摘要
采用超音速激光沉积(SLD)和激光熔覆(LC)在316L不锈钢基体上制备了WC/SS316L复合沉积层,对沉积层的宏观形貌、WC分布、显微组织、相成分及磨损性能进行了对比分析。结果表明,LC多道搭接的沉积层中有明显的宏观裂纹,而SLD沉积层表面平整致密,无宏观缺陷。在LC沉积层中,陶瓷相WC呈部分聚集的不均匀分布,而在SLD沉积层中,陶瓷相WC呈弥散状的均匀分布。LC沉积层组织成分分布不均匀,且产生了有害相,而SLD沉积层保持了沉积粉末原有的组织和性能,且表现出形变强化效果。SLD沉积层的摩擦系数比LC沉积层低28%,表现出较优的抗磨损性能。
Abstract
The WC/SS316L composite coatings are successfully deposited on the surface of 316L stainless steel by both the supersonic laser deposition (SLD) and the traditional laser cladding (LC) technologies. The macroscopic morphology, WC distribution, microstructure, phase composition and wear-resistant property of the as-deposited coatings are comparatively studied. The results show that the multi-pass overlapped coating of LC has obvious macroscopic cracks, while the surface of SLD coating keeps smooth and compact without macroscopic defects. In the LC coating, the ceramic WC particles unevenly distribute, while in the SLD coating they uniformly scatter. In the LC coating, the microstructure distribution is non-uniform and is along with the generation of harmful phase, while in the SLD coating, the deposited powder maintains its original microstructure and performance and the severe plastic deformation can also be observed. The friction coefficient of the SLD coating is 28% lower than that of the LC coating, and thus it exhibits a better wear-resistant property.
