Corrosion Control Without the Use of Toxic Heavy Metals

Product Number: 41213-793-SG

Author: Tony Gichuhi, David Tarjan

Publication Date: 2013

$20.00

Until recently heavy metal-based corrosion inhibitors were widely accepted as the best materials that could provide the corrosion protection needed in coatings. Corrosion inhibitors provide an indispensable function in protective coatings. The performance of a coating under corrosive conditions requires that corrosion inhibitors provide sustainable protection during the coating’s lifetime.

Development of Eco-friendly Chromium Electrodeposit for Corrosion Resistance in Chloride-containing Environment

Product Number: 51323-19027-SG

Author: Bright O. Okonkwo, Chaewon Jeong, Taejeong An, Hyun Joon Eom, Changheui Jang

Publication Date: 2023

$20.00

Overtime, chromium has traditionally been used as a surface coating in numerous industrial application such as automotive and general engineering products because of its excellent wear resistance, low coefficient of friction, high resistance to hear and corrosion. Owing to its advantages, several deposition methods have been developed to coat Cr on different surfaces such as plasma nitriding, vapor deposition, physical coating spray, electrodeposition and others. Among these techniques, electrodeposition stands out because of its simple and versatile approach to producing Cr deposit under ambient temperature and normal pressure, with benefits of low cost, high deposition rate, good homogeneity of coating thickness, and intriguing ability to coat substrates of complicated geometrical forms.

Effect Of Chromium Dilution On SCC Growth Rate In Inconel Welds

Product Number: ED22-17109-SG

Author: Ainsley Pinkowitz, David S. Morton, Tyler E. Moss, John V. Mullen

Publication Date: 2022

$20.00

Naval Nuclear Laboratory has developed Alloy 52i, a high chromium (~27 wt%) weld metal that can be welded onto Alloy 600, Alloy 625, or Alloy 690 wrought material. Alloy 52i by itself has shown to be very resistant to SCC in deaerated pure water. However, there is a concern when welding Alloy 52i onto the more SCC susceptible Alloy 82H or Alloy 600 that the first weld bead would be chromium diluted by the mixing with the lower-chromium base metal. This lower chromium level may lead to higher SCC susceptibility than the surrounding weld metal, since chromium content has shown a correlation with nickel alloy SCC susceptibility. In commercial nuclear power applications, many plant components are limited by SCC propagation in welded components within the weld metal; this test program seeks to understand which weld combinations, with respect to chromium concentration, may yield deleterious SCC properties for improved lifetime of plant components.

Metallurgical Aspects of HTHA in CS Below Traditional Nelson Curve Values

Product Number: 51320-15062-SG

Author: Jorge Hau

Publication Date: 2020

$20.00

High-Temperature Hydrogen Attack (HTHA) is a phenomenon that involves the formation and accumulation of methane (CH4) in steels operating under conditions where there is hydrogen ingress. To account for the phenomenon, it is necessary to know how the supply of solute carbon atoms occurs. What is discussed here concerns only low-carbon steel within the range 0.08-0.30 wt % carbon that has no intended additions of alloying element such as chromium (Cr) or molybdenum (Mo), and that it is typically delivered in the as-hot worked or normalized condition, resulting in microstructure consisting of pearlite colonies within a matrix of ferrite grains. Carbon steels do not normally contain carbon atoms in solid solution, but most are tied to cementite (Fe3C), except when retained in supersaturated solid solution by rapidly cooling from just below the subcritical temperature Ac1, 727 °C (1340 °F), in which case, the solute carbon atoms do not remain in supersaturated solution for long, they precipitate, but the resulting precipitates are rather unstable and get quickly thermally activated when heated to temperatures that are considered relatively too low to significantly affect the cementite in existing pearlite colonies. Thus, these precipitates may supply solute carbon atoms for HTHA damage to occur at temperatures that would not otherwise occur if there were only cementite in existing pearlite colonies.

SSPC-Guide 18-2022, Specifier’s Guide for Determining Containment Class and Environmental Monitoring Strategies for Lead Paint Removal Projects

Product Number: SSPC-GUIDE 18-2022

Publication Date: 2022

$109.00

This Guide describes a six-step process to assist in determining the type of containment system and the level of environmental monitoring that should be specified on a project-specific basis when removing coatings that contain lead. The selection of the containment and monitoring strategies is based on an assessment of the type of paint removal method that will be used and the potential impact of the operations on the public, other workers in the area, and the environment. Note that local and state codes and regulations must be reviewed and take precedence to any guidance provided in this document.

The guidance provided in this document also applies to coatings containing other hazardous metals such as cadmium and chromium; however, the recommended analytical monitoring is often based on an analysis for lead. Paint chip sampling and testing for lead and other hazardous metals should be undertaken to properly characterize the paint being removed.

This Guide does not cover the selection of paint removal methods, or design of containment/ventilation systems.
