Influence of Size on the Microstructure and Mechanical Properties of an AISI 304L Stainless Steel—A Comparison between Bulk and Fibers

In this study, a novel attempt was made to prevent corrosion on an EN8 medium carbon steel substrate by coating it with AISI 316 stainless steel using the friction surfacing method. The ram tensile test was conducted on the sample and maximum bond strength of 504MPa, with a minimum coating thickness of 3.06 mm, was obtained. Three peak values of 42.19, 43.12 and 49.07 were obtained by the X-ray diffraction technique. A salt spray test was conducted on the samples. Two different dark yellow and dark brown rusts were observed on the substrate after 50 and 250 hours of treatment respectively. It has been found that the stability of the coating in a corrosive environment is demonstrated by its capacity to resist corrosion during the period of immersion in the electrolyte at 70°, indicating a capacitive behaviour. However, the phase angle of exposure to electrolyte for the AISI316-EN8 system became more resistive (65°) than for EN8 (45). The coating thickness has been greatly influenced by process parameters such as traverse speed, axial load and rotational speed. Coating combinations of such materials improve the service life in marine and automobile applications.

The growing demand of energy storage device has attracted significant attention toward transition metal nitrides because of their remarkable mechanical, electronic, and catalytic applications. Here, sputtered chromium nitride thin films deposited on steel substrate have been used as a working electrode for supercapacitor application. The deposited columnar CrN thin films show (111) and (200) planes of cubic phase. The electrochemical properties of CrN working electrode exhibit high specific capacitance of 41.8 F/g at the scan rate of 5 mV/s with excellent capacitance retention up to 2000 cycles. The supercapacitive performance of the CrN films suggests the potential application for supercapacitors.

Superaustenitic stainless steels have become of growing interest in industrial and technological fields, but there is not a complete understanding on their fundamental properties and their performances. For this paper, AISI 904L superaustenitic samples were nitrided and carburized in order to study the expanded austenite stability under severe deuterium and helium ion bombardment. Surface treatments were conducted using pulsed plasma glow discharges in a low pressure atmosphere, and a dense plasma focus device was used to irradiate the samples. Characterization techniques used were focused ion beam/SEM, energy-dispersive X-ray spectroscopy, and grazing incidence X-ray diffraction. Our results showed in carburized samples lattice expansion growth with the time treatment, but in nitrided samples, an expanded austenite reduction with time treatment was observed due to the formation of nitride nanoagglomerates. Moreover, this ion impingement provoked surface melting and a severe collision cascade, and a damaged bead located under the craters composed solely of minor alloying atoms. Furthermore, nitrided samples were more stable following ion bombardment than the carburized ones. When helium ions were used, the loss of expansion (triggered by diffusion processes of N or C to deeper regions) was more pronounced in the expanded austenite, but when deuterium ions were used to bombard the sample, there was a crystallite development of stressed austenite, which provoked a diffraction peak arousal at 43.3 degrees.
