Parametric optimization of COF of fabricated AA6082/Si3N4/C/Al2O3 composite
Abstract: In the present experimental investigation AA6082/Si3N4/C/Al2O3 composite was successfully fabri-cated using stir casting technique combined with electromagnetic stirrer for wear resistance applica-tions. The produced AA6082/Si3N4/C/Al2O3 composite exhibits improved tribological and me-chanical and properties, according to the experimental results. The generated composite has a micro-hardness range of 60 to 110 HV and an average UTS of 150 to 200 MPa. The tribological perfor-mance was evaluated using a pin on disc tribometer. …

Investigation on Dry Sliding Wear Behaviour of AlSi7Mg0.3/B4C/ZrO2 Hybrid Composites using Taguchi Method
Abstract: Hybrid Aluminium/Boron carbide/Zirconium oxide (AlSi7Mg0.3/B4C/ZrO2) composites were fabricated utilizing stir casting technique by varying boron carbide content (4wt.%, 8wt.% and 12wt.%) and utilizing a fixed amount (4wt.%) of zirconium oxide particles. Optical microscopy revealed that B4C and ZrO2 particulates were dispersed uniformly in AlSi7Mg0.3 matrix. Dry sliding wear experiments were carried out utilizing the pin-on-disc tribometer with various levels of applied loads, sliding speeds and weight percentage of boron carbide …

Tribological Performance and Wear Coefficient Prediction of AA2024–TiC Composites via Python-Based Machine Learning
Abstract: Determining wear coefficient accurately serves as a critical factor to maximize engineering materials' tribological characteristics. The experiment examines the wear characteristics of TiC-reinforced AA2024 aluminum alloy subjected to different tribological operating conditions. A pin-on-disc tribometer performed wear tests under different conditions of load and TiC weight fraction and sliding speed and duration. ANOVA statistical results show that load intensity and TiC reinforcement density stand out as principal variables that affect …

Optimizing Parameters for Dry Sliding Wear Control in Stir-Cast AA7050/SiC Composites
Abstract: Using a pin-on-disc tribometer, this study examined the dry sliding wear behavior of AA7050/SiC composites. The production of this metal matrix composite was achieved through the stir-casting process, which involved an initial step of melting the AA7050 alloy, followed by the careful introduction of silicon carbide (SiC) particles, stirring to achieve uniform dispersion, and finally, casting the molten mixture. Wear rate (WR) was determined by three operational parameters: SiC reinforcement …

Nanostructured Cr-WS2 Solid Lubricant Coating for Space Applications
Abstract: Abstract Tungsten disulphide (WS2) is one of the widely used intrinsic low friction materials, which is commonly used in the form of coating. WS2 offers very low coefficient of friction only in non humid conditions. Presence of humidity destroys this property and restricts its utility. Modifying the structure of WS2 by adding certain metals helps in overcoming this limitation and in addition improves the mechanical properties. Further, deposition technique and …
