Elastic Modulus of Coatings by Pendulum Impact Test
(Universitatea "Dunărea de Jos" din Galați, 2014)The pendulum impact scratch device with high precision system in measuring normal and tangential forces during scratching has been used to study elastic modulus of coatings. The criterion for evaluation of elastic modulus ... -
Examining the Evolution of Microstructure and ITS Effect on the Mechanical and Tribological Properties
(Universitatea "Dunărea de Jos" din Galați, 2017)This paper investigates the superior frictional performance of Ti-DLC films, by examining the evolution of microstructure and its effect on the mechanical and tribological properties. The superior frictional performance ... -
Physico-Mechanical Characteristics of Hard Alloys Made Out of Many Carbides
(Universitatea "Dunărea de Jos" din Galați, 2005)The Hard alloys of type WC-TiC-Co can be used to process materials with long chips, such as steels [1]. Titanium carbide or TiC-WC solid solutions, added as alloying constituents in the compositions of WC-Co pseudo-alloys ... -
Residual Stress and Tribology Behaviour of TiCx Coating Deposited by NPCVD Method
(Universitatea "Dunărea de Jos" din Galați, 2014)In this paper, thin TiCx films were coated by chemical vapour deposition method, and various duty cycles were carried out in order to observe the influence of this parameter on residual stress and tribology behaviours. ... -
Study of the RV52 Steel Plates Properties After Thermic Treatment
(Universitatea "Dunărea de Jos" din Galați, 2009)The thermal treatment of RV52 steel plates determines high mechanical properties such as: strength, wear resistance and tenacity. The normalized plate samples were studied to determine the effect of the tension release ... -
The Different Practical Application of Niobium Carbide Coatings Elaborated by CVD Process
(Universitatea "Dunărea de Jos" din Galați, 2016)In this paper, the different application of niobium carbide coatings onto hard carbide substrate was investigated using scanning electron microscope (SEM), Xray diffractometer (XRD) and micro-hardness. The paper conducted ... -
The influence of the physical-Chemical Factors on the Distribution of Heavy Metals in the Delta Ecosystems
(Universitatea "Dunărea de Jos" din Galați, 2015)Recognized to the influence of micropollutants, heavy metals represented on the ecological status of surface waters, including delta ecosystems, the paper aims to study the impact of environmental factors (temperature, ... -
The Protective Behaviour Titanium Nitride Coatings
(Universitatea "Dunărea de Jos" din Galați, 2015)The experiments conducted to obtain a thin layer of nitride through the vapour chemical deposition method have followed an original path to obtain TiN directly in the working room thus avoiding the import of these ...
