This work aims to characterize and compare the coefficient of friction (CoF) and wear rates of some metallic materials (AISI 6061-T6 alloy, AISI 316 L stainless steel and ASTM F1537 CoCrMo alloy) under different wear modes, namely, micro-abrasion abrasion (rolling and mixed rolling/grooving abrasion), and wet and dry sliding abrasion. The wear modes were achieved by conducting testing under muddy environment at different SiC abrasive particles concentration and wet and dry conditions at three different loads (1, 2 and 3 N) using an instrumented micro-abrasion tester. Wear volumes were measured by optical profilometry to estimate wear rates, while wear patterns were visualized in detail by SEM. CoF, wear rate and mode results for all materials and conditions are reported and discussed. Wear modes were found to have a considerable effect on CoF and wear rate for the materials. Pure rolling abrasion generated the highest wear rates for all materials. Mixed rolling abrasion/grooving produced higher CoFs, but lower wear rates than those produced by pure rolling abrasion. Wet sliding promoted the highest CoFs for AISI 316L SS and AISI 6061-T6 meanwhile dry sliding generated the lowest CoFs and wear rates.

金属在微磨损,湿和干滑动条件下的摩擦磨损

这项工作旨在表征和比较某些金属材料(AISI 6061-T6合金,AISI 316 L不锈钢和ASTM F1537 CoCrMo合金)在不同磨损模式下的摩擦系数(CoF)和磨损率,即微磨损(轧制和混合轧制/开槽磨损)以及干湿滑动磨损。磨损模式是通过使用仪器化微磨耗仪在泥泞的环境下,在三种不同负载(1、2和3 N)下,在不同SiC磨料浓度和湿,干条件下进行测试来实现的。通过光学轮廓仪测量磨损量以估计磨损率,同时通过SEM详细显示磨损模式。报告并讨论了所有材料和条件的CoF,磨损率和模态结果。发现磨损模式对材料的CoF和磨损率有很大影响。纯滚动磨损产生了所有材料的最高磨损率。混合滚磨/开槽产生的CoF较高,但磨损率低于纯滚磨产生的CoF。湿滑促进了AISI 316L SS和AISI 6061-T6的最高CoF,而干滑则产生了最低的CoF和磨损率。
