采用低温离子硫化工艺及其与离子渗氮、喷丸相结合的双重处理工艺对1045钢进行处理。使用球盘测试仪在发动机油润滑条件下研究了这些处理过的表面的抗划伤、减摩和耐磨性能。使用 SEM、EM XRD 和 AES 检查层的形态和成分以及磨痕。结果表明，硫化双相处理可以明显提高抗划伤性能。氮化+硫化层的承载能力最高，磨损量最低，但加剧了对方的磨损。因此氮化+硫化处理对被处理表面本身更有利。喷丸+硫化层的摩擦系数最低，磨损量也最低。因此喷丸+硫化处理对配合面更加有利。 (C) 2009 Elsevier B.V. 保留所有权利。
Low temperature ion sulphurization process and its duplex treatments combining with ion-nitriding and shot-peening were used to treat 1045 steel. The anti-scuffing, friction-reducing and wear-resistant behaviors of these treated surfaces were investigated using a ball-on-disc tester under engine oil lubrication conditions. SEM, EM XRD, and AES were used to examine the morphologies and compositions of layers, and wear scars. The results show that sulphurization duplex treatments can improve the anti-scuffing behavior obviously. Nitrided + sulphurized layer has the highest load bearing capacity and lowest wear volume, but it intensifies the wear of counterpart. Thus the nitriding + sulphurization treatment is more beneficial to the treated surface itself. Shot-peening + sulphurized layer has the lowest friction coefficient and induces the lowest wear volume of counterpart. Thus the shot-peening+sulphurization treatment is more beneficial to counterpart surface. (C) 2009 Elsevier B.V. All rights reserved.
