  1. 1. Corrosion initiation induced by sodium sulfate and sodium chloride particles on Cu and the golden alloy Cu5Al5Zn at simulated atmospheric conditions

    University essay from KTH/Materialvetenskap

    Author : Weijie Zhao; [2017]
    Keywords : atmospheric corrosion; sodium sulfate; sodium chloride; Cu5Al5Zn; Cu metal; mixed salt pre-deposition; laboratory exposure; LOM; SEM EDS; ATR-FTIR; cathodic reduction;

    Abstract : Effects of sodium sulfate (Na2SO4) particle deposition on the atmospheric corrosion of copper (Cu) metal and a Cu-based alloy (Cu5Al5Zn) used in architectural applications were investigated at laboratory conditions compared with effects induced by sodium chloride (NaCl) and to some extent ammonium sulfate (NH4)2SO4 induced corrosion. Pre-deposited surfaces were exposed to repeated wet/dry conditions in a climatic chamber and the formation of corrosion products were assessed using light optical microscopy (LOM), scanning electron microscopy with elemental analysis (SEM/EDS), Fourier transform infrared techniques (FTIR microscopy) and cathodic reduction (CR).

  2. 2. Radiation induced corrosion of copper

    University essay from KTH/Skolan för kemivetenskap (CHE)

    Keywords : Copper; radiation; gamma radiation; corrosion; SEM; IRAS; ICP; cuprite;

    Abstract : The Swedish concept for storage of highly radioactive spent nuclear fuel is called the KBS-3 program. The proposed procedure is that the waste will be stored in a deep repository, 500 meters down in the Swedish bedrock, for 100 000 years. The fuel will be sealed inside cast iron cylinders surrounded by copper. READ MORE
