Comprehensive analysis of the microstructure and mechanical properties of deposited metal of nickel high-temperature alloy ZhS32
During industrial use of the microplasma powder metal deposition (MPD) process at the E.O. Paton Electric Welding Institute, positive experiences with Ni-based superalloy ZhS32 restored edges on aircraft blades were confirmed. A comprehensive analysis, including optical and scanning electron microscopy, and mechanical property studies, aimed to improve the repair area’s characteristics and expand the range of parts repairable by MPD. The study examined the ZhS32 alloy’s structural states after deposition, aging, and homogenisation heat treatments.
