摘要
成功研制了一种适用于抗冲击磨料磨损条件下的堆焊合金,合金系统为Fe-Mn-Cr-Mo-V,在受到较大载荷冲击后较焊态堆焊层硬度提高66%。因此该堆焊合金的抗冲击磨料磨损性能和堆焊层金属的加工硬化效果都很优异。在保证堆焊层组织为奥氏体的前提下,系统地研究了合金元素Cr、Mo、V等多元复合强化提高抗磨料磨损的能力及其对堆焊层组织性能的影响规律。
A kind of hardfacing alloys were developed for impact wear-resistant which is a Fe-Mn-Cr-Mo-V alloy system. After impact experiment the hardness degree of deposited metal increases 66 % compare with the hardness degree of deposited metal as welded. So the hardfacing alloys not only has good performance of impact wear-resistant, but also has super work-hardening effect.The effect of alloy elements such as Cr, Mo, V on the deposited metal and improves the ability of wear-resistant was studied.
