In India, urban solid waste generation has risen over the last decade. The aspect of waste generation is a large amount of waste materials among all solid waste types. While using ash particles eliminates waste, it also contributes desirable qualities. In this research work, the effects of Himalayan nettle leaf ash (HNLA) bean pod ash (BPA) with molybdenum trioxide (MoO3) on the ZWK611 (Mg-Zn6.0-Y1.2-Zr0.2) alloy is examined. The as-cast alloy exhibits an α-Mg matrix, and cubic γ-phases are formed in addition to MoO3 particles. In this work, an attempt was made to choose a ZWK611 alloy reinforced with HNLA and BPA by varying weight percentages (X = 4, 8, 12, and 15%) with a constant weight percentage of MoO3 (5%) fabricated using spark plasma sintering (SPS) technique. The mechanical and physical properties were tested for both as-cast alloy and magnesium hybrid composites. Surface morphology and XRD are analysed to identify material behaviour. The addition of 12%(HNLA-BPA)/5%(MoO3) hybrid composite exhibits high strength as compared to the as-cast alloy.

“…For higher sliding speed, the time is low and the oxide layer is easier to form. The oxide layer protects the matrix surface during the wear test [96]. As a result, the wear curves of the samples had a steeper tendency to increase at low speed.…”

The demand for magnesium (Mg) alloys is increasing in many industries, such as automotive and aerospace, thanks to their low density and high specific strength. However, the poor tribological performance of Mg alloys is one of the most important disadvantages that limit their widespread use. Researchers have developed different approaches to improve the wear performance of Mg alloys, such as alloying, coatings, surface modifications and composite production. Wear performance of systems with sliding parts are crucial for a lifetime and energy efficiency. The development of Mg matrix composites can significantly reduce energy loss by reducing damage from friction and wear. For this reason, it is crucial to understand the wear behaviour of recent Mg matrix composites. The effect of different parameters such as load, sliding speed, reinforcement content, reinforcement type and temperature on the wear performance of Mg matrix composites were investigated.

The objective of this research is to introduce a mathematical model of wear volume of Archard's equation influenced by speed variable. Some researchers have studied the wear volume due to sliding speed, roughness and coefficient of friction. However, mathematical model dealing with sliding speed has never been explicitly reported. Wear analysis is oftenly expressed experimentally through charts concerning both wear volume and sliding speed instead of mathematics. This research is started by modeling mathematical representation within Buckingham Pi Theory. The mathematical parameter contains wear volume, hardness, normal loads, sliding speed, sliding distance, and density of materials. Buckingham Pi model produces three sets of equation. Two of these sets yields Archard's equation. By combining the third set, the modified Archard's equation is determined. Since Buckingham set requires a constant of equality, the equation is verified by experiment data. This value is called Wear-Speed Coefficient. Experiment using pin-on-disk tribometer is conducted by varying sliding speed. Further more, those parameters are applied to estimate wear volumes. Materials which are used for this verification are NBR Rubber Nitril, Ultra High Molecular Weight Poly Ethylene (UHMWPE), and Poly Tetra Fluoro Ethylene (PTFE). In conclusion, the modified Archard equation is determined to estimate wear volumes. Based on the experiment, the model is accurate for UHMWPE, NBR and PTFE. Moreover, ratio of density to material's hardness is significant to control wear resistance influenced by speed.
