The paper will present the methodology used to design optimized die coatings employed inmaterial forming processes in an effort to extend the life and effect efficient operation of the dies. Anoptimized die coating 'architecture' requires that the coating system be essentially non-wetting withthe material (metal, glass, polymer) being formed in the die, coupled with good wear and oxidationresistance Other factors, such as delaying the onset of thermal fatigue cracking (heat checking), andan acceptably low coefficient of friction. And, possibly, self-lubricating, also need to be consideredbased on the processing and forming conditions that include both liquid and solid materials. Manydifferent die coatings have and are being used with different levels of success. This paper presents thecurrent understanding that has been gained in laboratory testing, in-plant trials, and modeling in aneffort to generate a fundamental understanding of how such optimized die coating systems may bedesigned for specific forming operations and conditions, with examples based on dies used inaluminum pressure die casting, glass molding, and metal forming operations
