摘要: This paper reports on characteristics of alumina-type coatings deposited steel substrates and treated with pulsed plasma streams containing high-energy ion beams (N, Ar, Ti+N). Originally matted surfaces the ceramic layers, which were created by spraying gray alumina, changed into shiny ones, splat boundaries disappeared due to melting a thin surface layer. The thickness this modified layer did not exceed 1 µm. A higher content Ti was found Ti- N-treated samples only.
