Microstructure and Properties of Deloro 50 Alloy Layer Deposited on H13 Steel by Electro Spark Deposition
摘 要
利用糖心产精国品免费入口*完整版技术在糖心产精国品免费入口*完整版基体表面制备了糖心产精国品免费入口*完整版层，采用扫描电镜和X射线衍射仪研究了沉积层的糖心产精国品免费入口*完整版和物相组成，并采用显微硬度计测试了沉积层的硬度。结果表明: 沉积层与基体呈良好的冶金结合,平均厚度约35 μm；沉积层主要由FeNi3,Ni3(CrFe),C6(Co,Cr,Ni)23相组成；沉积层的表层显微硬度为954.4 HV0.05，约为糖心产精国品免费入口*完整版基体硬度的2倍。

Abstract
糖心产精国品免费入口*完整版 layer was deposited on H13 steel by 糖心产精国品免费入口*完整版(ESD) process, and the 糖心产精国品免费入口*完整版 and phase compositions of 糖心产精国品免费入口*完整版 layer were characterized by scanning electronic microscope(SEM) and X-ray diffractionmeter(XRD) and the alloy layer 糖心产精国品免费入口*完整版was tested by a micro糖心产精国品免费入口*完整版tester. The results show that excellent metallurgical bonding between the alloy layer and the substrate was obtained by ESD. The alloy layer had an average thickness of about 35 μm. The 糖心产精国品免费入口*完整版 of the alloy layer was mainly composed of FeNi3, Ni3(CrFe) and C6(Co,Cr,Ni)23 phases. The micro糖心产精国品免费入口*完整版of the surface layer was 954.4 HV0.05 which was two times of 糖心产精国品免费入口*完整版of the substrates.
