Abstract
Official abstract text for this publication.
A conductive member includes: a conductive member main body portion that has Vickers hardness equal to or greater than 100Hv and is made of copper or a copper alloy; and a film layer that is formed on an end face of the conductive member main body portion and is made of aluminum or an aluminum alloy. The film layer is formed by accelerating a powder material of aluminum or an aluminum alloy together with a gas heated to a temperature lower than a melting point of the powder material, spraying the powder material still remaining in a solid phase onto an end face of the conductive member main body portion, and causing the powder material to be deposited thereon.
First claim
Opening claim text (preview).
1 . A conductive member comprising: a conductive member main body portion that has Vickers hardness equal to or greater than 100Hv and is made of copper or a copper alloy; and a film layer that is formed on an end face of the conductive member main body portion and is made of aluminum or an aluminum alloy, wherein the film layer is formed by accelerating a powder material of aluminum or an aluminum alloy together with a gas heated to a temperature lower than a melting point of the powder material, spraying the powder material still remaining in a solid phase onto an end face of the conductive member main body portion, and causing the powder material to be deposited thereon. 2 . The conductive member according to claim 1 , wherein the conductive member is used as an electrode terminal for a battery. 3 . The conductive member according to claim 1 , wherein the conductive member is used as a negative terminal for a battery, the negative terminal being connected to a positive terminal of another battery via an aluminum made bus bar. 4 . A method of manufacturing a conductive member, the method including a step of forming a film layer by: accelerating, towards an end surface of a conductive member main body portion having Vickers hardness equal to or greater than 100Hv and made of copper or a copper alloy, a powder material of aluminum or an aluminum alloy together with a gas heated to a temperature lower than a melting point of the powder material; spraying the powder material still remaining in a solid phase onto the end face of the conductive member main body portion; and causing the powder material to be deposited thereon. 5 . The method of manufacturing the conductive member according to claim 4 , the method including, after the formation of the film layer, an annealing step of making the Vickers hardness of the conductive member main body portion to 60 to 80Hv. 6 . An electrode terminal for a battery, comprising: a conductive member including: a conductive member main body portion that has Vickers hardness equal to or greater than 100Hv and is made of copper or a copper alloy; and a film layer that is formed on an end face of the conductive member main body portion and is made of aluminum or an aluminum alloy, wherein the film layer is formed by accelerating a powder material of aluminum or an aluminum alloy together with a gas heated to a temperature lower than a melting point of the powder material, spraying the powder material still remaining in a solid phase onto an end face of the conductive member main body portion, and causing the powder material to be deposited thereon. 7 . The electrode terminal according to claim 6 , wherein the electrode terminal is a negative terminal that is connected to a positive terminal of another battery via an aluminum made bus bar.
