ClearTribo–Driven Evolution of Specific Nano–heterostructures to Achieve Exceptional Wear Resistance in Composites
Researchers developed a NiAlTa/cBN composite via spark plasma sintering and investigated how tribological stress and temperature induce specific nano-heterostructures that control wear resistance. At room temperature, an amorphous tribo-layer formed through plastic deformation and oxidation produced an extremely low wear rate (10-7 mm3/N/m) and a friction coefficient of 0.252, while at high temperatures, nanocrystalline subsurface layers and FCC-to-HCP phase transitions altered wear mechanisms, demonstrating that tribo-induced structural evolution is key to exceptional composite wear performance.
Modification of Frictional Surfaces of Bearings by Addition of Nanoparticle Compositions to Lubricants
Researchers studied the effects of nanoparticle additive compositions in lubricating oils on changes to the frictional surface structure and tribological characteristics of a steel-to-steel friction pair, using scanning electron microscopy to analyze surfaces after step-loading fatigue tests.
Dynamic Processes of Substructural Rearrangement under Friction of Carbon Steel
This study examined how heat treatment affects the friction and wear properties of medium carbon steel, linking material microstructure to tribological performance. The research is focused on materials engineering with limited direct relevance to microplastic pollution or human health.
On the Formation and Characterization of Nanoplastics During Surface Wear Processes
Researchers characterized nanoplastic particle generation during surface wear processes, finding that mechanical abrasion of bulk plastic materials produces a broad size distribution of particles including sub-100 nm fragments, with surface wear rate depending on polymer hardness and contact conditions.
In Situ Synthesis and Wide-Temperature Tribological Properties of Biphasic Structure High-Entropy (Mg1/6Ni1/6Co1/6Cu1/6Zn1/6Al1/6)3O4 Ceramics
Researchers developed biphasic high-entropy oxide ceramics with a rock-salt/spinel structure via in-situ synthesis of alumina as a secondary phase, achieving Vickers hardness of 802 Hv and an ultralow coefficient of friction of 0.07 with minimal wear rate at 300°C. The biphasic strategy overcame the mechanical-tribological optimisation bottleneck of single-phase high-entropy oxide ceramics, demonstrating potential for wide-temperature lubricant material applications.
Vastness of Tribology and its Contribution for a Sustainable Development
This review organises the multidisciplinary field of tribology into six branches covering fundamental tribology, materials and lubricants, micro and nanotribology, industrial tribology, biotribology, and emerging frontiers, and examines its contributions to friction and wear reduction for sustainable development.
Microstructural and Mechanical Properties of Al2O3 and Al2O3/TiB2 Ceramics Consolidated by Plasma Pressure Compaction
Pure alumina and alumina-titanium diboride ceramic composites were produced using plasma pressure compaction sintering and compared for hardness, elastic modulus, and fracture toughness. The composite material showed improved performance in some mechanical properties compared to pure alumina. These findings support the development of high-performance ceramic materials for industrial applications.
Effects of Grain Size and Humidity on Fretting Wear in Fine‐Grained Alumina, Al 2 O 3 /TiC, and Zirconia
This tribology study examined how grain size and humidity affect wear in ceramic materials (alumina and zirconia) under fretting conditions, finding that smaller grain sizes reduce wear through microplastic deformation of grain boundaries. This is a ceramics engineering study where 'microplastic deformation' refers to sub-yield material behavior, not environmental plastic particles.
The effects of oil-quenching and over-tempering heat treatments on the dry sliding wear behaviours of 25CrMo4 steel
Researchers tested how different heat treatments affect the wear resistance of 25CrMo4 steel used in automotive parts, finding that oil-quenching and over-tempering significantly reduced material wear loss compared to untreated steel, even when hardness slightly decreased — important for extending the life of industrial components.
High-Temperature Solid Lubricants and Self-Lubricating Composites: A Critical Review
This review examined high-temperature solid lubricants and self-lubricating composites used in extreme conditions such as aerospace and metallurgy, covering material properties, mechanisms, and recent advances in reducing friction and wear at elevated temperatures.
Study on Microstructure Evolution Mechanism of Gradient Structure Surface of AA7075 Aluminum Alloy by Ultrasonic Surface Rolling Treatment
Not a microplastics paper — this materials science study investigates how ultrasonic surface rolling treatment changes the grain structure of aluminum alloy surfaces at the nanoscale, improving strength and fatigue resistance for engineering applications.
Tribological Aspects of Rolling Bearing Failures
This review covers the tribology (friction and wear science) of rolling element bearings, discussing failure modes and how material fatigue drives bearing lifespan predictions. This mechanical engineering study has no relevance to microplastics or environmental health.
