DEFINITION

Classification: 148/245

Electrically insulating coating formed which is more than mere oxide formation:

(under subclass 243) Subject matter wherein the reaction product of the metal substrate and the reactive material is claimed or disclosed as being electrically insulating and is more than the formation of an oxide, per se.

(1) Note. Processes wherein a material reacts with a metal substrate to provide a nonoxide coating are proper for this subclass.
