Structural features and wear resistance of the TiAlN coating formed on the Ti–6Al–4V alloy by combining electric arc spraying and gas nitriding methods
The formation of the TiAlN coating on Ti–6Al–4V alloy by combination of the arc spraying and gas nitriding methods was investigated. It was established that the TiAlN phase is formed in the coating during gas nitriding of the titanium alloy with a pre-sprayed layer of aluminum and titanium. By increasing nitriding temperature from 650 to 850°C, the content of the TiAlN phase decreased. The TiAlN coating significantly increases the surface hardness of the alloy (up to 12–15 GPa), and in a tribo-pair with Al2O3 provides significantly higher wear resistance compared to the TiN coating and untreated alloy.
