PROCEDURE FOR APPLICATION OF METAL COATING ON MATERIAL IN FORM OF GRAIN POWDER OR GRANULES

摘要

FIELD: metallurgy. ^ SUBSTANCE: procedure consists in preliminary thermal and acidic treatment of material, in successive washing it with water and in sulphidation for application of current conductive film. Further, material is immersed into electrolytic solution avoiding its surfacing. Material immersed into electrolytic solution is periodically mixed till application of metal coating is completed. Electrolytic sedimentation is performed NëÑ1 times using poly-component electrolytic solution. After N-fold application of metal coating material is washed with water and is subjected to additional thermal treatment. ^ EFFECT: more uniform metal coating and its reliable adhesion with surface of material. ^ 3 cl, 1 ex
