Assessment of Coating Adhesion Degradation by Atomic Force Microscopy Scratching

host posted on March 01, 2012 00:00
J. Seong and G. S. Frankel
The effects of environmental exposure on polymer coating degradation were studied using atomic force microscopy (AFM) scratching. Adhesion was assessed by the coating removal rate during controlled-force contact mode scratching in the AFM. Low-carbon steel coupons were coated with an ultra-high mo ...

Effect of S-Phase Dissolution on the Corrosion and Stress Corrosion Cracking of an As-Rolled Al-Zn-Mg-Cu Alloy

host posted on March 01, 2012 00:00
D. K. Xu, N. Birbilis, and P. A. Rometsch
The effect of two specific solution heat treatment procedures on the corrosion and stress corrosion cracking (SCC) susceptibility of an as-rolled Al-Zn-Mg-Cu alloy was investigated. It is shown that for a stepped solution treatment with a final temperature of 495°C, the SCC resistance of subsequen ... [Corrosion 68, 035001 (2012)] published Thu Mar 01, 2012.

A. Rauf, W. F. Bogaerts, and E. Mahdi
The electrochemical frequency modulation (EFM) technique has been used to investigate its ability to monitor stress corrosion cracking (SCC) of sensitized stainless steel U-bend specimens in sodium thiosulfate (Na2S2O3) and sodium chloride (NaCl) solutions. Type 304 (UNS S30400) stainless steel wa ... [Corrosion 68, 035002 (2012)] published Thu Mar 01, 2012.

R. P. Case, H. E. Rincon, and D. R. McIntyre
This study examines the effect of hydrogen sulfide (H2S) on the transition from metastable to stable propagating pits using Type 316L (UNS S31603) steel in brines with Cl− concentrations of 10−3 M to 2×10−2 M at 75°C and 150°C. The potentiostatic tests were performed at discrete intervals of 50 mV ... [Corrosion 68, 035004 (2012)] published Thu Mar 01, 2012.

Metallurgical and Physical Factors Controlling the Multi-Functional Corrosion Properties of Pulsed Thermal-Sprayed Al-Co-Ce Coatings

host posted on March 01, 2012 00:00
N. R. Tailleart, B. Gauthier, and S. Eidelman et al.
A high-density, low-porosity Al-Co-Ce metallic coating has been applied successfully to an aluminum alloy (AA)2024-T351 (UNS A92024) substrate using a pulsed thermal spray (PTS) process in thicknesses ranging from 100 µm to 500 µm. The three proposed modes of corrosion protection brought about by ... [Corrosion 68, 035006 (2012)] published Thu Mar 01, 2012.

Effects of Oxygen and Sulfate Concentrations on the Corrosion Behavior of Zinc in NaCl Solutions

host posted on March 01, 2012 00:00
V. E. Padilla Perez and A. Alfantazi
Galvanized steel is one of the most common materials used in the construction industry for its relatively low cost paired with an acceptable corrosion resistance. Nevertheless, the early failure of a number of structures around the world that use galvanized steel as reinforcement has raised some c ... [Corrosion 68, 035005 (2012)] published Thu Mar 01, 2012.

Oxidation Behavior of Cu-38at%Zn Foils After Surface Mechanical Attrition Treatment

host posted on March 01, 2012 00:00
C. H. Xu, C. S. Wen, and S. Q. Shi et al.
A commercial Cu-38at%Zn foil was subjected to surface mechanical attrition treatment (SMAT) processing. The isothermal oxidation behavior of the SMAT Cu-38at%Zn over the temperature range of 773 ∼ 1,123 K was studied and compared with that of original Cu-38at%Zn. Characterization of the oxidized s ...

Modification of ASTM B117 Salt Spray Corrosion Test and Its Correlation to Field Measurements of Silver Corrosion

host posted on March 01, 2012 00:00
Y. Wan, E. N. Macha, and R. G. Kelly
Laboratory salt spray testing has been used for many years to accelerate natural atmospheric exposures with limited success. The corrosion of silver represents a stark example of the failings of such testing. In virtually any field environment, silver corrodes measurably in a month, but after 4 mo ...

Predicting the Long-Term Field Performance of Coating Systems on Steel Using a Rapid Electrochemical Test: The Damage Tolerance Test

host posted on March 01, 2012 00:00
S. R. Taylor, F. Contu, and L. M. Calle et al.
The pace of coatings development is limited by the time required to assess their corrosion protection properties. This study takes a step forward from past studies and correlates the corrosion performance of protective coatings assessed by a series of short-term electrochemical measurements with 1 ...
