“…8.22. This type of trend has been observed in Al-Fe composite [32], Mg alloy matrix hybrid composite reinforced by Saffil short fibers (diameter 3-8 μm and length 200 μm) and SiC particles (40 μm) [61], AZ91D-0.8 % Ce alloy matrix hybrid composite reinforced by Al 2 O 3 short fibers and graphite [86], and Cu/WC composites [97]. In addition to the increase of wear [36] rate with increasing normal load, the wear mechanism of the composites changes with normal loads.…”

Metal matrix composites (MMCs) are an important class of engineering materials that are increasingly replacing a number of conventional materials in the automotive, aerospace, marine, and sports industries due to their lightweight and superior mechanical properties. In MMCs, nonmetallic materials are embedded into the metals or the alloys as reinforcements to obtain a novel material with attractive engineering properties, such as improved ultimate tensile strength, ductility, toughness, and tribological behavior. In this chapter, an attempt has been made to summarize the tribological performance of various MMCs as a function of several relevant parameters. These parameters include material parameters (size, shape, volume fraction, and type of the reinforcements), mechanical parameters (normal load and sliding speed), and physical parameters (temperature and the environment). In general, it was shown that the wear resistance and friction coefficient of MMCs are improved by increasing the volume fraction of the reinforcements. As the normal load and sliding speed increase, the wear rate of the composites increases and the friction coefficient of the composites decreases. The wear rate and friction coefficient decrease with increasing temperature up to a critical temperature, and thereafter both wear rate and friction coefficient increase with increasing temperature. The nano-composites showed best friction and wear performance when compared to micro-composites.

“…The use of various particulates to reinforce the material has been investigated in numerous publications. Carbides, borides and metal oxides are most widely used for reinforcement due to their high hardness and wear properties, particularly TiC (Akhtar et al [3]), WC (Deshpande and Lin [4]), SiC (Tjong and Lau [5]), TiB 2 (Tjong and Lau [6] and Tu et al [7]), Al 2 O 3 (Das et al [8] and Dyachkova and Feldshtein [9]). …”

In the paper, the changes in some mechanical properties and wear behavior of CuSn10 sintered bronze and MMCs based on this bronze reinforced with composite ultrafine aluminide powders FeAl/15 % Al 2 O 3 , NiAl/15 % Al 2 O 3 and Ti-46Al-8Cr are described. It was observed that the presence of aluminides in the MMCs leads to an increase in the hardness, but the flexural strength may increase or decrease depending on the type of aluminide. The presence of aluminides in the MMC reduces the wear rate considerably. It is decreased in the direction of FeAl/15 % Al 2 O 3  NiAl/15 % Al 2 O 3  Ti-46Al-8Cr aluminides and for the best MMC composition the advantage is about 20 times. In the MMCs wear process, micro-craters are formed on the contact surface and it is the principal reason of a decrease in the wear rate.

In this work infiltration behavior of mechanical alloyed 75 wt% Cu -25 wt% WC powders into porous WC compacts were studied. Owing to their ductile nature, initial Cu powders were directly added to mechanical alloying batch. On the other hand initial WC powders were high energy milled prior to mechanical alloying. Contact infiltration method was selected for densification and compacts prepared from processed powders were infiltrated into porous WC bodies. After infiltration, samples were characterized via X-Ray diffraction studies and microstructural evaluation of the samples was carried out via scanning electron microscopy observations. Based on the lack of solubility between WC and Cu it was possible to keep fine WC particles in Cu melt since solution reprecipitation controlled densification is hindered. Also microstructural characterizations via scanning electron microscopy confirmed that the transport of fine WC fraction from infiltrant to porous WC skeleton can be carried out via Cu melt flow during infiltration.
