Titanium alloy has extensive applications in numerous fields, such as in aerospace, shipbuilding, petrochemical, and bio-medical. However, under the condition of high temperature (above 700 °C), it is difficult to meet the requirements of the performance of the turbine blades, piston rings, valves, etc. In this paper, the alloy powder is composed of Ni60A, TiN, Al, and Si in accordance with the proportion of 1:3:4:2 (mass ratio), and the composite coating, such as TiN, TiB, Ti5Si3, and Al3Ti were synthesized on Ti-6Al-4V alloy by Yttrium Aluminium Garnet(YAG) laser. The friction and wear experiments were carried out on Ti-6Al-4V alloy and alloyed coatings at different loads (3N, 6N, 9N), and different temperatures (25 °C, 350 °C, 700 °C). The impact of load and temperature on wear performance were analyzed by analyzing the friction traces. The results showed that the abrasion loss, wear width, and depth, wear volume, and wear ratio of the alloyed coatings were less than Ti-6Al-4V alloy, and the surface of furrow was shallow and the wear was less. However, under high temperature conditions, the alloy coating wears worse than Ti-6Al-4V alloy, and the high temperature wear resistance is not ideal.

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.

“…A deposição do silício puro ou liga à base de silício em processos de revestimentos para substratos de aluminetos de titânio formam camadas de revestimentos contendo fases do tipo TiSix, TiSi mais externas e na zona interdifusa substrato/revestimento fases TixSiy. Essas fases intermetálicas podem ser observadas nos campos bifásicos do diagrama de fases Ti-Si da Figura 20 (STERN, 1996;YU et al, 2015). Espera-se que os revestimentos formem camadas de óxidos protetora estável e amorfa de SiO2 resistente a oxidação/corrosão em alta ou baixa temperatura (STERN, 1996) e que apresente boa fluidez para ajudar no processo de cura das rachaduras (YU et al, 2015).…”
