In the article, the authors examined the technological aspects of obtaining a functional alloy based on silver alloyed with chromium, zirconium, rhenium and rare earth elements (cerium, lanthanum, yttrium). A technology has been developed for producing powder from this alloy and nanostructured functional coatings based on it using the method of cold gas-dynamic spraying.

Cold Gas Dynamic Spraying (CGDS) has been developed to fabricate surface coating as a new technique in recent years. In this paper, aluminum bronze particles were sprayed on 45 steel and 316L stainless steel by CGDS, and the coating was sucessfully fabricated on the surface of the steels. The microstructure of the coating and the interface between the coating and the substrate were investigated by scanning electron microscope (SEM), energy dispersive (EDX) and XRD. It was found that the coating was dense and its porosity was low, while the microhardness of the coating was lower than that of the bulk one; Mechanical bonding was the main formation mechanism of the coating, and there was metallurgical bonding too; Diffusion occured at the interface between the coating and substrate; α phase in aluminum bronze particles transformed to β phase after the spray and the transformation was induced by the plastic strain during spraying.

The NiCoCrAlY+WC12Co coating with high density was prepared on the surface of the magnesium alloy by cold spraying. Effects of the WC12Co content on the wear behavior of coating were studied. The results showed that, under the dry friction condition, the weightlessness of wear of the coating with 20%WC12Co was smallest. The weightlessness of wear of the coating with 10%WC12Co was worse than that with 20%WC12Co. However, the weightlessness of wear of the coating without any WC12Co was worst among the three coatings. After the frictional experiment for 20 minutes, the weightlessness of wear of coating without any WC12Co was 10mg. Compared with that of coatings with 10%WC12Co and 20%WC12Co, the weightlessness of wear was lower than 35% and 54%, respectively. Obviously, the coating with 20%WC12Co had the capacity of the weightlessness of wear resistance. Consequently, the more the coating with WC12Co was, the higher the capacity of the weightlessness of wear resistance was.
