Title:
REPAIR METHOD AND REPAIR MATERIAL
Document Type and Number:
WIPO Patent Application WO/2015/105089
Kind Code:
A1
Abstract:
Provided is a repair method in which a material that is capable of bonding at a relatively low temperature is used as a repair material in a repair section and a repair that exhibits excellent sealing properties and durability even when used under a high-humidity and high-temperature environment is performed by a simple operation. The repair method includes a step in which a damaged part (DP) of a member to be repaired (10) is covered with a repair material (303) and a step in which the repair material (303) is heated to a predetermined temperature. The member to be repaired (10) comprises a first metal such as Cu or the like at least on the surface thereof. The repair material (303) comprises a second metal such as Sn or the like. Heating causes integral bonding between the surface of the member to be repaired (10), an intermetallic compound that has a higher melting point than the melting point of the low-melting-point metal of one of the first metal and the second metal, and an alloy layer. Heating also causes a Cu-Ni alloy (high-melting-point metal) powder that is included in the repair material (303) to react with Sn (low-melting-point metal) powder and thereby create a Cu-Ni-Sn alloy layer (37) that is a high-melting-point reaction product.
