LASER TREATING OF CYLINDER LINERS FOR DIESEL ENGINES TO INCREASE WEAR RESISTANCE

A multi-Kilowatt laser is now in use by the Electro-Motive Division of General Motors to achieve harder, more scuff-resistant cylinder liners in high-performance turbocharged diesel engines. The carbon dioxide laser beam system allows hardening to sufficient depth without heating the entire piece and thus precise dimensions of the liner structure can be maintained. To prevent the beam from boring through the metal and to provide uniform heating, the beam is kept moving across the metal surface. This is accomplished by rotating the metal piece continuously.
