A method for the preparation and properties of an alloy based on nickel is discussed. An electrolyte for the deposition of a tin-nickel alloy has been developed. The influence of electrolysis regimes and electrolyte composition on the physical and mechanical properties (microhardness, spreading coefficient of solder, transient electrical resistance, coating ability to soldering, phase composition, porosity, adhesion, corrosion resistance) of an electrolytic coating based on nickel-tin alloy precipitated from a chloride electrolyte. The possibility of using a tin-nickel alloy as a solderable coating instead of gold and silver is shown.

In modern engineering the great attention is paid to the creation and implementation of new electroplating coating to ensure the durability, hardness and corrosion resistance. One of the effective methods for improving the properties of composite coatings is the method of galvanic deposition. The principle of obtaining of the composite electroplating was based on the fact that together with the metals ion some disperse particles of different sizes and nature are co-deposited. By including into metal matrix the particles are improve the performance coatings and increase the reliability and durability of products. The chloride electrolyte for application of the wear-resistant composite galvanic coating of nickel-cobalt-silicon oxide system was designed. The influences of the electrolysis modes and the electrolyte composition to a physical mechanical properties of the coating (wear resistance, firmness to corrosion, micro-hardness, internal stress, porosity, adhesion) were investigated. The possibility of the usage of received coating as the firmness to corrosion material with anti-frictional properties was showed.
