Tribological Behavior of Plasma Sprayed Al2O3/TiO2 Coatings under Liquid Paraffin Lubrication
|
Abstract:
Two types coatings derived from nano-sized and micro-sized Al2O3-13%TiO2 feedstock were fabricated on stainless steel substrates using air plasma spraying.Their tribological properties under liquid paraffine lubricated conditions were investigated by a SRV friction and wear instrument sliding against stainless steel ball.The results showed that the friction coefficient of nano-sized coating was 1/3 as low as that of micro-sized coating.More importantly,the wear resistance of nano-sized coating was increased...
