    Materials Selection & Design: Corrosion Analysis of a Newly Installed Family Heating System


    Author(s): Zhanjun Guo, North China University of Water Resources and Electric Power; Zhiliang Chen, Chinese Academy of Sciences

    A corrosion analysis of a newly installed domestic (residential) heating system was carried out after it suffered corrosion attack in less than three months of operation. The makeup water had a high salt concentration and a low pH value. In addition, the make-up...

    Coatings & Linings: Case History-High-Temperature Material Selection for a Powder Processing Environment


    Author(s): Roger Barnett, TWI

    A high-temperature powder processing cell experienced significant corrosion at 1,100 °C within 30 days. To select appropriate materials for service, trials were carried out on engineering alloys at 1,100 °C for 336 h. Two simulated environments were used; 10%...

    Feature Article: Testing Materials for Corrosion in an Icelandic Geothermal Environment


    Author(s): Kathy Riggs Larsen, Editor

    Geothermal power stations, which use heat energy from the Earth's core, are similar to other power stations that use heat from a fuel source to create steam that turns turbines to generate electricity. Because these power plants use steam from a renewable energy...

    Attenuation of Forced Drainage Effects on Long Uniform Structures

    Published: February 01, 2018
    Author(s): Robert Pope, Bell Telephone Laboratories

    When forced drainage is applied to an underground metallic structure to provide cathodic protection, the greatest effects on the structure and earth potentials occur in the vicinity of the drainage point and anode. These effects taper off as the distance from...

    Materials Selection & Design: Effects of Anions on Crevice Corrosion of Copper

    Published: November 01, 2017
    Author(s): Qiufa Xu, China Academy of Launch Vehicle Technology; Kewei Gao and Xiaolu Pang, University of Science and Technology Beijing

    The effects of chloride (Cl-), sulfate (SO4 2-), and carbonate (CO3 2-) ions on the crevice corrosion behavior of copper were examined. The results indicated that chloride and sulfate ions increase crevice corrosion of copper, while the presence of carbonate...

    Coatings & Linings: Hydrogen Sulfide Tube Failure in a Seawater Heat Exchanger

    Published: September 01, 2017
    Author(s): Hanan Farhat, College of the North Atlantic-Qatar; Roy Johnsen, Norwegian University of Science and Technology

    Severe tube damage was discovered in a heat exchanger in which tubes made from 90/10 CuNi (UNS C70600) had thinned and collapsed. The main cause of the failure was severe tube thinning due to hydrogen sulfide (H2S) corrosion. Sulfur was introduced into the shell...

    Materials Selection & Design: Rust Layer Characterization of a Buried Drinking Water Pipe

    Published: September 01, 2017
    Author(s): Zhanjun Guo, North China University of Water Resources and Electric Power; Zhiliang Chen, Chinese Academy of Sciences

    The surface corrosion layer of a steel water pipe buried ~30 years in a soil environment was investigated by conventional and synchrotron x-ray diffraction (XRD). The results indicate the surface rust layer had entered a stable state with a higher amount of...
