The influence of production method on oxidation resistance of the aluminide coatings obtained on IN 100 alloy

Purpose: The comparison of three deposition of coatings method.Design/methodology/approach: The diffusion aluminide coatings were deposited using the pack cementation, out of pack and CVD method.Findings: The authors present in the article the results on influence of the method of manufacturing the aluminide coatings on their microstructure and oxidation resistance.Research limitations/implications: The thickness analysis and the chemical composition analysis with a use of light microscopy, scanning electron microscopy and EDS analysis were performed.Practical implications: This process can be used in aerospace industry to form oxidation resistant coatings.Originality/value: It has been proven, that the coating obtained with CVD method, despite its small thickness, was characterized by the best cyclic oxidation resistance.
