Nickel-based nanocrystalline samples and nickel- And palladium-based nanostructure amorphous samples were obtained by magnetron sputter deposition with following research. Both amorphous and crystalline particles have a size of ~10 nm. The grain size is increased by 1.5 times by increasing of spraying time from 1 to 5 minutes. Palladium is the potentialdefinition element in the researched system, which is explained by relatively high positive values of system electrode potential in initial (108 mV) and stationary (184 mV) states. Stable positive potential shift of the system, observed during exposure, indicates the formation of protective products of interaction with corrosive-active medium on the sample surface. Assessment of changes in sample weight showed that even under anodic polarization in the area, close to stationary corrosion potential, the dissolution rate in given biological corrosion-active environment is very low. Due to its unique properties, amorphous structure coating has broad application prospects. Due to its high corrosion resistance in Hank's solution, Pd - Zr coating can be particularly used as coating for bioimplantants. Due to their ramified surface and nanosizes, nickel- And palladium-based nanostructure and crystalline glasses can be used as catalysts for chemical reactions.
