摘要

为了利用激光沉积技术制备高强度耐磨部件,提高轨道交通设备部件的使用寿命。激光沉积技术用于在 AISI 1045 钢基材表面制造镍钛铁涂层。通过改变激光功率来调节激光能量密度,制备出不同能量密度的铁镍钛复合涂层。对复合涂层的形貌、微观结构、相组成、拉伸强度、显微硬度和摩擦磨损特性进行了观察和测试。研究了激光能量密度对复合涂层组织变化和摩擦磨损性能的影响模式和机制。当激光能量密度为 97.2 J/mm2 (1400 W) 时,沉积层中的残余应力最小,因此裂纹和气孔缺陷较少,气孔率达到最低值 1.2%,密度为 99.1%。随着能量密度的增加,沉积层的拉伸强度和伸长率都呈现出先增加后减小的趋势。通过调节激光能量密度,可以有效控制铁-镍-钛沉积层的硬度和耐磨性。

Frontiers | Impact of laser energy density on the structure and properties of laser-deposited Fe‒Ni‒Ti composite coatings
To utilise laser deposition for the preparation of high-strength, wear-resistant components, the service life of components in rail transportation equipment should be improved. Laser deposition technology is used to fabricate Fe‒Ni‒Ti coatings on the surface of AISI 1045 steel substrates. By varying the laser power to adjust the laser energy density, Fe‒Ni‒Ti composite coatings are prepared at various energy densities. The morphology, microstructure, phase composition, tensile strength, microhardness, and friction-wear characteristics of the composite coatings are observed and tested. The influence patterns and mechanisms of laser energy density on the organisational variation and friction-wear performance of composite coatings is investigated. When the laser energy density is 97.2 J/mm2 (1400 W), the residual stresses in the deposition layer are minimised, resulting in fewer cracks and gas pore defects, with a porosity rate reaching its lowest value of 1.2% and a density of 99.1%. With the increase in energy density, both the tensile strength and elongation of the deposited layer exhibited an initial increase followed by a decrease. The hardness and wear resistance of Fe‒Ni‒Ti deposition layers is effectively controlled by regulating the laser energy density.
