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.

利用表面分析技术(AES,XPS,SIMS)研究了经氮离子注入的外科植入材料Ti6Al4V表面成分与键合态,用轮廓仪的测量结果计算了氮离子注入深度及注入氮离子的Ti6Al4V的刻蚀速率。考虑到该合金的基体效应,对AES的定量结果进行了修正。结果表明,注入到合金中的氮离子与合金中的Ti形成高硬度的TiN,N的分布近似为Gauss形式,注入总深度约为350nm,在距表面约140nm处氮量最大,N与Ti的浓度比可达1.1。

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 techniques for surface analysis including AES,XPS and SIMS were employed to study the chemical composition and bond valence of nitrogen ion implanted surface of surgical implantation service alloy Ti6Al4V.The depth of implanted nitrogen ions and the sputtering rate of argon beams were determined using a profilometer.It was found that the combination of injected nitrogen ions with titanium resulted in the formation of hard TiN particles and the profile of nitrogen concentration approximately displayed gaussian distribution.The total depth of implanted nitrogen is about 350 nm and its maximum concentration appears in the depth of about 140 nm from the surface,in which the concentration ratio of nitrogen to titanium may be up to 1.1.
