摘要
对45钢表面电镀硬铬层后,在熔渣中向45钢表面的电镀硬铬层渗硼获得了硼化铬覆层。采用光学显微镜、XRD和电子探针等手段对获得的覆层的相结构进行分析。结果表明:覆层为多层结构,主要由CrB2和CrB相组成,具体组成取决于渗硼温度和时间。为了得到与基体结合良好的覆层,渗硼处理温度应控制在900~1000℃,渗硼时间控制在4~6h。
Chromium boride has been obtained by salt-bath boriding on chromium electroplated 45 carbon steel. The phase of the boronized layer was analyzed by microscope, XRD and EPMA. The results show that the boronized layer has multi-layer phase structure of CrB_2 and CrB. To obtain better layer, the boronizing process is controlled at 900~1000℃ for 4~6h.
