摘　　要：用双辉等离子渗金属技术,在880～900 ℃温度下,对T10钢进行了表面渗铬试验;分析了渗铬改性层的表观形貌和相结构,测量了渗铬改性层的成分。结果表明,在880～900 ℃温度下,对T10钢进行双辉等离子渗铬,可得到铬沉积层、铬渗镀层等形式的渗铬改性层。通过调节工艺参数,可对渗铬改性层形式进行控制。Double glow plasma chromizing process for T10 steel under 880～900℃ was studied. The distributions of carbon and chromium concentration were measured. The surface micrographs and phase structure in chromizing layer were analyzed. The results showed that for T10 steel in double glow plasma chromizing process, some forms of chromizing layers such as chromium depositing layer, chromium diffusing layer and chromium diffusion-depositing layer can be formed by adjusting the process parameters.
