WebIn high-temperature applications, premature failure of 4340 steel is associated with creep deformation [ 24, 25 ]. Therefore, this study aims to analyze the impact of self-fluxing coating applied by air plasma spray on AISI 4340 steel under creep conditions. The results are compared with the original steel substrate.
