Sažetak
Properties of electroless deposited nickel - phosphorous coatings on austenitic stainless steel substrate were investigated. The main study has been focused on influence of heat treatment on microhardness and microstructure analysis of electroless Ni-P coatings. Nickel - phosphorous coatings was deposited without nickel strike pre-coating treatment. The electroless Ni-P layer has been deposited on stainless steel as substrate. The sodium hypophosphite has been used as reducing agent. Microstructure and morphology of the electroless treated specimens were analyzed by optical and scanning electron microscopy. Adhesivity was estimated by Vickers indenter. Based on experimental results, it can be concluded that heat treated electroless nickel - phosphorous coatings have higher microhardness than non-heat treated electroless nickel - phosphorous coatings. Analyze of Vickers indentation results showed that proposed electroless process gives satisfied results.
