Solvent-based acrylic carbon paint anodes were installed on the north approach spans of the Yaquina Bay Bridge (Newport OR) in 1985 and performed well after 15 years. Anodes were inexpensive and repairs easy. Depolarization potentials are consistently above 100 with long-term current densities around 2 mA/m 2. Bond strength remains adequate.

51317--9779-Pitting Corrosion in AZ31 Magnesium Alloy in Potassium-Based Electrolytes

Product Number: 51317--9779-SG

ISBN: 9779 2017 CP

Author: Somi Doja

Publication Date: 2017

$20.00

AZ31 (UNS M11311) is a wrought magnesium alloy used in aerospace and automotive applications. In this work, KOH-based electrolytes were used to study the corrosion behavior of AZ31 alloy in highly alkaline environment. The effect of dopants and exposure time on pit initiation was studied via optical and scanning electron microscopy.

51318-11039-Reinforcing the Anticorrosion Property of Epoxy Coating Utilizing Urea–formaldehyde Resin

Product Number: 51318-11039-SG

Author: Hongpeng Zheng / Yawei Shao

Publication Date: 2018

$20.00

Urea–formaldehyde resin was applied to an epoxy coating. The UF resin effectively prevented the corrosive medium from further permeating through to the interface between coating and steel substrate and that the UF resin could significantly reinforce the corrosion protection property.

Comprehensive Laboratory Analysis Of AC Coupon Test Stations

Product Number: 51322-18151-SG

Author: Mehrooz Zamanzadeh, Martin Latona, George Bayer, Anil Kumar Chikkam

Publication Date: 2022

$20.00

Several alternating current (AC) coupon test stations (CTS) located near AC power lines were investigated to assess the AC interference corrosion risk of the test coupons. Asstation consisted of two ½ inch (1.27 cm) diameter and 1received each AC test inch (2.54 cm) long carbon steel (CS ) coupons. Coupons are much larger than 1 cm ² and current density measurements are not 100% relatable to the SP21424 or ISO 18086 criteria, since these refer to measurements on (typically) 1 cm² . The current densities measured on the coupons in this study will underestimate the AC corrosion threat.

Effect of Cementite on the Corrosion Inhibition of Carbon Steel with Tetradecyl Phosphate Ester in CO2 environment

Product Number: 51323-19309-SG

Author: Shuai Ren, Xi Wang, David Young, Marc Singer, Maalek Mohamed-Said, Gregory Moulie, Mioara Stroe

Publication Date: 2023

$20.00

Internal corrosion of pipelines associated with oil and gas production and refinery has always been a challenge for corrosion engineers. Over the past decades, corrosion engineers have made significant progress in developing mitigation approaches to protect these carbon steel pipelines by using corrosion inhibitors (CIs), corrosion resistant materials, and various cleaning techniques. Among all these mitigation strategies, corrosion inhibitors are considered as the first choice in handling the internal corrosion of pipelines.

Is 22 HRC the right threshold for TMCP large diameter pipes in severe sour environment?

Product Number: 51323-18943-SG

Author: Hervé Marchebois, Christophe Mendibide, Bruce Cowe, Carole Dessolin

Publication Date: 2023

$20.00

The manufacturing and field experience of high strength low alloy (HSLA) steel plates produced by Thermo-Mechanical Controlled Process (TMCP) are well defined in industry standards and literature. The TMCP method consists of a well-prescribed rolling pass schedule followed by accelerated cooling that leads to a fine-grain microstructure with the desired mechanical properties of the produced plates.
Quite recently, this TMCP process resulted in detrimental local variations with hidden hardness variations on pipe ID, so-called Local hard Zones (LHZ).
