METHOD OF APPLYING METAL COATING ON THE SURFACE OF POWDERS AND SUBSTRATES Russian patent published in 2000 - IPC

FIELD: metal coatings. SUBSTANCE: invention relates to technology of deposition of metal coatings on surfaces of a variety of materials (powders and substrates), including dielectrics, semiconductors, and metals, and can be, for instance, used for metallization of abrasive grains, for applying metal coating on the surfaces of ceramics, to manufacture metal-ceramics-type composites, and also in electronics when manufacturing heat channels and other appliances. More particularly, material surface is degreased and cleansed and thereupon particles of substances selected from group including metals, alloys, metal oxides, metal hydroxides, metal sulfides are mechanically laid onto surface, which is then heated to 200 to 500 C under nonoxidation atmosphere. EFFECT: enabled inexpensive dense, strong coating with controlled thickness. 10 cl, 4 ex
