“…It is known that Cu, Pb, Sn and Bi little soluble in α-Fe at room temperature, solubility Ga reaches 17at.%. Authors of [12,29] analyzed effects of macroscopic and microscopic regulating of wetting of austenitic steel liquid Ga, Cu and Cu90Ga10. Liquid gallium spreads on steel surface, resulting in formation of intermetallic phases FeGa3 and Fe14,5Ga12.…”

“…Substrate from steel of brand St3 was used in all experiments of wetting. Smelting of HEAs and experiments of wetting were performed in pure helium under a pressure of 10 5 Pa. Spot diameter of wetted surface D and wetting surface angle θ we measured by standard technique "big drop" [23][24][25][26][27][28][29]. Dependences on temperature and dependences on time were measured.…”

We present a result of a study of reactive wetting of surface of low carbon steel by liquid alloys CuSnBiPbGa, CuSnBiPbIn and CuSnBiInCd of equiatomic composition. Dependences of contact angle and spot diameter of wetted surface on temperature and time were studied. Liquid alloy CuSnBiPbGa begins wetting of surface of steel at 900 °C; spreading rate at higher temperatures increased by 8 times. Liquid alloy CuSnBiPbIn begins wetting surface of steel at 780°C, but spreading speed is almost unchanged with the further increase in temperature. Liquid alloy CuSnBiInCd begins wetting of surface of steel at a temperature of 570°C, and spreading is in a flash in nature. We studied microstructure and chemical composition of diffusion layers, formed at the spreading of liquid alloys of equiatomic composition CuSnBiPbGa, CuSnBiPbIn and CuSnBiInCd on steel surface. In all experiments at boundary with substrate a ductile transition layer of a solid solution of iron-based is formed. The thickness of diffusion layer side depends on the alloy composition. The widest diffusion layers formed for alloy CuSnBiInCd, and the most narrow - for alloy CuSnBiPbGa. We detected in segregations of copper and gallium atoms for bimetallic sample "CuSnBiPbGa+steel", of copper and tin atoms for samples "CuSnBiPbIn+steel" and "CuSnBiInCd+steel" in diffusion layers. The results of these studies have significance for the design of soldering technology and application of protective coatings on steel products.

“…The low surface tension of pure Ga has already been shown to minimize the surface tension of a CuGa 10 alloy compared to pure Cu. 7 Nano-Cu-Ga alloys/polymer composites have potential applications in the fields of conductive thin film. As we all know, the fabrication principle of nano-alloys/polymer nanocomposites is the interaction between polymeric matrix and metal nanoparticles (NPs), for instance, hydrogen bond, static electricity, charge-transfer, 8,9 and so on.…”

In this article, the copper-gallium (Cu-Ga)/poly(acetoacetoxyethylmethacrylate-styrene) (P(AAEM-St)) nanocomposites were prepared and characterized according to the following steps. Firstly, Cu-Ga/P(AAEM-St) nanocomposites were prepared via emulsifierfree emulsion with metal Ga in copper acetate solution and copolymerization of St and AAEM monomers by ultrasonic under nitrogen protection. Secondly, the constituent, i.e., the interaction between metal nanoparticles and polymeric matrix of the composites, was tested by various techniques including X-ray diffraction, transmission electron microscopy, thermogravimetric analysis, Fourier transform infrared spectroscopy, and Xray photoelectron spectroscopy. Cu, Ga, and CuGa 2 phase in polymeric matrix were identified by above techniques. It was revealed that the interaction is a chemical force between Cu atoms belonging to metal nanoparticles and C¼O associated with acetoacetoxy from polymeric matrix.
