“…APS has been the most commonly used thermal spray technology to deposit these materials due to their high melting temperature [164,165,167]. Numerous studies have been carried out to investigate the mechanical and wear resistant property of plasma sprayed ceramic oxides [164,[172][173][174][175][176][177][178][179][180][181][182][183][184].…”

Gray cast iron (GCI) is a popular automotive brake disc material by virtue of its high melting point as well as excellent heat storage and damping capability. GCI is also attractive because of its good castability and machinability, combined with its cost-effectiveness. Although several lightweight alloys have been explored as alternatives in an attempt to achieve weight reduction, their widespread use has been limited by low melting point and high inherent costs. Therefore, GCI is still the preferred material for brake discs due to its robust performance. However, poor corrosion resistance and excessive wear of brake disc material during service continue to be areas of concern, with the latter leading to brake emissions in the form of dust and particulate matter that have adverse effects on human health. With the exhaust emission norms becoming increasingly stringent, it is important to address the problem of brake disc wear without compromising the braking performance of the material. Surface treatment of GCI brake discs in the form of a suitable coating represents a promising solution to this problem. This paper reviews the different coating technologies and materials that have been traditionally used and examines the prospects of some emergent thermal spray technologies, along with the industrial implications of adopting them for brake disc applications.

“…In literature, the crack propagation, removal of transferred films, and splat delamination were reported as predominant wear mechanisms affecting the wear of oxide ceramic coatings [8][9][10]. Figure 4 shows the SEM images obtained from the wear tests performed under different loads with the Al 2 O 3 ball.…”

“…In the literature, it is reported that if the load reaches a critical level, lateral cracks will begin from the plastic deformation zone and then progress rapidly, causing brittle fracture resulting in the removal of the material [21]. Bagde et al studied on friction and wear behavior of the plasma-sprayed Cr 2 O 3 -25TiO 2 coating [8]. They stated that the increase in abrasive wear rates depending on the load was observed as grain pullout caused by fatigue induced microcracks at low loads and as delamination cracks and splat fractures at high loads.…”

“…Chromium oxide (Cr 2 O 3 ) coating is used as a protective coating material in many engineering applications due to its high resistance to wear, corrosion, and oxidation. However, its fracture toughness is relatively lower than some oxide-content ceramic coatings [8]. Therefore, Cr 2 O 3 spray powder is blended with relatively soft oxide ceramics to increase the toughness of the coating.…”

“…Where contrast between the metal matrix and pores is a challenge, various ways are used to improve the contrast such as surface replication, shadowing or impregnation of pores space with fluorescent resin. Moreover, non-conducting samples need coating with thin metallic coatings, for instance, the polymeric membranes [81]. For a comprehensive characterization of pore geometry, pore morphology and size distribution, quite a large number of samples and measurements are required.…”

Porosity and Its Significance in Plasma-Sprayed Coatings

et al. 2019

Porosity in plasma-sprayed coatings is vital for most engineering applications. Porosity has its merits and demerits depending on the functionality of the coating and the immediate working environment. Consequently, the formation mechanisms and development of porosity have been extensively explored to find out modes of controlling porosity in plasma-sprayed coatings. In this work, a comprehensive review of porosity on plasma-sprayed coatings is established. The formation and development of porosity on plasma-sprayed coatings are governed by set spraying parameters. Optimized set spraying parameters have been used to achieve the most favorable coatings with minimum defects. Even with the optimized set spraying parameters, defects like porosity still occur. Here, we discuss other ways that can be used to control porosity in plasma-sprayed coating with emphasis to atmospheric plasma-sprayed chromium oxide coatings. Techniques like multilayer coatings, nanostructured coatings, doping with rare earth elements, laser surface re-melting and a combination of the above methods have been suggested in adjusting porosity. The influences of porosity on microstructure, properties of plasma-sprayed coatings and the measurement methods of porosity have also been reviewed.
