“…Five temperature levels were used, from room temperature to 570°C, as shown in Table 3. The amount of material removal was calculated from the difference in mass of the pins before and after the tests, using Precisa XB 220 A balance with an accuracy of 0.0001 g. Volumetric wear was calculated by subtracting the mass of the pin before and after testing and dividing it by the density of the stainless steel, (Parthasarathi and Duraiselvam, 2010).…”

“…They found that the wear increased from room temperature to 350°C and then decreased significantly up to 650°C, due to the formation of different types of oxides. Parthasarathi (Parthasarathi and Duraiselvam, 2010) studied the wear rate of austenitic stainless steel at high temperatures and claimed that the oxide layer began to form at 350°C and more, which protected the surface from the wear. Kennedy (Kennedy, Lu and Baker, 2015) studied the temperature of contact surfaces and proved that the temperature arises in sliding contact surfaces and is the summation of the ambient temperature, the temperature rise due to friction, and the flash temperature that occurs at the localized contact points.…”

Due to the relatively high wear rate of the austenitic stainless steel S30400 and the high mechanical properties of the super austenitic stainless steel S31254, it was possible to compare the wear behavior of the two alloys and select the best alloy to extend the service life of sliding parts. In this work, wear tests were performed at five different temperatures (30°C, 140°, 300°C, 460°C, and 570°C) at constant sliding speed, applied load, and sliding distance for both alloys. The specific wear rate of S31254 was more than 50% lower compared to S30400 at the different temperatures, except at 570°C, where it was only 16%. According to scanning electron microscopy and X-ray diffraction, oxide formation on the worn surfaces started at 300°C and increased with increasing temperature. The oxide layers protected the surface and reduced wear and material removal. Overall, S31254 exhibited better wear resistance at various temperatures.

“…By using these techniques, the amorphous coatings are prepared by melting the feedstock particles into droplets, impinging the droplets onto a cold substrate and forming the coatings by rapid solidification in situ. Previous works have reported that NiCrBSi-based thermally sprayed coatings containing amorphous structures exhibit high hardness and wear-corrosion resistance [18,19]. Planche et al compared the characteristics of the NiCrBSi coatings sprayed by using plasma, flame and HVOF processes [20].…”

Microstructural Charactistics of Plasma Sprayed NiCrBSi Coatings and Their Wear and Corrosion Behaviors

Nickel-based alloys are commonly used as protective coating materials for surface protection applications owing to their superior resistance to corrosion, wear and high-temperature oxidation. It is urgent to study the fundamental mechanism between the structure and corrosion properties of the Nickel-base composite coatings. This paper, therefore, focuses on clarifying the mechanisms of the microstructure influencing the acid corrosion and mechanical characteristics of the as-sprayed NiCrBSi coating and post-heat-treated coating. The formation mechanisms of the amorphous phase of flat particles during the plasma spray process were studied by using X-ray diffraction analysis, Raman spectroscopy and confocal laser scanning microscope at first. Then the evolutionary process of the corrosion structure and phase of the coating in the accelerated corrosion experiment is directly visualized by using scanning electron microscopy and energy spectrum analysis. The mechanical properties of the amorphous NiCrBSi coatings are lastly measured by microhardness and friction wear tests. The critical phenomena and results help to elucidate the relative influence of the surface features of atmospheric plasma sprayed coatings on acid corrosion responses and wear resistance, aiming at contributing to the development of a protective technique for electrical engineering.

Coatings have been used widely to improve the wear resistance of the stainless steels [13][14][15][16][17][18][19][20][21]. Parthasarathiet.…”

“…al. [14] have used plasma sprayed NiCrBSiCFe coatings and established that the wear performance of AISI 316 has increasedby almost 4-5 times as compared to the bare substrate. In another study, the Cr-C-O composite coatings were developed on AISI 304 stainless steel by using cathodic vacuum arc deposition (CVAD) technique.…”

Present manuscript deals with the sliding wear behaviour of SS- 304 and SS-316 with and without oxidation prior to wear test. The dry sliding wear performance of the steel samples was noted in as received conditions and then after oxidizing the sample at 600°C for 6 hours. The variations in hardness of both the steels before and after oxidation were estimated. The dry sliding wear tests were carried out using pin on disk technique at different sliding velocity and different loads, by using hardened steels counter surface. The worn surfaces were characterised by using FE-SEM/EDS analysis to ascertain the mechanism of wear in the samples. From various characterisation results and observations of volume loss, the effect of prior oxidation was analysed for the both stainless steels. It has been found that the oxidation leads to the formation of some protective oxides which leads to increase in the hardness of the samples due to which the wear performance was improved compared to the as received alloys.
