| Cur Síos: | This research shows a study of particles present in 304 stainless steel used in the assembly of medical devices. The study was performed in order to develop a superficial, chemical and thermal characterization, which allows to know the nature of the impurities. A complementary analysis using different techniques such as Scanning Electron Microscopy (SEM), Energy Dispersive Spectroscopy (EDS), Thermogravimetric Analysis (TGA), Differential Scanning Calorimetry (DSC), and X-Ray Diffraction Analysis (XRD) was used to characterize the particles, and to conclude on their origin and possible treatment. The best results for the analysis were obtained from the images generated in the SEM, since the nature of the impurity was superficial, so it was possible to recommend as a cleaning method the use of organic solvents. |
