采用复合技术对工业41Cr4（ISO标准）钢进行了表面处理。首次采用传统的渗碳、渗氮工艺在41Cr4钢表面引入中间层。然后在中间层上刷镀硬铬涂层。最后，通过强流脉冲电子束（HCPEB）对涂层进行改性，然后进行淬火和随后的回火处理。并对其显微组织、力学性能和断裂行为进行了表征。结果表明，采用该复合工艺可在41Cr4钢表面形成纳米晶Cr涂层。纳米晶Cr涂层具有良好的硬度和耐腐蚀性能，满足了齿轮在高速和腐蚀环境下工作的要求。本研究所提出的复合工艺，由于齿轮表面的多功能层设计，被认为是一种新的前景方法。
Commercial 41Cr4 (ISO standard) steel was treated by a composite technique. An intermediate layer was introduced firstly at the 41Cr4 steel surface by traditional carburizing and nitriding. Then a hard Cr coating was brush-plated on the intermediate layer. Finally, the coating layer was modified by high current pulsed electron beam (HCPEB), followed by quenching and subsequent tempering treatment. The microstructure, mechanical properties, and fracture behavior were characterized. The results show that a nanocrystalline Cr coating is formed at the 41Cr4 steel surface by the treatment of the new composite technique. Such nanocrystalline Cr coating has acceptable hardness and high corrosion resistance performance, which satisfies the demands of the gears working under high speed and corrosive environment. The composite process proposed in this study is considered as a new prospect method due to the multifunction layer design on the gear surface.
