    • Abstract:
      This technical report presents the first stage results of a multi-year project to develop chromate-free paints and corrosion protection systems. Chromate coatings and chromate-containing paints are very effective in providing corrosion resistance and are widely used in the manufacturing, transportation and defense industries; however, there is a need to find an environmentally- and occupationally-friendly replacement to chromate (chromium VI is considered a carcinogen with an extremely low personal exposure limit). The tasks of this first stage consisted of the scale-up and corrosion testing of an alternate-to-chromate coating, initiation of biocorrosion tests, and development and corrosion testing of a wash primer. The alternate-to-chromate coating involves substituting titanium for chromium (titanium is much safer than chromium and it is used for hip replacement in humans). The new formulation protects in the same manner as chromate and has been able to match the test data for chromated surfaces. Microbially-influenced corrosion (biocorrosion) studies were initiated by establishing marine bacteria cultures and conducting preliminary electrochemical impedance spectroscopy measurements. A wash primer containing polyaniline (an electroactive polymer) instead of chromate was also developed and corrosion tested. The report ends with a summary of future tasks to further develop chromate-free paints and anti-corrosion systems. References, appendix, 11 figures, 1 table; 18 p. (567 kb)
