DEFINITION

Classification: 428/666

(under subclass 663) Subject matter in which the Group VIB metal is chromium.

SEE OR SEARCH THIS CLASS, SUBCLASS:

613, for composite materials having a "microcracked" chromium component between other components.

656, 661 and 664, to complete a search for Cr-based components.

148, Metal Treatment,

264+, for processes of reactively coating a metal substrate wherein a chromium containing liquid external agent combines with a component of the metal substrate to form a coating thereon containing a component of the metal substrate. 205, Electrolysis: Processes, Compositions Used Therein, and

Methods of Preparing the Compositions,

178+, for methods of electrolytically coating multiple layers, at least one of which is chromium, from an aqueous bath, and subclasses 283+ for coating a single Cr layer from such a bath.
