The preparation method of modified activated carbon fiber is：By a certain amount of activated carbon fiber and organo silane coupling agent, it is put into 35-40KHz
Ultrasound Instrument sink in ultrasonic disperse 50-60min, be uniformly mixed, be subsequently placed in 80 DEG C of drying boxes that drying to constant weight to get table
The activated carbon fiber that face is modified.
The norium is rich yttrium mixed rare earth metal or/and lanthanum rich norium.
The preparation method referenced patent application publication No. of the aluminium molybdenum niobium copper zirconium intermediate alloy be 103898386 A of CN, name
Referred to as《A kind of aluminium molybdenum niobium copper zirconium intermediate alloy and preparation method thereof》.
The granularity of the siderochrome manganese-silicon powder is 3-5 μm.
On the basis of matrix iron and modified activated carbon fiber, addition WC-TiC-Co composite nano-powders, aluminium molybdenum niobium copper zirconium
The materials such as intermediate alloy are as complex material so that the alloy of preparation has good intensity and hardness, high temperature resistant, and its compared with
Densification sintering can be achieved under low sintering temperature, and improve the uneven mixing of original various one-components；Add simultaneously
Add norium, refined crystal grain, purify crystal boundary, reduce that crystal grain is uneven to grow up so that the flowing of alloy interior tissue
Property and wellability further improve, so as to the more uniform densification of institutional framework.
Beneficial effects of the present invention：The strong steel alloy of heat of the present invention uses the base of iron and modified activated carbon fiber as steel
Matter, then composite nano-powder and intermediate alloy are equipped with, it is made up of the method for powder metallurgy so that the strong steel alloy tool of heat obtained
There are good heat-resisting quantity, hardness, wear resistance and corrosion resistance, and service life is longer compared with ordinary steel.
