摘要
选取了两种不同的合金粉末材料,采用激光熔覆技术,对内缸活塞杆表面进行了修复强化处理,对比分析了两种不同材料熔覆后的微组织、微硬度、耐腐蚀性和耐磨性,提出了两种不同熔覆材料修复的内缸活塞杆所适用的工作环境。研究结果表明,两种熔覆层材料均能有效提高内缸活塞杆表面的耐磨性、抗冲击性和抗腐蚀性。
With the laser cladding technology, two different types of alloy powders are chosen to repair the inner cylinder rod surface. The microstructures, microhardness, corrosion resistance and wear resistance of the cladding layers with two different types of powders are compared and analyzed. The suggestions are given in terms of the applicative working environments of the inner cylinder piston rods repaired with these two different cladding materials. The study results show that these two types of cladding layer materials can both effectively improve the abrasive resistance, impact resistance and corrosion resistance performances of the inner cylinder piston rod surfaces.
