摘要
采用专用脉冲电源,以金属Zr为电极、45钢为基体在含C溶液中通过脉冲放电制备了ZrC陶瓷涂层,测定了涂层的厚度与硬度,探讨了峰值电流、脉冲宽度等工艺参数对涂层厚度与硬度的影响。结果表明,当峰值电流为16A或者当脉冲宽度为60μs时,ZrC涂层的硬度均能达到最大。
Using the pulse power,taking the hard metal Zr as electrode, 45 steel as substrate in the solution containing C through pulse discharge,ZrC ceramic coating was prepared. The microcosmic hardness and thickness of the coating were measured,the influnce of the process parameters of peak current and pulse width on the thickness of the coating was dissused.The results show that the hardness of ZrC ceramic coating reaches the maximum, when the value of peak current is 16A or when the value of pulse width is 60μs.
