摘要/Abstract

摘要： 为提高H13热锻模具的耐磨性能和耐腐蚀性能，利用激光相变硬化技术对H13钢进行处理，采用XRD衍射仪、光学显微镜、扫描电镜、显微硬度仪、电化学工作站及高温摩擦磨损试验机对其相结构、显微硬度、耐腐蚀性及耐高温磨损性能进行测试。硬化层由针状马氏体、板条马氏体和碳化物组成，硬化深度为0.71 mm，显微硬度约为750 HV0.3。在脱模剂溶液中，硬化层的自腐蚀电流密度比基材小一个数量级。硬化层高温磨损的质量为基材的7%，磨损机理以黏着磨损为主，同时伴有磨粒磨损和氧化磨损。

Abstract: To improve the corrosion resistance and wear resistance of H13 steel, the phase structure, microstructure, microhardness, corrosion resistance, and wear resistance of H13 steel before and after laser phase-change hardening were compared and analyzed by means of XRD diffractometer, optical microscope, scanning electron microscope, microhardness tester, electrochemical workstation, and high temperature friction and wear tester. The microstructures of hardened layers are composed of needle martensite, strip martensite, and carbide. The hardening depth is 0.71 mm. The microhardness of the hardened layer is about 750 HV0.3. In demolder solution, the self-corrosion current density of the hardened layers is one order of magnitude smaller than that of the substrate. The high temperature wear mass of the hardening layers is 7% of as-received H13 steel. The wear mechanism is mainly adhesion wear, while accompanies abrasive wear and oxidation wear.

Key words: hot-working die steel, laser phase-change hardening, friction-abrasion testing machine；electrochemical corrosion
