Abstract
The method of raising abrasive resistance of metal material features that metal material is treated with coupled ultrasonic field and electromagnetic field for 35-500 s. The ultrasonic field has output power of 20-110 W and frequency of 10-30 KHz; the LF exciting coil of 100-500 turns has peak AC current of 30-80 A and frequency of 10-50 Hz; and the HF inducing coil of 3-10 has frequency of 10-100 KHz and output power of 1-8 KW. The method is used on the basis of heat treatment of metal, and can reduce residual stress, decrease incomplete phase change and raise the wear resistance of the treated part greatly.
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:
Processed part is fixed on the jig, one end of jig connects ultrasonic transducer, the jig and the ultrasonic transducer that fix part are put into a high-frequency electromagnetic induction coil, and the radio-frequency coil that part, jig and ultrasonic transducer will be housed again is placed in the low frequency excitation coil.
During work, receive the energy of three parts simultaneously in processed workpiece: first part is the magnetic energy from the low frequency excitation coil, the electric energy that second section induces in workpiece from radio-frequency induction coil, and third part is from the mechanical energy of ultrasonic transducer.
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 material model the operating parameters of suitable ultrasonic wave, radio-frequency coil and 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, and model is RJ-50, and the low frequency excitation coil turn is 100～500 circles, and field power supply is directly coupled together with lead and magnet coil, can produce required magnetic field.The parameter area of handling is: 30～80 amperes of alternating-current peak point currents, 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 ruhmkorff coil is 3～10 circles, and the output terminal of induction power supply is connected on the ruhmkorff coil, can produce required induced current.The parameter area of handling is: frequency 10～100KHz, output rating 1～8Kw.
Third part produces the equipment and the parameter of ultrasonic energy: the GC-5025 ultrasonic transducer that adopts Wuxi Hui Feng company to produce, and output rating 110w, ultrasonic-frequency power supply flies ripple ultrasonic-frequency power supply factory by the Zhangjiagang to be provided.Processing parameter is: output rating 20～110w, frequency 10～30KHz.By screw and epoxy resin glue the output end face of ultrasonic transducer is connected on the jig.
After being fixed on workpiece on the jig, open low frequency excitation power supply, high frequency induction power supply and ultrasonic-frequency power supply simultaneously, after work for some time, promptly finish processing workpiece.The general treatment time is more than the 35s, preferred 35s～500s, most preferably 100s～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 ultrasonic energy that applies has simultaneously 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.
