Trivalent Chromium Process Capability Study for OEMs

In light of continuing regulations on hexavalent chromium, OEMs have expressed interest in the performance comparison of trivalent chromium to exterior automotive hexavalent chromium. This webinar will review the characteristics of trivalent chromium that impact corrosion resistance, evaluate test matrix variables such as chrome thickness levels and STEP values and present performance results of exterior corrosion testing between trivalent and hexavalent. OEMs and Tier Suppliers, engineers, quality control and plating shop owners will benefit from this presentation. As examined in the recent USCAR field test report, a review of the color stability and high-chloride corrosion performance advantages of chloride-based trivalent chromium chemistries over sulfate will also be presented.

Primary Topics:

  • Origin of Test Matrix and OEM Requested Variables
  • Performance Evaluation of various Trivalent Chrome thicknesses
  • Nickel Plating STEP Value Influence on Corrosion
  • In-depth look at CASS and Russian Mud testing results and comparison
  • Summary of Recent USCAR field test results
