“…8c), it could be observed that there were small particles that appeared bright at the SEM. By EDX it has been determined that they correspond with Fe from the counterbody, forming a new tribolayer usually named mechanically mixed layer (MML), also observed previously in these Al/SiCp coatings in other works [23,27]. In this zone, subsurface cracking responsible of the delamination of the material has been observed (arrowed zones).…”

This chapter discusses the concepts, casting techniques and applications of functionally graded materials metal matrix composites (FGMMCs). Considerations were given to bulk functionally graded aluminium matrix composites (FGAACs) production processes. Liquid-metal forging processes of FGAACs fabrication, such as infiltration process, squeeze casting, friction casting or compocasting, stir, and centrifugal casting were discussed. The chapter provides basic concepts of the processes and overview of their processing parameters, such as mould rotational speed; reinforcement particles size and volume; degassing method; melting and pouring temperatures; pressure; and stirrer. The study notes that functionally graded materials (FGMs) are commonly used in automotive, aircraft, aviation, chemical, medical, engineering, renewable energy, nuclear energy, and optics electronics industries.

“…The variation of sliding velocity is complex because the mechanism of wear include deformation and interfacial components, transfer also play an important role. For these reasons, no unique trend between wear rate and sliding velocity is to be expected and experiments show, that wear rate/sliding velocity relationships exhibiting maxima, minima or little variation can all be obtained, depending on the materials involved and the precise conditions of sliding imposed [22][23][24][25][26][27][28][29][30].…”

The present work illustrated the effect of three types of oil-dispersed polymers; low-density polyethylene (LDPE), high-density polyethylene (HDPE) and Polysulphide rubber (PSR) on the abrasive sliding wear of stainless steel. Both friction coefficient and wear scar diameter obtained at various applied external voltage, and polymers weight percentage at 0.5 m/s sliding velocity, 20°C and 5N applied load. The samples immersed in H 2 SO 4 medium at test period ranges from 10 to 50 days. The effect of the corrosion medium carried out and investigated at various values of the external voltages. The wear resistance related to the total mass loss measured and the worn surfaces analyzed by optical microscope. The application of external voltage increases both friction coefficient and wear scar diameter. At various applied external voltage and polymer contents, the wear scar diameter and friction coefficient trends of PSR has a lower values followed by both LDPE and HDPE trends respectively. Negative applied voltage has lower scar diameter while positive voltages has lower friction coefficients except at -4 Volt.
