Special Issue Information

Dear Colleagues,

In engineering applications, the safety, reliability, high efficiency, low consumption and environmental optimization of equipment are important for the development of a low-carbon economy. However, the gradual degradation of special materials leads to gradual changes in their dynamic response and thermal load characteristics, resulting in an unstable working quality and the failure of equipment. Therefore, the monitoring and evaluation of the degradation of special materials is a key issue for high-end equipment in order to achieve reliable operation and healthy service.

The main purpose of this Special Issue, entitled “Evolution of the Working Performance of Special Materials during the Whole Life Cycle”, is to find solutions to the difficulties and challenges encountered in the quantification, monitoring and evaluation of the working performance of special materials in the whole life cycle. This research field covers the reviews, principles, and methods of the overall performance of special materials, including formation and preparation processes, whole-life performance monitoring, quantification and evaluation, optimal working condition design, etc. The main areas of interest include, but are not limited to, the manufacturing and processing of composites, the quantitative characterization of micro-morphology and the friction coefficient, the identification of material deformation and failure, the evalution of noise and vibration, oil detection technology for worn materials, numerical simulation and experimental methods for the evaluation of friction wear, dynamic response, and thermal load characteristics. We welcome the submission of papers addressing the monitoring, quantification and evaluation of the working performance of special materials in the whole life cycle, from the perspective of the development of applications.

The paper investigates various methods of microfinishing and arrives at the best technique to produce a very smooth surface. Various setups, with and without oscillation, were developed, together with a microfinishing attachment used on conventional lathes and milling machines. The workpiece material used was an amorphous nickel–phosphorus Ni–P alloy. The surface roughness parameters, such as Sa, Sv, and Sp, were measured with the TalySurf CCI6000 instrument. For the measurement of the surface protrusions, an “analysis of islands” technique was used at various levels of cut-off. The 2BA method—machining below the workpiece axis with oscillation—turned out to be the most effective method applied because it had the highest density of protrusions while having the smallest value of surface roughness. Non-oscillation with the machining zone below the axis also becomes effective, indicating that repositioning can compensate for a lack of oscillation. Already, the very compact surface structure achieved with minimized depths in the valleys by the 2BA method supported the improvement in tribological performance and increase in load-carrying capacity, together with lubricant retention enhancement. These results show that the microfinishing process can be optimized by parameter tuning, and also, non-oscillating methods could come to be a practical alternative, probably reducing the complexity of equipment and cutting costs. Further studies need to be aimed at the scalability of these methods and their application to other materials and fields. Full article

Stainless steel grade 430 is a type of soft magnetic electromagnetic material with rapid magnetization and demagnetization properties. Considering the delay phenomenon during operation, this study selected 430 stainless steel as the material and explored various metallurgical methods such as magnetic annealing and the addition of Mo as well as increasing the Si content to investigate the microstructure, mechanical behavior, and magnetic properties of each material, aiming to improve the magnetic properties of 430 stainless steel. Experimental results showed that the four electromagnetic steel materials (430F, 430F-MA, 434, and KM31) had equiaxed grain matrix structures, and excellent tensile and elongation properties were observed for each specimen. Additionally, the magnetic properties of the 430F specimen were similar under the DC and AC-10 Hz conditions. According to the hysteresis curves under different AC frequencies (10, 100, 1000 Hz), both magnetic annealing and the addition of Mo could reduce the Bm, Br, and Hc values of the raw 430F material. Increasing the Si content resulted in a decrease in Hc values and an increase in Bm and Br values. Full article

The reduction of friction-induced noise is a crucial research area for enhancing vehicle comfort, and this paper proposes a method based on circular pit texture to achieve this goal. We conducted a long-term sliding friction test using a pin-on-disc friction and a wear test bench to verify the validity of this method. To compare the friction noise of different surfaces, texture units with varying line densities were machined on the surface of friction disk samples. The resulting friction-wear and noise characteristics of the samples were analyzed in conjunction with the microscopic morphology of the worn surfaces. The results indicate that surfaces with textures can delay the onset of squeal noise, and the pattern of its development differs from that of smooth surfaces. The noise reduction effect is most evident due to the proper distribution of textures that can form furrow-like wear marks at the wear interface. The finite element results demonstrate that this morphology can improve pressure distribution at the leading point and reduce the tendency of system instability. Full article
