    摘要： A device for burnishing and smoothing metal parts, particularly suitable for use in mechanical-galvanic processes, comprising a main body having a fastening disc to which guides are radially coupled and the body of which includes at least three mobile propelling systems which are actuated by electro-mechanical means and move in a synchronized concentric manner, approaching and moving away from the central point and acting on a rotating frame from equidistant angles. The frame is configured to secure pieces to be treated and it also has a detachable head that is disposed centrally above a cylindrical tank. The propelling systems, provided with brushes, move from an open position in which they remain separate from one another and at a distance from the center, into a closed position in which they are joined to one another in the center of the tank, coming into contact with the structure containing the parts to be treated.

    摘要： There is provided a shape memory alloy wire with a length of polycrystalline shape memory alloy having an alloy composition including at least one member selected from the group consisting of Cu in at least 10 wt. %, Fe in at least 5 wt. %, Au in at least 5 wt. %, Ag in at least 5 wt. %, Al in at least 5 wt. %, In in at least 5 wt. %, Mn in at least 5 wt. %, Zn in at least 5 wt. % and Co in at least 5 wt. %, and having a martensite crystal structure consisting of one of 2H, 18R1, M18R, and 6R. The length of polycrystalline shape memory alloy has a cross sectional wire diameter greater than 1 micron and less than 500 microns, an oligocrystalline morphology including polycrystalline grains that span the wire diameter and a wire surface with a surface roughness that is no greater than about 100 nanometers.

    摘要： A method of electrolytically polishing Fe-, Co-, and Ni alloys, particularly nickel superalloys, wherein at least one fluorine compound is mixed into the electrolyte, which electrolyte is based on a strong acid and is further comprised of at least one weakly polar organic compound and a fluorinated surfactant. The preferred fluorine compound is HBF.sub.4, added the amount of 5 to 40 vol. %. Other fluorine compounds which perform well are ammonium bifluoride, HF, and sodium fluosilicate.
