METHOD OF RECONDITIONING PARTS FROM ALUMINIUM ALLOYS Russian patent published in 2013 - IPC B23P6/02 

FIELD: process engineering.

SUBSTANCE: invention relates to reconditioning and repair of metal parts and may be used machine building, etc. Proposed method comprises the following jobs: first, parts surfaces are machined to resume their initial shape. Then, they are sand-blasted and processed by micro arc oxidising in water solution of caustic potash 10-20 g/l and liquid glass 10-20 g/l at 35-45°C and current density of 20-30 A/dm² for 10-100 minutes. Then, coating is removed at local sections with diameter of 3-6 mm and total area making 20-30% of surface are to be reconditioned. Then, aluminium alloy of the part grade is spayed on said surfaces in crucible dip-forming. Now sprayed layer is rolled to shape and size the part by machining as required.

EFFECT: life not smaller than that of new parts.
