Abstract:
PURPOSE: A method for bonding a metal member and a ceramic member is provided to bond the metal member and the ceramic member in an atmospheric condition without an insertion metal or an adhesive. CONSTITUTION: A method for bonding a metal member and a ceramic member includes: a step of meshing or overlapping the metal member with the ceramic member; a step of placing the tool of a milling machine on a portion in which the metal member is overlapped with the ceramic member; a step of moving the tool along the portion; and a step of removing burr at a bonding surface between the metal member and the ceramic member. The metal member includes nonferrous metal and ferrous metal, and the ceramic member includes carbonized, nitrified, and oxidized ceramics. [Reference numerals] (AA) Step of meshing or overlapping the metal member with the ceramic member; (BB) Step 110; (CC) Step of placing the tool of a milling machine on a portion in which the metal member is overlapped with the ceramic member; (DD) Step 120; (EE) Step of moving the tool along the overlapped portion; (FF) Step 130; (GG) Step of removing burr at a bonding surface; (HH) Step 140
Abstract:
PURPOSE: An apparatus for friction stir welding is provided to prevent the adhesion between a binded material and a backing plate due to frictional heat by using aluminum nitride. CONSTITUTION: An apparatus for friction stir welding comprises a first member(20), a second member(22), a tool(10), a backing plate(30) and a contact plate. The first member and the second member each other adhere closely for friction stirring joint. A tool is inserted into the junction of the second member and the first member. The tool welds the first member and the second member through the friction stir. The backing plate supports the first member and the second member. The contact plate is inserted into the backing plate. The contact plate is inserted into the part corresponding to the junction of the second member and the first member. The contact plate is made of aluminum nitride.

본 발명은 마찰교반 접합 시 접합부의 최고온도 및 피접합재의 냉각속도를 조절할 수 있는 마찰교반 접합장치 및 마찰교반 접합방법에 관한 것으로, 접합 시에는 접합부에 가해지는 열을 접촉 플레이트로 흡수하고 냉각기로 냉각시킴으로써 접합 시 최고온도를 낮추어 상변태가 일어나는 것을 막고, 접합 후에는 피접합재의 냉각속도를 조절함으로써 상변태가 일어날 수 있는 재료의 상변태를 조절하는 것을 특징으로 한다.
