Chromizing-Diffusion Coatings


Chromized smelt spouts

Chromizing is the diffusion-controlled enrichment of component surfaces with chromium to impart superior levels of corrosion and/or erosion resistance. ATC pioneered the development of the chromium-enhanced studs for use in both the Pulp and Paper and Utility industries. ATC also has chromized larger pressure parts, such as waterwall tubing panels for installation in Recovery and Utility type boilers.
