摘　　要：研究了化学热处理 (固体粉末法渗B) 310SS后在气氛总压为 10 5Pa的 2 .3%SO2 —S2 — 8.8%N2 环境中6 0 0℃下的高温腐蚀行为 .结果表明 ,固渗B在基体材料表面生成了 (Fe ,Ni) 2 B、(Fe,Ni)B ,影响了Cr元素在试样表面的分布 ,使渗B试样在腐蚀初期腐蚀速度较快 .固渗B涂层对 310SS抗高温气体腐蚀能力影响不大 .The high temperature corrosion behavior of 310SS (stainless steel) treated by boronizing in 2.3%SO 2/S 2/8.8%N 2 under 10 5 Pa at 600℃had been investigated.Boronizing treatment resulted in formation of (Fe,Ni) 2B and (Fe,Ni)B on the surface of 310SS.Corrosion of Boronizing sample showed rapid rate in initial stages for small of Cr in outer scale.However,the boronizing coating had negligible effect on the corrosion resistance of 310SS.
