Cavitation Erosion Comparison Between Commercial Coatings and Polyurethane Coating Containting Nano-Carbon

Product Number: 41214-830-SG

Author: Se-Woong Kim, Chae-Seon Lim, Sang-Ki Chi, Jun-Young Choi, Jae-Hak Kim

Publication Date: 2014

Cavitation erosion occurring on the rudder, which is induced by cavities from a rotating propeller due to the local pressure decrease of the fluid, has adverse effect on the operation of the vessel. Cavitation resistant paints have been highly considered to prevent the rudder from eroding, because of its relatively easy application and low working cost compared to other preventing methods.

Characterization Of The Surface Chemistry At Corroded And Non-Corroded Sites On Aluminum Alloy 7075-T6 Samples Exposed At Coastal Locations

Product Number: 51322-17642-SG

Author: Douglas C. Hansen, David Borth, Farrah Cole

Publication Date: 2022

$20.00

Knowledge of the localized corrosion environment on a metal substrate can provide the critical link between atmospheric data and corrosion morphology and can enable the formation of a framework to predict service life as a function of environment. Over the last few decades the analytical characterization of bare metal surfaces undergoing atmospheric corrosion has improved, resulting in a more complete understanding and consideration of the environmental parameters involved. However, the corrosion processes and the role that the environmental parameters play in what is a multiphase system is rather complex involving chemical reactions and equilibria, ionic transport phenomena, and gaseous, aqueous and solid phases.

Detection of Surface Contamination During a Scheduled Inspection and Repair Investigation

Product Number: 41209-488-SG

Author: Lyn Kearns, Martin Janssen, Jean-Luc Coté

Publication Date: 2009

$20.00

The Department of National Defence (DND) in Canada has implemented a revised maintenance program for aircraft weapon systems whose goal is to ensure that essential maintenance is accomplished and to assure the continued airworthiness of aeronautical products during in-service operation. The program especially affects legacy aircraft. A case study is being presented where an adhesion failure was detected during a scheduled inspection.

Nuclear energy currently contributes approximately 10 % of the worldwide energy mix.¹ Nuclear energy generation is a form of low-carbon electricity, typically run as base-load, which alongside renewables can help nations toward climate change goals. Nuclear fission thermal reactors make up the majority of the reactors operating today. Nuclear fusion on the other hand is a promising alternative which produces less radioactive waste and does not have a reliance on the finite source of uranium fuel. Eurofer-97, a reduced activation ferritic-martensitic (RAFM) steel, will be used as a structural material for fusion reactors. The earliest literature reference to RAFM steels originated from 1994 by Abe et al.² One option for the European demonstration fusion reactor (DEMO) is to use a water-cooled lead-lithium (PbLi) breeder blanket (WCLL BB) design for heat extraction. Breeder blankets will be used to generate a source of tritium, for the fusion reaction with deuterium.

Initiation Sites of Pitting Corrosion in the Nickel Alloy UNS N07718

Product Number: 51323-18846-SG

Author: Julia Botinha, Bodo Gehrmann, Helena Alves, Michael Rohwerder

Publication Date: 2023

$20.00

Being one of the most applied nickel alloy in the oil and gas industry, the UNS N07718 (Alloy 718) is mainly composed by nickel, chromium, iron, molybdenum, niobium, titanium and aluminum. UNS N07718 is used in the solution annealed and precipitation hardened condition, where a complex microstructure is formed, which is responsible for its very good mechanical properties, as well as its cracking and corrosion resistance.

ON THE TOPOGRAPHICAL AND PERFORMANCE EFFECTS OF REBLASTING A PREVIOUSLY PREPARED STEEL SUBSTRATE

Product Number: 51218-141-SG

Author: Carl Reed, Kat Coronado

Publication Date: 2018

$20.00

Of recent interest in the coatings world, is what to do when an abrasive blasted substrate does not meet the specified profile. For example, if the blast profile on a steel surface exceeds the specification limit, can the surface be reblasted with smaller abrasive blast media to reduce the profile into meeting the specification? At SSPC 2017 a paper was presented which addressed this scenario and found that the profile can be reduced using such reblasting process.

On the Topographical and Performance Effects of Underblasted and Reblasted Carbon Steel Substrate

Product Number: 51220-278-SG

Author: Carl Reed, Kat Coronado, Heather Cui

Publication Date: 2020

$20.00

In this study, the effect on coating corrosion resistance after remediating an under-blasted then remediated to standard preparation is undertaken. In this work, it is proposed to under-blast one set of panels (~1 mil profile), blast to standard one set of panels (~3 mil profile) and remediate to standard a set of under-blasted panels (from ~1 mil profile to ~ 3 mil profile).
