【 摘 要 】

The influence of tool effects of the processing media on formation of corrosion characteristics (reactive capacity and corrosion resistance) in the surface layer of aluminum alloys during strengthening by surface plastic deformation and vacuum ion-plasma processing has been investigated. It has been shown, by example of V95pchT2 alloy, that formation of the surface layer corrosion characteristics under the integrated effect of processing media (shot, plasma) is determined by the interaction modes of the tool/work surface contact pair. The influence of reactive capacity, which has been formed during strengthening, on changing corrosion resistance of the strengthened surface layer under the action of 5 % solution of NaCl (120 hours test base) has been considered.
