激光涂复层裂纹及其磨损性质的研究

A Study of Fracture and Wear Resistance of Laser Cladding Layer on Graphite Iron Substrate

本文着重对激光涂复层裂纹及其形成机理进行了研究，并分析探讨了涂复层裂纹倾向对其耐磨性的影响关系。为球墨铸铁激光涂复涂层材料的选择以及激光涂复工艺的制定提供实用性经验。

Through a study of the fractures of laser cladding layer and the mechanism of its formation, the authors of this paper have discussed the fracture tendency of the laser cladding layer and its influence on wear resistance, and present some practical principles in the choice of cladding materialls and the performance of laser cladding.
