English title:	SAMPLE HOLDER FOR X-RAY DIFFRACTION: BRUKER D8 ADVANCE ECO DIFRACTOMETER
Spanish title:	PORTA MUESTRAS PARA DIFRACCI�N DE RAYOS X: DIFRACT�METRO BRUKER D8 ADVANCE ECO.
English abstract:	Through this research, we sought to select and design a version of the already existing sample holders for the Bruker D8 Advance Eco diffractometer belonging to the Pascual Bravo University Institution, which is used to determine structural characteristics of materials. This process seeks, among other things, to reduce the cost of the sample holders since currently the costs associated with the sample holders are high and with designs that greatly limit the possibilities of measuring various samples. Due to the above, a design process was carried out seeking to meet the evidenced needs that the institution has had when analyzing the samples. Therefore, the selection of the most appropriate material was made considering conditions such as: weight, type of samples to be analyzed, behavior before radiation, ease of manufacture and cost. According to the above, the following materials for manufacturing were determined, these had to present an adequate behavior to the exposure of x-rays (radiotransparent and radiolucent) so that at the time of carrying out the tests the sample holder did not interfere with the reading of the material at To analyze, two materials that had this characteristic were chosen, which were PLA and AISI 304 stainless steel. After this, a removable sample holder design was proposed in CAD that allowed us to investigate conditions for the evaluation of the phase as a modification. of the height, the amount of volume, measurement surface, among others. Therefore, with this sample holder it was possible to modify the main geometry of the sample holder base considering the above and depending on whether the sample to be studied was solid (block) or powder. Once the final design was established, it was decided to manufacture the PLA sample holder through additive manufacturing of 3D printing. Diffraction tests for Silicon Oxide (SiO2) and Aluminum Oxide (AlO2) were carried out and the phases were analyzed, verifying the quality of the results. After this, it was possible to show that the results of the diffraction patterns of both Oxides corresponded to those that should be obtained, which was an important result, considering that the sample holder made with PLA has an approximate cost of 1,500 times less than those offered by the manufacturer.
Spanish abstract:	A trav�s de esta investigaci�n se busc� seleccionar y dise�ar una versi�n de los portamuestras ya existentes para el difract�metro Bruker D8 Advance Eco perteneciente a la Instituci�n Universitaria Pascual Bravo, el cual es utilizado para determinar caracter�sticas estructurales de los materiales. Este proceso busca entre otras cosas reducir el costo de los portamuestras dado que en la actualidad los costos asociados a los portamuestras son elevados y con dise�os que limitan en gran medida las posibilidades de medici�n de diversas muestras. Por lo anterior, se tuvo un proceso de dise�o buscando suplir las necesidades evidenciadas que ha tenido la instituci�n a la hora de analizar las muestras. Por ello, se realiz� la selecci�n del material m�s adecuado considerando condiciones como: peso, tipo de muestras que se van a analizar, comportamiento ante la radiaci�n, facilidad de fabricaci�n y costo. Seg�n lo expuesto anteriormente, se determinaron los siguientes materiales para la fabricaci�n, estos deb�an presentar un comportamiento adecuado a la exposici�n de rayos x (radiotransparentes y radiolucentes) para que al momento de realizar las pruebas el portamuestras no nos interfiriera en la lectura del material a analizar, se eligieron dos materiales que contaban con dicha caracter�stica, los cuales fueron el PLA y acero inoxidable AISI 304. Posterior a esto, se plante� un dise�o de porta muestras desmontable en CAD que nos permiti� investigar condiciones para la evaluaci�n de la fase como modificaci�n de la altura, la cantidad de volumen, superficie de medici�n, entre otros. Por ello con este portamuestras fue posible modificar la geometr�a principal de la base del portamuestras considerando lo anterior y dependiendo si la muestra a estudiar era s�lida (bloque) o en polvo. Una vez establecido el dise�o final se decidi� fabricar el porta muestras de PLA mediante manufactura aditiva de impresi�n 3D. Fueron realizados ensayos de difracci�n para oxido de Silicio (SiO2) y �xido de Aluminio (AlO2) y se analizaron las fases constatando la calidad de los resultados. Posterior a esto, se pudo evidenciar que los resultados de los patrones de difracci�n de ambos �xidos correspond�an a los que deb�an que ser obtenidos, lo cual fue un resultado importante, considerando que el portamuestras fabricado con PLA tiene un costo aproximado de 1.500 veces menor que los ofrecidos por el fabricante.
