and efficient technique of slurry preparation. 2.2 Material and procedures The experimental material used in the study was a commercial A356 cast aluminum alloy with a specific chemical composition (wt.%) of 7.2... Positions A and B of the casting, as shown in Fig. 3(d). After the coarse grinding, fine grinding, and polishing, the samples were eroded with a 0.5 vol.% hydrofluoric acid solution. A Neophot......
studies. Recently, the electroosmotic method has attracted extensive attention in academic and engineering circles with the breakthrough made by researchers in the field of electro-kinetic geosynthetics... the S2 status earlier, it is considered to result from the fact that soil in the affected area around the anode tends to be associated with a more violent chemical reaction and the effect......

The Fourth Academy of CASIC, Beijing...) with Cu Kα radiation. The bulk sintered HEA samples were etched using a solution of dilute aqua regia after polishing. The morphology and microstructure of the samples were characterized using an FEI......
-treatment (e.g., plasma polishing, mechanical polishing, electro-polishing and sandblast [11]) to meet the demand of the surface quality and dimensional accuracy. According to the working principle of SLM... reinforcements can react with the Al matrix or some elements of reinforcements can diffuse into the matrix, thereby changing the chemical/physical properties of the Al matrix. In addition, the particulate......
with epoxy-resin. After polishing, the samples were etched with a 10% hydrofluoric acid in water enchant for 30-45 s. After metallographic process, the microstructures of the samples were revealed.... The quantitative chemical composition analyses of η-Zn matrix and η-Zn+a(Al) were carried out by using an energy dispersive X-ray analyzer (EDX) and the results are given in Fig. 3. According to EDX......

available Al6061 aluminium alloy plate of 5 mm in thickness was used as a substrate or base metal (BM) in the present study. Table 1 presents the chemical composition of the base Al6061 alloy. GNP (United... and morphology of various raw materials are illustrated in Fig. 1. Table 1 Chemical composition of base AA6061 aluminium alloy (wt.%) A groove of dimensions 3 mm × 3.5 mm (width × depth) was fabricated......
hardness (up to 2500 HV) was formed. The promising effects characterized the electro- chemical boriding process of Inconel 600 alloy [11]. Although, short process duration was used (in range from 5 to 15.... The objective of investigations was to determine the influence of the chemical and phase compositions of borided layer on its mechanical properties. The nanoindentation was carried out using Berkovich diamond......
. Then, they were sequentially ground with 60#, 600#, 1000#, 2000# and 5000# SiC paper, and finally, polished with 3.5 μm diamond paste. After polishing, the specimens were degreased with ethanol, rinsed......
-Li alloys. 2 Corrosion behavior of Mg-Li alloys Mg and its alloys are prone to severe corrosion in humid air, sulfur atmosphere, and seawater due to their active chemical properties and the porous... is of significance to the practical applications. In general, the corrosion behavior of Mg-Li alloys depends on several factors, including composition and microstructure of alloys, physical and chemical properties......
