Abstract

811,573. Electroplating. IONIC PLATING CO. Ltd. May 18, 1956 [May 18, 1955], No. 14296/55. Class 41. [Also in Group XXV] A screw-threaded member has the threaded portion formed of steel, is formed to a diameter and pitch according to the particular standard employed, and has the threads electroplated with a protective coating comprising one or more layers of a tin-cadmium alloy or comprising alternate layers of tin and cadmium. In one arrangement an alloy layer is formed by im-. mersing the member successively in tin and cadmium electroplating baths and then subjecting it to heat treatment to alloy the tin and cadmium. A final protective film may be provided by immersing the coated member in a chromate-solution bath. The coating is sufficiently thin to require no alteration of the cooperating screwed member which is made to the same standard and, in a specific embodiment, a coating for a member comprising one 0.0001 inch layer each of tin and cadmium is said to provide equivalent anti-corrosive properties to a 0.0005 inch layer of either tin or cadmium alone.
