Experimental subjects: ceramic material made from disc brake sheet on the market, embodiment 1, ceramic material and implementation made from embodiment 2
Ceramic material made from example 3, is respectively divided into 4 groups: control group, experimental group 1, experimental group 2 and experimental group 3, and every group 40 pieces.
Test method: each group is carried out respectively using tensile-strength tester, yield strength testing machine and shear testing maschine
Test.
Experimental result is as follows:
By being compared to 3 groups of experiments, it is seen that the mechanical property of experimental group is quite outstanding.
It, can be with the beneficial effects of the present invention are: there is outstanding heat-transfer capability containing a large amount of nitridation aluminium component in surface layer
Whole surface effectively is transferred heat to, so that being uniformly heated, so that heat is preferably transmitted in air, while face
Mechanical property is promoted containing scandium oxide in ingredient in layer, avoids the embrittlement phenomena being also easy to produce when long-term work under high temperature, and
It is whole that there is outstanding mechanical property again.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
The change or replacement expected without creative work, should be covered by the protection scope of the present invention.
