Implementation of the Chicot-Lesage Composite Hardness Model in a Determination of Absolute Hardness of Copper Coatings Obtained by the Electrodeposition Processes
(Metals, 2021)
The influence of various electrolysis parameters, such as the type of cathode, composition of the electrolyte and electrolysis time, on the morphology, structure and hardness of copper coatings has been investigated. ...
Structure and Strength of Isothermally Heat-Treated Medium Carbon Ti-V Microalloyed Steel
(Metals, 2021)
Isothermal transformation characteristics of a medium carbon Ti-V microalloyed steel were investigated using light microscopy, scanning electron microscopy (SEM) equipped with energy dispersive spectroscopy (EDS), and by ...
Synthesis of Silica Particles Using Ultrasonic Spray Pyrolysis Method
(Metals, 2021)
Silica has sparked strong interest in hydrometallurgy, catalysis, the cement industry, and paper coating. The synthesis of silica particles was performed at 900 degrees C using the ultrasonic spray pyrolysis (USP) method. ...
Utilization of agro-industrial waste for removal of copper ions from aqueous solutions and mining-wastewater
(Elsevier Science Inc, New York, 2019)
In this study, unmodified lemon peel, as agro-industrial waste, was used to investigate removal efficiency of copper ions from aqueous solutions and mining wastewater. The effects of solution pH, adsorption time, metal ion ...
Advanced damage resistance monitoring procedure on the composite materials? surface-exposed to cavitation testing
(Wear, 2021)
Morphology and development of surface damage of alumina-based materials, resulting from cavitation erosion is studied in this paper. Two series of samples were prepared: samples without fibers and those with the addition ...
New surface characterization tools for alumina based refractory material exposed to cavitation - Image analysis and pattern recognition approach
(Elsevier Science Inc, New York, 2018)
The aim of this study was to examine the influence of cavitation erosion on the morphology of defects formed on the surfaces of alumina-based materials. The alumina-based samples were exposed to cavitation erosion for 42 ...
Microstructure and cavitation erosion performance of nickel-Inconel 718 composite coatings produced with cold spray
(Elsevier Science Sa, Lausanne, 2020)
The cold spray technique was employed in this study to produce pure nickel (Ni) and nickel-Inconel 718 powder deposits on duplex stainless steel substrates. High quality coatings were manufactured using nitrogen as the ...
The influence of alumina crystal structures on the morphology and surface erosion of PMMA composite materials exposed to cavitation testing
(Elsevier Science Sa, Lausanne, 2019)
Composites are materials that reach many users and therefore, it is necessary to correlate the properties of every component on the behaviour of the material. Alumina is used as reinforcement with the aim of improving ...
Synthesis and characterization of porous tungsten carbide with added tungsten silicides
(Elsevier Sci Ltd, Oxford, 2018)
Porous materials made of commercial tungsten carbide (WC) with the addition of thermally obtained tungsten silicides (WSi2 and W5Si3) were made. The main research's contribution is firstly finding optimal conditions for ...
Comparison of cavitation erosion behavior of cordierite and zircon based samples using image and morphological analyses
(Elsevier Science Bv, Amsterdam, 2018)
In this study the resistance of cordierite and zircon to the cavitation erosion was investigated with the aim of possible spreading their application. Cavitation erosion test was applied using standard ultrasonic vibratory ...
