NDI Through HVOF Coatings

Abstract

Background: HCAT is evaluating alternatives to chrome Environmental issues drive chrome replacement HVOF may replace EHC on military landing gear MLSA evaluated NDI impact Part of the HVOF family MLSA is looking at Detection of cracks under coatings Chrome -- limitations well understood HVOF -- limitations to be determined. Purpose: Assess the detectability of fatigue cracks in a steel component which has been coated with HVOF Compare the results to chrome-plated specimens Determine which NDI methods work Rough estimate of detection limits for EHC and HVOF coatings for this study's specimen geometry.
