Technology of applying of protective refractory coatings on foundry equipment
The applying technology of protective refractory coatings for foundry equipment by electro-chemical-mechanical method is presented. The method provides forming, compaction and hardening of fi re-resistant layer under the influence of current flow. Designs of the anode and the rotating cathode provide high precision (to 0.1 mm) of coating thickness on surfaces of any complexity. Technology is tested for compositions including refractory filler-electrolyte - binder and hardener.
