The Tribological Characteristics of Electroless Ni-P Coated AISI1020 Carbon Steel
AbstractThe effects of phosphorus content of electroless Ni-P (EN) coatings on the tribological and morphological properties of AISI1020 carbon steel were investigated. For this purpose, AISI1020 carbon steel substrates were coated with low, medium and high phosphorus EN coatings. Coated samples were characterized using surface roughness and micro hardness measurements, pin-on-disc wear tests, optical microscopy and scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM/EDX). The hardness and wear resistance of the EN coatings increased depending on decreasing phosphorus content of the coatings. Also, it has been found that the increase in the phosphorus content of the coating improves its friction properties
