One or more of powder.
For three kinds above of each of the mixed powder, it is added to form the pitch of the state of paste (such as from petroleum
50 DEG C~150 DEG C of pitch of purification), it is kneaded in kneading machine to as paste shape.Can be used tar (for example,
The tar of the by-product obtained when producing coke from coal) pitch is replaced, both pitch and tar also can be used.
Above-mentioned three obtained like that kind paste shape object is subjected to extrusion molding respectively.Firstly, paste is put into extrusion appearance
It in device, is squeezed out with plunger, the shape of extrudate can be circle, or rectangular.The needle coke of the extrudate exists
It is aligned on one direction.
Above-mentioned three obtained like that kind extrudate is subjected to once-firing at 1000~1500 DEG C, obtains solid.
The once-firing can carry out at 1000~1500 DEG C in non-oxidizing atmosphere.
Thereafter, pitch impregnation is carried out to above-mentioned each solid or tar is impregnated with, repeated multiple (such as 3~6 times) and exist
The once-firing process being burnt at 1000~1500 DEG C.Above-mentioned multiple once-firing process surpasses by volume in solid component
Terminate when having crossed 80%.Solid component be 80% or less when, in subsequent process using melting metal forging method make aluminium or
The thermal expansion of the important physical property value, direction i.e. orthogonal with direction is squeezed out of complex after aluminium alloy pressurization impregnation becomes larger, thus
Not preferably.
Particularly, in the case where LED is encapsulated, need to become the thermal expansion system with the gallium of the principal component as LED
Several 7ppm close thermal expansion.
Three kinds of extrudates of the once-firing obtained like that above are finally burnt at 2500~3000 DEG C respectively.?
It can be to be carried out in non-oxidizing atmosphere in the atmosphere.By the final firing, the elements such as silicon, aluminium, iron disappear or exclude, but
Titanium, zirconium, hafnium, tantalum, niobium element are remained in graphite in the form of carbide.
In the case where using cheaper oxide raw material without using carbide raw material, 1300 DEG C are heated in carbon
When above, strong element also dissociates into oxygen and becomes carbide with the affinity of carbon.
When M is set as metallic element (Ti, Zr, Hf, Ta, Nb), become MO+C → MC+CO.The reaction of oxygen occurs for O, therefore
It is not needed instead using carbide as starting material.In addition, metal also easily becomes carbide in above process certainly.Cause
This, also allows using metal powder, also allows simultaneously and with carbide, oxide, metal.
Carbide, oxide, metal each powder granularity it is preferably as described above, average grain diameter be 20 μm or less.Grain
When spending big, the big carbide of hardness is unworkability in obtained complex, therefore brings the evils such as the service life for making tool shortens,
It is thus not preferred.
By making each formed body of the above carbon-to-carbon compound obtained like that be impregnated with aluminum or aluminum alloy, this embodiment party can be obtained
Aluminium-graphite-carbide complex of formula.
In the mold for being previously heated to 200~350 DEG C, it will warm up 650~750 DEG C of above-mentioned each formed body configuration and exist
Defined position, casting remain 650~800 DEG C aluminium molten metal or aluminium alloy molten metal, plus-pressure 50~
Melting metal forging is carried out under 100MPa.
The composition of the aluminium used at this time be preferably 1000 systems of JIS extension aluminium alloy, 2000 systems, 3000 systems, 4000 systems,
6000 systems, 7000 systems, in addition, AC1, AC2 of JIS aluminum casting object alloy, AC3, AC4, AC8, AC9, ADC1, ADC3, ADC10,
ADC12, ADC14 etc. are also suitable.
