Abstract
A plasma method for preparing anticorrosion surface of metal material uses a treater composed of reaction chamber, rotary axle and drawing axle. Two cathodes are arranged at upper and lower positions of the reaction chamber. The metal material to be treated is arranged between them. After said reaction chamber is vacuumized while filled with the gas mixture of hexamethyl disiloxane and helium gas, a DC high voltage is applied to break through said gas mixture for generating plasma to attach a film on the surface of metal material.
Description
Technical field
The present invention relates to about by carry out method with plasma technology the corrosion-resistant treatments of metallic substance.
Background technology
Usually, air-conditioner outdoor unit is provided with heat exchanger in its inside.Its heat exchanger is to be made of parts such as the heating panel of the anchor of stainless steel and aluminium material and copper pipes.
Because air-conditioner outdoor unit is outdoor because of mainly being arranged on, so consider and blow when drenching with rain, off-premises station is under this environment, generally selects material erosion-resisting and that heat exchange performance is good.
But, though the heating panel of heat exchanger of air condition adopts erosion-resisting aluminium material usually, be arranged on as the South-West Asia, the high temperature of beach, South East Asia one band, humidity, under the salt geographic outdoor situations how, still there is easy corrosive problem in the heating panel of off-premises station.
In order to overcome the above problems,, on the heating panel of air-conditioner outdoor unit, carry out the chromium plating spraying, to reach the purpose of corrosion-resistance treatment in the abominable area of weather condition.This situation though can increase the service life on some degree, improves to some extent, and erosion resistance does not still reach the satisfied degree of user, and the damage problem that takes place to cause because of corrosion also happens occasionally.
Summary of the invention
In order to address the above problem, the invention provides a kind of anti-rotten treatment process of metal of utilizing plasma technique.Its way is in the provocative reaction chamber interior, by suitable proportion supply response gas, applies volts DS simultaneously.Therefore, adding on the labor and materials surface, adsorbing the very strong polymer thin film of erosion resistance.
Technical scheme of the present invention has provided a kind of method for anticorrosion treatment of metal that utilizes plasma technique, it is characterized in that comprising the treatment unit of a provocative reaction chamber 101, winding axle 105 and axis of traction 107 compositions, at the upper and lower position of provocative reaction chamber 101 negative electrode 102,103 is set respectively, in the middle of described two negative electrodes, is provided with processed metallic substance 104 and is anode; In the provocative reaction chamber 101 li is that 1500ml/min: 2100ml/min injects hexamethyldisiloxane ((CH by throughput ratio

3) 3) and the mixed gas of helium, provocative reaction chamber 101 pressure inside effectively control to set vacuum state by vacuum pump 113; Described treatment unit is connected power supply 114, the high voltage direct current of input 1100V-1300V, and described mixed gas is breakdown, produces plasma body and obtains the surface that polymer thin film is adsorbed on processed metallic substance 104, forms etch resistant layer.
Implement treated metallic substance, the sampling resistance height of the resistance value ratio chromium plating material of its mensuration by method of the present invention.This illustrates that treated metallic substance resistance is high more, and erosion resistance is good more.So the erosion resistance of the material of handling with method for anti-corrosion treatment of the present invention is greatly improved.
Description of drawings
Fig. 1 is the simplified diagram of corrosion-resistant treatments device of the present invention.
Fig. 2 is the surperficial resistance value ratio graphic representation that adds labor and materials sample and original spray process material sample of corrosion-resistant treatments of the present invention.
The explanation of the symbol of drawing major portion:
101: provocative reaction chamber 102: upper electrode
103: lower electrode 104: work material
Embodiment
With reference to accompanying drawing, illustrate that technical scheme of the present invention is to realize like this, in order to achieve the above object, on idle call metal work material surface, form the erosion resistance plated film, its process is as follows: in the provocative reaction chamber interior, negative electrode and anode are set, internal pressure in the described reaction chamber effectively controls to set vacuum state by vacuum pump 113.Ratio in 1500ml/min: 2100ml/min, in above-mentioned reaction chamber, inject the mixed gas of hexamethyldisiloxane and helium, and in the 1100V-1300V interval, input direct voltage between above-mentioned anode and negative electrode, mixed gas is breakdown, produce plasma body and obtain the surface that polymer thin film is adsorbed on processed metallic substance 104, form etch resistant layer.
As shown in Figure 1, inboard in box-like provocative reaction chamber 101, top is upper electrode 102 fixedly, at the downside of upper electrode 102, fixedly lower electrode 103, the side in provocative reaction chamber 101, the reaction chamber 106 that twines axle 105 is equipped with in setting, the reaction chamber 108 of axis of traction 107 is equipped with in the opposite side setting, by twining axle 105 twining sheet aluminium sheet processing material 104, continuously supplies with the provocative reaction chamber interior.Axis of traction 107 be constantly twine from the provocative reaction chamber, to come out add labor and materials 104.In that export department of twining axle 105 reaction chambers 106 and the inlet portion that axis of traction 107 reaction chambers 108 are housed are housed, a pair of guide deflection sheave 109 is being set respectively.Its effect is that the guiding of secondary process material moves.
A side below above-mentioned provocative reaction chamber 101 is being provided with gas injection tube 111, and it acts on for injecting gas.Opposite side in provocative reaction chamber 101 is provided with in order to discharge the waste gas exhaust pipe 112 after reaction finishes, and on its vapor pipe 112 vacuum pump 113 is set, and the effect of this pump is in order to make the provocative reaction chamber interior can keep the vacuum state of setting.
On above-mentioned provocative reaction chamber 101, DC power supply switch 114 is being set, its effect is for lower electrode 102,103 upwards and adds labor and materials 104 (anode) and supply with direct supply.Do not show the motor that should possess on the drawing.It is to twine axle 105 and axis of traction 107 in order to rotate.
The coating film treatment device of Gou Chenging thus, the method that its metallic surface forms the erosion resistance plated film is as follows:
The input power supply makes electric motor driving, twines axle 105 immediately by running counterclockwise, and axis of traction 107 is also by running counterclockwise; Be wrapped in the flaky aluminum that twines axle 105 and add upper electrode 102 and the lower electrode 103 of labor and materials 104, be wrapped in uninterruptedly on the axis of traction 107 by being arranged on the provocative reaction chamber interior.In this state, by gas inlet 111, mixed gas is injected into the inside of provocative reaction chamber 101, this mixed gas is hexamethyldisiloxane ((CH
3) 3SiOSi (CH
3) 3) and helium press 1500ml/min: the 2100ml/min mixed.Electrode 102,103 and add the voltage of input 1100V-1300V scope on the labor and materials 104 simultaneously, breakdown at top and the bottom electrode 102,103 and the mixed gas that adds between the labor and materials 104 so, produce plasma body and obtain the surface that polymer thin film is adsorbed on processed metallic substance 104, form etch resistant layer.
Fig. 2 is the result that the surperficial resistance recording method that adds labor and materials sample and original spray process material sample of corrosion-resistant treatments of the present invention is measured.X-axis is the sensitive range of the detected corrosion measurement EIS of respective frequencies value, and Y-axis is the electrode resistance, and what its resistance showed is the absolute value of impedance, finds out that from comparison curves resistance is high more, and erosion resistance is good more.
