Purpose: The preliminary results of research on forming the aluminide coatings using CVD method were presented in the article. Design/methodology/approach: The coatings were obtained in low activity process on the surface of Rene 80 superalloy. The microstructure analysis and chemical composition analysis were performed applying different values of aluminizing process parameters. Findings: The authors present in the article the results of oxidation resistance analysis of aluminide coatings which were obtained on the surface of Rene 80 superalloy using various techniques. Research limitations/implications: The research results revealed the possibility of obtaining coatings by low activity aluminizing. Practical implications: This process can be used in aerospace industry to form oxidation resistant coatings. Originality/value: It was shown that the coating created during the CVD process was characterized by a good oxidation resistance at the temperature of 1100°C.
