The Mechanism of Phase Transformation to Obtain Zinc-Iron Coatings
(Universitatea "Dunărea de Jos" din Galați, 2009)
Important changes in the ratio of constitutive phases take place during heating
of galvanized parts due to Zn coating layer changed into Zn-Fe alloy. The work
deals with a mathematical correlation between diffusion ...
Obtaining and Characterisation of Thermoresistive Pigments
(Universitatea "Dunărea de Jos" din Galați, 2009)
The paper describes the obtaining and chemical and physico-structural
characterisation of a green thermoresistive pigment. The pigment is made of ZnO
