Selman、Darling等人曾提出研制自润滑材料,以降低线绕电位计与磨件之间的摩擦系数,消除滑动表面的“船头”现象,但上述设想尚未见成功的报道。近年来,国内外的研究发现,在Au基合金中加入In元素可减少由于金属转移产生的“船头”现象,但有关合金的相结构、减磨机理均未见报道。本文用透射电镜研究了Au-9Ni-8In合金的显微组织,并探讨了显微组 Selman, Darling and others have proposed the development of self-lubricating materials to reduce the coefficient of friction between the wirewound potentiometer and the wear parts and eliminate the phenomenon of “bow” on the sliding surface. However, the above assumptions have not been reported yet. In recent years, domestic and foreign research found that addition of In element in Au-based alloy can reduce “bow” phenomenon caused by metal transfer, but the phase structure and anti-wear mechanism have not been reported. In this paper, the microstructure of Au-9Ni-8In alloy was studied by TEM, and the microstructure
