    In the trend change of two-year metallic corrosion, for all four metals, a higher corrosion rate can be seen in the initial stage; for aluminum and zinc, a stable corrosion rate can be seen in the second month. For carbon steel and copper, a stable corrosion rate can be seen in the sixth month.

  2. Monitoring pH in corrosion engineering by means of thermally produced iridium oxide electrodes

    Iridium oxide electrodes were thermally produced for long-term pH monitoring. The results show that the electrodes provide an accurate and reliable response to pH changes after more than 1 year of immersion in highly alkaline media.

  3. Protective property of epoxy coatings containing polyaniline and laminar basalt in neutral, alkaline, and acidic media

    Protective coatings incorporated with platelike inorganic fillers usually exhibit substantial enhancement in physical and chemical properties, including thermal stability, flame retardance, barrier resistance and stress corrosion prevention. The pathway of oxygen and other corrosion media through the coating matrix are prolonged intensively when the LBs are nearly parallel arranged in coating surface.

  4. In vitro corrosion behavior, bioactivity, and antibacterial performance of the silver-doped zinc oxide coating on magnesium alloy

    Nanostructured silver-doped zinc oxide (Ag-ZnO) coating was prepared on Mg-2Ca-0.5Mn-6Zn alloy surface with improved corrosion resistance and antibacterial activity through PVD. Nanostructured Ag-ZnO coated specimens presented lower Icorr, and higher Rct compared with uncoated Mg alloy. Antimicrobial examination has shown that Ag-ZnO coated specimen revealed a significantly better antimicrobial performance.

  5. A finite element model of carbon steel welded joint corrosion under plastic strain

    Y. X. Lu, H. Y. Jing, Y. D. Han and L. Y. Xu

    Version of Record online: 4 SEP 2017 | DOI: 10.1002/maco.201709620

    FE model is presented to simulate the mechano-chemical corrosion behaviour of welded joint. A decrease of weld reinforcement enhances the corrosion of weld metal under plastic strain. An increase of plastic strain aggravates the corrosion of welded joint. Weld metal properties can affect the mechano-chemical corrosion behaviour of welded joint.
