Improvement in the Oxidation Resistance of 1Cr18Ni9Ti by a Micro-crystalline MA956 ODS Alloy Coating

Corrosion and Protection Center, UST Beijing, Beijing 100083, China

摘要: 采用高頻電脈沖沉積技術在1Cr18Ni9Ti不銹鋼表面上沉積了厚度約為50μm的MA956 ODS合金納米微晶涂層、涂層與基體之間呈現良好的冶金結合.在1000℃靜態空氣中對1Cr18Ni9Ti試樣與表面施加涂層試樣進行了總計100h的恒溫氧化實驗.用AFM,SEM,EDX和XRD分別對涂層和氧化后試樣的形貌。成分和組成進行了觀察和分析.結果顯示:1Cr18Ni9Ti表面沉積MA956ODS。合金納米微晶涂層促進了Cr的選擇氧化,提高了1Cr18Ni9Ti表面氧化膜的粘附性,改善了1Cr18Ni9Ti抗高溫氧化性能.

Abstract: A micro-crystalline MA956 ODS alloy coating of about 50mm thick was developed on the 1Cr18Ni9Ti stainless steel by means of a high-frequency electro-spark deposition technique. The coating has a very fine grain size of about 100 nm and excellent metallurgical bonding with the substrate. Isothermal oxidation in air at 1000℃ for 100 h shows that the micro-crystalline MA956 ODS alloy coating on 1Cr18Ni9Ti promoted the selective oxidation of Cr and also improved the scale spallation resistance dramatically, thus increased the oxidation resistance of 1Cr18Ni9Ti greatly.
