Effect of surface abrasion on pitting corrosion of Al-Li alloy
10.1016/j.corsci.2018.04.010 2018-04-09 The effects of surface abrasion on microstructure and pitting corrosion of 2297 A l-Li alloy were investigated. Statistical analysis reveals that surface abrasion alters surface roughness and induces partial dissolution of intermetallic particles. A smoother ... |

The Corrosion behavior of Ni-Cu gradient layer on the nickel aluminum-bronze (NAB) alloy
10.1016/j.corsci.2018.03.050 2018-04-07 The gradient Ni-Cu layer on nickel aluminum-bronze alloy was obtained by the thermal diffusion process. The corrosion resistance was improved due to the formation of protective film, consisted of Ni(OH)2 and Cu2O. Although the Ni-Cu layer exhibited local corr... |

Dealloying induced N-doping in spindle-like porous rutile TiO2 for enhanced visible light photocatalytic activity
10.1016/j.corsci.2018.03.049 2018-04-03 We designed a high-yield and low temperature N-doping strategy in modifying TiO2 band structure. A nanostructured porous TiO2 was obtained through dealloying of Cu80Ti20 precursor through leaching by HNO3. It was confirmed that nitrogen was interstitially dop... |

Bi-modal trending for corrosion loss of steels buried in soils
10.1016/j.corsci.2018.03.048 2018-03-29 Corrosion loss data from the 1957 NBS study for steels buried in a large variety of soils and exposed over 12-17 year s are re-interpreted, supported with estimates for scatter in the data. This shows that losses predominantly are consistent with the bi-modal... |
