| 摘 要： | 采用Langmuir探针测定了不同磁场闭合状态下辉光放电环境中的电子温度(Te)、电子密度(ne)及离子密度(ne)空间分布状态,探讨了磁场闭合度对CrNx镀层沉积效率的影响机理.结果表明:三种磁场闭合状态下,电子温度都在靶面处最高,相邻靶间对称面最低,真空腔内部出现一个直径约240 mm的均匀中心区域;电子密度和离子密度在三种条件下均于真卒腔中心处最高,边缘处最低,而随磁场闭合度的整体变化规律表现为这两个参数值在不闭合状态时小于半闭合和完全闭合状态时;完全闭合状态下镀层的厚度明显大于半闭合和不闭合状态下的镀层厚度.

| Abstract: | Langmuir probe was used to analyze the distribution feature of electron temperature(Te),electron density(ne) and ion density(ni) in the circumstance of electric discharge at different closed-state of magnetic field.The influence of closed-state of magnetic field on deposition efficiency of CrNx coatings was discussed.The results indicate that the highest Te occurs on the target surface but the lowest between the neighboring targets in the experimental conditions,and an uniform distribution area of electron ... |
