工件表面电沉积硬铬扩散强化技术

The Technology of Surface Strengthening by Using Fleet Electricity Deposited Cr Layer

介绍了工件表面快速电沉积硬铬层及采用感应加热使硬铬层铬元素向基体扩散,以提高工件表面硬度和耐磨性。除此之外,经微观分析可见,强化层和基体形成牢固的冶金扩散层。对涂层的组织性能研究表明,涂层具有较高的硬度和耐磨性。

The technique of fleet electricity deposited Cr layer in die was introduced, which can make up performance defects of die material in increasing performance of die such as hardness and resistance to wear. In this way, it was proved through the analysis of microstructure, Cr elements were proliferated into the body by adopt responding-heat and the layer combine with the body firmly by forming a metallurgy layer; So the hardness and resistance to wear of layer was improved.
