Abstract
A hypereutectic aluminum-silicon alloy cylinder bore liner is produced by feeding the molten alloy into a metal mold having an inner shell sand cup, while rotating the mold at a speed in excess of 1,000 rpm, to cause the molten alloy to be thrown outwardly by centrifugal force to form a cylindrical liner. On solidification of the alloy, discrete silicon particles are precipitated and the use of the sand shell increases the fluid life of the alloy to enable the lighter weight silicon particles to migrate inwardly under the centrifugal force of rotation, to produce a solidified liner having a greater volume fraction of silicon particles in the inner portion of the liner where greater wear resistance is desired.
