Abstract Attempts to improve the osteointegration, fixation and stability of Ti-base implants have been focused by producing a significative surface roughness that enhances the surface area available for bone/ implant apposition. In this research study, it shows the experimental data by synchrotron radiation X-ray diffraction (SR-XRD) of the main material surface properties (residual stress and cold work) that changed significantly during the application of different surface treatments such as grit blasting and laser shock peening in a biometallic Ti–6Al–4V alloy. The ratio of residual stress to cold work is primarily determined by the material and the specific surface treatment applied. In order to establish how they alter the recorded magnetic signatures and to validate that the residual stress and cold work effects govern the outcome of the magnetic measurements, we used a nondestructive magnetic method. It was displayed that the magnetic method provides the unique capability of nondestructively sensing the thermomechanical relaxation below the treated surface only calculating the normal and tangential magnetic intensities induced by thermocurrents using a fluxgate magnetometer .

摘要 改善钛基植入物的骨整合、固定和稳定性的尝试集中在产生显着的表面粗糙度，增加可用于骨/植入物贴合的表面积。在这项研究中，通过同步辐射 X 射线衍射 (SR-XRD) 显示了主要材料表面特性（残余应力和冷加工）的实验数据，这些特性在应用不同的表面处理（如喷砂和喷砂处理）过程中发生了显着变化。生物金属 Ti-6Al-4V 合金中的激光冲击强化。残余应力与冷加工之比主要由材料和所应用的特定表面处理决定。为了确定它们如何改变记录的磁特征并验证残余应力和冷加工效应决定了磁测量的结果，我们使用了一种无损磁法。结果表明，磁性方法提供了独特的能力，可以无损地检测处理表面下方的热机械弛豫，只需使用磁通门磁力计计算由热电流感应的法向和切向磁强度。
