摘要
研究了Cr12MoV钢经激光表面淬火处理后的显微组织及耐磨性。结果表明,该钢经激光表面淬火处理后得到淬火层、高温回火层和基体三层不同的组织。淬火层的品粒细小,由隐晶马氏体及弥散分布的碳化物和残留奥氏体组成;淬火层具有较强的抗塑性变形和抗粘着磨损能力。
This paper deals with the microstructure and wear resistance of Crl2MoV steel after laser surface hardeaing. The experimental results show that the three-layer structure is found after laser surface hardening, i. e. hardened layer, high temperature tempered layer and substrate. The hardened layer has fine grains, and is composed of cryptocrystalline martensite. dispersed carbides and retained austenite。 The hardened layer has better plastic deformation resistance and adhesive wear resistance properties.
