Cavitation erosion resistance of steels is important in many applications. The investigation such resistance, under different conditions, should be very useful. tests were carried out on carbon steel AISI-1045 using an ultrasonic induced cavitation facility. pits and their effect the localized corrosion investigated detail three corrosive media: distilled water, tap 3% NaCl water. results SEM indicated formation types cavitating specimen surfaces: pits, erosion-corrosion pits. have shapes,...
In the present study mechanical milling used to form nanocrystalline structure in Al-Al2O3 powders. The microstructure of milled powders was investigated by X-r ay diffraction (XRD) analysis. It found that XRD peaks showed a significant broadening, which related grain refinement and lattice distortions. X-ray patterns were analyzed using Williamson–Hall treatment determine crystallite size strain. have been synthesized with showing higher strain an evolution finest particles. Microhardness...
Metallic foams are gaining ground as important new engineering materials.Aluminium were produced with different densities using percentages of calcium carbonate a foaming agent.The mechanical properties the foamed material tested uniaxialcompression test.Plateau stress σpl, densification strain εd and energy absorption capacity U, calculated.The obtained results show that collapse strength absorbed increase increasing density.
Electroless Nickel-Phosphorus coatings have had a lot of interest in various industries due to outstanding characteristics. Some the highlighted characteristics electroless Ni-P are superior corrosion and wear resistance. But effectiveness coating resisting cavitation damage is not studied so well clear. In present investigation, were prepared at conditions including type bath, heat treatment temperature plating solutions composition. The properties characterized using X-ray diffraction...
Abstract A spiral concentrator is a gravity concentration device. It was invented by Humphreys in 1941. Firstly, it designed and developed based on experience extensive testing of prototypes modifications. The main objective the present study simulation particulate flow more realistic solid concentrations (i. e., 15 wt.-% solids) separator. This Eulerian approach renormalization group k-∊ turbulence modeling. results focus characteristics such as velocity, distribution particulates trough....
Abstract The distribution of aniline between n ‐heptane and aqueous ammonium sulfate solutions was studied at different temperatures. activity coefficients in solutions, were determined. effect on the dissociation studied, amine salt concentrations, temperatures, using a modified method 1 .

Wear particles produced by vibratory cavitation erosion tests on 1045 carbon steels in three different corrosive media: distilled water, tap water and 3 % NaCl were analyzed. Scanning electron microscope (SEM) of wear acquired, forming database for further analysis. This study shows that there is no remarkable difference the particle size with test solution. However, frequency distribution sizes differed It highest at small water. While salt it larger (larger than 50 µm). All particles,...
