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.

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 FE-CR-AL-Y ONTO CAST IRON. A COMPUTER SYSTEM WILL ALLOW GRADING THE FE-CR-AL-Y SYSTEM INTO A YTTRIA STABALIZED 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 GRADATED OR ABRUPT COATING CHANGES. SUCH MATERIALING SYSTEMS ARE EXPECTED TO BE CRITICAL TO THE FURTHER ADVANCEMENT OF DIESEL ENGINE TECHNOLOGY.
