En este estudio se obtuvo recubrimientos de fosfatos de calcio sobre sustratos de Ti6Al4V ELI ASTM F-136, los cuales fueron previamente tratados a partir de una mezcla de ácidos HCl: H2SO4: H2O (1:1:1), con el fin de obtener una mayor rugosidad y así mejorar la adherencia del depósito. Las variables estudiadas fueron agitación (600 y 800 rpm), temperatura (25 y 60°C) y voltaje (-9 y -15 V). Los depósitos obtenidos se caracterizaron por SEM-EDS y TF-IR. se pudo concluir que a temperatura ambiente no hay precipitación de fosfatos, y a 60°C se obtuvieron relaciones Ca/P entre 1.35 y 2.3.
In this study calcium phosphate coatings was deposited on substrates of Ti6Al4V ELI ASTM F-136, which previously were treated from acid mixture HCl:
H2SO4: H2O (1: 1: 1), with the purpose of obtaining a greater roughness and to improve the adhesion of the deposit. The variables studied were agitation (600 and 800 rpm), temperature (25 and 60°C) and voltage (- 9 and -15 V). The deposits obtained were characterized by SEM-EDS and TF-IR, it was possible to be concluded that is not phosphate precipitation at room temperature, and at 60°C the relations Ca/P were between 1,35 and 2.3.
