Abstract
The present invention relates to a process in which a metal or metal alloy is thermal spray coated onto a base alloy material prior to hot working. More specifically, the invention relates to the use of plasma coating of titanium over a titanium alloy plate for improved hot workability. This combination allows the crack-sensitive base alloy to be rolled with a minimum of surface and edge cracks. In addition, by using a plasma sprayed titanium coating there is a reduction in the roll force required to reduce the material during the hot working process.
