| description | In this work, the effect of the modification by laser ablation of hydroxyapatite surfaces synthesized by sol-gel on the capacity of apatite formation by in vitro tests was analyzed. For this, layers of sodium titanate were grown on disks of the Ti6Al4V alloy by immersion in 10 M NaOH at 60 ° C for 24 hours. The hydroxyapatite coatings were then prepared using calcium nitrate tetrahydrate and triethyl phosphite as precursors by the sol-gel method and the dip-coating technique. Finally, patterning was performed by means of an Nd: YAG laser, with working energy of 1.3 mJ. Hydroxyapatite was evaluated and characterized using X-Ray Diffraction, Scanning Electron Microscopy and Dispersive X-ray Energy Spectroscopy techniques. In order to evaluate the reactivity, immersion in simulated body fluid was carried out and calcium atomic absorption analysis was carried out to observe the dissolution and precipitation phenomena of this ion, and it was determined that the samples treated at 600 ° C They induced a better response to the growth of apatites, however, all the coatings have characteristics that would allow these coatings to be used as implants in bone substitutes. |

En este trabajo se analizó el efecto que tiene la modificación por ablación laser de superficies de hidroxiapatita sintetizados por sol gel en la capacidad de formación de apatitas mediante ensayos in vitro. Para ello se crecieron capas de titanato de sodio sobre discos de la aleación de Ti6Al4V mediante inmersión en NaOH 10 M a 60ºC durante 24 horas. Luego se prepararon los recubrimientos de hidroxiapatita utilizando como precursores el nitrato de calcio tetrahidratado y el trietil fosfito por el método sol-gel y la técnica dip-coating. Finalmente se realizó un patronamiento por medio de un láser Nd: YAG, con una energía de trabajo de 1.3 mJ. La hidroxiapatita se evaluó y caracterizó empleando las técnicas de Difracción de Rayos X, Microscopía Electrónica de Barrido y Espectroscopía de Energía Dispersiva de rayos x. Con el fin de evaluar la reactividad de las superficies se realizó una inmersión en fluido corporal simulado y se llevó a cabo análisis de absorción atómica de calcio, para observar los fenómenos de disolución y precipitación de este ion, y se determinó que las muestras tratadas a 600°C indujeron una mejor respuesta al crecimiento de apatitas, sin embargo, todos los recubrimientos presentan características que permitirían que estos recubrimientos sean usados como implantes en sustitutos óseos.
