摘　　要：利用MMW-1立式万能摩擦磨损试验机分别对Ni45涂层试样和Ni45AMo涂层试样进行了干摩擦和油摩擦试验研究。试验结果表明Ni45AMo较Ni45的耐磨性能好。该研究对柴油机排气阀再制造过程中涂层材料的选择具有指导意义。The dry friction and oil friction tests for Ni45 and Ni45AMo coating samples are studied by MMW-1 verti- cal universal friction and wear tester. The test results show that Ni45Amo is better than Ni45 in wear-resistance. This study provides guidance for selection to coating materials during re-manufacturing of diesel exhaust valve.
