Resumen:
The application of an hybrid organic-inorganic sol gel made coating could be done by several techniques. For replacing the typical dipping deposition method and to help to cover non geometric large surfaces, the spray technique could be used. The spray or pulverization technique demands the optimization of several variables like gun tip openness, sol pressure, carrier, distance to the substrate target, etc., so it is of great importance to have tools to analyze the spray perfor-mance of the deposited substance on the target. The optimiza-tion of the cover power of the gun shot, image processing tech-niques, in particular Fuzzy Mathematical Morphology (FMM) is presented as an efficient tool. In this paper we propose to apply FMM techniques to solve to estimate the cover area of a coated surface by spray technique, measuring the profile depo-sition area from the completely cover surface (center of the spry ace gun), to the edge of the spray cone. From analyzing the cover fraction of the spray from the center to out the shot, some important data can be obtained to make multiple spray deposition in complex surfaces geometries.
