METHOD FOR ABRASIVE-JET SHAPING OF LUBRICANT MICRO-RECESSES Russian patent published in 2006 - IPC B24C1/10 

Abstract RU 2283213 C2

FIELD: mechanic working of metals, namely abrasive-jet finishing, mainly of precision friction pairs.

SUBSTANCE: method comprises steps of working fixed sample by acting upon it with compressed air stream containing abrasive particles; measuring in fixed sample sizes of non-worked spots in static imprint of air-abrasive jet having axial percentage density of lubricant micro-recesses equal to 0.45; acting upon part surface with air-abrasive jet for shaping lubricant micro-recesses. Contour of air-abrasive jet is to be inside circle with radius r = 0.74R where R - radius of static imprint of air-abrasive jet on working plane. Working is realized while providing part oscillations with frequency 20 - 30Hz and with amplitude equal to half of specified dimension of non-worked spots in zone of static imprint of air-abrasive jet on fixed sample. Percentage density of lubricant micro-recesses is in range 0.45 - 0.25.

EFFECT: uniform distribution of lubricant micro-recesses.
