度为1350℃时,材料的力学性能最佳,宏观硬度高达56 HRC,磨损质量损失最小,其相对耐磨性为Q235钢的27倍。
[Abstract]:WC iron based wear resistant material was synthesized by vacuum sintering reaction with tungsten iron and carbon black. The microstructure and properties of WC iron base wear resistant material were studied by means of XRDX OMU SEMN EDS, hardness tester and wet sand rubber wheel wear tester. The results showed that the sintering was carried out in the temperature range of 1250 ~ 1450 鈩，
