METHOD OF RECONDITIONING PARTS OF PAIRS OF FRICTION OF INTEGRAL STEERING MECHANISMS WITH STEERING BOOSTER Russian patent published in 2013 - IPC B23P6/00 B23H5/00 C23C4/04 

FIELD: process engineering.

SUBSTANCE: invention relates to reconditioning and repairing assembly units and parts and may be used at repair enterprises in reconditioning steering boosters. In compliance with first version, during replacement of seal in rod-cover joint, hydraulic cylinder rear cover worn-out bore is reamed to repair size while coating layer is applied on rod surface and shaft journal via intermediate layer. In compliance with second version, medium- or high-carbon steel coating is applied on slide valve surface by electric arc deposition while worn-out bore in cylinder body id reamed by diamond expansion reamers to apply the coating on slide valve worn-out fillets. In compliance with third and fourth versions, meta; coating is applied by electric arc machining while copper-bearing alloy later is applied on worn-out seats of worm shaft and worn-out surfaces of bores for pin in rack and rod. In compliance with fifth version, seals in piston-cylinder joint is replaced to hone cylinder worn-out bore to remove wear traces while rod working surface and thrust face surface are hardened by molybdenum electrode.

EFFECT: one-hundred-percent recovery.
