METHOD OF PLATING INSIDE WALL OF NARROW TUBE AND NARROW TUBE MANUFACTURED BY THE SAME PLATING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a method of plating the inside wall of a narrow tube having a miniaturized diameter and a composite plating method with a dispersion of an insoluble ultrafine particle, an ultra dispersed diamond (UDD) or the like. SOLUTION: A plated film on the inside surface of the narrow tube is formed by arranging an inlet opening part for a plating solution in the narrow tube to oppose to the flow direction of the plating solution and making the plating solution forcibly flow into the inside of the narrow tube to keep the concentration of the plating solution existed inside and that existed outside the narrow tube to be equal. As a result, a normal and uniform plated and composite-plated film is formed on the inside surface of the narrow tube. COPYRIGHT: (C)2007,JPO&INPIT
