Abstract
Metal suicides are potential materials because of their excellent properties such as corrosion resistance, oxidation resistance and wear resistance. In this study, the authors propose a new surface treatment process to form metal suicides on metallic materials by using an atmospheric controlled IH-FPP. Atmospheric controlled IH-FPP in which Si particles are bombarded to the substrate with an elevated temperature of 1173 K can form the iron silicide. Elevated temperature of the substrate enhances transfer of Si particles on the substrate, followed by mixing and/or diffusion into the substrate. This results in the formation of iron silicides. Atmospheric controlled IH-FPP with Si-Cr mixed particles also forms the iron silicide. Atmospheric controlled IH-FPP with the mixed particles followed by annealing of 873 K for 3600 s forms chromium silicide in accordance with Fe-Cr-Si ternary phase diagram. Carbon steel materials covered with the silicide layer exhibit better corrosion resistance since SiO2 is formed on the silicide.
