In addition, the case has a good lubricant retaining property, the removing property (stripping property) of the battery case which is an important factor for the DI or DTR formability can be improved.

Abstract: A method is provided for bonding a ceramic thermal barrier coating to a nickel or cobalt based superalloy substrate for use in high temperature applications such as gas turbine engines. The method comprises roughening the superalloy substrate itself to produce a surface roughness, preferably from 100 to 350 microinches Roughness Average (RA).
