Abstract
Manganese Phosphate is an Industrial coating used to reduce friction and improve lubrication in sliding components. In this study, the tribology behavior of uncoated, manganese phosphate coated, Manganese Phosphate with oil lubricant AISI D2 steels was investigated. The Surface morphology of manganese phosphate coatings was examined by scanning electron microscope (SEM) and Energy dispersive X-ray Spectroscopy (EDX) .The wear tests were performed in a pin on disk apparatus as per ASTM G-99 Standard. The wear resistance of the coated steel were evaluated through pin on disc test using a sliding velocity of 0.35 m/s under normal load of 5 to35 N and controlled condition of temperature and humidity. The Coefficient of friction and wear loss were evaluated. Based on the results of the wear test, the manganese phosphate with lubricant exhibited the lowest average coefficient of friction 0.13 and the lowest wear loss 0.4 mm3 under 35 N load.
