A study on the tribological properties of low-pressure plasma-sprayed Al–Cu–Fe–Cr quasicrystalline coating on titanium alloy

A friction- and wear-resistant Al–Cu–Fe–Cr quasicrystalline coating was fabricated on substrate of titanium alloy by low-pressure plasma-spraying (LPPS) method. The LPPS Al–Cu–Fe–Cr quasicrystalline coating has a rapidly solidified lamellar microstructure consisting of mainly decagonal phase and sma...

Description
Summary:A friction- and wear-resistant Al–Cu–Fe–Cr quasicrystalline coating was fabricated on substrate of titanium alloy by low-pressure plasma-spraying (LPPS) method. The LPPS Al–Cu–Fe–Cr quasicrystalline coating has a rapidly solidified lamellar microstructure consisting of mainly decagonal phase and small amount of cubic phase peaks. The results showed that Al–Cu–Fe–Cr quasicrystalline coating improved the friction and wear resistance of titanium-based alloys under dry sliding wear test conditions. The excellent wear resistance may be attributed to the high hardness of Al–Cu–Fe–Cr quasicrystal.
