Nanoparticles of titanium diboride (TiB2) coated with a conductive polymer and subjected to an oxidizing agent was carried out in this research. TiB2 nanoparticles coated with polypyrrole (PPy) were studied using XRD and TEM techniques. Nitrogen adsorption and desorption properties of nanoparticles are covered with modified polypyrrole to understand better the surface zone, structural features, and pore geometries of the nanoparticles. The water-based hazardous anionic Congo red (CR) dye was removed using polypyrrole-coated titanium diboride (PPy@TiB2) nanoparticles. Numerous cutting-edge experimental techniques, including FTIR, FE-SEM, EDXS, and element mapping analysis, were used to confirm the CR color’s adhesion to the PPy@TiB2 nanoadsorbent study. While conducting batch experiments, coated TiB2 nanoadsorbents with polypyrrole enhanced the adsorption behaviour. One of the factors evaluated in the adsorption tests was pH; another was contact time, and a third was dose. At pH = 4 , 98.75% of Congo red dye was detached using 60 mg of PPy-coated TiB2 nanoadsorbent. Several sorption-desorption cycles were performed on this nanoadsorbent to determine its reusability. An excellent adsorption capacity for water treatment is reported in PPy-coated TiB2 nanoadsorbent.

“…a. Friction coefficient results at room temperature [Figure 4(a)] show that the friction coefficient decreases with increasing sliding distance which is caused by the protective oxide layer formed on the surface and the graphite contained within the matrix acting as a solid lubricant effect (Simsek, 2019; Özyürek et al , 2014). However, the friction coefficient increases with increasing sliding distance in all samples at elevated temperatures.…”

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.

“…As the sliding speed increases, the increasing temperature resulting from friction leads to the formation of a more effective (protective) oxide layer on the surface. Due to the lubricating feature of the emerging oxide layer, the weight loss decreases [17,38]. On the other hand, the highest weight loss obtained at 0.4 ms -1 sliding speed can be explained with the breaking of the oxide layer forming on the surface.…”

“…Also, it is seen that the friction coefficient decreases along with increasing sliding distances at all sliding speeds. Accordingly, the friction coefficient decreases due to the protective oxide layer forming on the surface and also the solid lubricating effect of the graphite within the matrix [32,38]. On the other hand, it is expected that the friction coefficient decreases as the sliding speed increases.…”

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.
