摘　　要：首先采用不同技术在30CrMnSiA钢表面制备了6种黑色多功能改性层,分别是采用电镀技术制备了纯Cr镀层、纯Ni镀层、纯Zn镀层和Zn-Ni复合镀层,采用低温渗氮+氧化(LTN+O)复合技术制备了LTN+O复合层,以及采用物理气相沉积(PVD)技术制备了PVD涂层,随后利用X射线衍射仪、扫描电镜等对黑色多功能改性层的组织结构进行表征,以及通过显微硬度仪、球-盘摩擦磨损试验机和电化学工作站对其力学性能和耐蚀性能进行测试。结果表明:采用电镀、低温渗氮+氧化复合以及PVD沉积等技术均可在30CrMnSiA钢表面成功制备黑色多功能改性层;在硬度方面,PVD涂层硬度最高,达到1610 HV0.05;在摩擦磨损性能方面,相比30CrMnSiA钢基体,黑色多功能改性层的摩擦系数均略有升高,除纯Ni镀层外,其他改性层的耐磨性能均优于30CrMnSiA钢基体;在结合力方面,PVD涂层和纯Ni镀层的结合力最好,压痕边缘位置无裂纹;在耐蚀性方面,相比30CrMnSiA钢基体,Zn-Ni复合镀层和LTN+O复合层耐蚀性有所提高,其他改性层的耐蚀性有所降低。Firstly,six black multifunctional modified coatings were prepared on the surface of 30CrMnSiA steel using different techniques,which were:pure Cr coating,pure Ni coating,pure Zn coating and Zn-Ni composite coating were prepared using electroplating technology,LTN+O composite coating was prepared using low-temperature nitriding+oxidation(LTN+O) composite technology,and PVD coating was prepared using physical vapor deposition(PVD) technology.Subsequently,microstructure of the black multifunctional modified coatings was characterized by X-ray diffraction and scanning electron microscopy,and their mechanical properties and corrosion resistance were tested using a microhardness tester,a ball disc friction and wear tester and an electrochemical workstation.The results show that the black multifunctional modified coatings can be successfully prepared on the surface of the 30CrMnSiA steel using electroplating,low-temperature nitriding+oxidation composite and PVD deposition techniques.In terms of hardness,the PVD coating has the highest hardness,reaching 1610 HV0.05.In terms of friction and wear performance,compared to the 30CrMnSiA steel substrate,the friction coefficient of the black multifunctional modified coatings has slightly increased,except for the pure Ni coating,the wear resistance of other modified coatings is better than that of the 30CrMnSiA steel substrate.In terms of adhesion,the PVD coating and pure Ni coating have the best adhesion,and there are no cracks at the edge of the indentation.In terms of corrosion resistance,compared to the 30CrMnSiA steel substrate,the corrosion resistance of the Zn-Ni composite coating and LTN+O composite coating has been enhanced,while the other modified coatings have decreased.
