FIELD: electricity.
SUBSTANCE: increasing the values of switching power and the service life of electrical contacts with the proposed protective coating is the technical result of the invention. The protective coating of the electrical contacts is made on the basis of a binary electrolytic W-Ni alloy deposited on a nickel substrate in which the W content increases linearly from 0% at the edge of coating-substrate up to 50% at the outer edge of the coating, which provides high coating resistance to delamination.
EFFECT: improving the performance of mentioned devices.
