Abstract
A flat metal sealing gasket is made as follows: on an unhardened spring steel plate having an aperture and a bead surrounding the aperture, a sinterable powder is deposited along the bead in a desired shape and thickness. Thereafter a sufficiently high temperature is applied to the deposited sinterable powder to effect sintering or melting of the powder to provide a pressure-resistant overlay on the plate and to simultaneously effect a hardening of the plate.
