Analysis and Comparison of Microstructure and Properties of 2Cr13 Stainless Steel and Its Laser Hardened Layer
摘 要
采用半导体激光器对不锈钢2Cr13进行表面淬火。分析了淬火层的微观组织、显微硬度及抗磨损性能等。结果表示：2Cr13不锈钢经过激光淬火后，基体到淬火层的耐蚀性逐渐增强，从基体到淬火层的显微硬度呈纵向增加规律，最高的显微硬度为713.1 HV0.2，是2Cr132不锈钢的3.24倍。淬火层冲击凹坑深度约62 μm，直径约4.9 mm，而基体2Cr13冲击凹坑深度约85 μm，直径约5.6 mm，在相同的冲击功作用下，淬火层的抗冲击韧性高于基体的。淬火层耐磨性能是基体2Cr13不锈钢的54.3倍，淬火层的磨损机理主要是显微犁削和黏着磨损。激光淬火水轮机用不锈钢2Cr13可显著提高基体的抗磨损性能，具有广泛的应用前景。

Abstract
The stainless steel 2Cr13 for steam turbine blades was surface-hardened with a semiconductor laser. Characterization and analysis of the microstructure, phase transformation, microhardness and wear resistance of the quenched layer were carried out. The results showed that after laser quenching of 2Cr13 stainless steel, the corrosion resistance of the substrate to the quenched layer gradually increased, and the microhardness increased from the substrate to the quenched layer in a longitudinal direction. The maximum microhardness was 713.1 HV0.2, which was 3.24 times that of 2Cr13 stainless steel. The depth of the impact pit of the quenching layer was about 62 μm and the diameter was about 4.9 mm, while the depth of the impact pit of the base 2Cr13 was about 85 μm and the diameter was about 5.6 mm. Under the same impact work condition, the impact toughness of the quenching layer was higher than that of the substrate. The wear resistance of the quenched layer was 54.3 times that of the base 2Cr13 stainless steel. The wear mechanism of the quenched layer is mainly micro-ploughing and adhesive wear. The stainless steel 2Cr13for laser quenching hydraulic turbine could significantly improve the wear resistance of the substrate, and had a wide application prospect.
