Description
Technical field
The invention belongs to the metallic substance process field, particularly improve the treatment process of ferromagnetic metal material wear resisting property.
Background technology
The wear resistance that how to improve metallic substance is the important research direction in material engineering field always, and at present the approach that adopts comprises two kinds of coversion material prescription and processing modes.
In processing mode, thermal treatment can effectively improve the wear resistance of metallic substance and be used widely.But because unrelieved stress and incomplete transformation that heat treatment process produces are difficult to the wear resistance of metallic substance is brought into play to greatest extent; In addition, the scaling loss of distortion, oxidation and part element that heat treatment process is introduced makes thermal treatment not limit use range as final operation.
Summary of the invention
For overcoming the defectives such as scaling loss of distortion, oxidation and part element that the unrelieved stress that produces in the existing heat treatment technics and incomplete transformation and heat treatment process introduce.The present invention proposes a kind of new metallic substance treatment process, and this method reduces unrelieved stress on the basis of metal heat treatmet, reduce the degree of incomplete transformation, and do not have distortion, make the part wear resistance be greatly improved, have wide Application Areas.
The present invention realizes with following technical scheme:
The feature of this technology is that the processed part made from metallic substance is fixed on the jig, and the jig that fixes part is put into a radio-frequency induction coil, and the radio-frequency induction coil that part and jig will be housed again is placed in the low frequency excitation coil.
During work, because the induced current of workpiece inside can make workpiece be subjected to the effect of lorentz's force under the action of a magnetic field, under certain induction frequencies and induction condition, lorentz's force makes workpiece be in vibration condition, produces mechanical energy.Like this, receive the energy of three parts in the processed workpiece simultaneously: first part is the magnetic energy from the low frequency excitation coil, the vibration mechanical energy that the induction electric energy that second section produces in workpiece from radio-frequency induction coil, third part come self-induction current and magnetic field coupling to produce.
Concrete technical scheme is as follows:
In the operation, can be according to the different choice of the difference of science and engineering part of living in and the material model suitable radio-frequency coil and the operating parameters of low frequency excitation coil.Parameter is chosen as preferably:
First part produces the equipment and the parameter of magnetic energy: field power supply is produced by Beijing Wei Dun company, model is RJ-50, the low frequency excitation coil turn is the 100-500 circle, and field power supply is directly coupled together with lead and low frequency excitation coil, can produce required magnetic field.The parameter area of actual treatment is: alternating-current peak point current 30-80 ampere, frequency 10-50Hz.
Second section produces the equipment and the parameter of induction electric energy: induction power supply is produced by Shanghai Teng Chang company, and model is GP26, and radio-frequency induction coil is the 3-10 circle, and the output terminal of induction power supply is connected on the radio-frequency induction coil, can produce required induced current.The parameter area of actual treatment is: frequency 5-80kHz, output rating 1-7kW.
After being fixed on workpiece on the jig, open low frequency excitation power supply and high frequency induction power supply simultaneously, after work for some time, promptly finish processing workpiece.The general treatment time is more than the 30s, preferred 30s～500s.
Under the acting in conjunction of magnetic field and electric current, ferromagnetic metal inside can produce mangneto plasticity and Electroplastic simultaneously, reduced the potential barrier that high-energy state moves to low-energy state in the material, the effect that produces be beneficial to that unrelieved stress reduces and unstable phase to the transformation of stable phase, the mechanical energy that induced current and magnetic field coupling simultaneously produces has promoted the degree and the efficient of this moving process, the amplitude that unrelieved stress is reduced is bigger, and the transformation of unstable phase is also more thorough.These two processes have remedied the deficiency in the heat treatment process, have significantly improved the wear resistance of metallic substance, particularly significantly improve the wear resistance of ferromagnetic metal material, and significantly improve the work-ing life of workpiece.Metallic substance treatment process of the present invention can be widely used in the metallic substance in fields such as electron trade, mechanical processing industry, mining industry, construction industry, automobile industry and handle.
