Document Type and Number:
Japanese Patent JP2016180185
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a production method of an aluminum alloy-ceramic composite, enabling the aluminum alloy-ceramic composite excellent in crack resistance and peeling resistance to be efficiently produced.SOLUTION: According to the invention, the production method of an aluminum alloy-ceramic composite is provided that comprises: a step of impregnating an aluminum alloy into a planar ceramic porous body thereby forming a planar aluminum alloy-ceramic composite base sheet having an aluminum alloy layers on both main surfaces; and a step of introducing linear defect or intermittent defect to at least one main surface of the composite base sheet and then cutting it to form the aluminum alloy-ceramic composite in which the ceramic porous body and the aluminum alloy layer are exposed on a side surface. In the production method of an aluminum alloy-ceramic composite, the ceramic porous body contains at least one of silicon carbide and graphite, ceramic filled amount is 50 mass% or more and the ceramic porous body has a thickness of 0.35 to 3.8 mm, the aluminum alloy has a content of aluminum of 70 mass% or more, the composite base sheet has a thickness of 0.5 mm to 4.0 mm and the aluminum alloy layer has a thickness of 0.01 mm to 0.3 mm.SELECTED DRAWING: None
