METHOD OF PROTECTION OF ULTRA-PURE SURFACES Russian patent published in 1995 - IPC

Abstract RU 2037746 C1

FIELD: mechanical engineering. SUBSTANCE: jet is formed from ultra-pure gas medium and surface is blown with this jet; surface being protected is placed in initial section of jet thus formed; length of this section is determined from the following formula: L KV; K = Z²/D, where V is velocity of gas jet at the end of surface protected; Z is half the branch pipe diameter; D is diffusion coefficient. EFFECT: enhanced efficiency. 1 dwg
