Özet

The effects on. fretting fatigue strength of manganese phosphate coated and uncoated AISI 1045 steel were investigated in this study. The results showed that the fretting fatigue limit of phosphate coated specimens was higher compared with uncoated specimens since the manganese phosphate layer occurring on surface decreased the friction force and friction coefficient in contact region. However, the plain fatigue limit did not increase because the surface compressive residual stress did not occur on the surface and the hardness did not change. The phosphate coating treatment delayed the oxidization of particles separated from contact region, which resulted in the increase of the fretting fatigue limit.
