“…Conditions of heavy wear are clearly seen from the rate of weight loss. The recognized pattern is in agreement with that noted by Alpas and Zhang [32] who suggest that the wear rate increases gradually with the applied load in the mild wear region.…”

“…It has been found that the wear resitance behavior of unreinforced alloy is lower than that of composites. This improved behavior is a result of the hard ceramic material which protects the surface [30][31][32]. The results given in Figure 5 show that the weight loss decreases as the percentage of the nano SiC particles increases from 0.5% to 4.5%.…”

SummaryPure aluminum nanocomposite reinforced with silicon carbide was produced by powder metallurgy process. The mechanical behavior of this composite was modelled and experimentally investigated. Measurements of density, tensile properties, and hardness showed that the tensile strength and the porosity of composites increased with an increase in the amount of nanoparticles; however, aluminum ductility decreased. On the other hand, the elongation percentage remains constant with an increase in the percentage of nanoparticles. Wear resistance of composite samples was higher than that of aluminium alloy. In the current research, a technique based on Artificial Neural Network (ANN) and Finite Element Method (FEM) was applied for the prediction of mechanical properties. It was observed that prediction results obtained in this study are consistent with the real measurements performed on composites.

“…The reinforcement particles support the load, so as to lessen the touch area between the pin and counter disk surface, decrease the friction coefficient and can prevent the scratch and cut from the surface. 14,24) Similar results for aluminum alloy matrix composites have been reported by Bermudez et al 14,25) For all specimens, initially friction coefficients have a quick increase with sliding distance to an approximately steady range after about 50 m. This increase corresponds to an increase in apparent contact area, until full contact occurs across the full diameter of the pin.…”

AlMg alloys close to ¢-Al 3 Mg 2 intermetallic phase were processed by neutral gas coverage melting process of pure elemental Al and Mg with the composition of Al40 mass% Mg. Mechanical milling was applied in order to convert the pre-alloyed ingots to nanocrystalline or amorphous alloy. X-ray diffraction and transmission electron microscopy (TEM) tests were carried out to investigate the formation of Al 3 Mg 2 single phase nanoparticle. Having prepared the single phase intermetallic, it was added to the pre-alloyed matrix powder of Al4.5 mass% Cu, in different contents. The effect of the reinforcing agent on the microhardness and wear behavior of the nanocopmosites were studied thoroughly with the aid of press-sinter methodology and quantitative data recorders via pin-on-disk wear test. The results of microhardness tests revealed that the hardness of nanocomposites is significantly improved with increasing reinforcement content with in the matrix. The coexisted wear mechanisms, mainly delamination and abrasive, of the consolidated nanocopmosites were investigated through scanning electron microscopy (SEM) and TEM observations.

“…Therefore, the investigation of the tribological characteristics of engineering materials under dry sliding conditions is necessary. [22][23][24][25] Ma et al 26 researched the friction and wear behaviour of steel with bionic non-smooth surfaces under dry wear condition, and results showed that the bionic surface of testing samples had better wear resistance and provided stable friction coefficient to some extent. Sun et al 27 studied the sliding wear behavior of plasma nitrided layers produced in AISI 316 type austenitic stainless steel at high temperatures.…”

This paper presented a study of friction and wear on 9Cr18Mo when rubbed against other materials (steel-304, steel-440C, steel-GCr15 or silicon nitride ceramic ball) at high temperature conditions. Friction and wear tests were carried out with universal a friction and wear testing machine. The wear morphology was analyzed by a Nanovea three-dimensional profilometer and trinocular positive Gang metallurgical microscope. The Vickers hardness of 9Cr18Mo at different temperatures was tested by means of a high temperature vacuum hardometer. Results showed that the friction and wear on the contact surface of the 9Cr18Mo sample are higher when the hardness of counter materials is higher than or similar to that of the sample. Under dry sliding conditions, the 9Cr18Mo sample surface presented various degrees of adhesion, plowing and pit, particularly if tested in the presence of a high temperature environment. During the worn stages, the counter materials on the worn surface successively produced cracks, crack growth, and wear debris under the action of load. Moreover, the frictional pair 9Cr18Mo-ceramic showed good anti-wear behavior at 400 °C that proved the anti high temperature performance of 9Cr18Mo.
