Abstract
An improved multi-layer gasket comprises only three metal plates and incorporates a dual coating system with different coatings applied to specific layers of the gasket. Through the orientation of the layers, a high temperature coating is used to enhance a combustion gas seal while an elastomer seal coating enhances a fluid seal. Through the selection of base metal thicknesses and coating thicknesses, an increased thickness area can be achieved to obtain an optimum load balance between the combustion seal and the fluid seal.
