The paper presents results of comparative tests concerning the effect of the morphology and particle size of the WC-Co-Cr coating material on the microstructure and mechanical properties of coatings sprayed (using the high velocity oxy-fuel method (HVOF)) on substrates made of magnesium alloy AZ31. The tests involved the use of two types of commercial powders, i.e. agglomerated and sintered powder (AS) (Höganäs, Amperit 558.074) and sintered powder (S) (Höganäs, Amperit 554.071). The microstructures of the coatings were observed using digital light microscopy and scanning electron microscopy. The tests also involved the determination of porosity and roughness as well as measurements of instrumental hardness (HIT) and Young’s modulus (EIT ). The microscopic observations revealed that the coatings were characterized by the relatively compact, dense and uniform structure as well as good adhesion to the substrate. The porosity of the S-type coating was approximately 1.5 times higher than that of the AS-type coating. In addition, the S-type coating was visibly thinner (than the AS-type coating), which could be ascribed to a lower powder feed rate applied during the spraying process. The surface of the AS-type coating was characterized by lower roughness (Ra = 4.5 ± 0.1 μm) than that of the S-type coating (Ra = 5.8 ± 0.3 μm). The differences in terms of instrumental hardness (HIT) and instrumental Young’s modulus (EIT) were also small. However, it could be noticed that the more compact structure and lower porosity of the AS-type coating resulted in the obtainment of slightly higher values of both HIT and EIT.

W pracy przedstawiono wyniki badań porównania wpływu morfologii oraz wielkości cząstek materiału powłokowego WC-Co-Cr na mikrostrukturę i własności mechaniczne powłok natryskiwanych płomieniowo naddźwiękowo (High Velocity Oxy-Fuel) na podłoże ze stopu magnezu AZ31. Do badań wybrano dwa rodzaje handlowego proszku: aglomerowany i spiekany (AS) – Höganäs, Amperit 558.074 oraz spiekany (S) – Höganäs, Amperit 554.071. Obserwacje mikrostruktur wytworzonych powłok wykonano przy użyciu mikroskopów: cyfrowego świetlnego oraz skaningowego elektronowego. Określono także porowatość i chropowatość oraz zmierzono twardość instrumentalną (HIT) i moduł Younga (EIT). Na podstawie wykonanych obserwacji mikroskopowych stwierdzono, że wytworzone powłoki charakteryzują się stosunkowo zwartą, gęstą oraz jednolitą strukturą i dobrze przylegają do podłoża. Porowatość powłoki S jest ok. 1,5 razy większa niż w przypadku powłoki AS. Ponadto charakteryzuje ją widocznie mniejsza grubość niż powłoki AS, co jest związane z mniejszym wydatkiem podawania proszku w trakcie procesu natryskiwania. Powierzchnia powłoki AS odznacza się mniejszą chropowatością niż powłoki S, odpowiednio: Ra = 4,5 ± 0,1 µm i Ra = 5,8 ± 0,3 µm. Różnice w wartości twardości instrumentalnej (HIT) oraz instrumentalnego modułu Younga (EIT) są również niewielkie, jednakże można zauważyć, że bardziej zwarta budowa oraz niższa porowatość powłok AS wpływają na uzyskanie nieznacznie wyższych wartości zarówno HIT, jak i EIT.
