of Mechanical Engineering, Universiti Teknologi Malaysia, 81310 Johor Bahru, Johor, Malaysia; 2. Department of Chemical and Biomilecular Engineering, Corrosion Engineering Program, The University... microscopy (SEM) 1 Introduction High chemical activity and poor corrosion resistance of Mg and its alloys limit their biomedical applications in corrosive environments. Corrosion resistance of Mg and its......
poor due to the presence of ultrafine particles and resultant huge consumptions of chemical reagents [24, 25]. As a matter of fact, the optimum sizes of coal particles for flotation are in the range... by slicing, lapping, polishing, and then using deionized water, alcohol and deionized water to wash it sequentially, and at last drying the surface by nitrogen. Glass fiber with a 10 mm-diameter magnetic......
in pure material. These techniques include chemical vapor deposition [12-14], rapid solidification [15,16] and mechanical alloying [17-21]. In addition toextending the limit of solubility... the accuracy of the sample temperature. The sample surfaces were finely polished with different grit sand papers starting with a coarse and gradually to fine polishing using the colloidal silica solution......
cases of a mechanical character, less often mechanical, combined with the chemical interaction of the surrounding medium [1]. The possibilities of application of some materials are reduced because of wear...-chemical treatment of metals and alloys. During LSA, the alloying elements (metallic and non-metallic elements, carbides, oxides, nitrides etc.) are mixed with substrate material. The intensive melting......
and polishing, controlling parallelism within ±0.05 mm and the surface flatness within ±0.02 mm. Samples of similar wave velocity were selected, numbered and heated to the designed temperatures... for a rated power of 4 kW and a maximum temperature of 1050 °C, mainly contains a high-temperature furnace and temperature controller. And the static experiment could be carried out by an electro......
and Protection of Oil/Gas Facility Materials, China University of Petroleum-Beijing, Beijing 102249, China; 3. School of Mechanical and Chemical Engineering, The University of Western Australia, Perth, WA... measurement, mechanical polishing with colloidal silica was carried out to remove the residual stress layer for each sample, and the grain orientation map was obtained at a mapping step of 0.1 μm......
welding; microstructural characterization; corrosion resistance; electro- magnetic interaction 1 Introduction Aluminium alloys (AA) are versatile materials used for common and specific applications... microstructural transformation that reduces the mechanical and chemical characteristics of the AA welded joints [6]. The main problem in fusion welding of Al alloys is the porosity formation within the weld......
chemical activity of titanium and its alloys, oxygen would be absorbed rapidly by the exposed surfaces of titanium alloys at temperatures above 600 °C, resulting in the formation of oxygen-rich layer (ORL... were chosen to discuss the effect of α phase content on the thickness of ORL after thermal exposure. The chemical compositions of TA15 and TC4 alloys are Ti-6.23Al-1.42Mo-2.32V-1.86Zr......
determined using a Malvern Mastersizer S2000 laser particle size analyzer. From this figure, 80% of tailings are coarse grains (d >75 μm). The chemical composition of the tailings was analyzed using...). Table 1 Chemical compositions of Dongan Xinlong Mine tailings (wt.%) The preparation of C50WG, C100, and C100WG specimens are as follows. The principal paste was thoroughly stirred......
Materials and equipment 2.1 Work part and cutting tool materials Orthogonal cutting tests were performed on the cylindrical block of the A286 superalloy.The chemical compositions of work part in mass..., notch, diffusion, chemical erosion, etc. [42]. Abrasion and adhesion mechanisms are the main wear modes that appear during machining high toughness materials such as superalloys [43]. The adhesion......
