“…Since magnesium composites have several advantages compared to monolithic magnesium and its alloys, numerous studies have been conducted on magnesium based composites [3][4][5][6][7][8][9][10][11]. Hassan et al [10] studied microstructure and mechanical properties of the magnesium reinforced with Y 2 O 3 .…”

“…In spite of the attractive range of mechanical properties, relatively low strength, both at the ambient temperature and elevated temperatures, and poor resistance to wear and corrosion are a serious impediment to a wider application of magnesium alloys, comparable to the wide use of aluminium alloys. A further improvement in mechanical properties has been A.Lakshmanan Pillai, G.R.Jinu, G.Karthikeyan Fabrication and Tribological Behaviour of Mg-TiO 2 Composites required to extend the application of magnesium alloys [3,4]. Several researchers reported that the addition of hard ceramic particles to magnesium resulted in better wear resistance and improved mechanical properties and thermal stability [5][6].…”

“…In the integrated circuit industry, lightweight metals are used as replacements for plastics [1,2]. Among the advantages of magnesium and its alloys used as composite matrices are excellent specific strength and stiffness, good damping capacities, and dimensional stability [3]. In spite of the attractive range of mechanical properties, relatively low strength, both at the ambient temperature and elevated temperatures, and poor resistance to wear and corrosion are a serious impediment to a wider application of magnesium alloys, comparable to the wide use of aluminium alloys.…”

SummaryIn the present study pure magnesium was taken as a base metal which is reinforced with various weight percentages of TiO 2 (2.5, 5, 7.5, 10 % wt). This is done through a vacuum stir casting route with argon as a shielding gas to prevent oxidation. The prepared samples were machined using the Electric Discharge Machining (EDM) to achieve accurate dimensions for the study of tribological properties. A computerized pin-on-disc machine is used to study the dry sliding wear behaviour of the Mg-based composites. Wear losses were calculated using a variety of load parameters (10N, 15N, 20N, and 25N), sliding velocities (1 m/s, 1.5 m/s, and 2.0 m/s) and the weight percentage of the reinforcement. The results proved that the wear loss increased with an increase in the load, and decreased with an increase in the sliding velocity. The wear resistance is improved with an increase in the percentage of reinforcements in the matrix. The morphology and distribution of reinforcements were analysed by means of Scanning Electron Microscopy (SEM) and Energy-Dispersive X-ray (EDX) spectroscopy, respectively. The results revealed a uniform distribution of TiO 2 particles throughout the magnesium matrix in the Mg-TiO 2 composites.

“…The previous investigations have demonstrated that micro alloying [2], cryogenic treatment [3,4], hot working [5,6] and introduction of some dispersoids [7] could effectively improve the surface microstructure to enhance friction and wear properties of Mg alloys. For example, some dispersoids, such as fine ceramics and oxide particles, are usually introduced into microstructures intentionally to induce grain refinement and restrict grain growth.…”

The dry sliding wear behavior of extruded Mg-2Dy-0.5Zn alloy (at.%) was investigated using a pin-on-disk configuration. The friction coefficient and wear rate were measured within a load range 20e760 N at a sliding velocity of 0.785 m/s. Microstructure and wear surface of alloy were examined using scanning electron microscopy. The mechanical properties of alloy were tested at room and elevated temperatures. Five wear mechanisms, namely abrasion, oxidation, delamination, thermal softening and melting dominated the whole wear behavior with increasing applied load. The extruded Mg-2Dy-0.5Zn alloy exhibited the better wear resistance as compared with as-cast Mg 97 Zn 1 Y 2 alloy under the given conditions through contact surface temperature analysis. The improved wear resistance was mainly related to fine grain size, good thermal stability of long period stacking order (LPSO) phase and excellent higher-temperature mechanical properties.
