An analysis of properties of electroless Ni-P layer on stainless steel

Properties of electroless deposited nickel - phosphorous coatings on austenitic stainless steel were studied. The electroless Ni-P layer has been deposited on stainless steel AISI 316 as substrate. Nickel - phosphorous coatings was deposited without nickel strike pre-coating treatment. Study has been focused on influence of heat treatment on adhesivity, microhardness and microstructure analysis of electroless Ni-P coatings. Adhesivity was estimated by Vickers indenter. Microhardness was tested by using scanning electron microscope. Microstructure of the electroless treated specimens were analyzed by optical and scanning electron microscopy. Based on experimental results, it can be concluded that heat treated electroless nickel - phosphorous coatings on austenitic stainless steel have higher adhesivity and microhardness than non-heat treated electroless nickel - phosphorous coatings.
