Ziel der durchgeführten Arbeiten war, verschiedene Oxide mit elektrochemischen Methoden in eine Zinkschicht einzubauen. Um den Mechanismus der Dispersionsabscheidung aufzuklären wurden die Feststoffpartikeln durch Zetapotentialmessungen, Partikelgrößenanalyse und die Bestimmung der spezifischen Oberfläche charakterisiert. Außerdem wurde die Abhängigkeit der Partikel-Einbaurate in den abgeschiedenen Zinkschichten von der Art des Bades, der Partikelkonzentration im Bad, der Rührgeschwindigkeit, dem pH-Wert, der Mahlung der Partikeln, der Art des elektrischen Stromes und der Elektrodenanordnung u

Thesis is focused on verification of suitability of Laser-TIG technology for penetrating welding of galvanized sheets, made of WSS M1A 365-A14 50G steel and DC01 steel. Electric arc functions here as a preheating for evaporation of zink layer. Electric current was chosen as a variable parameter of magnitudes 0, 20, 30 and 40 A. Test welds were made, which have been subjected to a tensile test and metallographic evaluation. The positive influence for electrolytically galvanized steel WSS M1A 365-A14 50G was registered and determination of optimal welding parameters was successful. The electric

Functional coatings produced using scalable and cost-effective processes such as electrodeposition and etching lead to the creation of random roughness at multiple length scales on the surface. The first part of thesis work aims at developing a fundamental mathematical understanding of multiscale coatings by presenting a fractal model to describe wettability on such surfaces. These surfaces are described with a fractal asperity model based on the Weierstrass-Mandelbrot function. Using this description, a model is presented to evaluate the apparent contact angle in different wetting regimes. Ex

In recent years, the suspected carcinogenic and toxic effects of hexavalent chromium have caused great concern, resulting in the imposition of stringent environmental and workplace regulations in the metal finishing industry.

With the increase use of de-icing salts on roads for safety, the need for improved corrosion resistance of the traditional galvanized automobile bodies has never been greater. In the present work, Zn alloy coatings (Zn-Ni and Zn-Co) were studied as an alternative to pure Zn coatings. The production of these deposits involved formulation of various acidic (pH of about 5.5) chloride based solutions. These showed anomalous deposition, that is, alloys were deposited much more easily than expected from the noble behaviour of Ni and Co metals. Coating compositions ranging from 0 to about 37% Ni and

Annotation:

Zinc and its alloys are among the most widely utilised metallic coatings for the sacrificial protection of steel. Although excellent in this mode of protection, these coatings are often less durable when subjected to environments of combined wear and corrosion due to their intrinsic relative softness and ductility. A possible and fast growing way of improving the durability of these coating is by the codeposition of inert particles into the zinc and zinc-alloy matrix. The main aim of this research was therefore to improve the durability of zinc and zinc-nickel coatings by the incorporation of

Zn-Mo coatings are very promising environment friendly anticorrosive coatings as replacement materials for cadmium and chromium (VI) based conversion layers. Electrodeposition has become a favorable technique in fabricating coatings due to its low cost, ease of use, and overall experimental control of coating quality. Very little research so far has been done for the electrodeposition of Zn-Mo coatings under alkaline conditions.

Corrosion of steel reinforcement in concrete bridges and parking garages due to the intrusion of chloride ions from deicing salt is a serious problem in northern climates. A number of approaches have been used in the past to mitigate steel corrosion. Cathodic protection is considered to be the only technique to slow down corrosion in salt contaminated concrete to a negligible rate. This is accomplished by either an impressed current anode or a sacrificial anode in the system. The impressed current anode system, with metallized zinc as the anode material, has been used with success on a number

Any replacement coating system should have all of the relevant properties that make cadmium so attractive, but without its obvious shortcomings.

L'objectif principal de ce travail est de comprendre les phénomènes de dissolution sélective et de cartographier la dissolution sélective des alliages Zn-Al et des alliages Zn-Mg-Al dans une moindre mesure en fonction du pH et de potentiel. Cela aidera à construire un modèle prédictif de couplage galvanique qui est une préoccupation majeure de l'industrie automobile. Pour s'approcher de la cible, nous utilisons la spectroélectrochimie d'émission atomique (AESEC) qui est une combinaison de méthodes électrochimiques et analytiques. Cette technique nous permet de quantifier en temps réel et sépar

Objectives: Orthopaedic and dental implants are prone to frequent infections. This can lead to detrimental and often irreversible outcomes for many patients. The objective of this study was to develop a novel system using zinc oxide nanoparticles (nZnO) as a coating material that inhibits both bacterial adhesion / growth and promotes osteoblast growth. Methods and Results: Initially bacteria (S. aureus, E. coli, S. epidermidis and P. aeruginosa) were exposed to different concentrations of zinc oxide nanoparticulate suspensions (250 μg/mL, 500 μg/mL, 1000 μg/mL and 2500 μg/mL); with the higher

O zinco vem sendo utilizado, já há bastante tempo, como revestimento protetor e decorativo para peças metálicas [1]. No entanto, cada vez mais a indústria busca revestimentos protetores que sejam mais resistentes à corrosão, que tenham boas características de soldabilidade, pintabilidade e, principalmente baixo custo. Os métodos mais comuns pelos quais os revestimentos de zinco são aplicados são imersão a quente, eletrodeposição e aspersão térmica. O presente trabalho tem como objetivo caracterizar a morfologia dos revestimentos Galvanized (GI), Galvannealed (GA) e Zn-55Al de zinco obtidos pel

Electroplated zinc-alloy coatings have been used on fasteners in the automotive industry for many years. The coating often consists of three layers: a zinc-alloy layer, a passivation layer and a sealer or top-coat. The coating layers affect the functional properties of the fastener (mainly the corrosion resistance, friction coefficient and electrical conductivity), and the aim of this thesis has been to increase the understanding of how these functional properties are affected by the properties of the coating. The corrosion resistance, friction coefficient and electrical conductivity of severa
