CASTING PART FOR INTERNAL COMBUSTION ENGINE WITH CASTED REINFORCING BODY AND METHOD OF FORMING COUPLING SECTION BETWEEN SAID CASTING PART PROPER AND REINFORCING BODY

摘要

Light alloy components for internal combustion engines consist of castings in which reinforcing layers consisting of non-woven ceramic fibers are embedded in the stressed surface portions. In order to provide a prolonged protection against damage to the light alloy disposed under the reinforcing layer, the open interstices of the fibrous layer are impregnated with a layer of a ceramic material in the portion which is close to the stressed surface and with the light alloy of the component in the portion which is remote from the stressed surface.
