Abstract
Transmission electron microscopy was used to study crystallization during heat treatment of intermetallic phases in a coating of the Ni–W system with 44 wt.% tungsten. Amorphous in the initial state, the coating crystallizes by various mechanisms depending on temperature. The structure of the resulting coatings is close to the structure of classical composite electrochemical coatings. The study of the structure of coatings annealed under various conditions made it possible to establish heat treatment modes for the formation of a structure that provides maximum microhardness.
