Special Issue Information

Dear Colleagues,

Various industrial processes require the application of advanced materials that are resistant to corrosion in order to prevent or decrease losses due to wear, reduce the downtime of equipment that is in contact with an aggressive environment, and increase efficiency and process quality. Therefore, the production of inorganic non-metallic materials, such as advanced ceramics, is economically very important, and it is one of the most attractive economic branches in developed countries. Numerous possibilities for the application of ceramic products are based on the specific properties of ceramic materials. The chemical, mechanical, and tribological properties of advanced ceramics depend on several parameters, such as chemical composition, microstructure, and surface condition, which are the most influential parameters. The chemical composition of ceramic materials varies significantly from simple compounds to mixtures of many complex phases. The proper selection of raw materials and the optimization of the sintering process are also very important steps.

Advanced ceramics, as a new class of ceramic materials with a unique combination of corrosion and wear resistance and high temperature stability, have a growing application potential for the wear and corrosion protection of different working parts in the mining and mineral industries. These working parts have to withstand a continuous flow of hard abrasive particles, often in highly corrosive environments, flowing at high velocities and pressures.

This Special Issue will focus on mechanical properties, resistance to various wear mechanisms, and the factors that affect the chemical stability (i.e., corrosion) of various types of advanced ceramics. It is our pleasure to invite you to submit a manuscript for this Special Issue. Topics on all aspects of corrosion, wear, and mechanical properties of advanced ceramics are suitable for this Special Issue. We welcome full papers, communications, and reviews. We look forward to your contributions.

Composite sintered bodies comprising silicon dioxide (SiO2) nanoparticles dispersed in β-tricalcium phosphate (β-TCP) were prepared. The addition of nano-sized colloidal SiO2 to the β-TCP produced well-dispersed secondary phase nanoparticles that promoted densification by suppressing grain growth and increasing linear shrinkage of the sintered bodies. The SiO2 was found not to react with the β-TCP at 1120 °C and the substitution of silicon for phosphorous to produce a solid solution did not occur. This lack of a reaction is ascribed to the absence of available calcium ions to compensate for the increase in charge associated with this substitution. The SiO2 nanoparticles were found to be present near the intersections of grain boundaries in the β-TCP. β-TCP composite sintered body containing 2.0 and 4.0 wt% SiO2 exhibited a bending strength comparable to that of cortical bone and hence could potentially be used as a bone filling material.

Ceramic panel collapse will easily lead to the failure of traditional targets. One strategy to solve this problem is to use separate ceramic units as armor panels. Based on this idea, we propose an aluminum matrix composite using pressure infiltration, containing an array of ceramic balls, the reinforcement of which consists of centimeter-scale SiC balls and micron-scale B4C particles. Three different array layouts were designed and fabricated: compact balls in the front panel (F-C), non-compact balls in the front panel (F-NC), and compact balls inside the target (I-C). The penetration resistance properties were tested using a 12.7 mm armor-piercing incendiary (API). The results show that there are no significant internal defects, and the ceramic balls are well-bonded with the matrix composite. The F-NC structure behaves the best penetration resistance with minimal overall damage; the I-C structure has a large area of spalling and the most serious damage. Finite element simulation reveals that the ceramic balls play a major role in projectile erosion; in the non-compact structure, the composite materials between the ceramic balls can effectively disperse the stress, thereby avoiding the damage caused by direct contact between ceramic balls and improving the efficiency of ceramic ball erosion projectiles. Furthermore, it is essential to have a certain thickness of supporting materials to prevent spalling failure caused by stress wave transmission during penetration. This multi-scale composite exhibits excellent ballistic performance, providing valuable insights for developing anti-penetration composite armor in future applications. Full article
