The PS-PVD method - formation of columnar TBCs on CMSX-4 superalloy

Purpose: The new plasma spraying method.Design/methodology/approach: The single crystal CMSX-4 nickel alloy was used as base material. The diffusion aluminide layer was deposited during the CVD process and was used as bond-coat. The zirconium oxide stabilized by yttrium oxide was utilized as the deposition material.Findings: It was proved, that there is a possibility of obtaining the ceramic layer using the PS-PVD process.Research limitations/implications: The thickness analysis and the chemical composition analysis by light and scanning electron microscopy were performed.Practical implications: This process can be used in aerospace industry to form oxidation resistant coatings.Originality/value: In article Plasma Spraying Physical Vapour Deposition Process was described.
