dc.description.abstractThe aim of this project is the development of a mathematical model, which represents the laser texturing process. To that end, firstly, information on the fundamentals of the laser texturing process is gathered. After the analysis of the state-of-the-art of laser texturing processes, the development of a mathematical model representing the phenomena that takes place in the laser texturing process is carried out. Therefore, the methodology followed for such task consists on 3 steps: creating an approximate model, performing experimental testing of the process, and conducting the validation of the model based on the experimental results obtained. The development of the model is based on the PDE module of Matlab and aims to simulate the vaporization phenomenon in localized areas of the surface. The craters created by the model are later reproduced in experimental tests, by employing a laser, which emits nanosecond pulses. For the purpose of validating the laser texturing model, the results obtained in the simulations and the experimental data are compared and a good correlation is obtained: errors below 5 and 0.5 microns regarding the diameter and the depth of the crater, respectively. Consequently, the mathematical model and the followed procedure are validated.; Proiektu honetan laser-testurizazio prozesuaren zenbakizko eredua garatu da. Horretarako, lehendabizi laser-testurizazio prozesuaren informazioa bildu da, ondorengo programazioan errealitatearen hurbilpen egokia simulatu ahal izateko. Aurrez aipatutako fabrikazio-prozesu honen jakintza eskuratu ostean, ekintza berbera irudikatzen duen eredu matematikoa sortzeko beharrizana ikusi da. Horrela, lanaren metodologia hiru pausotan antolatu da: lehenik, laser-testurizazio prozesu baten eredu hurbildu bat sortu da; ondoren, prozesu errealaren saiakuntza esperimentalak egin dira; eta azkenik, lortutako emaitzen arteko alderaketaren bitartez eredua balioztatu da. Ereduaren garapena Matlab-eko PDE moduluaz baliatuz egin da eta pieza bateko gainazaleko puntu zehatzen lurruntzea simulatzeko gaitasuna dauka. Simulatutako ereduan sortzen diren kraterrak, nanosegundoko pultsuak igortzen dituen laser baten bitartez erreproduzitzeko saiakuntzak egiten dira. Laser-testurizazioa simulatzen duen eredua egiaztatu ahal izateko, simulazioetatik lortutako emaitzak saiakuntza esperimentaletan lortutakoekin alderatu dira eta emaitzen artean korrelazio oso ona lortu da: kraterren diametroan eta sakoneran 5 eta 0,5 mikretako erroreak lortuz, hurrenez hurren. Horrela, garatu den eredu matematikoa eta jarraitutako prozedura balioztatuta gelditu dira.
