Figure 2- SEM micro images at 10.000 × magnifications of the surface technological groups after treatment on the titanium implants of groups C (a); MN (b), MNSr (c), and MNSr+ (d). Below is Sr mapping by EDS (i; j). e–h show laser scanning confocal microscopy 3D reconstruction images of surface groups. Moreover, e–h shows a representative area of 128 µm × 128 µm, identifying peaks and valleys with at least 200 nm of resolution in height. It is possible to verify the moderately rougher groups MN, MNSr, and MNSr+ compared to the machined conditions

图2 - 钛植入物表面处理后各工艺组在10000倍放大下的扫描电子显微镜（SEM）显微图像：C组(a)、MN组(b)、MNSr组(c)及MNSr+组(d)。下方为通过能量色散光谱（EDS）获得的Sr元素分布图(i; j)。e–h为各表面组的激光扫描共聚焦显微镜三维重建图像。此外，e–h展示了128 µm × 128 µm的代表性区域，可识别高度分辨率至少为200 nm的峰谷结构。与机械加工组相比，MN、MNSr及MNSr+组的表面粗糙度呈中度增加，这一现象可得到验证。
