Assessment of Wear rate and Coefficient of Friction of Al6262 WC/MoS2 under wet sliding condition

The present paper aims at the results of an experimental examination of hybrid metal matrix composites using stir-casting technique.Aluminum alloy (Al 6062) samples reinforced with Tungsten Carbide (WC) and Molydedneum diSulphide are given. 2wt.% , 4wt.%,6wt.% of MoS2 and 3 wt.%, 6 wt.%, 9 wt.% tungsten carbide were mixed together with the aluminum alloy to create the hybrid composite. The tribological aspects of aluminium composites were studied using Pin on disc Method under wet sliding condition.Testing the hybrid composites' hardness revealed that raising the weight percentage of tungsten carbide might raise the hybrid composites' hardness. To examine the wear behavior of hybrid composites, the Taguchi method was utilized in the design of experiments (DOE) approach. The factors that were found to affect wear rate included load, sliding speed, and reinforcing percentage of WC and MoS2 are the most influencing parameters

Study of mechanical behaviour & microstructural properties on friction stir welded aluminium alloys 6082 - t6&8011

In this study 6082 T6 aluminium alloys and 8011 aluminium alloys of 5mm Thickness by using a friction stir welding procedure, plates were connected. weldments are carried out by varying various parameters such as Tool rotational rates are varies from(600 rpm,800 rpm,1000 rpm),Traverse speed are varies from(10 mm/min,20 mm/min,30mm/ min) Axial Forces are varies from (4 kn,6 kn,8 kn) and Tilt angle maintains 10.This process performed by nonconsumable tool as Hexagonal,cylindrical and square pin profiles to generate a heat energy and plastic atomic diffusion's are made in the weldments. The fractography microstructure of tensile specimen shows minimum failure when the tool rotational speed is 800rpm, traverse speed at 20 mm/min and axial force 8KN

Investigation on the Mechanical Properties of Silicon Carbide Particulates in Al/SiC/MoS<sub>2 </sub>

The present study aims to optimize the mechanical properties of Al5059/SiC/MoS2 hybrid composites. The hybrid metal matrix composites has been fabricated through stir casting by reinforcing different size of SiC (10,20&amp;40 µm) with aluminium at different weight fractions (5 %,10% &amp;15%) meanwhile the addition of Molybdenum di sulphide (MoS2) is fixed at 2% which enhances the self lubrication properties. The basic mechanical properties were investigated and the composite with minimum particle size shows high mechanical strength</jats:p

Fabrication and characterization of TiO₂ particulate filled agave Americana fiber-reinforced polyester resin composites

Purpose In this study, TiO2 is used to enhance the mechanical properties of the composite material containing agave Americana fiber and polyester resin. Design/methodology/approach Agave Americana fiber was first treated with 5% of NaOH, and the composition of treated and untreated fiber was kept constant, whereas the particulate and resin were alternatively used. The handlay method is used to fabricate the composite plates. The morphology of the composites was studied using scanning electron microscopy (SEM). Findings The composite was composed of 30% treated agave Americana, 10% of TiO2 particulates and 60% of a polyester resin for better and enhanced mechanical properties. Practical implications The composite can be used for aero-structural components, automobile components and other areas where light-weight components are required. Originality/value A new type of agave Americana fiber with TiO2 and polyester resin composite was fabricated and investigated. </jats:sec
