煤矿液压支架在服役过程中长期暴露于潮湿、腐蚀的恶劣环境中,表面容易发生腐蚀与磨损。激光熔覆技术提供了一种高效、高质量的表面修复方式,以提高煤矿液压支架的服役寿命。文章综述了液压支架激光熔覆的研究进展,首先介绍了激光熔覆工艺、材料体系对涂层耐腐蚀性能、耐磨性能、硬度、疲劳强度等性能的影响;其次从实际应用出发介绍了激光熔覆技术在液压支架修复上的使用情况,探讨了适用于液压支架不同部件的激光熔覆材料体系以及熔覆后涂层的性能表现情况;最后对激光熔覆修复液压支架未来的研究重点进行了总结与展望。
Coal mining hydraulic support is exposed to the harsh service environment of moisture and corrosion for a long time, and the surface is prone to corrosion and wear. Laser cladding technology provides an efficient and high-quality surface repair method to improve the service life of coal mining hydraulic support. This paper reviews the research progress of laser cladding of hydraulic support. Firstly, the effects of laser cladding process and material system on the corrosion resistance, wear resistance, hardness and fatigue strength of the coating are introduced. Secondly, the application of laser cladding technology in the repair of hydraulic support is introduced from the practical application. The laser cladding material system suitable for different parts of hydraulic support and the performance of the coating after cladding are discussed. Finally, the future research focus of laser cladding repair hydraulic support is summarized and prospected.
