摘要

采用等离子表面合金化技术在不锈钢表面制备含Nb合金层

分析了典型渗层的显微组织形貌、成分分布及相结构

考察了含Nb含金层的腐蚀性能。结果表明

优化的工艺参数为:温度1100℃、工作气压80 Pa、保温时间3 h、源极电压900–700 V、阴极电压600–450 V。含Nb合金层厚度为60μm

表层Nb含量可达50%左右

呈梯度下降分布特征

表层主要由NbC、Nb6C5、Cr2Nb、Fe2Nb等相构成。相比不锈钢基体

Nb合金化后耐晶间腐蚀性能和均匀腐蚀性能均得到提高。

Abstract

Nb alloyed layer was prepared by plasma surface alloying technology on surface of stainless steel substrates.Microstructure morphology

depth profiling of the elemental composition and phase structure of the alloyed layer were analyzed.Corrosion performance of the Nb alloyed layer was investigated.The results show that the optimum parameters were: temperature

1100oC;air pressure

80 Pa

holding time 3 h

source voltage

900–700 V;and cathode voltage

600–450 V.The thickness of Nb alloyed layer was about 60 μm.The alloyed layer was mainly composed of NbC and Nb6C5

Cr2Nb and Fe2Nb.The surface Nb content was 50%

which decreased sharply in the first several microns of depths and then gradually in further depths.The Nb alloyed layer has improved resistance to intergranular corrosion and uniform corrosion.
