Chemical vapor deposition of wear-resistant iron-nickel coating on precision parts of hydraulic systems

Formation of high strength and corrosion resistance composition cover on the surface of casting

“…The goal of the process is that 5-6% of the liquid glass is mixed with a powder, and produced porous powder sponge is drawn to working surface of cast mold or stuffing, mold is drained, is packed and filled with liquid metal [6]. As a result of the interaction between the liquid metal and the composite powder mold coating, surface alloyed high qualitical and high propertied coated cast is produced [7]. This method saves considerably more expensive alloying material compared to the volumetric alloying.…”
