“…The increase in weight percentage of TiC declines the wear of the composite and TiC resists the wear because the hardness of the TiC is higher than the counterpart and matrix material of the composite. The TiC sliding over the surface and change the nature of along with the carbide layer over the surface [20].…”

Typically Aluminum 6063 matrix composites have an extensive wear resistance application due to its high specific strength. Here the stir casting fabricated composites having 0, 3, 6 and 9 wt% of titanium carbide (TiC) are tested using a pin on disc sliding wear test equipment. Loads (P), speed (sliding and rotation) and sliding distance (D) are the input parameters. The improvement in hardness was observed when TiC content increases due to the homogeneous dispersion strengthening mechanism. The incorporation of TiC in the AA6063 matrix reduces the rate of wear (WR) and increases the resistance to wear. The "COF" reduces when the TiC composition increases. The "WR" and COF increase when 'D' and 'P' increases for all the compositions tested.

“…AMCs are manufactured with the continuous addition of fibre, short fibre and particle reinforcements. In many studies related to AMCs, it is reported that carbides [6][7][8], nitrides [9] and oxides [10,11] are used as reinforcement agent. Particle reinforced AMCs are commonly used owing to their availability, low costs, mechanical properties and variety of production methods [12][13][14].…”

“…Furthermore, mechanical alloying (MA), which is a powder metallurgy method, is preferred in the production of AMCs with better mechanical properties when compared to the other particle reinforced composite production methods [16]. In many studies, it was reported that reinforcement materials such as Al2O3 [11,15,18] and SiC [6,16,23,25] improved the wear resistance of AMC materials. Zirconia (ZrO2) is considered as a good reinforcement material in AMC materials owing to its high hardness and high elasticity module.…”

Due to the many advantages it provides metal matrix composite materials, it is used as a publication in many industrial applications, especially in the automotive industry. Therefore, it is necessary to know the properties of these materials such as mechanical, tribological and corrosion. In this study, the effect of different sliding speeds was investigated on wear behavior of aluminum matrix composite materials produced by adding different amounts of ZrO2 by mechanical alloying method. 4 different amounts (3%, 6%, 9% and 12%) ZrO2 were added to the aluminum 2% graphite matrix. Composite powders mechanically alloyed for 60 minutes, were produced green compact samples by cold pressed with a pressure of 700 MPa. The green compacts produced were sintered for 2 hours at 600 °C. The produced aluminum composites were characterized by microstructure, density and hardness measurements. Wear tests were carried out on a block onring type wear testing device, under 20 N load and three different sliding speed (0.2 ms-1 , 0.4 ms-1 and 0.6 ms-1) and three different sliding distances (53 m, 72 m and 94 m). As a result of the studies, hardness and density values increased as the amount of ZrO2 in the matrix increased. Wear test results showed that weight loss decreased with increasing amount of reinforcement in the matrix.

“…The composite material has the advantages of small particle size, good interface combination, no pollution on the particle surface and not easy to produce brittleness [19][20][21]. The size and distribution uniformity of the reinforced particles play an important role in improving the mechanical properties and friction and wear properties of the composite, so it is very important to control the distribution of the reinforced particles in the solidified structure [22][23][24][25]. In this paper, the reinforcement phase A1 3 Zr was produced by in-situ reaction method, and the (A356+A1 3 Zr) composite was prepared by fully reacting K 2 ZrF 6 with A356 melt under mechanical agitation.…”

A1 3 Zr/A356 Composite was prepared by in-situ reaction of K 2 ZrF 6 powder and cast aluminum A356 melt at different temperatures (710°C, 750°C, 770°C, 790°C). The effect of different melting temperature on the morphology of Al 3 Zr particles was studied, and the sliding friction and wear properties of the composites were studied by wear test. It can be seen from the x-ray diffractometer (XRD) that the prepared composite material consists of A1 3 Zr and ɑ-Al, and also has a small part of the aluminum-silicon eutectic phase; SEM analysis shows that the particles of in-situ reinforced phase are fine, With the increase of temperature, the morphology of A1 3 Zr reinforced phase changed from block to needle and strip, and the particle distribution of the reinforced phase was uniform and well dispersed in the matrix at 750°C. TEM experiments show that the reinforced phase exists at 750°C and has a good combination with the matrix, which plays a very good role in particle reinforcement Friction and wear experiments show that the different preparation temperature results in different phase morphology. The reinforced phase particles existing on the surface of composites at 710°C and 750°C bear most of the friction, so the friction coefficient of the composites is larger at these preparation temperature, and the main wear modes are oxidation wear and abrasive wear. The friction coefficient of the composites prepared at 770°C and 790°C is small, and the wear modes are mainly delamination wear and oxidation wear. When the preparation temperature is 750°C, the wear resistance of the composites is the best.
