Abstract

In this work was explored the removal possibility of strippers by acid, alkaline and organic bases, was explored the corrosion effect of strippers for typical metal materials for aircrafts the aluminium alloys 1163-T, B95-T2, the steel 30HGSA. The fact of the corrosive effect of strippers for metal materials was experimentally substantiated. The negative impact of the several strippers (in the case of their mixing) for the surface of the fragments of the aluminum alloy cladding, and, accordingly, on the resource characteristics (low-cycle fatigue), is studied, using the example of the B95-T2 alloy.
