The nanohardness increased with the nitrogen dose increasing but decreased when the penetrating depth increased, which justified the relationship between the friction coefficients of the aluminium implanted with nitrogen and wear cycles under weak contact condition.
随着氮离子注入剂量的不断增加，铝试样的压痕硬度不断增加；而随着压入深度的增加，压痕硬度则不断减小。 离子注入后，硬度随注入剂量和压入深度变化的趋势较好的支持了有关弱接触情况下摩擦系数与摩擦圈数的关系。
