摘要：

Interdiffusion between a coating and its underlying substrate can change the oxidation properties of the coating and the mechanical properties of the coated material. An approach is given here for analyzing electron probe microanalyzer (EPMA) data in order to measure the amount of interdiffusion and to predict how interdiffusion can be reduced by changing the coating chemistry. The approach makes use of "zero flux planes" and "composition vectors". It is shown how to eliminate or reduce Kirkendall porosity in a systematic manner. Experimental results obtained on nickel base alloys are used for illustration.
