“…For highly corrosive environments like boiling nitric acid, the equipment made of SS 304L may not be suitable because the latter is prone to extensive intergranular corrosion and end grain corrosion due to the Cr pres- ent in the alloy [27,28]. But it is estimated that the equipment made of SS 304L can be used as a temporary storage for low and medium level acidic radioactive waste for a period of up to 30 years [29].…”

Centrifugal sedimentation, a well-known solid-liquid separation process, is typically used for the separation of solids from low concentration feeds because of its high separation efficiency due to high settling velocities. The performance of the tubular bowl centrifuge (TBC) can be studied by using the sigma theory, which assumes plug flow and rigid body motion inside the rotating bowl wall. The separation efficiency of the system is evaluated by determining the effective fluid layer thickness from the experimental data. A method suitable for evaluating the separation efficiency at different parameters for a given TBC is explained along with experimental validation. By using this method, different case studies are performed which depict the influence of each parameter on the separation efficiency. Also, it is demonstrated that the same higher separation efficiency (98 %) at 20 000 rpm could be achieved at higher bowl capacities.

The paper presents the experimental study exploring the corrosion of carbon steel St3 samples in the presence of a microbiological community sampled at the Yeniseiskiy site and the microbiota of bentonite clays. Depending on the conditions, an average 3—30-fold increase in the corrosion rate of steel was observed due to the biogenic and biogenic-mediated processes. The maximum steel degradation effect was observed at a temperature of 50°C in the presence of sulfate ions under conditions being considered optimal for sulfate-reducing bacteria. The developed steel corrosion model was used to determine the activation energy of the aerobic and anaerobic corrosion process.

“…Its applications include dies for stamping, punches, mandrels and dies for wire drawing 1 . AISI 304 steel is of austenitic stainless steel group, characterized by high corrosion resistance which ensures its application in several industrial areas, with emphasis on food, biomedical, petrochemical and nuclear [2][3][4][5] . However, its poor tribological and mechanical properties and a significant tendency to adhesive wear limit its field of application 6,7 .…”

Influence of Hastelloy’s Cathodic Cage Plasma Deposition on Corrosion Resistance of AISI 304 Stainless Steel and of AISI D6 Tool Steel

AISI D6 tool steel and AISI 304 stainless steel are among the most widely used material in the industry. However, this application field can still be expanded through the coatings deposition. In this regard, the objective of this work was to evaluate the impact of coatings application by cathodic cage technique using Hastelloy's cathodic cage, on corrosion resistance of these steels. Two treatment temperatures were compared. The samples were characterized by Optical Microscopy, Scanning Electron Microscopy, Energy Dispersive Spectroscopy, X-Ray Diffraction with the application of the Rietveld routine and corrosion test. The results showed the formation of multiphase layers that contributed to corrosion potentials reduction for treatments at 400 °C, being more effective when applied on AISI D6. It was observed that the corrosion resistance is influenced by the temperature, which was attributed to the precipitation of chromium nitride and iron oxide at 450 ºC.
