Fe3Si films are deposited onto the Si(111) wafer using sputtering with parallel facing targets. Surface modification of the deposited Fe3Si film is conducted by using a microwave plasma treatment under an Ar atmosphere at different powers of 50, 100 and, 150 W. After the Ar plasma treatment, the crystallinity of the coated Fe3Si films is enhanced, in which the orientation peaks, including (220), (222), (400), and (422) of the Fe3Si are sharpened. The extinction rule suggests that the B2–Fe3Si crystallites are the film’s dominant composition. The stoichiometry of the Fe3Si surfaces is marginally changed after the treatment. An increase in microwave power damages the surface of the Fe3Si films, resulting in the generation of small pinholes. The roughness of the Fe3Si films after being treated at 150 W is insignificantly increased compared to the untreated films. The untreated Fe3Si films have a hydrophobic surface with an average contact angle of 101.70°. After treatment at 150 W, it turns into a hydrophilic surface with an average contact angle of 67.05° because of the reduction in the hydrophobic carbon group and the increase in the hydrophilic oxide group. The hardness of the untreated Fe3Si is ~9.39 GPa, which is kept at a similar level throughout each treatment power.

In the present work, the Cr-AlSi12 composite coatings were successfully synthesized on the Ti-6Al-4V alloy substrate by using the mechanical alloying method. The effects of raw Cr particle size, milling duration, and annealing treatment on the preparation of the coatings were investigated. The asprepared coatings consisted of the inner coating layer with coarse Cr particles and the outer coating layer with refined and highly homogenized structure. The annealing treatment could promote element diffusion and alloying; it was favorable to the densification and oxidation resistance of the coatings. There is a highly densified alloyed layer in the outer coating. The annealed coating showed excellent friction and wear resistance. After the oxidation process, the annealed coating showed the best high-temperature oxidation resistance. The oxidized annealed coating exhibited four layers, which included the thin Al 2 O 3 oxide film, the homogenized alloyed layer, the composite layer consisted of Al 2 O 3 and coarse Cr particles surrounded by alloyed layer, and the Al 3 Ti diffusion layer. This was favorable to the improvement of high-temperature oxidation resistance. The oxidation process of the annealed coating was elaborated.
