“…Transition metal carbides have found applications in industry. They are used as additives to materials for improving their strength [13], cermet materials [14], protective coatings [15], refining layers of cutting tool blades [16,17], and balls and ball bearing raceways [18]. Metal carbides have also found application in various branches of catalysis, such as hydrotreatment including hydrodesulfurization, hydrodenitrogenation, and hydrodeoxygenation-for removal of heteroatoms (S, N, O) from hydrocarbons.…”

Dry reforming of hydrocarbons (DRH) is a pro-environmental method for syngas production. It owes its pro-environmental character to the use of carbon dioxide, which is one of the main greenhouse gases. Currently used nickel catalysts on oxide supports suffer from rapid deactivation due to sintering of active metal particles or the deposition of carbon deposits blocking the flow of gases through the reaction tube. In this view, new alternative catalysts are highly sought after. Transition metal carbides (TMCs) can potentially replace traditional nickel catalysts due to their stability and activity in DR processes. The catalytic activity of carbides results from the synthesis-dependent structural properties of carbides. In this respect, this review presents the most important methods of titanium, molybdenum, and tungsten carbide synthesis and the influence of their properties on activity in catalyzing the reaction of methane with carbon dioxide.

“…The performance of gas turbine deteriorates with so many factors, and the primary one may be related to its mechanical nature (Kwon and Lee, 2021; Salilew and Karim, 2021). As a pillar of supporting heavy radial loads, roller bearings can work under harsh and unstable conditions, so higher failure rates and repair costs are inevitable (Liu et al , 2020; Jalaja et al , 2021). In addition, service environment has been considered as a great influence on the reliability in service life, because the thin oil film can protect the rolling contact surface by avoiding rollers or balls contacting the raceway directly (Liu et al , 2020).…”

Purpose Ball bearings in gas turbine have played a critical role in supporting heavy radial loads but with higher failure rates and repair costs. Therefore, the purpose of this study is to introduce and study a method for their failure analysis with an actual industrial example to guarantee operation reliability and safety. Design/methodology/approach Spectrometric oil analysis was used as an early abnormal wear indicator, based on which emergent in-use oil replacement was carried out to reduce the wear rate. However, with wear deterioration, further wear failure investigation was conducted by LaserNet Fines and ferrography to detect the imminent wear failure. Finally, with the assistance of elemental analysis of the typical wear particles, the root cause and worn components were determined by scanning electronic microscope and energy-dispersive X-ray spectroscopy. Findings The results have shown that an extraneous source led to wear failure, which later caused overheat between the outer bearing ring and ball. It is in accordance with visual inspection of the disassembled engine. Originality/value This method has specified the occasion under which the suitable measurement can be taken. It can achieve the rapid wear condition assessment allowing for root cause and worn parts identification. In addition, wear rate reduction by change of oil can be efficient for most of the time to avoid premature disassemble, especially with the possibility of contamination. It has provided experience to address similar industry-level practical wear failure analysis problems.
