摘要
研究了一种新型高强度CoCrCu合金材料,重点测试了抗磨损性能。试验在无润滑干摩擦条件下进行,以砂轮片为对偶件,并以相同条件下CrCu和45#钢材料的磨损性能为对比。通过扫描电镜观察磨损形貌,CoCrCu合金材料的磨损表面平整光洁,犁沟现象轻微,未发现氧化、粘着磨损和磨屑颗粒镶嵌在试样表面深处现象,表现为滑动磨损形态,并具备低且稳定的摩擦系数(μ≤0.19),磨损失重较小。试验结果表明,该材料具有优良的抗磨损能力。
A new kind of high-strength CoCrCu alloy material was studied, of which wear resistance properties was mainly tested. The experiments conditions were non-lubricated dry friction with grinding wheel piece as the counterpart and the wear properties of CrCu and 45° steel under the same conditions for comparison. By the SEM observation of morphology, the worn surface of CoCrCu was smooth with slight furrow phenomenon. At the same time, oxidation, adhesive wear and the phenomenon of wear debris particles embedded in the depths of the specimen surface was not found. The friction morphology manifested as sliding friction and wear patterns with low and stable coefficient of friction （μ〈0.19） , and wear mass loss of alloy is less. The experiments show that the material has excellent wear resistance.
