DE 10342748 A UPAB: 20050524 NOVELTY - A method for producing a high quality surface finish, e.g. on metals, has a laser pre-treatment to remove pores and inclusions and leaving a surface suitable for conventional mechanical or electrochemical polishing. The laser treatment melts the material to a depth of at most 100 microns using continuous pulse or pulse duration of at least 100 micro seconds. The process is especially suited to metal injection mouldings or fine castings. USE - Pharmaceutical and foodstuff equipment. ADVANTAGE - Produces high quality surfaces on porous materials.
