Abstract

Cr-C composite coatings were electro-codeposited in sulfuric acid-based solutions containing submicrometer-sized carbon black particles. The effect of heat-treatment conditions on the carbide phase formation in the composite coatings and their corrosion behaviors were investigated. The obtained results showed that the Cr-C composite coatings can be fabricated successfully and with an additional heat treatment, it is possible to obtain a Cr-Cr₂₃C₆/Cr₂N composite structure. Therefore, the increase in corrosion potential suggests improvement in corrosion resistance due to the formation of Cr₂₃C₆/Cr₂N. This implies that Cr-Cr₂₃C₆ and/or Cr₂N composite coatings have potential application to industrial fields in many respects.
