Growth Characteristics and Kinetics of Niobium Carbide Coating Obtained on AISI 52100 by Thermal-reactive Diffusion Technique严绍进1,王洪福1,2,SUN Qikun2,HE Peng2,PANG Chengang3,WANG Huachang2,WANG... and Resources Utilization of Ministry of Education, Wuhan University of Science and Technology摘 要:Niobium carbide coating was produced by thermal-reactive diffusion......
of oxide scale, which can effectively hinder the diffusion of oxygen. Whereas, reaction of Zr with oxygen leads to the formation of ZrO2 precipitates for the Ti-22Al-21Nb-6Zr alloy, which promotes the oxygen ingress into the substrate. Meanwhile, oxidation affected zones, including internal-oxidation layer and oxygen-enriched zone, are present beneath the outmost oxide scale. The difference......
