Abstract
The present invention discloses a micro-arc oxidization grinding and polishing method of a stainless steel surface, which comprises the following steps: the surface of a stainless steel product is mechanically polished, and oil is removed; the stainless steel product after oil removal is cleaned; the stainless steel product is put into dielectric solution, a sine-wave reverse power supply is switched on, a reaction on an anode is strengthened and activated by sine-wave micro arcs generated by the sine-wave reverse power supply at the temperature of 20 to 35 DEG C, and then a strengthened oxidizing film is formed on the surface of the stainless steel product; the stainless steel product generating the strengthened oxidizing film is cleaned and dried. The present invention solves the original problem of disability of oxidizing by the micro arcs on the stainless steel surface (an austenite and a martensite) and considerably enhances the protective performance and the application field of stainless steel.
Description
Technical field
The present invention relates to a kind of method for treating stainless steel surfaces, particularly a kind of method that forms one deck reinforcement oxide film at stainless steel surface.
Background technology
The common stainless steel material has good anti-corrosion " stainless " performance in water, steam, air, but in many corrosive mediums as Cl
-, SO
4 2-Form easily pitting, spot corrosion, crevice corrosion etc. in the medium, thus common stainless steel can not adapt to increasing as fields such as chemical industry, food, bio-pharmaceuticals to its performance demands.The high stainless steel of nickel content has the good oxidization resistance energy though it is now know that, thereby can reach " stainless " purpose of expection, thereby can expand the Application Areas of common stainless steel material, but because the natural resources shortage of starting material nickel, thereby cause the high stainless material cost of nickel content higher.The common employing of people is carried out the method for oxide treatment to stainless steel surface, and improving the corrosion resistance nature of stainless material, but effect is all not satisfactory.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides the differential arc oxidization abrasive polishing method for stainless steel surface of a kind of surface hardness height, corrosion resistance and good.
The technical solution adopted for the present invention to solve the technical problems is:
Differential arc oxidization abrasive polishing method for stainless steel surface is characterized in that this treatment process comprises the steps:
(1), at first surface of stainless steel product is carried out mechanical polishing, carry out oil removal treatment then;
(2), the Stainless Steel Products after the oil removal treatment is cleaned;
(3), Stainless Steel Products is placed the electrolyte solution that contains sodium polyphosphate 2～30%, Sodium Silicofluoride 5～10%, potassium fluotitanate 0.5～5%, Sulphanilic Acid 0.1～1%, polyvalent alcohol tensio-active agent 0.1～0.5%, connect sinusoidal wave commutation power supply, under 20～35 ℃ temperature condition, utilize the sinusoidal wave commutation sinusoidal wave differential of the arc that power supply produced, strengthen and the reaction of activation on anode, strengthen oxide film thereby form one deck at surface of stainless steel product;
(4), will generate then that the Stainless Steel Products of strengthening oxide film cleans, dry getting final product.
The sine wave commutation power supply that the present invention adopts is exactly on the basis of high-power (IGBT) switch power supply, after the modulation of pulse square wave process pilot circuit, curtage changes by sinusoidal rule, and electric current flows to anode from negative electrode, and the mobile ratio is reversible and changes.The operating voltage of sinusoidal wave commutation power supply is 20～300V.
Polyvalent alcohol tensio-active agent of the present invention is polyvinyl alcohol preferably.
The invention has the beneficial effects as follows: the present invention is by the sine wave commutation sinusoidal wave differential of the arc that power supply produced, utilize arc discharge to strengthen and activate and on anode, react, thereby be similar to the metal oxide film of pottery at the surface of stainless steel product formation one deck hardness, resistance toheat, the corrosion resistance that with nickel, titanium, chromium metal and alloy thereof are material, solve the difficult problem that in the past can not carry out differential arc oxidation at stainless steel surface (austenite and martensite), improved stainless barrier propterty and Application Areas greatly.Experiment showed, that the surface of stainless steel product microhardness that adopts after the present invention handles at 300～1000HV, reaches as high as 3000HV, can compare favourably with Wimet; Process stabilizing of the present invention is reliable, and the equipment of employing is simple, and reaction is carried out at normal temperatures, and is easy to operate, is easy to grasp; Electrolyte solution belongs to environmentally friendly machine, meets the environment protection emission requirement.
The present invention is further described below in conjunction with embodiment.
