Abstract

Carbon samples heat-treated at different temperatures of 1273 to 3273 K were bonded to nickel in the solid state in a vacuum using an RF induction furnace. The bending and shearing strengths of the joints were investigated. The feasibility of disbonding of the joints was investigated by heating in a vacuum. The fracture surfaces for the joints were also observed using a scanning electron microscope. Based on the results, the effects of the heat treatment of carbon on the interface strength of a joint were examined. With increasing heat treatment temperature, the joint strength of carbon to nickel is improved. Utilizing this property, the heat treatment of carbon is performed to adjust the interface strength of a joint. Moreover, by the selection of carbon materials heat-treated at a specific temperature (2023 or 2123 K), the design of the joining system with both bonding and disbonding properties is feasible.
