As one kind preferably, described additive doping depth in main body is not more than 0.5mm.
As a kind of preferably, described additive is uniformly distributed in main body top layer or from outward appearance to inner essence successively decreases (i.e. with mixing
The increase of miscellaneous depth, in same depth, the content of additive reduces).
In the present invention program, the surface structure of alloy is only entrained in it is achieved that low-mix using the additive of low-doped amount
The stable lifting of the high temperature resistant and mechanical performance under miscellaneous amount, decreases the content in alloy components internal additives simultaneously, and reduces
The impact of interior microscopic form.And under high temperature form, when there is carbon fiber in additive, its electric conductivity is strengthened, and drop
The impact to alloy self-resistance for the low high temperature, the conductive capability of lifting high temperature section.
As one kind preferably, when being carbon fiber, ceramic fibre, titanium nitride, Calcium Carbonate in described additive, its surface is all pre-
It has been initially formed intermediate layer, described intermediate layer includes at least one of which aluminum middle layer.
As one kind preferably, in described intermediate layer, the thickness of every layer of aluminum middle layer is 0.1-0.4 micron.
As a kind of preferred, in described intermediate layer, between adjacent two aluminum middle layers, also include copper transition zone.Intermediate layer
Copper/constructed of aluminium, to improve the histocompatibility of additive, simultaneously works as controlling the effect of cost.And do not affect the device pointed out
Be welded to connect performance.
As one kind preferably, the gross thickness in described intermediate layer is 2-3 micron.
Control to total interlayer thickness and each thickness degree in the present invention, with adapt to additive to high temperature resistance and
The compatibility to alloy structure, thus forming consistent and effective phase composition part in interpolation part, thus in alloy structure table
Layer forms that high temperature resistance is good and the exsertile organizational structure of mechanicalness, thus lifting the heat stability of alloy, machine on the whole
