Field tests of chromate-free conversion coatings on 1105 aluminum alloy for different climatic zones
Abstract
Lately, more attention has been paid to the recycling of materials and the use of secondary products in final products. This also applies to metals, including aluminum and its alloys. One of the aluminum alloys made from recycled metal is 1105alloy. It has low corrosion resistance; therefore it is used in cold, dry climates, at zero and negative temperatures. In this work, modern inhibited IFKhANAL conversion coatings to protect 1105 alloy were studied. They should allow to be used this alloy in different climatic zones. For this, electrochemical studies and field tests of coatings in an urban industrial atmosphere and in a tropical climate were carried out. It is shown that coatings can protect 1105 alloy up to 1 year and when using acrylate pain system – more than 1 year.
