Corrosion protection of magnesium alloys polysulphide sealants

Abstract

Studied the protective properties of polysulfide sealants UT-32NT and VITEF-1NT on the samples of magnesian alloy MA8 after exposure to the tropical chamber during for 7 months, salt spray chamber during for 2 months, andML5 after fuel TS-1. It was found that, when working in an environment of air and tropical climate sealants VITEF-1NT or UT-32NT (film thickness of 1,5–2 mm) are suitable for protecting alloy MA8 oxidized as a sheet and in contact with the rivets on KFО-30 ground or sealant. Sealants VITEF-1NT or UT-32NT after exposure in the fuel TS-1, containing water in the form of a separate phase, have weak adhesion to a magnesian alloy of ML5 oxidized and do not protect it from corrosion.

Keywords
