DIFFUSION JOINING METHOD OF COPPER AND STAINLESS STEEL

摘要

PURPOSE:To join the joint surfaces of copper and/or stainless steel to be diffusion-joined under low pressure in short time and to obtain a joint part having good quality by forming an alloy layer having the m. p. lower than the m. p. of the joint surfaces to said surface. CONSTITUTION:An alloy layer having the m. p. lower than the m. p. of materials to be joined is formed to the joint surface of copper and/or stainless steel which is the material to be joined. The alloy layer surface is then positioned to face the adjacent members to be joined. The members are thereafter joined in a non-oxidizing atmosphere. The members are thus joined at the temp. lower than the m. p. of the materials to be joined under the low pressure in short time, by which the joint part having good quality is obtd.
