The feasibility of obtaining bioactive coatings on Ti6Al4V alloy by laser deposition was studied. A Nd:YAG source was used under the following parameters: 65 or 70% of average power, 8 ms of pulse duration, 8 Hz of frequency and 0.7 mm/s of travel speed. A CaO-SiO₂ powder mixture, with a molar ratio of 1:1, was projected to the metallic surface during the laser treatment. Due to the heat supplied by the laser, pseudowollastonite was the main compound formed in situ on the Ti6Al4V alloy samples as a result of the chemical interaction among calcium and silicon oxides and titanium from the alloy. A higher quantity of pseudowollastonite was formed on the sample treated at the highest average power used (70%). In vitro bioactivity assessment was performed by immersing pulsed laser-treated samples in a simulated body fluid (SBF) for 21 days. A dense Ca, P-rich layer was formed on the samples. The spherical morphology of the agglomerates formed is similar to the apatite formed on the existing bioactive systems.

研究了通过激光沉积在Ti6Al4V合金上获得生物活性涂层的可行性。在以下参数下使用Nd：YAG源：平均功率的65％或70％，脉冲持续时间8 ms，频率8 Hz和行进速度0.7 mm / s。在激光处理期间，将摩尔比为1：1的CaO-SiO ₂粉末混合物投射到金属表面。由于激光提供的热量，假硅灰石是在Ti6Al4V合金样品上原位形成的主要化合物，这是由于合金中钙和氧化硅与钛之间的化学相互作用所致。在使用的最高平均功率（70％）下处理的样品上形成了更高数量的假硅灰石。体外通过将脉冲激光处理过的样品浸入模拟体液（SBF）中21天来进行生物活性评估。在样品上形成致密的富含Ca，P的层。形成的附聚物的球形形态类似于在现有生物活性体系上形成的磷灰石。
