The preparation method of particle enhanced steel iron-based composite breaking wall.
Background technology
Gyratory crusher suitable for it is metallurgical, build, build the road, raw material is broken chemistry and silicate industry, according to broken
The difference and product particle of principle is of different sizes, and many models are divided into again.Cone crushing is lower than big, efficiency high, energy consumption,
Product granularity is uniform, broken and in small, broken bits various ores in being adapted to, rock.When gyratory crusher works, motor is rotated through skin
Belt wheel or shaft coupling, drive shaft of cone crusher and gyratory crusher conus portion eccentric bushing it is forced to move under make around a fixing point
Swing campaign.So that the rolled mortar wall surface being packed in adjusting sleeve is left when close during the crushing wall of crushing head,
Ore is constantly impacted in crusher chamber, extruding and flecition and realize the broken of ore.Therefore, crushing wall is circular cone
The main stressed member of disintegrating machine, in order to improve the service life of disintegrating machine, just has to improve the abrasion resistance properties of crushing wall.
Ceramic particle reinforced metal base composites had both possessed the good plasticity of parent metal and impact flexibility, easy-formation etc.
Advantage, while the high intensity, high rigidity and high-wearing feature but also with ceramic particle.When composite is worn and torn by the external world, just
Work when matrix phase is identical with enhancing in composite bed during the beginning, with the prolongation of wearing- in period, matrix phase gradually grinds off, strengthen phase
Further protect the substrate is then individually protruded, the overall wear resistance of material is improve.
The enhancing particle for preparing ceramic particle reinforced metal base composites selects ZTA ceramic particles, ZTA ceramic particles tool
There are many advantages that other particles are incomparable：First, ZTA is moderate relative to other particles that strengthen, and cost performance is high；Its
Secondary, closer to the thermal coefficient of expansion of ferrous materials, ZTA ceramic particles are used as strengthen mutually can be with for the thermal coefficient of expansion of ZTA ceramics
The composite with good thermal matching is obtained with iron-based.In addition, ZTA complex phase ceramics can be by controlling Al2O3 and ZrO2
Composition ratio, change its mechanical property and thermodynamic property parameter, such that it is able to prepare composite with different matrix phases, greatly
The range of application of ZTA complex phase ceramics is extended greatly.
But, associativity is poor between ZTA particles and iron-based, by ZTA ceramics in composite prepared by casting infiltration
Grain is combined into mechanical bond with iron-based so that ZTA ceramic particles cannot play enhanced effect.
The content of the invention
That what is invented aims to overcome that above technical problem, proposes that a kind of chemical activation processes ZTA particle reinforced irons
The preparation method of base composite breaking wall.
To achieve these goals, the present invention is adopted the following technical scheme that：
It is a kind of based on chemical activation process ZTA particle enhanced steel iron-based composite breaking walls preparation method, including with

2) the ZTA particles of titanizing are inserted in chemical nickel-plating liquid, using magnetic stirrer, simultaneously heating and thermal insulation 2-6 is little
When, form nickel dam in titanium coating periphery；
3) the ZTA particles after plating are sintered, is warming up to 1200 DEG C with the programming rate of 10-15 DEG C/min from room temperature, so
Afterwards 1400 DEG C of sintering are warming up to the programming rate of 5-8 DEG C/min, along with the furnace cooling, it is prefabricated that ZTA particles are interconnected to hole shape
Body；
4) precast body is fixed on the end face or working face of casting mold, then using technology of infiltration casting cast steel substrate material gold
Category liquid, obtains ZTA particle enhanced steel iron-based composite breaking walls after cooling.
Further, step 1) in active element titanium be analytically pure titanium valve, titanium valve account for inorganic salts mass ratio be 10%-
15%.
Further, the mass fraction that ZTA particles account for titanium, inorganic salts and ZTA particle gross masses when salt bath is plated is 60%-
80%.
Further, nickel plating heating-up temperature is 70-90 DEG C.
Further, molten metal is potassium steel, chromium alloy cast iron or ni-hard cast iron.
Further, step 3) in 1400 DEG C sinter 1 hour.
Further, the inorganic salts are villaumite.
Further, the inorganic salts are sodium chloride, calcium chloride or potassium chloride.
Further, composite breaking wall is breaking wall of spindle breaker, gyratory crusher crushing wall, ring hammer crusher
Crushing wall or jaw crusher crushing wall.
Relative to prior art, the invention has the advantages that：The active element introduced in the present invention, salt bath titanizing
When titanium and ZTA ceramic grain surfaces form metallurgical binding, enhance the interfacial bonding property between titanium layer and ZTA ceramic particles, make
Combine between ZTA particles and metal and metallurgical binding is changed into from mechanical bond.ZTA ceramic particles after salt bath titanizing carry out again chemistry
Nickel plating, titanium nickel junction can generate Ti-Ni alloy, Nitinol layer serve between metallic matrix and ZTA particles one it is soft
The effect of property transition zone, greatly improves the bond strength at interface.
In the composite bed of the composite breaking wall that the present invention is prepared, metallic matrix is distributed in the hole of ZTA ceramic particles
In, when crushing wall is rubbed by foreign impacts, ZTA ceramic particles play certain protective effect to metallic matrix, so as to carry
The high abrasion resistance properties of crushing wall.
