“…For the PoD test, 14400 m of total sliding distance, 2 m/s of sliding speed, and 0.6 MPa of applied pressure were considered. The selected PoD test conditions were intended to approximately simulate the mild wear condition, which is typical for braking systems [1,10,11,15]. The PoD test was also carried out on a GCI disc under identical testing conditions in order to provide a better reference point and an understanding of the coating properties comparatively.…”

“…For instance, carbonceramic composites have been established as an alternative to traditional brake disc materials since they display reduced wear rates and PM emission [7][8][9], However, because of the sophisticated production methods and unique features, these kinds of discs usually come with a higher price and for specific luxury cars. The application of coatings and disc surface treatments has also been investigated to reduce wear and PM emissions of brake discs [2,[10][11][12][13][14].…”

In this study, the potential of Fe3Al coating material as an environmentally friendly alternative to coatings containing critical elements for brake discs was investigated. A buffer layer of Cr-Mo steel (Ferro 55) was applied to enhance coating quality and prevent the formation of hot cracks during solidification. Microstructural analysis of the cross-section of the coating showed that the buffer layer diffused into the Fe3Al coating, forming a combination of Fe3Al, Fe, and Fe3AlC0.5 phases. The tribological properties of the Fe3Al coating were evaluated by pin-on-disc tests using two different copper-free friction materials extracted from commercial brake pads. The wear results showed a coefficient of friction comparable to that of an uncoated disc, but with a reduction in Particulate Matter (PM) emissions, an interesting aspect that is gaining increasing importance in view of the upcoming international standards..

“…Recent academic studies have highlighted the potential of reducing particulate matter emissions by enhancing the wear resistance of brake surfaces through heat treatments [5] or the application of wear-resistant coatings [6][7][8][9]. Coating has emerged as an efficient and effective method to address the issue of particulate matter emissions from braking systems.…”

Gray cast iron (GJL) is known for its excellent damping property and high thermal conductivity, thanks to its unique lamellar graphite and pearlite structure. In a recent study, laser metal deposition (LMD) was explored as a potential process to enhance the corrosion resistance and wear mechanism of this tribological system. The focus was on laser cladding of gray cast iron using two different of stainless-steel materials, namely 430L and 316L, combined with TiC and WC particles. To create the samples, a multilayer coating system was employed. A comparative analysis of the microstructures was performed to understand the interaction of the laser beam with the material (composite materials). Surface properties were then characterized using light microscopy and electron microscopy (SEM) before and after subjecting the samples to a shock corrosion test, simulating automotive conditions. Additionally, phase analyses were performed at the interfaces between the coatings and the substrate, with particular attention given to the behavior of the graphite lamellae at these interfaces. This study aims to provide valuable insights into the potential improvements that can be achieved through laser cladding on gray cast iron, specifically in terms of corrosion resistance and wear mechanisms. By analyzing the microstructures and surface properties, researchers can gain a better understanding of the performance and durability of the coated samples.

“…The research of surface coating technique, which reduces wear and improves service life and reliability of industrial equipment by preparing a protective coating on the contact surface, has aroused great interest [3][4][5]. Laser cladding [6], chemical/physical vapor deposition [7,8], plasma spraying [9] and electrodeposition [10] are all commonly used as surface coating techniques to enhance wear resistance of materials. Among these methods, the electrodeposition method has received much attention owing to its low cost, ease of implementation and applicability to various geometries [11][12][13][14][15].…”

Among the preparation methods of functional coatings, the electrodeposition technique has attracted much attention due to its advantages of economy, high efficiency and good structural adaptability. The application of aluminum alloy materials is greatly limited due to their poor friction reduction and wear resistance. Therefore, to enhance the tribological behaviors of aluminum alloy materials, the Ni-MoS2, Ni-SiC and Ni-MoS2/SiC composite coatings were prepared on the 2218 aluminum alloy by an electrodeposition technique. The prepared composite coating samples exhibited a compact and dense microstructure, which was consistent with the result of their high microhardness. No obvious microcracks and defects appeared at the interfaces, indicating that the composite coating samples had good adhesion to the substrates and can effectively improve the frictional shear resistance. The results of wear experiment showed that the wear rate, friction coefficient and friction response time of all composite coating samples were lower than that of the substrate sample. However, the friction reduction and wear resistance of the same composite coating sample were not consistent. The friction coefficient of the Ni-MoS2 composite coating sample was the lowest, and the wear rate of the Ni-SiC composite coating sample was the lowest. According to the worn surface observations, the wear mechanism of composite coating samples was mainly characterized by the mild abrasive wear, flake spalling, tearing and pits caused by particle shedding, and the substrate sample showed a severe adhesive wear and abrasive wear.
