A program is proposed to generate feasibility information on the possibility of developing a coating system which has the characteristics of being high temperature, wear-resistant, and self-lubricating. The proposed program involves depositing layers of FeCrAlY onto cast iron. A computer system will allow grading the FeCrAlY system into an Atria stabilized Zirconia layer. Finally, several different top coat materials, admixed with a well known, high temperature dry lubricant, will be deposited. Because a very versatile, very economical coating process is required, the plasma spray process has been selected. With only minor amounts of automation and computer control, the process is capable of graduated or abrupt coating changes. Such material coating systems are expected to be critical to the further advancement of diesel engine technology.The potential applications as described by the company: This program will generate feasibility information on the possibility of developing a coating system which has the characteristics of being high temperature, wear-resistant, and self-lubricating. Such coatings will have immediate and also longterm applicability to diesel engines, for the turbo charged systems, and the more advanced adiabatic system.
