The authors report the results of finish treatment researches of surfaces of pistons made of aluminium alloys. It is shown that centerless polishing and polishing before coverage of surface with nickel-phosphorus alloy provides good durability of coupling of alloy with aluminium basis, and a chemical nickelage and polishing provide the increase of wearproofness and inoxidizability of coverage with the elastic circles of alloy. Results of the work reflected in the article are inculcated as technology of the chemical besieging and finish abrasive treatment of protective-decorative coverage of alloy nickel-rhenium-phosphorus in. “Compressor” Association LLC (city of Penza), application of which allowed to promote wearproofness and inoxidizability of working surfaces of details. An economic effect from introduction of development is attained by the increase of resource of work in 1,3–1,5 times.

Keywords: finish treatment, pistons, aluminium alloys, centerless grinding, polishing, coverage, an alloy is nickel-rhenium-phosphorus, chemical nickelage and polishing, elastic circles, wearproofness and inoxidizability of coverage.
