Morphological Aspects and Corrosion Behaviour of Phenol Formaldehyde/Zn Composite Coatings
(Universitatea "Dunărea de Jos" din Galați, 2009)
The present work has the purpose of studying morphological aspects and
corrosion behaviour of pure zinc and composite coatings having zinc as metal
matrix and phenol – formaldehyde resin type Novolac (RESITAL 6358/1) ...
Study of Zro2/Co-Deposition with Cobalt from Chloride Electrolyte
(Universitatea "Dunărea de Jos" din Galați, 2009)
The metal-matrix composites are materials in which the properties of a
metallic host material are modified with addition of a second phase (ceramics) by
electrodeposition process. The second phase can be hard oxides or ...
Researches on the Corrosion Behavior for a Drawing Steel That Went Through Natural Ageing
(Universitatea "Dunărea de Jos" din Galați, 2009)
The paper presents the results of a study on the corrosion behaviour of the
sheets of drawing steel with 0,04% C gone through natural ageing and run for a
period of 112 days from the moment of drawing. The researches ...
