Description
Technical field
The present invention is a kind of metal composite high-temperature resistant membrane material, and in particular to a kind of inorganic metal composite hydrophobic is thin
Film.
Background technology
Existing organic coating construction is simple, but environmental pollution is serious, there is a great harm for health, and is not resistant to be higher than
350 DEG C of high temperature；Inorganic coating, difficulty of construction is larger, and change in size is big, differs larger with thermal expansion metal coefficient, is not easy to adhere to
Securely, high temperature is easy to crack, and electric conductivity is poor；Plating production process is big to personnel and environmental pollution damage, to piece surface requirement
Height selects harshness to basis material, and hardness is not high enough, easily scratches.
Invention content
The defects of present invention is in order to solve existing electroplated layer, organic coating, inorganic coating provides a kind of inorganic metal and answers
Close hydrophobic membrane.
The present invention adopts the following technical scheme that realization：
A kind of inorganic metal composite hydrophobic film, it is characterised in that be made of the raw material of following weight ratio：Aluminium powder 13 ~
17%th, lithia 1 ~ 5%, titanium valve 43 ~ 47%, carbon dust 8 ~ 12%, iron powder 15 ~ 20%, silica 8 ~ 12%；
Its production craft step is：Silica, titanium valve, carbon dust, iron powder, which mix to be put into stir in high temperature furnace in proportion, to be added
Heat obtains melt, is then cooled to 2000 DEG C, be proportionally added into aluminium powder in the melt, lithia stirring is melted to 2600 DEG C of meltings
Melt, make melt mixed uniform, then proceed to be warming up to 2400 DEG C of stirrings, make melt dispersion uniform, cooling stirring to 500 DEG C~
600 DEG C make melt become uniform powder；It is auxiliary agent with boron, argon gas is protection gas, and workpiece is put into 500 DEG C~600 DEG C high temperature furnaces,
It carries out workpiece surface spraying and forms inorganic metal composite hydrophobic film.It is molten to 500 DEG C~600 DEG C formation that auxiliary agent is cooling stirring
The 10% of body powder.
The present invention makes silica, titanium valve, carbon dust, iron powder fully melt at 2600 DEG C first, in order to prevent aluminium powder, oxidation
Lithium boils at 2500 DEG C or more, is cooled to 2000 DEG C, adds aluminium powder, lithia, then it is further heated up to 2400 DEG C, makes to melt
Physical efficiency is preferably melted and is uniformly dispersed.Being eventually adding auxiliary agent reduction melt fusing point makes melt more readily dispersible uniformly.
Inorganic metal composite hydrophobic film of the present invention, is sprayed at metal surface, has high temperature resistant, the corruption of resistance to environment
The advantages such as erosion, hydrophobic, high, highly polished, being basically unchanged of size of hardness, alternative parcel plating technique solve galvanic waste
Pollution to environment（Such as waste discharge）, it is time saving, saving of labor, laborsaving.The present invention is used in air speed pipe surface, with obvious effects, and resistance to 550
DEG C high temperature, for conductive, hardness than plating floor height, environmental corrosion resisting effect is good.This material has not been reported both at home and abroad at present, it is mainly solved
The certainly protection question of metal surface.
Inorganic metal composite hydrophobic film of the present invention is compared with other coatings：
