METHOD OF LAPPING PRESSURE-TIGHT JOINTS Russian patent published in 2004 - IPC

Abstract RU 2233215 C2

FIELD: grinding and polishing.

SUBSTANCE: parts to be jointed are made of metals of different rigidity. Hollows are made on the surface of the member made of more rigid metal, the total area of hollow being 80-90% of the joint area. One of the parts are covered with a technological composition, and lapping is produced with mutual rotation and forcing to provide selective transfer of the more soft metal to the surface and in the holes of the part made of more rigid metal.

EFFECT: enhanced efficiency.
