Special Issue Information

Dear Colleagues,

Tribology and corrosion represent two pivotal areas of research in materials science, since they directly influence the service life and reliability of engineered systems across the aerospace, energy, biomedical, and manufacturing sectors. The interplay between mechanical wear and electrochemical degradation poses complex challenges that drive the development of novel materials and protective coatings. Advancements in characterization methodologies, predictive modeling, and surface engineering continue to unveil new mechanisms and strategies for enhancing material performance in severe operational environments. 

This Special Issue of Coatings is dedicated to the “Tribological and Corrosion Characterization in Advanced Materials and Coatings.” It aligns closely with the journal’s focus on surface treatments, functional coatings, and interfacial phenomena, providing a platform for cutting-edge research that bridges fundamental understanding and practical application. We aim to compile a curated collection of at least 10 high-quality articles that offer substantial insights into these domains. Upon reaching this threshold, the Special Issue may be considered for publication as a book, ensuring broader dissemination and impact.

The scope of this Special Issue includes, but is not limited to, the following topics: 

  • Development and testing of coatings for tribological applications;
  • Corrosion-resistant material design and evaluation;
  • Innovative methods for characterizing wear and corrosion;
  • Degradation mechanisms in high-performance materials and composites;
  • Surface modification techniques to improve tribo-corrosion resistance;
  • The role of microstructure and interface design on coating durability;
  • Computational and predictive modeling of tribological and corrosion behavior;
  • Real-world applications and case studies in industry.

A 7224C high-speed angular contact ball bearing used in a multi-wire sawing machine is selected as the research object to investigate the cage dynamic characteristics under oil-lubricated operating conditions. First, in order to determine the oil-phase volume fraction on the cage surface, a fluid-domain model of the bearing cavity is established, and numerical simulations are performed using the VOF multiphase-flow method coupled with the RNG k-ε turbulence model. The effects of the guiding clearance, pocket clearance, and rotational speed are analyzed, and a regression equation for the cage-surface oil-phase volume fraction is developed based on a uniform test design. Subsequently, a bearing dynamic model is constructed, in which lubrication-related parameters are determined based on the regression equation, and the force balance and equations of motion for each component are derived. Finally, using the slip ratio and the deviation ratio of the cage-centroid whirl velocity as evaluation indices, the influences of multiple parameters on cage stability are examined. The results indicate that increasing the clearances and rotational speed leads to a higher slip ratio, whereas increasing the axial and radial loads reduces the slip ratio. Moreover, enlarging the guiding clearance and increasing the axial load improve cage stability, while a larger pocket clearance and an excessively high radial load deteriorate cage stability.

Based on the rectifying conduction principle of the Tesla valve, a self-pumping hydrodynamic mechanical seal with Tesla valve-shaped face grooves was proposed, and its corresponding computational model was established. Numerical simulations were conducted to investigate the effects of the Tesla valve diversion angle and valve clearance on the sealing performance of the proposed structure. Taking the leakage rate and liquid film stiffness as the target performance indices, a predictive model was developed by combining uniform experimental design with multiple regression analysis. Subsequently, the NSGA-II (Non-dominated Sorting Genetic Algorithm II) genetic algorithm was employed for bi-objective optimization to obtain the Pareto-optimal solution set, and the TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) method was further applied to identify the optimal combination of structural parameters under specified weighting coefficients. The results indicate that the leakage rate is not significantly affected by variations in the diversion angle or valve clearance, whereas the liquid film stiffness increases with increasing diversion angle and decreases with increasing valve clearance. Multi-objective optimization successfully identified an optimal parameter combination that improves the overall sealing performance of the proposed structure. This study provides a novel perspective and theoretical basis for innovation in face structure and for the performance optimization of self-pumping mechanical seals. Full article

Understanding the microscopic interaction between agricultural tillage tools and soil is essential for improving wear resistance. In this study, molecular dynamics (MD) simulations are employed to investigate the tribological behavior of the Fe–SiO2 interface under varying loads and sliding velocities. The results demonstrate that the coefficient of friction increases with both normal load and sliding velocity, accompanied by a clear running-in stage. Under high loads, significant plastic deformation occurs, characterized by asymmetric atomic pile-up, expansion of the strain field, and heterogeneous von Mises strain distribution. Energy analysis reveals intensified kinetic and potential energy variations, indicating enhanced defect accumulation and interfacial non-equilibrium states. Temperature distributions are highly localized at the interface, with thermal saturation observed under high-velocity conditions. Mean square displacement (MSD) results confirm that higher loads and velocities promote atomic migration and plastic flow. This study provides atomic-scale insights into wear mechanisms under extreme mechanical conditions, offering theoretical support for the design of durable soil-engaging components in agricultural machinery.
