【摘要】 对粉末烧结制备的WC-Fe/Ni/Co硬质合金覆层材料,在MPX-2000型盘销式摩擦磨损试验机上进行了无润滑的摩擦磨损试验。结果表明,WC-Fe/Ni/Co硬质合金覆层材料组织致密、细小、硬质相分布均匀,界面结合良好,具有较高的硬度和耐磨性。磨损的产生是硬质相的剥落引起的。更多还原

【Abstract】 The cemented carbide cladding of WC-Fe/Ni/Co prepared　by powder sintering were studied using disc-pin friction and wear tester.The results show that the cemented carbide cladding of WC-Fe/Ni/Co has compact structure and fine grains;distribution of its hardness phases is uniformity and the combination of cladding and substrates strong,the cladding has good hardness and wear resistance. The abrasion of cladding resulted in the desquamation of hardness phases.更多还原
