確にされている。 Conventionally, this type of adhesively bonded metal material has mainly been tightened using plasma spray, flame spray, etc. or bolts, so there have been problems such as peeling and flapping at the bonded surface during high temperature use or thermal shock. . It has been clarified that the main cause of this problem is the difference in thermal expansion coefficient between the ceramic layer and the metal member.

により詳細に説明する。 The present invention solves these conventional problems by laminating a ceramic layer with a medium coefficient of thermal expansion between the surface ceramic and the base metal member to gradually compensate for the difference in coefficient of thermal expansion. It was designed to be smaller. An embodiment of the present invention will be described in detail below with reference to the drawings.

ようにすればよい。 In the figure, 1 is a metal member made of aluminum or an aluminum-based alloy, or iron or an iron-based alloy, and layers 2, 3, 4, and 5 of ceramics with adjusted thermal expansion coefficients are placed on the surface of the metal member 1 for thermal expansion. The ceramic layer is made by stacking layers with successively smaller coefficients on the outside, and the ceramic layer is made of a soluble Cr compound that is turned into ceramic by heating and firing, such as a concentrated aqueous solution of H 2 CrO 4 containing Al 2 O 3 , SiO 2 , Ceramics that are composed of one or more mixed compositions of metal oxides such as Cr 2 O 3 , ZrO 2 , TiO 2 and Mn powder and have a high coefficient of thermal expansion have a high Mn content and a high coefficient of thermal expansion. Smaller ceramics have compositions in which the Mn content decreases successively. The final ceramic layer may not contain Mn.

There is an effect that can be prevented.
