Title:
LINING METHOD OF CU ALLOY
Document Type and Number:
Japanese Patent JP2563065
Kind Code:
B2
Abstract:

PURPOSE: To make the execution method simple and to enable an automatic treatment by laying a Cu alloy part on an iron base material, heat-melting it in a vacuum furnace and melt-joining both.
CONSTITUTION: A part (e.g. a cylinder) made of the iron base material 10 with a part to be lined with Cu alloy made into a mold shape and the Cu alloy member 12 (e.g. a Cu alloy round bar) are defatted and cleaned and then the Cu alloy round bar is laid on the mold part 16 to be inserted into the vacuum furnace. The Cu alloy member was heated under the reduced pressure, and then it is melted after the furnace pressure was raised, and the Cu alloy is melted on the iron base material 10 and joined with it. After heating under high vacuum of ≤4×10-2Torr, inert gas is filled to make the furnace pressure to 30-2300Torr and melt the Cu alloy also. Thus, the working without a flux can be performed and the working environment can be kept clean.
