Chromium-Free Corrosion Solutions

摘要

The advantages offered by the ceramic system has provided solutions in the trucking and automotive industries. The deformation tolerance of the system has allowed end users to use steel instead of stainless steel, avoiding additional cost, pitting and cracking, and galvanic corrosion problems associated with stainless steel. Using a chrome-free system also offers the advantage of eliminating environmental concerns of both hexavalent and triva-lent chromium passivate systems while protecting a manufacturer from costly false-positives when testing for hexavalent chromium in the European Union.rnAs chromium-free alternatives are sought, high-performance solutions can be obtained using a thin ceramic coating. The Elisha EMC system is a commercially available system that offers advantages over trivalent chromium passivate at a cost-competitive price.
