Bewehrungsmaterial für Kolben von Verbrennungsmotoren

摘要

Austenitic cast iron with mainly vermicular and/or nodular graphite is useful as a reinforcing material intermetallically bound to the aluminium base material of the pistons of an internal combustion engine. This material provides improved binding solidity with the adjacent aluminium base material of which the piston is made. The reinforcing material can be composed of different layers.
