Title:
PRODUCTION OF CERAMIC-METAL BONDED MATERIAL
Document Type and Number:
Japanese Patent JP3176460
Kind Code:
B2
Abstract:
PURPOSE: To prevent galling in insertion and to provide a ceramic-metal bonded material exhibiting a low residual stress after insertion and bonding under pressure and capable of maintaining a strong bonding force.
CONSTITUTION: In production of a ceramic-metal bonded material by applying a lubricant to the bonding surface 5 between a ceramic member 2 and a metal member 3 and inserting the ceramic member into a depression part or a through hole of the metal member under pressure and bonding to each other, the above- mentioned lubricant is composed mainly of a carboxylic acid, a carboxylic acid salt, a carboxylic acid derivative or a substituted carboxylic acid and the above-mentioned insertion between both the members is subsequently carried out under a condition where the surface pressure Pm generated between the bonding surfaces and the insertion length L satisfy formula 10≤Pm≤100 [kgf/ mm2] and formula 30≤Pm≤L [kgf/mm]. A heat treatment is subsequently applied thereto until the coefficient of friction of the lubricant-applied parts when being pulled out becomes higher than the coefficient of friction at a point of time of insertion.
