“…The results of SRIM simulation showed that the irradiation depth of 400 keV C + and 200 keV He + on SiC coating was less than 1µm, it is difficult to obtain the hardness value by common hardness testing methods. In the past few decades, the nanoindentation test has been proved to be a simple and effective method to analyze the mechanical properties of ion irradiated materials [70][71][72]. Due to the surface effect of the sample, the hardness values within the range of 0-200 nm depth had a large deviation and should be abandoned.…”

The microstructure and nanoindentation hardness of unirradiated, irradiated, annealed and corroded SiC coatings were characterized. Irradiation of 400 keV C+ and 200 keV He+ with approximately 10 dpa did not cause obvious amorphous transformation to nanocrystal SiC coatings and induced helium bubbles with 2–3 nm dimension distributed uniformly in the SiC matrix. High temperature annealing resulted in the transformation of SiC nanocrystals into columnar crystals in the irradiated region. Line-shaped bubble bands formed at the columnar crystal boundaries and their stacking fault planes and made the formation of microcracks of hundreds of nanometers in length. Meanwhile, some isolated helium bubbles distributed in SiC grains still maintained a size of 2–3 nm, despite annealing at 1200 °C for 5 h. The SiC coating showed excellent corrosion resistance under high-temperature, high-pressure water. The weight of the sample decreased with the increase of corrosion time. The nanoindentation hardness and the elastic modulus increased significantly with C+ and He+ irradiation, while their values decreased with high-temperature annealing. An increase in the annealing temperature led to an increased reduction in the values. Corrosion caused the decrease of nanoindentation hardness and the elastic modulus in the whole test depth range, whether the samples were irradiated or unirradiated.

Metal cutting operations involve intense heat generation owing to plastic deformation of the work piece and due to friction at the tool-work piece and tool-chip interface. The heat generated in metal cutting unfavourably affects the quality and thus the functional performance of the product. It is known that quality and functional performance is the function of roughness and dimensional accuracy. To maintain a longer component life, along with the robust material choice, a component should have good surface finish and dimensional accuracy. While, for the organization to monitor and control their environmental issues in a holistic manner, emphasis in adopting eco-friendly practices and protecting environment has been growing continuously across all the business sectors. In this study, an attempt is made to optimize the process parameter of stainless steel AISI-410 alloy, a nuclear graded material, for better surface finish. For this, Taguchi L9 orthogonal array was utilise to identify the process parameter and cutting environment. Analysis of variance (ANOVA) was also conducted to highlight the significant parameter that affects the surface finish most. A statistical model to forecast the surface roughness was also developed and was validated by an experiment with a maximum error of 12%. Results indicates that feed rate is the most critical factor that effects the surface roughness with the contribution of 91.5%, followed by environment with 5.22% contribution, cutting speed and depth of cut with 2.7 % and 0.4 % respectively. The correlation coefficient of 0.9213 and conformation tests reveals that developed statistical model predicts surface roughness with the statistical error limit.

“…The improved corrosion resistance is derived from the incorporation of 12% chromium even though an approximate proportion of 18% is reported in mostly used grades. This has tremendously increased their usage in most structural and other engineering-related applications [11,12]. This steel grade has been reportedly used in impellers tools, pressure vessels, and pump gates due to its wear and corrosion resistance [13].…”

This study investigates the microstructural, nanomechanical, and corrosion behaviour of different sections of 410 steel fabricated via directed energy deposition technique. The morphology exhibited by the longitudinal and transverse sections of the specimens was examined under a scanning electron microscope (SEM), while micro-computed tomography technique (micro-CT) was used for examination of the internal structure of the specimens. Nanomechanical properties were assessed using a nanoindenter, while potentiodynamic polarization technique was adopted to investigate the corrosion resistance of the specimens in a chloride environment. The SEM micrographs revealed minimal pores in the specimens which confirmed the improved density in the layer-by-layer built specimen. Micro-CT images confirmed the presence of tiny pores in the specimens sectioned from the top layer of the 410 stainless steel rod in comparison with the middle- and bottom-sectioned specimens. The corrosion and post-corrosion analyses confirmed that the top specimen exhibits the least corrosion resistance in comparison with the other specimens.
