A laser tool for surface treatment of bulk ceramics and ceramic coatings

A laser tool which is reliable, flexible and easily controlled for future process automation has been designed. The device includes a 3 kW carbon dioxide laser, a 3 axes table, power feeder and a fast pyrometer for measuring surface temperatures. The methodology was first to investigate the beam parameters and possible powder flows in single laser scan, to define optimal zones of treatment. The next step was to optimise the best treatments in multi-scanning with overlapped laser tracks to achieve suitable samples for thermo-mechanical testing.
