This study investigates the fretting fatigue behavior of aluminum alloy–steel connections fastened by swage-locking pins through experiments and numerical analysis. It involved fatigue experiments under tension loading, fretting wear and fatigue analyses, followed by fatigue crack initiation prediction. Results show that the contact surface of clamped plates can be divided into the stick, slip, and open zones, with fretting wear occurring within the slip zone of aluminum alloy plate. Fretting fatigue cracks typically initiate within the slip zone near the stick-slip boundary, specifically at wear scars edges. A finite element model was developed to analyze contact status and stress states of test connections, with the friction coefficient at the aluminum alloy-steel interface optimized based on measured stick zone sizes. Results show the fatigue crack initiation of test connections is predominantly influenced by tensile stresses. Consequently, the SWT multiaxial fatigue criterion, combined with the critical plane method, can be used to predict crack initiation. The predicted crack initiation sites, angles, and fatigue strengths closely matched experimental results, with errors below 20 %, 5 %, and 7 %, respectively.</div></div>","PeriodicalId":23238,"journal":{"name":"Tribology International","volume":"209 ","pages":"Article 110711"},"PeriodicalIF":6.1,"publicationDate":"2025-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143807735","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}

N-alloyed MoSe2 coatings (MoSeN), a subset of TMDs, remain largely underexplored, with no research on their frictional performance across various sliding environments. Herein, an in-depth analysis of DC-magnetron sputtered MoSeN coatings is presented, with N content varying from 0 to 42 at%. Investigation of composition, morphological features, crystal structure, mechanical strength and sliding performance are accessed. Our findings revealed that N additions resulted in increased compactness, amorphous structure and hardness of ∼4.6 GPa, and these improvements remained consistent despite compositional variations. The sliding competency was evaluated under six different conditions, revealing promising results in ambient-air and dry-N2 atmospheres at room conditions and 100 °C. At 200 °C, the sliding performance in ambient-air was better than dry-N2. Friction coefficient for N-alloyed coatings was relatively close, ranging between 0.03 and 0.06, except for a dry-N2 environment at 200 °C. Nevertheless, wear rate showed slight variations, with higher values observed in dry-N2 at 100 °C and 200 °C but remained within a specific range of 1–7 × 10−7 mm3/Nm for all other conditions. This study highlights the potential of MoSeN coatings to be scaled for industrial applications, offering a roadmap for reducing the inherent limitations of PVD sputtering.</div></div>","PeriodicalId":23238,"journal":{"name":"Tribology International","volume":"209 ","pages":"Article 110716"},"PeriodicalIF":6.1,"publicationDate":"2025-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143829260","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}

Most importantly, this method of preparing MAO coating on non-valve metal surface does not need any pretreatment or high current density. The results obtained demonstrated that the incorporation of the (NaPO3)6 additive facilitated the direct deposition of MAO coatings on the surface of non-valve metal-T2 copper, with an increase in coating thickness and roughness observed as the (NaPO3)6 content rises. The compositions of the coatings included CuO, Cu2O, α-Al2O3, CuAlO2, Cu(OH)2 and amorphous AlPO4. The content of Cu-containing compounds in the coatings exhibited an initial increase, followed by a subsequent decrease, with the increase of (NaPO3)6 content. The highest percentage (14.39 at%) of elemental Cu was observed when the content of (NaPO3)6 was 10 g/L and it was observed that the coating exhibited the lowest average surface porosity (8.29 %) at this content level, in addition to the highest hardness (890.18 HV) and minimum wear depth (4.78 μm) and average COF (0.161) for a load of 10 N.

In this paper, the normal, tangential loading and friction induced electromechanical responses of Cu/ polydimethylsiloxane (PDMS) interfaces under different geometrical parameters and loading velocities (V) have been studied experimentally and numerically. The polarization model considering flexoelectric effect, interface damage and friction effect is proposed. The results show that tangential loading and voltage U increase with increasing of interface area and V; the first extreme value of U (-200∼+200 mV) are mainly related to flexoelectric effect (strain gradient), the second extreme values of U (60–1100 mV) are affected by interface damage. The normal loading induced U are generated by interface damage. The friction induced U (-200∼-2700 mV) is related to relative friction distance and effective contact area. Theoretical analysis shows that, the flexoelectric coefficients are 10−11∼10−10 C·m−1, the interface damage induced voltage is 4424.63 ± 433.12 V·m−2, the friction induced voltage is 17.54 + 391.43 Lc (V·m−1) (Lc is the compression distance).
