A method of imparting high-temperature, degradation resistance to a component associated with an internal combustion engine involving applying a metal slurry comprising a Co-based metallic composition, a binder, and a solvent to a surface of the component, and sintering the Co-based metallic composition to form a substantially continuous Co-based alloy coating on the surface of the body. An internal combustion engine component comprising a metallic substrate and a Co-based metallic coating thereon which has a thickness between about 100 and about 1000 microns.
L'invention concerne un procédé pour conférer une résistance à la dégradation à haute température à un composant associé à un moteur à combustion interne, consistant à appliquer une pâte de métal comprenant une composition métallique à base de Co, un liant et un solvant sur une surface du composant et à fritter la composition métallique à base de Co afin de former un revêtement en alliage à base de Co sensiblement continu sur la surface du corps. L'invention concerne également un composant pour moteur à combustion interne comprenant un substrat métallique et un revêtement métallique à base de Co déposé dessus qui présente une épaisseur comprise entre environ 100 et environ 1000 microns.
