Fabrication of Cr-Cr23C6/Cr2N Composite Coatings: Change in the Phase Structure and Effect on the Corrosion Properties

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 resu...

Description
Summary: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.
