Research on precise laser drilling in ceramic materials = Investigación sobre perforación precisa por láser en materiales cerámicos

Abstract

[ES] El trabajo está relacionado con la Microfabricación con láser 3D, y el objetivo del mismo consiste en llevar a cabo ensayos en el laboratorio con un láser verde hasta conseguir realizar pequeñas perforaciones(agujeros) sobre piezas de materiales cerámicos. Primero se llevará a cabo un trabajo de investigación de los antecedentes, tipos de láser, ventajas y desventajas de la perforación con láser, materiales cerámicos, actualidad... Y después se realizaran una serie de ensayos en el laboratorio con distintos materiales y variando la frecuencia del láser hasta lograr nuestro objetivo, que consiste en realizar pequeños agujeros. Por último se presentaran los resultados obtenidos y se hará un estudio minucioso de los mismos.

[EN] So that his project has been divided into two parts: a theoretical part and a practical part. The theoretical part, is the most extensive and is necessary to know the background of the laser beam. In this part a research of information was made in different sources on the types of lasers, physical processes occurring during the laser beam interactions with materials and how affect these processes to the differents parameters, the different methods of manufacturing with lasers like laser drilling, laser cutting, laser welding... And the last point of this part that is the laser drilling of ceramic materials. In the practical part a series of tests were carried out in the laboratory, which consisted of drilling several holes in a ceramic piece with the laser beam and later analyzing the results. This project is a study on laser drilling in ceramics materials. The objective of the work is to make small holes in a ceramic piece and analyze how they affect the different parameters of the laser beam to them.
