The wear property of plasma sprayed Nano-structured Al2O3-13%TiO2coating
Nano-structured Al2O3-13%TiO2 coating was deposited by air plasma spraying.Wear properties of the coatings under different load trough SRV friction and wear testing machine were studied,the results showed that wear mass loss of A12O3-13%TiO2 coating by plasma spraying slide with ZrO2 and Si3N4 increase with load increasing,but the difference is that wear loss of coaing slide with Si3N4 is lower than the coating slide with ZrO2 when load is less than 40N.Opposite phenomenon will occur when load is higher than 40N.The wear surface morphology was analyzed trough scanning electron microscopic,the results showed that coating slided with Si3N4 ball when matching at low loads,with a shallow furrow shape grinding.There were wide and deep furrows while at higher loads.Coating slide with ZrO2 ball has no obvious cracks,no layer spalling.Wear was occurred by micro cutting.
