Materials and Corrosion:Early View

Jun 29, 2020 · The bark resin of Schinus molle (BRSM) exhibits moderate corrosion inhibition for API5L X70 steel in 0.5M sulfuric acid. The addition of iodide ions enhances the inhibition efficiency of BRSM significantly, from 63 to 99%. The BRSM/KI system inhibits significantly both the anodic and cathodic processes. Abstract.

Jan 01, 1996 · Thus, tantalum is widely used for heat transfer devices working in concentrated acidic media (e.g. plate and tube heat exchangers, bayonet heaters and thermowells, etc.). Its good tensile strength is required for the manufacture of some devices (e.g. rupture disks, impellers).

Tritium recovery from liquid metals - ScienceDirect

Mar 02, 1995 · In Pb-17Li, 316L austenitic steel forms a porous ferritic corrosion layer at its surface due to the preferen- tial dissolution of nickel. In contrast, the ferritic or martensitic steels undergo homogeneous dissolution [3,9,41,43]. Unlike liquid Li, non-metallic impurities (e.g. carbon and nitrogen) have no effect on the corro- sion by Pb-17Li [10]. US6387540B1 - Sacrificial corrosion-protective aluminum There is disclosed a sacrificial corrosion-protective aluminum alloy for heat exchangers which contains Zn more than 4.0 wt % but 15.0 wt % or less, 0.1 to 3.0 wt % of Fe, and 0.2 to 3.0 wt % of Ni, with the balance being made of aluminum and unavoidable impurities. There is also disclosed an aluminum alloy composite material in which the said aluminum alloy is used as the sacrificial material
