【摘要】：以鎢鐵和炭黑為原料采用真空燒結(jié)反應(yīng)合成制備了WC鐵基耐磨材料,通過(guò)XRD、OM、SEM、EDS、硬度計(jì)與濕沙橡膠輪式磨損試驗(yàn)機(jī)等研究其組織與性能。結(jié)果表明:在1250~1450℃的溫度區(qū)間內(nèi)進(jìn)行燒結(jié),均可原位合成WC,同時(shí)生成少量Fe_3W_3C相;原位合成的WC顆粒細(xì)小,且彌散分布于基體,而Fe_3W_3C相隨溫度的升高而長(zhǎng)大;當(dāng)燒結(jié)溫度為1350℃時(shí),材料的力學(xué)性能最佳,宏觀硬度高達(dá)56 HRC,磨損質(zhì)量損失最小,其相對(duì)耐磨性為Q235鋼的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，
