Document Type and Number:
Japanese Patent JP6823287
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method for forming a low resistance or a porous structure of tin alloy at low energy cost per formed object using a low power laser and galvanic substitution reaction.SOLUTION: Provided are a method for forming a low resistance or porous structure of a metal alloy containing tin and a formed structure. Using a mixed material of a low-melting point metal powder containing tin and a high-melting point metal powder, a metal powder fixing layer adhered to a base material is formed by melting the low-melting point metal by laser irradiation. Immobilized tin is metal-exchanged by galvanic substitution reaction.SELECTED DRAWING: Figure 1
