“…This is due to the polarization of the reinforcement phase during MA by refining to nano size. Similar results have been obtained in some previous studies (Khorramie et al , 2012; Sekar et al , 2018). This reduction of the size of the reinforcement phase down to nanoscale is also evident from SEM images of AMC materials added 3%, 6% and 9% ZrO 2 .…”

Purpose The purpose of this study, the tribological behaviors at different temperatures of aluminium matrix composites (AMCs) with different amounts of ZrO2 added were investigated. Design/methodology/approach Aluminium graphite (A356/2 wt% graphite (solid lubricant)) composite powders prepared by adding four different amounts (3 wt%, 6 wt%, 9 wt% and 12 wt%) of Zirconia (ZrO2) to the matrix were mechanically alloyed for 4 h. Wear tests were conducted at five different temperatures (20 °C, 100 °C, 180 °C, 260 °C and 340 °C) and for three different sliding distances (53 m, 72 m and 94 m) on the pin-on-disc type wear tester. Findings Results of the study showed that the highest hardness and density value were measured for 12% ZrO2 added AMC material. Wear test results showed that weight loss increases with increasing temperature; weight loss decreases at all temperatures with the increasing amount of reinforcement in the matrix. Originality/value In this paper, the tribological properties of aluminium matrix composites produced by the mechanical alloying method by adding different amounts of ZrO2 were determined by simulating the tribological properties at different loads and temperatures.

Among the various types of manufacturing process methods for discontinuous metal matrix composite, stir casting is the best suitable manufacturing process to fabricate particulate reinforced metal matrix composite. Its benefit is its simplicity, durability, and adaptability. The main issue in this process is proper wetting of reinforcement in aluminium matrix material. Only proper wetting results in a homogeneous dispersion of reinforcement material, and these homogeneous dispersions help to improve the properties of metal matrix composite material. The purpose of this paper was to discuss the outline of the stir casting process, process parameters, and the contribution effect of process parameters. This paper also presents about of the conditions should follow during the addition of reinforcement material and matrix material pouring in mould cavity. This paper also discusses the conditions that must be met during the addition of reinforcement material and matrix material pouring in the mould cavity. This paper also looked into the impact and contribution of stirring casting time, speed, and temperature in aluminium metal matrix composites, as well as processing issues in aluminium metal matrix composites, challenges, and research opportunities.

“…Also, the SEM images show that ZrO2 added into the matrix (light grey areas, 4. location) are particularly located on the grain boundaries. Sekar et al [34] and Baghchesara et al [27] stated in their studies that ZrO2 tended to agglomerate on the grain boundaries. XRD analysis results of composite materials after the addition of AlGr and 12% ZrO2 are given in Figure 2.…”

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.
