The WC-Co coatings obtained with coarse or nano-powders were deposited on stainless steel substrates using air plasma spray technique. In conventional coating the microstructure was dominated by areas of amorphous matrix and block-type WC particles, while in nano-structured coatings amorphous areas of varying concentration of Co and W were prevailing. The presence of partly dissolved WC carbides, tungsten veins as well as nano-crystallites rich in either Co or W were also noted in both types of coatings.

PL

Powłoki WC-Co z gruboziarnistego lub nano-proszku naniesiono techniką natryskiwania plazmowego na podłoża ze stali nierdzewnej. Mikrostruktura powłok konwencjonalnych była zdominowana przez obszary o amorficznej osnowie i blokowe węgliki WC, podczas gdy powłoki z nano-proszku zawierały więcej obszarów amorficznych różniących się zawartością Co i W. W obu powłokach stwierdzono również obecność częściowo rozpuszczonych nieregularnych WC, żył wolframu oraz nanokrystalitów bogatych w Co lub W.
