Increase in operation period of the oil-field equipment at the expense of replacement the material of details

Time dependences of oxide coverings growth at anodizing of alloys D16 and Al9 in water solution of sulfuric acid with blowing off an ozone-air mix through a solution are investigated. The intensification of process and increase in thickness, microhardness and wear resistance of covering are established. The technology of anodizing the details of oil-field equipment which has allowed to reduce size of details deterioration while in service in 2 - 8 times is developed.
