Application of a laser cladding process to valve seats; (first report) - development of the production engineering

摘要

We have developed an optical system and casting materials for a laser cladding process and applied a laser-clad layer to the valve seats of an engine cylinder head. The engine to which this technology was applied provides the same level of durability as a conventional engine and improved performance. Production facilities have also been developed that feature centralized control of the process conditions, including the powder supply quantity, laser output and their respective timing.
