The Structure-Phase Compositions and Properties of Plasma-Detonation Ni and Co-Based Powder Alloys Coatings

Abstract:

This paper presents new results of transmission electron microscopy (TEM), X-ray diffraction (XRD) and atomic force microscopy (AFM) investigation of the structure-phase compositions of thick (150 μm) coatings on the base of Ni and Co deposited by plasma-detonation on steel substrates. The phase structures and morphology of precipitation from solid solution are defined. Factor k is defined in the Hall-Petch equation for the coating materials. The existence of a diffuse zone in the coating layer next to the substrate is established, the thickness of this zone is defined.
