本文对四种相同能量、不同剂量氮离子注入的GCr15钢表面形成的石墨碳层进行了Auger研究。Auger剖面谱图的结果表明此碳层厚度与氮离子的注入剂量成正比。与摩擦磨损实验结果比较,发现摩擦系数在随时间变化曲线的初期,小于0.20,即离子注入过程中钢表面形成的碳层有助于减小摩擦系数。

The carbon layers on implanted steel surface have been studied by means of Auger spectra. It is shown that the thickness of the carbon layer is proportional to the dose of implanted ions. By comparison with the results of friction and wear tests, the friction coefficient is smaller than 0.20 at the first part of the friction coefficient curve. It is considered that the graphitic carbon layer on the top of steel is helpful to reducing the surface friction coefficient of steel.
