FIELD: process engineering.
SUBSTANCE: invention relates to electric arc deposition of coats and may be used in machine building in production of wear-resistant cutting tools. Proposed method consists in placing titanium disk secured on current conducting mandrel and graphite electrode into tank filled with distilled water, feeding electric current and rotating titanium disk at constant rpm. Note here that clearance between said disk and said electrode is kept sufficient to ignite electric arc and produce uniform coat on titanium carbide disk cylindrical surface by plasma-chemical reaction of titanium and graphite evaporation.
EFFECT: lower costs, maximum mechanical hardness and strength.
