Abstract

1417367 Chromium carbide layer formation TOYOTA CHUO KENKYUSHO KK 10 April 1974 [12 April 1973 22 June 1973] 15991/74 Heading C7F A chromium carbide layer is formed on the surface of iron, ferrous alloy or cemented carbide (WC + Co) articles by heating in a molten bath of a chromium halide dissolved in a bath of boric anhydride and/or at least one borate i.e. Na 2 B 4 O 7 , K 2 B 4 O 7 . The article must have at least 0.05%C present in the surface, and is cleaned prior to immersion in the bath for between 10 minutes to 30 hours at 700‹C to 1100‹C, depending on carbide layer thickness required. Treatment temperature should be below the transition temperature of the article, and both temperature and viscosity may be lowered by the addition of alkali metal chlorides or fluorides, NaCl, KF, oxides P 2 O 5 , hydrates, sulphates carbonates or nitrides, Treatment may be in air or an inert atmosphere, and the halide content of the bath is 1-50%, preferably 5%. Examples of tool steels and cemented carbides treated using CrCl 3 and CrF3 are given.
