Friction Behavior of Molybdenum Disulfide/Polytetrafluoroethylene-Coated Cemented Carbide Fabricated with a Spray Technique in Dry Friction Conditions
Published on 2025-03-11 by Li Zhang, Wenlong Song @MDPI
Abstract: Cemented carbide has a relatively high surface friction coefficient, which can result in increased wear and energy consumption during friction, ultimately impacting service life and efficiency. In order to improve the tribological properties of the traditionally cemented carbide, the MoS2 and PTFE (25 wt.%) mixed powders, which were blended with Polyamide-imide (PAI) as the adhesive, were sprayed on the carbide surface at 70 °C. Tests were used to measure the performance of MoS2/PTFE[...]
Our summary: Improvement of tribological properties of cemented carbide by spraying MoS2/PTFE coatings with PAI adhesive at 70°C resulted in reduced friction coefficient by about 70%, adhesion strength up to 36 N, and hardness of 0.42 GPa.

YTaO4/Y₂Zr₂O₇ Dual-Phase Ceramics with Enhanced Vickers Hardness, Fracture Toughness and High Thermal Expansion Properties for Thermal Barrier Coating Applications
Published on 2025-03-11 by Ziyang Ruan, Zifan Zhao, Jing Feng @MDPI
Abstract: Rare-earth tantalates (RETaO4) are considered as a type of emerging thermal barrier coating materials applied to the hot components of gas turbines and aerospace engines due to their excellent thermal stability, high-temperature fracture toughness, corrosion resistance and extremely low thermal conductivity. However, the relatively low hardness and thermal expansion coefficients may limit their service lifetime in a harsh engine environment. To address the current limitation of rare-earth tantal[...]
Our summary: Rare-earth tantalates (RETaO4) are excellent thermal barrier coating materials for gas turbines and aerospace engines. Introducing YTaO4/YZrO7 dual-phase ceramics significantly enhances mechanical and thermal properties, making them ideal for thermal barrier coating applications.

Performance Assessment of Graphene Oxide as a Protective Coating for Historical Stone
Published on 2025-03-11 by Codrut Costinas, Liviu Cosmin Cotet, Lucian Baia, Naida El Habra, Luca Nodari, Patrizia Tomasin @MDPI
Abstract: Stone cultural heritage faces significant deterioration from environmental factors, necessitating protective treatments that preserve both functionality and appearance. In this study, graphene oxide (GO) was evaluated as a protective coating for both natural and artificially aged Euganean trachyte and Vicenza stone samples. GO was applied as a low-concentration aqueous dispersion (0.5 mg/mL) by brush, and samples were subsequently exposed to UV light for 7 h to simulate weathering. Performance w[...]
Our summary: Evaluation of graphene oxide as a protective coating for historical stone samples shows promising results in reducing water absorption and maintaining vapor permeability. UV exposure darkens the coating but enhances hydrophobicity, indicating potential for stone protection. Further research is needed to optimize coating uniformity and assess long-term durability.

Effect of Partial Fibre Laser Processing on the Wear Resistance of NiCrMoFeCSiB Coatings
Published on 2025-03-11 by Olegas ?erna�?jus, Jelena �kamat, ?ukasz Gierz, Olga Zharkevich, Alexandra Berg @MDPI
Abstract: Surface laser processing of metallic materials is known to be effective in improving wear resistance due to microstructure refinement and the associated hardening effect. However, the formation of cracks, which frequently accompanies such processing, remains a challenge. This work focusses on partial laser processing of Ni-based protective coatings as a method that could potentially reduce the risk of crack formation due to lower overall heat input and retaining softer material portions that fac[...]
Our summary: Effect of Partial Fibre Laser Processing on Wear Resistance of NiCrMoFeCSiB Coatings. Laser processing of Ni-based coatings improves wear resistance by refining microstructure and hardening material. Partial laser treatment reduces crack formation risk and enhances wear resistance significantly.
