The microstructure of the FSPed HSSs contains martensitic matrix (α′) with the fine fragmented carbides (M₂C, M₆C, MC and M₇C₃) in stir zone (SZ). Compared to the quenched and tempered (QT) HSSs, FSPed M35 and M42 exhibited higher hardness (883.4 ± 4.9 HV_0.2 and 970.5 ± 3.0 HV_0.2 respectively) at 25 °C due to the increased martensite content and more refined and evenly distributed carbides. As the temperature increases, the hot hardness of both QT and FSPed HSSs decreases. Compared to the QT HSSs, the superior high-temperature wear resistance of the FSPed HSSs is attributed to the hard martensite, refined carbides and high hot hardness. The wear rate of the FSPed HSSs increases with the temperature, reaching its highest at 400 °C due to the softening effect and abrasive wear (as the P–B ratio of most oxides exceeds 2). The wear rate then decreases at 600 °C because of the presence of the thickest oxide glaze on the surface. Additionally, the high-temperature wear resistance the FSPed M35 is greater than that of the FSPed M42, due to the higher hot hardness, more oxides with P–B ratio between 1 and 2 and a thicker oxide layer. Thus, FSP is more effective than the traditional heat treatment in enhancing the hot hardness and high-temperature wear resistance of the HSSs.</div></div>","PeriodicalId":18227,"journal":{"name":"Materials Chemistry and Physics","volume":"348 ","pages":"Article 131603"},"PeriodicalIF":4.7,"publicationDate":"2025-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145227293","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to create and characterize a multi-scale geometric surface on grade 2 titanium samples, simultaneously alloyed with silver, using a hybrid laser/hydrothermal process. The effects of laser parameters on surface morphology, roughness, and wettability were evaluated for both surface-alloyed and unalloyed samples.

Subsequent hydrothermal treatment further modified the surface by forming a nanoscale Ag/sodium titanate structure on the laser-induced micro-roughness, significantly enhancing wetting behavior and resulting in a superhydrophilic surface. Moreover, increasing the laser groove line spacing altered the surface micro/nanostructure morphology, leading to the formation of a silkworm-like titanate structure.

However, in addition to the exfoliation parameters, the obtained graphene quality can strongly depend on the graphite electrode type used for exfoliation, and a proper understanding is lacking. In the current work, the impact of graphite electrode types in graphene exfoliation has been investigated. Three different commercially available graphite types, namely, graphite block, graphite foil (compressed), and synthetic graphite foil types, are explored. Electrolyte solutions of H₂SO₄ combined with KOH of molar concentration of 0.1 M − 3 M are used for the ECE. In the case of the graphite block, despite having an exfoliation rate of ∼10⁻³ g/min, no graphene flake was found. Compressed and synthetic type yields graphene material with a rate of 10⁻³ - 10⁻⁴ g/min, depending on the molar concentration and electrical parameter. Raman study reveals exfoliation from compressed type provides I_D/I_G of 1.06, which seems to decrease to 0.19 (lesser defect) after sonication. On the other hand, for the synthetic type, the I_D/I_G value is 1.36. The microstructural configuration of the electrode is found to play a key role in the exfoliation process, and a correlation between the two is established. The study substantially advances our understanding of the electrochemical exfoliation process of graphene. We have also proposed and demonstrated a synthesis process of graphene and holey graphene in a simultaneous fashion using a single-cell, two-compartment design that can efficiently synthesize both materials in a single step.
