Abstract (en)
A process for removing protective coatings and/or bonding layers from metal parts, particularly gamma prime hardened nickel base alloy, solid solution superalloy, iron base superalloy, and cobalt base superalloy parts to render them brazable or otherwise bondable. The process uses a C-O-H-F atmosphere as the primary stripping material wherein the atmosphere has a H/O ratio of 10<4> or greater. The preferred source of the C-O-H-F atmosphere is thermal decomposition of a fluorocarbon resin.
