Abstract

The influence of surface preparation on performance of alkyd coatings on steel was investigated. Degreas-ing, abrasion with emery, acid pickling, hydroblasting and wet abrasive blasting methods were usedto modify the surface of steel before painting. Steel surfaces were analytically and morphologicallycharacterized before painting. DC resistance and pull-off adhesion methods were used to evaluate theperformance of alkyd coatings on differently prepared surfaces. Results implied the key role of oxidelayer in maintaining the high level of corrosion protection. Also the detrimental influence of the inherentcontamination caused by wet abrasive blasting method was shown as a cause of early failure of protec-tive properties. Comparison between electrochemical and adhesion results showed that they may notindicate towards similar directions in terms of protective properties which is due to the different factorsaffecting them.
