摘要 为提高Inconel 690合金管表面的耐蚀性和耐磨性,对合金管表面进行了激光熔凝渗氮处理,对处理后试样的微观组织、相组成、显微硬度及耐蚀性能进行了测试与分析,研究结果表明,激光氮化层主要由CrN、γ相等物相组成,氮化层具有较高冶金质量且无裂纹、气孔等缺陷,组织分布均匀、晶粒细小,显微硬度最高达到253 HV。经过激光熔凝渗氮处理后,合金管对Cl^-表现出较好的腐蚀抗性,但对OH^-的耐蚀性能轻微降低。 In order to improve the corrosion resistance and wear resistance of Inconel 690 alloy tube surface, the laser-fused assisted nitriding treatment to alloy tube surface is investigated. The microstructure, phase composition, microhardness and corrosion resistance of samples after treatment are tested and analyzed. The results show that the laser nitriding layer is mainly composed of CrN and 7 phases which has good metallurgical quality without defects such as cracks and pores and the microstructures uniformly distribute with fine grains. The laser-fused assisted nitriding layers have the highest microhardness of 253 HV. After the laser-fused assisted nitriding treatment, the alloy tube has better corrosion resistance to Cl^- ions with slight reduction of corrosion resistance to OH^- ions.
