CAST IRON CYLINDER LINER WITH LASER-HARDENED FLANGE FILLET

A cast iron cylinder liner for an engine has a body with a radial upper flange and a generally cylindrical wall extending axially from an inner portion of the flange. An arcuate fillet is formed at a juncture between the upper flange and an exterior of the cylindrical wall. To strengthen the junctur...

Zusammenfassung:	A cast iron cylinder liner for an engine has a body with a radial upper flange and a generally cylindrical wall extending axially from an inner portion of the flange. An arcuate fillet is formed at a juncture between the upper flange and an exterior of the cylindrical wall. To strengthen the juncture of thin wall liners, for example with wall thickness less than 2.5 mm, a portion adjacent the fillet is laser hardened to a selected depth of the wall, thus increasing resistance to stresses created in the wall when the liner is installed and operating in an engine.
