- Abstract
In this experiment, pure nickel, cobalt, chromium, aluminum, and bismuth powders were mechanically mixed for three hours in accordance with a certain ratio of powders. After the coating was formed on the surface of a stainless steel substrate of 310s by low-pressure cold spray technique and analyzed by SEM and EDS. The studies show that the NiCoCrAlY alloy coating prepared by cold spraying has some pores and impurities, the powder particles are not melted, and the voids of the NiCoCrAlY alloy coating after vacuum heat treatment at 600° C./4 h are significantly reduced and the elements in the coating but the diffusion area is shallow.
