Macroscale to Nanoscale Tribology of Magnesium-Based Alloys: A Review

Tribological aspects of magnesium matrix composites: A review of recent experimental studies

“…The most important parameters affecting the tribological behaviour of Mg matrix composites are reinforcement content, reinforcement type, reinforcement size, applied load, sliding speed, sliding distance and temperature [9,14,18,84]. A detailed analysis of these factors is imperative to understand the wear behaviour of Mg matrix composites.…”

“…Mg alloys have many advantages, such as high stiffness, good damping ability, superior biocompatibility, recyclability, machinability and huge hydrogen storage capacity [5][6][7][8]. Nevertheless, the widespread use of Mg alloys is limited due to their poor formability, low corrosion resistance and poor wear properties [9][10][11][12]. It is well known that the friction response of systems in contact with sliding parts is of great importance regarding energy efficiency and service life [9].…”

It is well known that the friction response of systems in contact with sliding parts is of great importance regarding energy efficiency and service life [9]. For this reason, it is imperative to improve wear performance for the use of Mg alloys in parts that require wear resistance, such as brakes, gears and piston-cylinder assembly [13].…”

“…The poor wear resistance of Mg is attributed to its low strength, low hardness and limited work hardening [9,14]. Researchers are interested in alloying [9,15], coatings [12,16,17] and composite material production [18][19][20][21][22] to improve the wear performance of Mg alloys. Researchers generally prefer particulate reinforcements in producing Mg matrix composites due to their isotropic nature, low costs and processing advantages.…”
