摘要： A method has been found for centrifugal casting engine cylinders. A mold is charged with molten aluminum alloy and particulate silicon monoxide having an average size of 0.01 mm to 0.04 mm. The mold is rotated at a velocity and period of time to distribute the particulate silicon monoxide on an inner cylinder surface. The mold is allowed to cool until the aluminum alloy solidifies. A casting is demolded characterized in a uniform inner cylinder surface of the particulate silicon monoxide in an amount of 25 volume % and thickness 1 to 5 millimeters. The engine cylinders are distinguished in resistance to wear. Cylinder liners show no appreciable wear for over 100,000 miles of use.
