Only a few studies (Ref. 1, 2) have been devoted to the boration of cobalt. I Attention has been given to a study of borating cobalt and alloys based;,/upon it due to the fact that one of the cobalt alloys (K&NJOIM) is used for tne manufacture of nonmagnetic, corroslöhäry stable springs and core samples of electrical measuring instruments. In addition, the Ixardness of core samples from this'alloy, which equals HRC 58-0I, is insufficient for certain instruments. Therefore it is of practical interest to study the possibilities of increasing the hardness of this alloy by means of boration.I BORATION OF COBALT IBoration was done by electrolysis in a melted drill and in a melted draw with the introduction of boron carbides (up to 30-40 $ by weight). The latter boration method i
