摘要

研究了Ｗ＋Ｃ双注入Ｈ１３钢在表面形成的抗腐蚀的优化表面层。电化学极化曲线测量结果表明双注入极化电流密度峰值随极化次数的增加而达到饱和，其饱和电流密度峰值比Ｈ１３钢的小１００倍以上，比纯Ｗ的小２－３倍。双注入次序对腐蚀特性也有影响，先注入Ｗ的Ｗ５Ｃ８样品比后注入Ｗ的双注入样品Ｃ５Ｗ５的极化电流密度峰值要小１倍。扫描电镜观察到样品腐蚀后的抗腐蚀结构。Ｘ射线分析表明这些结构是ＷＣ、Ｗ２Ｃ、ＦｅＷ、Ｆｅ２Ｗ、ＦｅＷ２Ｃ和铁的碳化物组成的。俄歇分析表明这种结构是多层结构的优化复合层，表面有一层薄碳层，在碳层下面是一层金属化合物的弥散层，紧接着又有一个铁的碳化物弥散层，这些结构具有良好的抗腐蚀特性。

Abstract

The surface layer optimized in resistance of corrosion and wear has been obtained by W+C dual implantation on H13 steel. The electrochemical polarization measurements show that the peak current density ID is increased and then saturated with increasing of voltage scanning loops. The ID is 100 times smaller than that of H13 steel

and 2-3 times smaller than that of tungsten. The influence of dual implantation order on corrosion resistance is also studied. The ID for W 5C 8 implanted first with W is half of that for C 5W 5 implanted first with C. The corrosion resistance structure of the samples after corrosion is observed by SEM. The X-ray analysis indicates that the structure consists of disperse phases of WC

W2 C FeW

Fe 2W

FeW 2C and iron carbides. It is shown from Auger analysis that the optimum complex layer for corrosion resistance consists of thin carbon film on surface

disperse phases of these metal compounds in middle and then iron carbides layer below.
