Abstract
PURPOSE:To prevent fine grains from coagulating in a plating bath, by applying vibration with ultrasonic frequency to the inner part of a plating bath at the time of forming a corrosion-resisting plating film of Zn or Zn alloy in which wear resistance is improved by forming the fine grains of ceramics, etc., into eutectoid on the surface of a steel sheet. CONSTITUTION:At the time of applying electroplating with a corrosion-resisting plating film consisting of Zn or Zn alloy of Zn-Fe, Zn-Ni, Zn-Cr, Zn-Fe-Ni, Zn-Fe-Co, or other types to the surface of a steel sheet, the fine grains of 1nm-1mum diameter of ceramics, such as SiO2 and Al2O3, metal, such as Cr, carbide, etc., are added in 1-400g/l concentration to a plating bath, by which a plating film in which the above fine grains exist in the form of eutectoid is formed and the wear resistance of the plating film is improved. At this time, in order to prevent the above fine grains from coagulating in the plating bath 4, an ultrasonic vibrator 2 is provided into the plating bath 4 in a plating tank 3 and ultrasonic waves of 19KHz-2MHz frequency are applied to the inner part of the plating bath 4 from an ultrasonic generator 1, by which the fine grains in the plating bath can be prevented from coagulating and uniformly and dispersedly precipitated in the plating film.
