Summary: This study investigated the potential increased toxicity due to combined radiation and cobalt-chromium (CoCr) exposure using a controlled in vitro model. The results showed that CoCr and radiation had additive and synergistic effects on cell survival, reducing viability and increasing apoptosis and oxidative stress. Further research using different experimental models is warranted to determine the translational impact of these observations.

Summary: The effects of potential, normal load, and cycles on volume abraded and fretting currents were studied for CoCrMo, Ti-6Al-4 V, and 316 L SS in a phosphate buffered saline solution. The tribocorroded regions were examined using microscopy and spectroscopy. Fretting currents were compared to the predictions of the Gilbert 2020 model. The currents varied as expected based on the alloy, potential, and load. The charge released decreased over time due to oxidation wear track, but it was linearly related to the volume removed. The average fretting corrosion currents during the initial 100 cycles indicated that only a small fraction (5-16%) of the wear volume was due to electrochemical processes, with the majority attributed to plastic deformation and metal wear particle generation. The highest currents occurred at the beginning and then steadily dropped to less than half of the initial value due to rapid filling of the oxide wear track.

Summary: This study examines the aqueous corrosion and wear performance of TiC-Ni3Al cermet coatings deposited by HVOF thermal spray. The results show that HVOF sprayed TiC-Ni3Al cermet coatings demonstrate higher wear and corrosion resistance compared to conventional WC-Co and WC-CoCr cermet coatings.

Summary: This paper investigates the effect of debris on surface wear and damage evolution during contact sliding. The findings show that debris removal can considerably alter surface damage evolution and its influence depends on the surface properties of the contact pair.

Summary: Graphene-based solid lubricants biofunctionalized with hyaluronic acid were applied on CoCr surfaces to reduce wear-corrosion phenomena. Graphene oxide was electrochemically reduced on CoCr in a suspension of graphene oxide 4 g/L by cyclic voltammetry. Biofunctionalization was performed in phosphate buffer solution with HA 3 g/L (PBS-HA) for 24 h. Tribocorrosion tests were conducted using a pin-on-disk tribometer with an integrated cell, applying a normal load of 1 N, 120 rpm for 500 m, in both PBS and PBS-HA. The coefficients of friction in PBS were higher than those in PBS-HA. ErGO and HA-ErGO increased the wear rate in AISI316 balls, indicating that ErGO hardened the CoCr surface. Biofunctionalization reduced the abrasive properties of ErGO deposits.

Summary: This study comparatively investigates the characteristics of fretting and sliding wear debris produced by CuNiAl against 42CrMo4. The wear scar profiles, debris color, distribution, and amount generated under the two wear modes are significantly different, attributed to the distinct wear mechanisms.

Summary: The study characterized macropits on gear moulds and sampled wear particles using optical microscopy, revealing that the concentration of wear particles had a similar trend to pitted area growth, yet with a delay. This behavior was also reflected in four non-dimensional numerical features characterizing the geometry of particles and pits.

Summary: The study found that despite changes in test parameters such as angular velocity, loads, and sliding distances, the specific wear rate values and prevailing wear mechanism of HVAF-sprayed WC-CoCr coatings remained relatively stable, indicating that the wear regime did not dramatically change within the range of test conditions investigated.

Summary: Quercetin, a natural flavonoid found in fruits and vegetables, has been shown to have multiple beneficial effects in organ damage and diseases, making it a potential health-promoting supplement. Previous studies have demonstrated its protective effect on reproductive function, possibly due to its antioxidant, anti-inflammatory, and anti-apoptotic properties. This paper reviews the mechanisms and role of quercetin in testicular damage, as well as its application in clinical trials, showing its practical effects in regulating blood pressure and inhibiting cellular senescence. However, more in-depth studies and trials are needed to confirm its true value in preventing and protecting against testicular injury.

Summary: Aseptic loosening is mainly caused by wear particles induced inflammatory response and subsequent bone loss. This study investigated the activation of the NLRP3 inflammasome by different metal particles in in vitro and in vivo conditions. The results showed that CoCrMo particles induced more inflammasome formation compared to TiAlV particles. Additionally, NRLP3 inflammasome activation was increased only by CoNiCrMo particles. These findings suggest that different alloys activate different inflammatory pathways.

Summary: This study evaluated the effect of feedstock particle size and nozzle configuration on HVAF-sprayed WC-CoCr coatings. It was found that decreasing feedstock particle size resulted in changes in microstructural features and improved performance of the coatings. The type of nozzle used also had an impact on the sensitivity of fine and coarse feedstock powders, while medium cut size powders showed no major difference in coatings sprayed with different nozzles.
