Title:
METHOD FOR JOINING ALUMINA CERAMICS TO ALUMINUM
Document Type and Number:
Japanese Patent JP2729751
Kind Code:
B2
Abstract:
PURPOSE: To provide a joining strength attaining the strength of a base metal by interposing a specific aluminum alloy material between an alumina ceramic material and an aluminum material and thermally joining both.
CONSTITUTION: A TiH paste, as necessary, is screen printed on an expected joining surface of an alumina ceramic material and metallized at 900-1000°C in a vacuum or a Cu paste is screen printed thereon and metallized at 900-1200°C in the vacuum. An aluminum alloy material composed of 9.0-11.0wt.% Si, ≤0.8wt.% Fe, ≤0.3wt.% Cu, ≤0.05wt.% Mn, ≤0.05wt.% Mg, ≤0.1wt.% Zn, ≤0.2wt.% Ti and Al is interposed in a joining surface of this alumina ceramics, material and an aluminum material composed of ≤0.6wt.% Si, ≤0.7wt.% Fe, ≤0.2wt.% Cu and ≤2.0wt.% Mn, heated at 590-600°C in a vacuum or an inert atmosphere and joined to afford this joined body having ≥200MPa joining strength.
