Title:
CLAD WIRE TYPE VAPOR DEPOSITION MATERIAL AND ITS MANUFACTURING METHOD
Document Type and Number:
Japanese Patent JP3518740
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a vapor deposition material capable of depositing, by a single vapor-deposition operation, a deposit film where a vapor-deposition composition in the initial stage of vapor deposition is different from that in the final stage of vapor deposition and the dispersion of film composition in the initial stage of vapor deposition is minimized.
SOLUTION: In the clad wire type vapor deposition material in which high vapor pressure metal is used as a core material and a low vapor pressure metal is used as a sheath material, the vapor pressure of the core material is lower than that of aluminum and the wall thickness deflection of the sheath material is ≤2.0. The core material is clad with the sheath material, which is wiredrawn, to the prescribed outside diameter and length. The end face of the resultant nearly cylindrical vapor deposition material is chamfered. By this method, the material can be easily subjected to automatic feed into a vapor deposition mechanism by means of a parts feeder, etc.
