Description
Technical field
The present invention relates to the preparation method of a kind of rare earth catalytic cementation surface abrasion resistance Fe-W alloy, belong to steel alloy and Surface heat-treatent field.
Background technology
Ferrous materials is in composition designs, in order to reach higher wearability and hardness, it will usually add the elements such as C, W and Cr, reaches the purpose of strengthening by forming the means such as carbide, solution strengthening.
But, along with the raising of hardness, the machinability of material is also deteriorated.In some application scenario, it is only necessary to the hardness on some surface of parts and wearability improve, meanwhile require that the entirety of parts keeps preferable plasticity and toughness.
For meeting above demand, it is necessary to a kind of alloy of exploitation, plasticity and toughness and the machinability of material entirety can be kept, can have again preferable wearability and hardness.
The iron-based bianry alloy containing W is cheap, and plasticity and toughness are good, can form Fe after carburizing on top layer3C and WC, makes the hardness on surface and wearability be greatly increased, but after carburizing, the carburized layer hardness gradient on its top layer is relatively big, and carburizing is the longest.
Summary of the invention
The technical issues that need to address of the present invention are that the defect overcoming prior art, the preparation method of a kind of rare earth catalytic cementation surface abrasion resistance Fe-W alloy is provided, the alloy that it is prepared can keep overall plasticity and toughness and machinability, can have again preferable wearability and hardness.
For solving the problems referred to above, the present invention adopts the following technical scheme that
The invention provides the preparation method of a kind of rare earth catalytic cementation surface abrasion resistance Fe-W alloy, including pack carburizing step, being placed in the carburizer containing rare earth by Fe-W bianry alloy, within 4～9 hours, carry out Carburization Treatment 890～930 DEG C of insulations, carburizing is taken out carburizing part after terminating and is carried out Quenching Treatment.
In the present invention, the mass percent of Fe-W alloy composition is: W4.3～6.0%, and surplus is Fe.
The present invention, is polished bright with 240#, 800# and 1200# waterproof abrasive paper before embedment carburizer, and dries up with after ultrasonic cleaning in distilled water in surface by Fe-W alloy successively.
In the present invention, the proportion by weight of carburizer composition is: Linesless charcoal 55～75 parts, carborundum 5～10 parts, rare earth oxide CeO2Or La2O3
3～11 parts, and brium carbonate 8～12 parts.
In the present invention, before carburizing, carburizer is preheated to 850 DEG C, then after the seal case installing carburizer and Fe-W alloy is put into carburizer 5 minutes, after furnace temperature is risen to 890～930 DEG C, is incubated 4～9 hours.
In the present invention, quenching used medium is water.
Rare earth element has special chemism, after adding rare earth element, can add the decomposition rate of fast component and purify metal surface in carburizer, seepage velocity can be significantly improved, the wearability of infiltration layer can be improved simultaneously, improve the tissue of infiltration layer, reduce its fragility.
Thus, the beneficial effects of the present invention is: Fe-W alloying component used is simple, the addition of rare earth element, effectively shorten carburizing time, and carburized (case) depth can be increased, reduce carburized layer hardness gradient, and make microstructure refine, carbide dispersion degree increases, and has preferable toughness while keeping high rigidity.
Accompanying drawing explanation
Fig. 1 is that Fe-5.5W alloy is in 910 DEG C of carburizings longitudinal cross-section metallographic structure of 4 hours.
Fig. 2 is that Fe-5.5W alloy is in 910 DEG C of carburizings longitudinal cross-section microhardness change of 4 hours.
Detailed description of the invention
Embodiment
1
Fe-W alloying component mass percent is: W5.5%, Fe94.5%.Carburizer Ingredient percent is: Linesless charcoal 75%, carborundum 10, CeO25%, brium carbonate 10%.Fe-W alloy sample wire cutting machine is made 20 × 20 × 50mm sample, successively with 240#, 800# and 1200# liquid honing light, dries up with after ultrasonic cleaning in distilled water.The thick carburizer of 20mm is spread bottom corundum crucible, put into the sample made, and make sample distance corundum crucible wall more than 20mm, fill up in crucible remaining space with carburizer afterwards and be compacted, with high-temperature seal adhesive after crucible cover and crucible being covered, ensure that crucible inner space is full of the carburizer of compacting in the process.It is incubated after high temperature furnace temperature is heated to 850 DEG C, puts into the crucible of good seal, after 5 minutes, be warming up to 910 DEG C, take out crucible after being incubated 4 hours, sample is put into quenching-in water.
Fig. 1 is that Fe-5.5W alloy is in 910 DEG C of carburizings longitudinal cross-section metallographic structure of 4 hours.Fig. 2 is that Fe-5.5W alloy is in 910 DEG C of carburizings longitudinal cross-section microhardness change of 4 hours.
It is last that it is noted that obviously above-described embodiment is only for clearly demonstrating example of the present invention, and not restriction to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here without also cannot all of embodiment be given exhaustive.And the obvious change thus amplified out or variation still in protection scope of the present invention among.
