Cerablak™ protective coatings for non-ferrous molten metal processing

Protective coatings are essential in processing of molten non-ferrous metals to prevent attack on dies, molds, transfer/degassing tubes, ladles, thermocouple protection tubes, and other accessories. Both metal and ceramic components are used for processing molten metal. Corrosion by molten aluminum costs metal manufacturers millions of dollars annually and generates waste products including scrap from casting defects. Significant reduction in operational costs and environmental benefits can be realized with durable and effective coatings. In addition to coating material requirements of durability and non-wetting, the process of deposition needs to be versatile, low-cost, easy-to-apply and cure, and should be environmentally-friendly. Cerablak™ coatings have been proven to show excellent non-wetting properties and corrosion protection against molten aluminum. Coatings were applied to full-size prototypes and tested in both simulated and production environments.
