“…Phosphor-coated samples, on the other hand, seem to have higher wear resistance than uncoated samples. In the studies, it has been stated that anodizing processes increase the wear resistance of the materials used as the substrate [3,23,36]. In the studies, the way of application of the anodic coating process, voltage application temperature, etc.…”

Anodic oxidation is used to improve the wear resistance and surface properties of aluminum alloys. In this study, the effect of two different anodic oxidation (hard anodizing and phosphoric coating) on the wear properties of 2017A aluminum alloy used as a model aircraft engine piston was investigated. In order to determine the effect of anodic oxidation, microhardness, friction coefficient, wear resistance, vibration, and worn surface images of the samples were evaluated. It was concluded that anodic oxidation significantly improved the hardness, friction coefficient, and wear resistance of the samples.

“…They observed that the anodizing process nearly tripled the wear resistance of AA7075-T6 and reduced the wear rate by about 4.3 times. Pires et al [23] In their research, they made two different coatings on SAE 305 aluminum alloy. The processes they apply are anodizing and diamond-like carbon coating, respectively.…”

“…Due to wear debris accumulation under certain load and speed, generally two conditions occurred. Either the foreign particles can be transformed into micro cutters or it may behave like rollers between two mating surfaces [53,54]. Therefore, the HT coating accumulated harder wear debris that can be characterized as micro rollers and decreased the contact pressure between two counter faces in HT coating [55].…”

“…Delaminated areas are seen from wear track morphologies of AP coatings. This certain delamination is caused by three-body abrasive wear mechanism during the process [53]. Eventually, the effects of the wear mechanism in these coating materials are directly linked to the hard wear debris and instead of the sliding phenomenon, transformed the scenario into a rolling abrasive nature for HT [63,64].…”

The Ni-P-B ternary coating was prepared on steel specimens through electroless deposition and their microstructural and tribo-mechanical properties were investigated. Heat treatment of the as plated coating was carried out at 390 °C to realize its effect on microstructural, mechanical, tribological properties of the coating. Microstructural analysis was carried out to study phase structure, morphology, topography, and coating compositions by using XRD, FESEM, AFM, and EDS. Contact angle measurement was also performed to evaluate the wetting behavior of the coatings. The as-plated coating exhibited hydrophobic character with a contact angle of∼96.7°, whereas the heat-treated coating resulted in hydrophilic character with a contact angle of∼79.5°. Mechanical and tribological properties were evaluated by using Vickers microhardness, nanoindentation, and dry sliding friction test. It is observed that the heat treatment process has an excellent impact on mechanical and tribological properties. Heat-treated ternary coating resulted in higher hardness (6 GPa) than asplated coating (5 GPa). Similarly, higher young's modulus was also achieved in the heat-treated coating (232 GPa) during nanoindentation experiments. Profound improvement in tribological performance is executed in both coatings over steel specimens. Maximum up to∼33% and∼45% decrement in COF is observed for as-plated and heat-treated Ni-P-B ternary coatings respectively. Due to greater hardness in heat-treated samples, the formation of the protective bilayer is observed along wear tracks as harder third particles created a strong adhesive bond by plastic deformation. The non-uniformity of the protective layer in the as-plated coating leads to higher COF and wear depth compared to heat-treated coating. Residual third particles behaved as micro cutters for as-plated coating while rolling effect is observed in case of heat-treated ternary coating.

In this study, the use of nickel fluoride tetrahydrate (NiF 2 •4H 2 O) as a surface activator and sealant at the same time for the coating of electroless nickel-phosphorus (Ni-P) on anodized aluminum alloy AA1050 is proposed. The usage of the activator resulted in more efficient deposition of Ni-P, improved adhesion properties, and increased wear and friction behavior as opposed to non-activated conditions. Scanning electron microscopy (SEM) and confocal laser microscopy (CLM) analyses of ultramicrotome-cut cross sections of Ni-P coated specimens, surface-activated by NiF 2 •4H 2 O, revealed a more well-structured metal-coating interface as opposed to non-activated conditions.
