Description
Technical field
The present invention relates to field of metal surface treatment technology, more particularly to a kind of passivating method of steel surface.
Background technology
Passivation is to be converted into metal surface to be not easy oxidized state, and delays the method for corrosion of metal speed.And
Black, the oxide skin of yellow occurs in steel in process, therefore, need to be in order to improve the outward appearance of steel and corrosion resistance
Processing is first passivated to steel before processing.
At present, although the deactivating process for the treatment of on steel surface has many kinds, its corrosion resistance general, it is hard to
Meet market demands.
The content of the invention
The present invention provides a kind of passivating method of steel surface, and the passivating method can be solved at existing deactivating process for the treatment of
Obtained steel surface corrosion resistance is managed general, it is hard to the problem of meeting market demands.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is：
Pending steel is first heated to 50 DEG C~80 DEG C by it, is then fully immersed in again in 5 DEG C~10 DEG C of passivating solution, and
Processing is passivated under the Ultrasonic Conditions that ultrasonic power is 50W~100W, supersonic frequency is 50KHz~80KHz；Wherein,
The passivating solution is to be prepared from the following raw materials in parts by weight：4 parts~6 parts of linear alkyl benzene sulphonate, octyl phenol polyoxy

And 50 parts~75 parts of water.
Due to using above-mentioned technical proposal, the beneficial effect that the present invention obtains is：
The present invention is first passed through using the principle expanded with heat and contract with cold, and is first heated pending steel, is then soaked in cold passivation again
In liquid, so as to promote passivating solution sufficiently to infiltrate through the top layer of steel, corrosion resistance is improved；Meanwhile further according to passivating solution
The specific ultrasonic power of components utilising and frequency carry out ultrasonic Passivation Treatment, so as to which further passivating solution sufficiently permeates
Enter the top layer to steel, improve corrosion resistance；Meanwhile using linear alkyl benzene sulphonate, OPEO,
Caused high osmosis between ethylene glycol and boric acid, so as to which further passivating solution sufficiently infiltrates through the top layer of steel,
Improve corrosion resistance.
