Abstract
The aim of the study is to investigate the effectiveness of protective coatings: hot galvanizing, metallization aluminum and combined metal polymer: metallization aluminum with epoxy coating for possible protection against hydrogen sulfide corrosion.
To determine the possibility of protection steels from hydrogen sulfide corrosion and corrosion cracking, zinc coatings, applied with hot dip galvanizing, metallized aluminum coatings, applied by electro-arc spraying and combined metallization aluminum + epoxy in media of different aggressiveness were investigated. It is shown that the application of zinc coating on 20 steel increases the corrosion resistance on average in 1.5 times in model sea water (MSW) without hydrogen sulfide and almost in 2 times in the MSW saturated with hydrogen sulfide compared with that for non-coated 20 steel. In the NACE solution, the corrosion resistance of samples with zinc coating is sharply reduced, which indicates the inexpediency of the use of such coatings in acidic environments. Examples of aluminum coatings showed high corrosion resistance in MSW with different content of hydrogen sulfide and in NACE solution: the corrosion rate of steel with aluminum coating is reduced in ~7.3 times in the MSW saturated with hydrogen sulfide and in ~1.7 times in NACE solution compared to the corrosion rate of steel without coating.
Investigation of the susceptibility to stress corrosion cracking showed that samples with an aluminum coating showed higher resistance to hydrogen sulfide stress corrosion cracking than samples without coating. And samples with a combined coating (metallic aluminum + Jotamastic 87GF) showed better protective properties than samples with aluminum coating. Aluminum coatings applied by the method of electric arc spraying on 20 steel and combined coatings can be recommended for the protection of metal surfaces in hydrogen sulfide media of different aggressiveness.
