“…After that, a Ø1 cm ZrO 2 ball was installed on the machine as a counterpart. To begin with, we performed a couple of test measurements, in which we set and changed the test parameters based on data found in the literature [46][47][48][49][50][51]. Based on these preliminary measurements, we selected the final measurement data (Table 3).…”

The A356 alloy is commonly used in the foundry industry to produce high-stressed automotive components, such as motor frames and cylinder heads. The aim of this work was to investigate how the mechanical and tribological properties of this alloy can be improved by applying an anodizing process. The properties of the oxide layer formed by anodizing using oxalic acid at low temperatures were characterized by different analytical and tribological methods. The combination of tribological methods with standard measurement techniques—such as hardness measurement, layer thickness measurement, as well as the analysis of the morphological characteristics—was used to track the layer evolution during wear developments.

“…The increase of graphite content on the friction material causes more graphite to be distributed on the friction surface. This condition can prevent adhesion and contribute to forming a friction layer on the friction interface [36][37]. The friction layers prevent the hard particles from sticking in the friction interface [35] and inhibit the micro-welding of metallic ingredients [38], thereby protecting the surface from excessive wear [12,39].…”

Friction modifiers play an important role in modifying the friction performances on the brake pad material. This study aims to determine the optimal friction modifier composition for obtaining a high friction coefficient (CoF) stability and low wear with the Taguchi method. Taguchi's L8 orthogonal array consists of five factors, and two levels were used to design and perform the experiment. The tribological properties (CoF stability and wear) were tested using the JF160 Chase friction tester according to the SAE J661 standard. According to the S/N ratio and ANOVA analysis, the controllable factor of h-BN has a significant effect on CoF stability. While graphite and h-BN have a dominant influence on wear.

“…The filler materials in the composite friction brake have several functions: to reduce production costs, to improve the manufacturing process, and to stabilise the friction coefficient [4,5]. The addition of fillers will lead to an increase in thermal conductivity, which will lower the wear rate during high temperatures in the contact area [6].…”

“…It is highly resistant to fatigue and wear, and has good chemical stability, oil resistance, and vibration absorption [12,13]. This polymer is commonly used as a stabiliser to increase the cross-link and to improve the wear resistance of composite friction brake materials containing asbestos fibres [4]. Ghosh et al [14] reported that NBR could modify phenolic resin and improve friction coefficient performance with the addition of graphite.…”

The aim of this research is to investigate the effect of nitrile butadiene rubber (NBR) as fillers on the mechanical and tribological properties of composite friction brake. Four compositions of specimens, having different NBR volume fractions (0, 4, 8, and 12 %), were manufactured. We assessed their mechanical properties by the three-point bending method according to ASTM D790 standard. We measured their tribological properties under various contact pressures and sliding speeds using a pin on disc tribometer. The results showed that NBR could improve the mechanical properties of composite friction brake materials, and the tribological properties such as wear resistance and friction coefficient increased with increasing NBR volume fraction.
