| 摘要 | The modified Wagner's equation is deduced based on some assumptions and analysis of the Al content profiles in aluminide coatings formed on K465 alloy and pure Ni at 850 degreesC, 950 degreesC and 1050 degreesC for 5 h, respectively. The complicated composition and microstrurcture of K465 alloy are taken into account when deducing the modified Wagner's equation, by which the interdiffusion coefficients are calculated as functions of Al content in beta-NiAl phase as aluminide coatings. Calculated results show that the interdiffusion coefficients in beta-NiAl phase formed on K465 alloy are evidently less than those on pure Ni, and the interdiffusion coefficients in beta-NiAl phase formed on K465 alloy strongly depends on Al content. Effects of alloying elements and precipitates on the interdiffusion coefficients in beta-NiAl phase formed on K465 alloy are briefly discussed. |
