引入使用羟基磷灰石 (HAp) 丸粒的细颗粒喷丸 (FPP)，以形成 HAp 表面层并提高商业纯 (CP) 钛的疲劳性能。使用显微维氏硬度计、光学显微镜、扫描电子显微镜 (SEM)、能量色散 X 射线光谱仪 (EDX)、X 射线衍射仪 (XRD) 和非接触扫描白光干涉仪对 FPP 处理的样品的表面微观结构进行表征。 FPP 可以通过喷射粒子转移在相对较短的时间内（1 秒）在 CP 钛表面形成 HAp 层。此外，FPP提高了表面硬度，并在处理后的表面产生残余压应力。在室温空气中以0.1的应力比进行四点弯曲疲劳试验，以检验使用HAp丸粒的FPP对CP钛疲劳性能的影响。结果发现，经过 FPP 处理的样品的疲劳极限高于未喷丸样品的疲劳极限。从断口分析的角度讨论了经FPP处理的CP钛的疲劳断裂机理。疲劳测试后，HAp 层保留在表面上，没有分层。
Fine particle peening (FPP) using hydroxyapatite (HAp) shot particles was introduced to form the HAp surface layer and improve the fatigue properties of commercially pure (CP) titanium. The surface microstructure of the FPP-treated specimens was characterized using a micro-Vickers hardness tester, optical microscopy, scanning electron microscopy (SEM), energy dispersive X-ray spectrometry (EDX), X-ray diffraction (XRD), and non-contact scanning white light interferometry. FPP could create a HAp layer on the surface of CP titanium within a relatively short time (1 s) by shot particle transfer. In addition, FPP increased the surface hardness and generated compressive residual stress at the treated surface. Four-point bending fatigue tests were performed at a stress ratio of 0.1 in air at room temperature to examine the effect of FPP using HAp shot particles on the fatigue properties of CP titanium. It was found that the fatigue limit for the FPP-treated specimen was higher than that for the unpeened specimen. The fatigue fracture mechanism for the CP titanium treated with FPP was discussed from the viewpoint of fractography. The HAp layer remained on the surface without delamination after the fatigue tests.
