Validation of Computational Modeling of Spray Parameters as a Tool to Optimize Fine Particle Size WC-NiCr HVOF Coatings Available to Purchase

Optimized high-velocity oxy-fuel spraying of fine-cut WC-NiCr powder results in dense, crack-free, and ductile coatings, with a smoother as-sprayed surface that is expected to reduce grinding efforts and enhance coating performance. These coatings are candidates for replacing hexavalent chromium plating in high-performance applications.
