Special features of electron beam technology of production of hard gradient coatings based on the titanium carbide with the Cr addition, and the characteristics of these coatings

摘要

The production of hard gradient coatings by electron beam remelting and condensation in vacuum of the appropriate mixtures of the powders is a relatively new and insufficiently examined method. In Ref. 1 and 2, the method was used for the deposition of coatings based on Cr carbide and Ti carbide. This work is a continuation of the examination of coatings based on titanium carbide. The coatings based on titanium carbide include the more complicated system Ni-Co-Cr-Ti-C produced by adding Cr to the Ni-Co-Ti-C system [2]. This additions result in significant changes in the properties of the coatings.
