Taking Mo₂N-SiNₓ/Ag-SiNₓ mother-of-pearl multilayer self-lubricating films and ZrN-MoSN-Ag nanostructured thin films as examples this work mainly focuses on design preparation and high temperature self-lubrcation properties establishes design principles for broad-tempearture long-lasting solid lubricants through microstructure optimization and tribochemical mediation offering significant potential for extreme-condition applications.
