【摘要】 探讨了两种不同的环境介质对脉冲放电强化涂层性能的影响。试验表明,在用N2气介质时,强化层的硬度、耐磨性,较在空气中的有明显提高,且涂层中含较多的ε-Fe2-3N相。切割试验表明,在N2气介质下强化的W6Mo5Cr4V2钢带锯条可以获得较高的使用寿命。更多还原

【Abstract】 Effects of surrounding atmospheres on the properties of electrospark alloyed coating was investigated.The results show that hardness and wear resistance of electrospark alloyed coating strengthened in blowing N2 are higher than that in air and the amount of ε-Fe2-3N phase in electrospark alloyed coating strengthened in blowing N2 increases obviously.In addition,cutting test demonstrates that W6Mo5Cr4V2 steel belt saw strengthened in N2 has higher service life than the others.更多还原
