  • A Model of Chromate Leaching from Inhibited Primers
    18th World IMACS / MODSIM Congress, Cairns, Australia 13-17 July 2009 http://mssanz.org.au/modsim09 A model of chromate leaching from inhibited primers Jenkins, D.R. 1 and A.D. Miller 2 1 CSIRO Mathematical and Information Sciences, Locked Bag 17, North Ryde NSW 1670 2 CSIRO Mathematical and Information Sciences, Private Bag No 2, Glen Osmond SA 5064 Email: [email protected] Abstract: We present a model of the production, transport and reaction of various ionic species involved in the process of leaching of chromate ions from primer layers on metal substrates. The polymer primer layers contain a range of filler particles, some of which are inert, while others are “active”, in the sense that they act to inhibit the onset and progression of corrosion in bare metal, in a situation where the primer layer is breached. A key active corrosion inhibitor is chromate ions, usually provided by strontium chromate (SrCrO4) particles in the primer. The chromate ions are formed by dissolution in water, which needs to penetrate the primer layer for this to occur. The ions then leach out to the damage site and react with the metal surface to inhibit corrosion. Unfortunately chromate is carcinogenic and therefore is now banned in various parts of the world. More acceptable alternatives for chromate are being keenly sought. A valuable aspect of chromate ions in their inhibitor role is their ability to relatively rapidly leach out after damage initiation, which is not true of many other inhibitors. However, aspects of the mechanism of chromate leaching through primer layers are not well understood.

  • DECOMPOSITION of MIXTURES of Strontlum CHROMATE and STRONTIUM CARBONATE
    PART V!. DECOMPOSITION OF MIXTURES OF STRONTlUM CHROMATE AND STRONTIUM CARBONATE. By V. T. Atlzaz~alealzd S. K. K. Jatkar. INTRBDUCTIQN. It has been shown in Part V (This Jo~trnal, 1938, ZlA, 159) that the decon~positionof strontium chromate indicated intermediate stages at 50, 66.6 and 75% clecomposition in conformity with our observations on the decomposition of calcium chromate (This Jownal, 1937, ZOA, 55-56). The stages corresponding- to 80 and 100% deconlposition could not be obtained in this case because of the lack of a suitable tube material which woulcl stand temperatures above 1450" in vacuum. While studying the decomposition of the mixtures of lime with calcium chromate (This Joz~mal, 21A, 119) two additional stages in the decomposition corresponding to 33.3 and 40% clecom- position were obtained, the composition of each stage being, respec- tively, identical with the acid-soluble portions from 66.6 and 75 % stages for plain chromate. The composition of the acid-soluble por- tion is thus an indication of the con~position of the intermediate stages obtained in the decomposition of the chromate when mixed with the corresponcling oxide. The difference in the behaviour of the con~poundsformed at the 50% stages for calcium and strontium chronlates towards acid has already been pointed out in Part V of this series. We thus get from 50% stage For strontium chromate, an acid-soluble compound 8Sr0 4Cr03 Cr,O, corresi~onclingto 33.3% decomposition, which though obtained otherwise in the decomposition of calcium chromate and its mixtures with lime, contained one mot of SrO less, ihile the corres- ponding stage in the decomposition of calcium chromate yields an acirl-soluble portion 10Ca0 6Cr0, Cr,O, A strontium compound corresponding to 33.370 stage was also obtained by treating the 66.6% stage with acid, the composition of which was 9Sr0 4Cr0, Cr,O,.

  • Barium, Zinc and Strontium Yellows in Late 19Th–Early 20Th Century Oil Paintings Vanessa Otero1* , Marta F
    Otero et al. Herit Sci (2017) 5:46 DOI 10.1186/s40494-017-0160-3 RESEARCH ARTICLE Open Access Barium, zinc and strontium yellows in late 19th–early 20th century oil paintings Vanessa Otero1* , Marta F. Campos1, Joana V. Pinto2, Márcia Vilarigues1, Leslie Carlyle1 and Maria João Melo1 Abstract This work focuses on the study of the 19th century yellow chromate pigments based on barium (BaCrO­ 4), zinc ­(4ZnCrO4 K2O 3H2O) and strontium ­(SrCrO4). These pigments, which are reported to shift in hue and darken, have been found· in· 19th century artworks. A better understanding of their historic manufacture will contribute to the visual/chemical interpretation of change in these colours. Research was carried out on the Winsor & Newton (W&N) 19th century archive database providing a unique insight into their manufacturing processes. One hundred and three production records were found, 69% for barium, 25% for zinc and 6% for strontium chromates, mainly under the names Lemon, Citron and Strontian Yellow, respectively. Analysis of the records shows that each pigment is charac- terised by only one synthetic pathway. The low number of records found for the production of strontium chromate suggests W&N was not selling this pigment formulation on a large scale. Furthermore, contrary to what the authors have discovered for W&N chrome yellow pigments, extenders were not added to these pigment formulations, most probably due to their lower tinting strength (TS). The latter was calculated in comparison to pure chrome yellow ­(PbCrO4, 100% TS) resulting in 92% for barium, 65% for zinc potassium and 78% for strontium chromate pigments.

    Cadmium and Hexavalent Chromium Alternatives 5-Year Strategy and Roadmap, Contract # W9128F-12-D-0041 25 May 2016 3150 Fairview Park Drive South Falls Church, Virginia 22042-4519 Cadmium and Hexavalent Chromium Alternatives 5-Year Strategy and Roadmap, Contract #W9128F-12-D-0041 Executive Summary The Strategic Environmental Research and Development Program (SERDP) and Environmental Security Technology Certification Program (ESTCP) Weapons Systems and Platforms Program Area has developed a strategy to reduce use of cadmium (Cd) and hexavalent chromium (Cr6+) by 90% or more at Department of Defense (DoD) maintenance depots over the next five years. The strategy includes objectives, metrics, and actions to demonstrate how this reduction can be achieved. The strategy employs site demonstrations and leverages DoD resources to replicate processes across the DoD depot community. It also includes a recommended future path for success in the advanced coatings area. As part of this effort, installation-specific implementation plans were developed in coordination with Letterkenny Army Depot (LEAD), Fleet Readiness Center Southeast (FRCSE), and Oklahoma City Air Logistics Complex (OC-ALC). These efforts helped inform the strategy. These implementation plans track to the overall Advanced Coating 5-Year Strategy and Roadmap, consist with DoD’s strategic vision as it pertains to Cr6+ and Cd reduction. DoD processes that contribute to current cadmium and hexavalent chromium use and production, and potential alternatives are illustrated in Figure ES-1.
