We present the results of the experimental investigation of the influence of the thickness of thin nickel films on their microstructure and mechanical properties. As the thickness of the films decreases, the deposits become more fine-grained, structurally defective and stronger. At the same time, they are characterized by higher internal stresses and smaller relative elongation. The coatings deposited by pulse currents are 2-2.5 times stronger than the coatings deposited by direct currents and the stabilization of their microstructural parameters is completed at a thickness of 4-5 mu m. Hence, the thickness of nickel coatings deposited by pulse currents can be decreased to the indicated values.
