Atomic level bonding mechanism in steel/aluminum joints produced by cold pressure welding
Peter, Nicolas J.; Gerlitzky, Christiane; Altin, Abdulrahman; Wohletz, Simon; Krieger, Waldemar; Tran, The Hai; Liebscher, Christian H.; Scheu, Christina; Dehm, Gerhard; Groche, Peter; Erbe, Andreas (Journal article, 2019)Cold pressure welding of aluminum alloys and steels offers an attractive, cost-effective opportunity of joining the two most important structural materials. Aim of this work is to investigate the bonding mechanism between ... -
Cathodic delamination kinetics of thin polystyrene model coatings bound to zinc via organosilanes
Iqbal, Danish; Rechmann, Julian; Bashir, Ali; Sarfraz, Adnan; Altin, Abdulrahman; Erbe, Andreas (Journal article; Peer reviewed, 2018)The cathodic delamination of poly(styrene) [PS] model coatings from oxidecovered zinc has been evaluated by scanning Kelvin probe (SKP). Linear and acrylate cross-linked PS model coatings covalently bound to zinc oxide ... -
Comparison of cathodic delamination of poly(n-alkyl methacrylates) on iron
Mondragon Ochoa, Jesus S.; Altin, Abdulrahman; Erbe, Andreas (Journal article; Peer reviewed, 2017)Cathodic delamination is measured on iron surfaces covered with different poly(n-alky methacrylates), where the alkyl is an n-CnH2n + 1 (n = 1, 4, 18) group. The polymers are prepared by free radical polymerization in ... -
Cyclodextrin inhibits zinc corrosion by destabilizing point defect formation in the oxide layer
Altin, Abdulrahman; Krzywiecki, Maciej; Sarfraz, Adnan; Toparli, Cigdem; Laska, Claudius; Kerger, Philipp; Zeradjanin, Aleksandar; Mayrhofer, Karl J.J.; Rohwerder, Michael; Erbe, Andreas (Journal article; Peer reviewed, 2018)Corrosion inhibitors are added in low concentrations to corrosive solutions for reducing the corrosion rate of a metallic material. Their mechanism of action is typically the blocking of free metal surface by adsorption, ... -
Cyclodextrins as carriers for organic corrosion inhibitors in organic coatings
Altin, Abdulrahman; Rohwerder, Michael; Erbe, Andreas (Journal article; Peer reviewed, 2017) -
Delamination kinetics of thin film poly(acrylate) model coatings prepared by surface initiated atom transfer radical polymerization on iron
Mondragon Ochoa, Jesus S.; Altin, Abdulrahman; Rechmann, Julian; Erbe, Andreas (Journal article; Peer reviewed, 2018)Living radical polymerization is often considered as an unsuitable method of surface modification for reactive metals such as iron. Necessary noble metal catalyst systems may react with the surface to be modified, causing ... -
Mechanisms of inhibitor action - passivation and self-healing
Jevremovic, Ivana; Chen, Ying-Hsuan; Altin, Abdulrahman; Erbe, Andreas (Chapter, 2020)In this chapter, we will briefly review the systematics of corrosion inhibitors and the classical mechanisms of action of corrosion inhibitors, the latter with an emphasis on inhibitors interacting with the material surface. ... -
Pretreatment with a β-cyclodextrin - corrosion inhibitor complex stops an initiated corrosion process on zinc
Altin, Abdulrahman; Vimalanandan, Ashokandand; Sarfraz, Adnan; Rohwerder, Michael; Erbe, Andreas (Journal article; Peer reviewed, 2018)Metal pretreatment is typically the first step in a reliable corrosion protection system. This work explores the incorporation of complexes between the cyclic oligosaccharide β-cyclodextrin (β-CD) and the molecular organic ... -
State of the surface of antibacterial copper in phosphate buffered saline.
Toparli, Cigdem; Hieke, Stefan; Altin, Abdulrahman; Kasian, Olga; Scheu, Christina; Erbe, Andreas (Journal article; Peer reviewed, 2017)The state was investigated of the copper surface in phosphate buffered saline (PBS; 140 mM Cl−, 10 mM phosphate; pH 7) by a combination of cyclic voltammetry (CV) and chronoamperometry (CA) with in situ spectroscopic ...
