Journal ArticleDOI
Structure and phases in nickel-base self-fluxing alloy coating containing high chromium and boron
TL;DR: In this paper, the structure of a nickel-base, self-fluxing alloy coating, containing chromium and boron thermal sprayed and fused, was investigated by x-ray diffraction (XRD), scanning electron microscopy (SEM), electron probe microanalysis (EPMA), and transmission electron microscope (TEM).
Journal ArticleDOI
Thermal-sprayed Fe-10CM3P-7C amorphous coatings possessing excellent corrosion resistance
TL;DR: In this article, an alloy of Fe-10Cr-13P-7C was thermally sprayed by three different processes: (1) 80 kW low-pressure plasma spraying (LPPS), (2) high-velocity oxyfuel (HVOF) spraying, and (3) 250 kW high-energy plasma spraying(HPS).
Journal ArticleDOI
Properties of Cr3C2-NiCr cermet coating sprayed by high power plasma and high velocity oxy-fuel processes
TL;DR: In this paper, the hardness and shear adhesion strength of Cr3C2-NiCr cermet coatings were investigated for a mild steel substrate by 200 kW high power plasma spraying (HPS) and high velocity oxy-fuel (HVOF) processes.
Journal ArticleDOI
Corrosion Resistance of Fe-16%Cr-30%Mo-(C, B, P) Amorphous Coatings Sprayed by HVOF and APS Processes
TL;DR: In this article, two kinds of Fe-16%Cr-30%Mo-(C,B,P) alloy powders having high ability to form an amorphous phase were thermal sprayed onto mild steel substrate using HVOF and APS processes.
Journal ArticleDOI
Characterization of plasma sprayed Fe-10Cr-10Mo-(C,B) amorphous coatings
TL;DR: In this paper, the as-sprayed amorphous and tempered crystalline coatings containing carbon and boron were shown to have a hardness of more than 1000 DPN, even on tempering at temperatures of 1073 K or higher.
