Abstract

Laser surface melting treatment was achieved by a 2 Kw CO2 surgical laser system.The partially defocused laser beam provided a circular spot with an annular energy distribution on the sample.

It is certain that laser surface treatment will do the job of repairing in defective ceramic tiles. All glazes provided by American Standard were tested for an ability of withstand laser treatment when coated on to a glazed tile. In order to repair the defective ceramic tile it is necessary to patch the damaged region with a cement. The cement must then be glazed in order to match that of the undamaged portion of the ceramic tile. I worked on the exact process parameters under which this glazing should take place. I also zeroed on the exact requirement of materials for a perfect color match with the base material. The experiments have been conducted keeping in mind the ease of industrial implementation.
