“…The letter ÔMÕ in A380M indicates higher manganese content. High silicon content helps to increase fluidity and improves corrosion resistance (Ref [11][12][13]. Furthermore, the presence of silicon as an alloying element in these alloys improves wear resistance significantly.…”

Due to their excellent strength to weight ratio, aluminum alloys are widely used in a variety of automotive components. Their relatively low melting point and low hardness compared to other engineering alloys, however, limits their use in applications where wear resistance is needed. To improve the wear resistance of these alloys, a good understanding of their wear behavior is essential. Dry sliding wear behavior of A380M aluminum alloy was investigated in the load range 6-20 N against steel ball using a reciprocating ball-on-flat configuration and at a frequency range of 4-20 Hz. Micromechanical properties were measured using a nano-indentation system. Scanning electron microscope examination of the wear track and debris revealed that wear within the present load and frequency range was due to abrasion, plastic deformation, and delamination. It was found that the wear rate of A380M aluminum alloy increased with load and decreased with increase in frequency.

“…A deterioration in wear properties of Al-Si alloys with increasing Si content, starting both at eutectic point and at relatively higher Si levels is reported in [ 6]. The wear properties in terms of Si content has been a subject of great controversy over the years [6][7][8][9][10][11]. It is suspected that the role of Si particles may be different in thixoformed Al-Si based alloys from that in conventional cast grades.…”

Aluminum alloys are attractive for critical applications such as pistons, clutch housings and liners in automotive industry for their high strength to weight ratio, high corrosion resistance and good heat conductivity. These alloys can be fabricated using casting and powder metallurgy techniques in which porosity is a common feature. The presences of pores adversely affect the mechanical properties and wear resistance of these components. Not only the total area percentage of porosity influences the degradation in properties but also size, shape and interconnectivity of pores play an important role. In this study, aluminum alloys were produced using powder metallurgy technique. The amount of porosity was varied by varying compaction pressure and amount of wax added before compaction. Reciprocating wear tests (ball-on-flat configuration) were performed against AISI 52100 bearing steel ball under both low (1.5-5N) and high (6-20N) loads. Scanning electron microscopy was employed in order to identify possible wear mechanisms. Both detrimental and beneficial effects of porosity under different loading conditions were observed. An attempt has been made to develop a relationship between pore size and distribution and wear behavior of aluminum alloys.
