摘要： A new scanning electrochemical microscopy tip positioning method that allows topography and surface activity to be resolved independently is presented. A SECM tip is oscillated relative to the surface of interest. Changes in the oscillation amplitude, caused by the intermittent contact of the SECM tip with the surface of interest, are used to detect the surface of interest, and as a feedback signal for various types of imaging.

摘要： This invention relates to a method for producing films of semiconducting material based on the organic-inorganic metal-halide compounds with perovskite-like structure, which can be used as a light-absorbing layer in solar cells, including thin-film, flexible and tandem solar cells, as well as can be applied for optoelectronic devices, in particular, light emitting diodes. The method is comprising the following steps: (a) applying a layer of a precursor, (b) applying a layer of composite reagent, and (c) treatment of the applied layers by the reagent X2 wherein the composite reagent applied in the step b) contains a mixture of AX and X2 reagents, and the film obtained after the step b) contains the seeds of the phase with a perovskite-like structure; the reagent AX is a salt comprising cation A+ and anion X−, and the anion X− is a singly charged anion; the reagent X2 is a molecular halogen.

摘要： A method and device for laser cladding by independently heating the cladding material and the surface of the workpiece consist in formation of the series of parallel annular laser beams, possibly different wavelengths, with an adjustable distribution of laser radiation power across the annular beams. The annular beams are transformed into a series of conical beams which are separately focused along a single optical axis, along which the cladding material is fed. The device can be supplemented with a cylindrical mirror for the multipass laser radiation through the stream of cladding material with the possibility of the laser radiation return to the laser resonator.

摘要： Molybdenum is alloyed into stainless steel surface by electro-spark deposition technique. Shielding gas is used during electro-spark deposition process to minimize the oxidation of materials. Control of electro-spark voltage, frequency, capacitance, time can determine the alloying depth of Molybdenum. The alloyed surface thickness varies from 5 μm to 80 μm depending on the electro-spark deposition parameters. The alloyed surface comprises, by weight, 15 to 40% of Molybdenum, 8 to 22% of Cr, 0-15% of other alloy elements and impurities. The molybdenum alloyed stainless steel surface exhibits improvement in micro-hardness, wear resistance, and especially corrosion resistance in sodium chloride solutions. Thus, the present invention would be utilized in marine and handling of brines application, as well as in other applications which better corrosion resistance of stainless steel is desired.

摘要： One aspect of the disclosure provides an iron-based hardfacing layer which includes hard or wear resistant phases resulting at least in part from dissolution of silicon and/or boron carbide particles into a liquid iron-based metal during the fabrication process. In an embodiment, the hardfacing layer is formed by a fusion welding process in which carbide particles are added to the molten weld pool. In an example, the filler metal supplied to the welding process is a mild steel. In an embodiment, the hardness as measured at the surface of the hardfacing ranges from 40 to 65 HRC. In an example, the iron-based hardfacing layer also includes tungsten carbide particles.

摘要： Disclosed is an AMS process using a water-leachable alloy that reacts with water and dissolves, and a porous metal manufactured using the same. An AMS precursor including element groups that are selected in consideration of the relationship of heat of mixing with the water-leachable alloy composition to be subjected to the AMS process is immersed in the alloy melt, thus manufacturing a bi-continuous structure alloy. The bi-continuous structure alloy is subjected to dealloying using water, thus manufacturing the porous metal. The water-leachable alloy is a Ca-based alloy having high reactivity to water and high oxidation resistance at high temperatures, and a dealloying process thereof is performed using only pure water, unlike a conventional dealloying process performed using a toxic etching solution of a strong acid/strong base. The metal porous body has high elongation, a large surface area, and low thermal conductivity.
