“…However, in some cases, the use of sliding contact bearing cannot be replaced by another bearing because they have their specific benefits and are frequently in use [5]. Journal bearings are employed in industrial machineries, engines, automobile industries, turbines (steam, hydraulic and gas), electric generators, compressors and/or other machineries of oil and petrochemical industries [6]. The research trend is to replace the most widely used conventional bearing materials with novel materials that have superior properties in respect to the conventional bearing materials [7].…”

Composite materials are unique because reveal great physical, mechanical and thermal properties. However, there is yet huge potential to enhance their features by adding specific reinforcement in the matrix in order to reach the requirements of a particular application. This paper presents detailed research on the impact of marble dust reinforcement to mechanical and tribological features of copper based metal alloy (C93200 series) composites dedicated for bearing applications. The novel composites made with marble dust reinforcement (1.5 to 6.0 wt%) were manufactured using the liquid metal stir casting technique. A micro-hardness tester and universal testing machine (Instron-5967) were used to obtain the mechanical properties. While, the POD tribometer was engaged to detect the wear features by simulating various operating conditions by setting the temperature constant (35°C). The Scanning Electron Microscope (SEM) was used to investigate the wear mechanisms produced at the hard contact between the composites with different marble content against an EN-31 hardened steel disc. The data gathered in this research proves an improvement in the mechanical properties, especially for a higher reinforcement ratio of novel composite, in respect to the matrix alloy. Furthermore, the novel marble dust reinforced composites reveal much better wear resistance in respect to un-reinforced composite that make it suitable for bearing application.

“…Physical simulation is done by laboratory test models (also defined as physical simulation models) with a wide band of measurement possibilities and input parameter settings. Fundamental model test systems [6] compete with application-near journal bearing rigs [7,8]. A compromise in terms of result transfer and efficiency can be achieved by using an application-near tribometer test methodology [9].…”

Assessment of Shaft Surface Structures on the Tribological Behavior of Journal Bearings by Physical and Virtual Simulation

Optimizing the surface topography of cast iron crankshafts offers the opportunity to use this material as an alternative to steel in high-performance combustion engines. In the past, this was not possible due to the higher wear on bearing shells and the higher friction losses in relation to forged steel shafts. In order to find an optimized shaft micro topography, the friction and wear behavior of steel and cast iron shafts with different surface treatments were compared to each other, using a combined physical (experimental) and a virtual (computational) simulation approach. The experiments were carried out with a rotary tribometer using a journal bearing test configuration with the possibility to test real-life bearing shells and shaft specimens, manufactured from real-life crankshafts. In the experiments, a polished steel shaft with low bearing wear was effective. The optimization of cast iron crankshafts by a novel surface treatment showed a significant reduction of bearing wear in relation to the classical surface finishing procedures of cast iron shafts. A computational simulation approach, considering the real-life micro topography by using the Navier–Stokes equations for the calculation of micro hydrodynamics, supports the assessment of fluid friction. The virtual simulation shows, in accordance to the experimental results, only a minor influence of the investigated shaft topographies on the fluid friction. Further optimization of shaft surfaces for journal bearing systems seems possible only by the usage of patterned micro topographies.

“…Antifriction aluminum alloys have been developed for replacement of antifriction bronzes in journal bearings [4]. Basically, developments of antifriction aluminum alloys aim at increasing the lead and tin contents in the alloys [9][10][11][12]. However, mechanical properties of the alloys could be worsened in that case [13].…”

The paper investigates the relationship between the tribological properties/compositions of new aluminum antifriction alloys and compositions of the secondary structures formed on their friction surfaces. Eight alloys with various compositions have been analyzed. The elemental compositions of the secondary structures on their friction surfaces have been determined. The relationship between the alloy secondary structure compositions with wear rate has been found. An attempt has been made to determine the secondary structure composition patterns based on the non-equilibrium thermodynamics and self-organization theory.
