Refractory metals are very sensitive to their surface condition. Removing microcracks, scratches, and other surface defects leads to an increase in their strength and ductility and lowers the ductile-to-brittle transition temperature [1], On the other hand, working media, surface films, and special coatings affect the surface condition and, consequently, mechanical properties of metals [2, 3], Especially interesting in this context are studies of the effect of thimetal coatings leading to an increase in the strength and ductility of metals and alloys.
