Abstract Scope Lightweight alloys of Aluminum (Al) and Titanium (Ti) are the major components of space systems because of their high strength to weight ratio. However, their poor tribological response in the presence of lunar regolith results in premature failures. Boron Nitride(BN) reinforced titanium coatings were produced by plasma spray method at low and high-volume percentage concentration of BN to counter this undesirable result, after powder preparation by cryo-milling. The microhardness results showed that coating hardness was 3 times that of conventional Ti6Al4V (335HV) substrate in the case of low vol.% hBN (1134 HV) concentration and, 1.5 times in the case of high vol.% hBN coating (516 HV). Tribological characterization by ball on disk tests revealed a 50% reduction in friction coefficient and absence of wear scars on the titanium coatings compared to conventional material. Coatings will be subjected to simulated lunar conditions in a custom-made erosion test rig in the future work.
