“…At the same time, plasma electrolysis of carbon steel with added α-Al 2 O 3 in the electrolytic bath generated coatings with improved corrosion behavior [19]. Additionally, α-Al 2 O 3 -based coatings on carbon steel substrate prepared by plasma electrolytic oxidation increased the protection against wear and corrosion conditions [20].…”

“…In this regard, aluminum and aluminum-titanium oxide layers have been successfully prepared on pure Ti when surface hardening and corrosion protection was required [15,16]. Similarly, another approach is to develop and maximize α-Al 2 O 3 within the coatings with the aim of enhancing mechanical and corrosion properties of various alloys [17][18][19][20]. Ghafaripoor [17] reported that an increase of corrosion and tribocorrosion resistance occurred after PEO processing the Al alloy substrate in an electrolyte containing α-Al 2 O 3 particles.…”

In this study, the surface of commercially pure titanium (Cp-Ti) was covered by a 21–95 µm-thick aluminum oxide layer using plasma electrolytic oxidation. Coating characterization revealed the formation of nodular and granular α- and γ-Al2O3 phases with minor amounts of TiAl2O5 and Na2Ti4O9 which yielded a maximum 49.0 GPa hardness and 50 N adhesive critical load. The corrosion resistance behavior in 3.5 wt.% NaCl solution of all plasma electrolytic oxidation (PEO) coatings was found to be two orders of magnitude higher compared to bare Ti substrate.

“…This increases the rate of material removal by causing continuous delamination to occur on the surface of the specimen up until it begins to pull off from the pin surface (figure 11(b)). At longer sliding distances (1500 m), small amounts of delamination and wear debris are seen for TiC coating, primarily as a result of MML development on the surface of pin (figure 11(c)), a corresponding decline in the rate of material wear is seen in these circumstances [58]. Through continuous sliding, the dislocations occur on the surface at a certain distance.…”

In the present work, a low-carbon steel substrate was coated with Al2O3 and TiC using self-propagating high temperature synthesis. The synthesized coatings were annealed at 450oC for 2-6 hrs. The characteristics of the substrate, coated, and annealed samples were examined, including microhardness, wear resistance, and corrosion resistance. A pin-on-disc tribometer was employed to conduct the wear test by varying the load, sliding velocity, and distance. The impact of these factors on the wear rate and worn surface morphology was then examined. Further, corrosion resistance was evaluated using electrochemical corrosion testing with 3.5 wt.% NaCl as electrolyte. Results showed that Al2O3 and TiC specimens annealed at 450oC for 5 hrs and 4 hrs improved the microhardness by 1.3 and 1.06 times than that of as-coated specimens respectively. The synthesized Al2O3 and TiC coatings showed an abrasive wear mechanism at higher loads and tribolayer formation was observed at higher sliding velocity and distances. The corrosion and wear resistances of the samples were found as follows: substrate< Al2O3 coated < TiC coated < Al2O3 annealed < TiC annealed. The Al2O3 and TiC ceramic coatings were found to improve wear and corrosion resistance having potential applications in cement, petrochemical, and marine industries.

“…α-Al 2 O 3 is a high-temperature stable form of Al 2 O 3 , which is one of the important structural materials because of its low cost, low thermal conductivity, high hardness, high flexure strength, high dielectric strength, excellent chemical inertness, high wear resistance, and corrosion resistance. [1][2][3] These excellent properties make Al 2 O 3 coating have a high potential for broad applications in wear, corrosion, and dielectric protections. Atmospheric plasma spraying (APS) processes are performed at atmospheric pressure with high input power and plasma flame temperatures.…”

In this study, plasma sprayed Al2O3‐Cr2O3 coatings with different contents of graphene nanosheets were prepared for investigating effects of the graphene on microstructure, mechanical properties and wear behavior of the coating. The experimental results showed that graphene increased the porosity and the micro‐hardness of the coating. But excessive graphene decreased the micro‐hardness remarkably. Besides, the anti‐crack initiation and propagation abilities of the coatings with graphene improved significantly. The wear rate of the coatings decreased firstly and then increased with increasing the graphene content. Impressively, the wear rates of the coating with 2.9% graphene decreased by 33.5% and 36.7%, compared with those of the coating without graphene under normal loads of 5N and 15N, respectively. The main wear mechanisms of the coatings with and without graphene are brittle fracture and abrasive wear.This article is protected by copyright. All rights reserved
