Hydrogen embrittlement of nodular cast iron

Materials and Corrosion, Volume 72, Issue 1-2, Page 245-254, January 2021., 2021
Ferritic nodular cast iron, intended for use as the material for inserts of canisters for long‐term geological disposal of spent nuclear fuel, was studied for hydrogen sensitivity. Plastic deformation during hydrogen charging increases the hydrogen uptake considerably.

Sulphide‐induced stress corrosion cracking and hydrogen absorption of copper in deoxygenated water at 90°C

Materials and Corrosion, Volume 72, Issue 1-2, Page 317-332, January 2021., 2021
Stress corrosion cracking of oxygen‐free phosphorous‐alloyed copper was investigated in sulphide and chloride‐containing deoxygenated water at 90°C with sulphide concentrations of 0.001 and 0.00001 M. Several intergranular defects were found in the specimen exposed to the high sulphide environment.

Study on Deterioration Characteristics of Low‐Carbon Steel’s Mechanical Properties and Fracture Mechanism under Marine Engineering Environment

Advances in Civil Engineering, Volume 2021, Issue 1, 2021., 2021
In order to study the mechanical properties of low‐carbon steel under the coupling effect of the overall environment and the loads, the tensile mechanical test was carried out. The results indicated that, as the sea water concentration and tensile deterioration increased, both the mass‐loss rate and surface roughness of the low‐carbon steel gradually ...

Stress Corrosion Cracking Behavior of TP 439 and 690 TT under Film‐Forming Amine Environment

Scanning, Volume 2021, Issue 1, 2021., 2021
Film‐forming amines have been widely used in thermal power plants for maintenance after shutdown, and there are more and more applications and researches in nuclear power secondary circuits for this purpose. However, in the direction of stress corrosion cracking, there is not much research on the influence of film‐forming amines on metal materials ...

Corrosion Protection of Copper Foil by Ni-W Electrodeposited Coating in Kaolin Slurry

International Journal of Electrochemical Science, 2021
The electrodeposited Ni-W layer was coated on a Cu substrate, and the plating bath was treated with a nickel sulphate solution. The corrosion resistance of the coating layer was evaluated using a corrodkote test with 1-20 repetitive cycles, and the SSRT (
