Fabrication and characterization of RF magnetron sputtered composite MoS₂ and ZrN coatings on Ti₃SiC₂ max phase for space applications

The lubrication effect of solid-based materials has been recognized for centuries, but their use as lubricants dates back to only about 50 years. Solid are used in applications where parts operate under severe operating conditions such extreme temperatures and very high vacuum. replace liquid based operation environmental that beyond the capability a liquid-based lubricant or vacuum, cryogenic temperatures, radiation, corrosive gases, fretting wear. Applications space mechanisms, satellites, vehicles, turbopumps, nuclear reactors, refrigeration plants, etc examples conditions. In this research, nano scale composite coatings MoS2with varied proportions ZrN (5%, 10% 20%) were deposited on Ti 3 SiC 2 Max phase substrate using Physical Vapour Deposition (PVD). PVD technique was RF magnetron sputtering process. Material characterization carried out Field Emission Scanning Electron Microscope (FESEM) Spectroscopy Energy Dispersive X-Ray (EDS). Addition ZrNis observed reduce porosity self-lubricating MoS coating.
