Abstract A friction-seizure test procedure is proposed to analyze phosphate/stearate coating performance in relation to stressing conditions. Test results, including the occurrence of hydrodynamic lubrication, mixed lubrication and seizure at the slider/specimen coated interface, are related to effective phosphate bonding and to lubricant reactive effects. The soap settling process is analyzed in terms of seizure sensitiveness and coating aging is studied in relation to moisture content and temperature. The effects of coating surface temperature on the occurrence of lubrication type and seizure are also analyzed for reactive and unreactive soaps. Stressing conditions such as sliding velocity and contact pressure are studied and a coating behaviour law for seizure is finally proposed.
