Abstract

310,812. Research Corporation, (Assignees of Fiedler, M.). April 30, 1928, [Convention date]. Coating; coating by dipping.-A metal body 'having a coating of another metal is heated by induction of a high frequency current to cause diffusion of the metals at the junction. In an example, a steel tube of 1 inch diameter and 1-16th inch thickness having a chromium coating of the thickness 0.0002 inch is passed through a coil 5¢ inches long and 1# inches in diameter having a power input of 22-23 kw. at 30,000 cycles at a rate of 0.4-0.55 inch per second. The heating current in the tube is localized by skin effect. A higher power input is necessary at lower frequencies. The coating may be carried out by electrodeposition, cold forging, dipping, spraying or painting. The heating may be carried out in air, in vacuo or in a reducing or neutral gas. Chromium plate on heating gives off sufficient hydrogen to form a neutral atmosphere. Iron may be coated first with chromium and then with cobalt before heating. A zinc base may be coated first with bismuth or cadmium and then with copper. Plates or irregularly shaped articles may be treated by the use of a flat spiral or other appropriately shaped inducing coil. The heating may be followed by a heat treatment in an ordinary furnace. According to the Specification as open to inspection under Sect. 91 (3) (a), a rapidly interrupted direct current may be used as inducing current and the invention may be applied to the case hardening of iron or steel by heating in a carburizing gas or to decarburization. This subject-matter does not appear in the Specification as accepted. Reference has been directed by the Comptroller to Specification 275,233.
