以不同温度和时间对20CrMo钢表面进行了固体渗硼试验。用扫描电子显微镜(SEM)对渗层横断面进行了显微组织观察,用X射线衍射仪(XRD)分析了渗层的相结构,显微硬度计测试渗层的硬度分布,并对基体及渗层进行快速磨损试验及电化学极化曲线测试。结果表明,渗硼层厚度均匀,主要由FeB和Fe2B两相组成,且渗层显微硬度值最高达1090HV0.1,有很高的耐磨及耐蚀性能。 Solid boronizing tests on 20CrMo steel were performed at different temperatures and times. The microstructure of the layer was observed by scanning electron microscopy (SEM). The phase structure of the layer was analyzed by X-ray diffraction (XRD). The hardness distribution of the layer was tested by microhardness tester. Penetration layer for rapid wear test and electrochemical polarization curve test. The results show that the boronizing layer is uniform in thickness and mainly composed of two phases of FeB and Fe2B. The hardness of the layer is up to 1090HV0.1, which has high wear resistance and corrosion resistance.
