“…For example, NiCrAlY and TiAlO composite coatings were deposited on Ti-6Al-4V by plasma spraying; 6 Ti-Cr-Al coatings were prepared on the near a titanium alloy TIMETAL 1100 by magnetron sputtering; 7 other protective coatings such as TiVCrAlSi high entropy alloy coatings by laser cladding, 8 ceramic coatings by microplasma oxidation and SiO 2 coatings by sol-gel method were also successfully produced on Ti alloys. [9][10][11][12][13] However, magnetron sputtering, laser cladding, microplasma oxidation and sputtering techniques require expensive processing equipment or involve complex processes and so their use in many fields is limited, 14 and coatings by sol-gel method are usually too thin for industrial applications.…”

Glass-quartz and glass-quartz-aluminium composite coatings were successfully produced on Ti-6Al-4V alloy by slurry method. The oxidation behaviour of the specimens at 800uC for 100 h was studied. Both composite coatings exhibited good high temperature oxidation resistance. After oxidation for 100 h, quartz and diopside were main crystalline phases in the glass-quartz composite coating. Some open pores appeared on the surface of the glass-quartz composite coating, which might be related to the intensive crystallisation of diopside in the composite coating. While in the glass-quartz-aluminium composite coating, no open pores could be seen, and some new phases such as silicon and alumina were observed. The silicon and alumina phases might be originated from the reaction between glass and molten aluminium. Because of this, incorporation of aluminium particles into the composite coating slows the nucleation and growth rate of diopside.
