This study investigates the gradient microstructure evolution and resultant surface integrity in TC18 alloy induced by two advanced cold machining techniques—abrasive waterjet machining (AWJM) and waterjet-guided laser (WJGL) machining. AWJM produces a deformation-dominated structure, reducing the α-Ti and β-Ti grain sizes by 71 % and 85 %, respectively, and increasing the fraction of low-angle grain boundaries (LAGBs) to 48.6 %. This enhancement increases surface hardness by 12 % through grain refinement. In contrast, WJGL machining generates a thermally-driven gradient, retaining 37.73 % metastable β-Ti phase at the surface and dominated by high-angle grain boundaries (HAGBs, 91.3 %), which improves hardness by 7 % through rapid cooling. Oxidation analysis reveals that AWJM promotes the formation of high-valent TiO₂ (66.67 %), associated with compressive residual stresses that are beneficial for fatigue and wear resistance. In contrast, WJGL machining favours the formation of lower-valent Ti₂O₃ (56.31 %), which influences surface reactivity and lubricant retention. The study establishes that AWJM is suitable for applications requiring deep gradient reinforcement and superior wear resistance, while WJGL machining is ideal for precision components that demand an excellent surface finish and controlled friction under light loading. These findings provide a foundational guideline for selecting machining processes to tailor surface integrity and tribological performance in high-performance titanium alloys.</div></div>","PeriodicalId":23238,"journal":{"name":"Tribology International","volume":"218 ","pages":"Article 111697"},"PeriodicalIF":6.1,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146038929","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, due to the intricate interface contact dynamics during meshing, it is necessary to elucidate the influence of hard-phase distribution parameters on fatigue damage progression and contact stress redistribution. Therefore, an equivalent rolling disk was employed to investigate the influence of hardened unit distribution patterns on rolling contact fatigue (RCF) behavior at the pitch circle position through coupled experimental and finite element analysis. The result showed that the rolling contact wear volumes were reduced by 41.9 % and 55.4 % for the \"large-sparse\" and \"small-dense\" hardened unit distributions, respectively, compared to the untreated samples, which significantly enhanced the contact fatigue wear resistance of the cylindrical surfaces. It was also observed that the hardened units exerted a distinct spatial blocking effect on interfacial plastic flow, with the plastic flow layer depths being reduced by over 60 % and 83 % for the two configurations, respectively. The originally uniform contact stress distribution was discretized, leading to the formation of localized stress concentrations within the hardened unit regions while the contact stress in the soft matrix was reduced, inducing a periodically fluctuating and locally concentrated contact stress field.

Micro‑arc oxidation (MAO) of Ti6Al4V for femoral stems offers a practical and promising approach to mitigating this problem. However, the fretting wear behavior between MAO‑Ti6Al4V and femoral head materials remains unclear. In this study, a high‑quality ceramic coating was first fabricated on Ti6Al4V by MAO. Fretting wear tests were then conducted under conditions representative of service environments of taper junctions in artificial hip joints. The fretting wear behavior and mechanisms of MAO‑Ti6Al4V/ZTA and MAO‑Ti6Al4V/CoCrMo pairs, as well as the respective contributions of the substrate and counterbody to material loss, were systematically investigated. The results demonstrated that, for both pairs, MAO treatment significantly reduced the fretting friction coefficient and wear rate of Ti6Al4V alloy, thereby providing effective protection and indicating considerable potential for clinical application in taper junctions. Moreover, the MAO‑Ti6Al4V/CoCrMo pair exhibited three‑body wear and a more pronounced micro‑cutting effect under the gross slip regime (GSR) and mixed fretting regime (MFR), which led to greater material loss and induced fatigue damage. In contrast, the MAO‑Ti6Al4V/ZTA pair was associated with lower fretting damage and superior fretting wear resistance. Notably, in the MAO‑Ti6Al4V/CoCrMo pair, the majority of material loss originated from CoCrMo, whereas in the MAO‑Ti6Al4V/ZTA pair, material loss occurred predominantly in MAO‑Ti6Al4V.
