Summary: Aluminium matrix composites (AlMCs) of AA7075 aluminium alloy reinforced with 0.5 and 1 wt.% multiwall carbon nanotubes (MWCNTs) were fabricated using powder metallurgy techniques with varying mechanical milling strategies. The dispersion of MWCNTs was found to be influenced by milling conditions and MWCNT content. The best distribution of reinforcements was achieved by milling 7075 powders and MWCNTs in a high-energy cycle (HEBM) at a rotation speed between 1200 and 1300 rpm. Raman spectroscopy showed no damage to the nanotubes during the milling process, and nanoindentation tests revealed that the 7075-0.5 wt.% MWCNT composites had the best mechanical behavior.

Summary: The study investigated the impact of metal powder characteristics on graphene structure during the ball milling process. It found that metal particle size has a minor influence in low-energy ball milling, but plays an important role in high-energy ball milling. Increasing ball milling energy leads to increased structural defects in graphene, with limited damage when there is a large discrepancy in particle size.

Summary: In this study, a TiAlSiN thin film with a CrN interlayer deposited on hardened DAC-10 tool steel was tested against tungsten carbide to evaluate its wear performance. The relative effect of four independent wear parameters, including temperature, sliding distance, applied load, and sliding distance, on wear responses such as wear rate, friction coefficient, surface roughness, wear depth, and hardness was optimized and evaluated using Taguchi and multi-objective decision-making methods. The optimized wear parameters were determined, and the wear mechanism was investigated for both the best and worst alternative wear conditions.

Summary: This study investigated the effects of tribological process parameters and their optimization on the wear responses of a TiAlN thin film on MDC-K hot work tool steel. The researchers conducted a tribological test and analyzed the effects of sliding velocity, applied load, and sliding distance on friction coefficient, surface roughness, wear depth, wear mass loss, and hardness. Contour plots and analysis of variance were used to study the relative effects of the process parameters. The optimal settings were determined using an overall evaluation criteria method based on experimental results, and the wear mechanisms were examined using scanning electron microscopy and energy-dispersive X-ray spectroscopy.

Summary: Studies on MCDM techniques for analyzing wear parameters of ceramic coatings are limited. This study proposes a novel fuzzy integrated PSI-CODAS method to analyze and rank alternative wear parameters for Cr2O3/TiAlN coating. A full factorial DOE is conducted to evaluate the wear characteristics of the coating, and sensitivity analysis is performed to examine the effect of criteria weight on the ranking of alternatives. Results show that alternative 42 remains the best choice for optimal wear responses in Cr2O3/TiAlN coating. The method is compared with five other fuzzy integrated MCDM methods.
