The passivation method sequentially comprises the following steps of oil removing and degreasing treatment, ultrasonic wave rinsing treatment, passivation treatment, cleaning treatment, sealing treatment and drying treatment. The metal surface treated through the passivation method is good in corrosion resistance, and the method is easy to operate and reliable. The passivated metal surface is high in strength.
Description
Technical field
The present invention relates to a kind of metal processing sectors, particularly relate to a kind of Passivation Treatment of metallic surface.
Background technology
Passivation, be a kind of active metal or alloy, wherein chemically reactive reduces greatly, and becomes the phenomenon of precious metal state.If metal has fine and close structure due to the corrosion product that the effect of medium generates, define thin film (invisible often), closely cover metallic surface, then change metallic surface state, make the electropotential of metal greatly to positive dirction transition, and become anti-corrosion passive state.If standard potential during Fe → Fe++ is-0.44V, jump to+0.5 ~ 1V after passivation, and demonstrate corrosion resistant precious metal performance, this layer film is just passive film.But the current inadequate science of metal passivation method, affects the follow-up deep processing of product, the acid solution also having current Passivation Treatment to use also can produce detrimentally affect to environment.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of metal surface passivation method solved the problem.
The solution that the present invention solves its technical problem is: a kind of passivating method of metallic surface, comprises the following steps successively: oil removing skimming treatment, ultrasonic rinsing process, Passivation Treatment, clean, sealing treatment, drying treatment; What described oil removing degreasing adopted is emulsion degreasion method; The passivating solution used in described Passivation Treatment comprises: gamma-methyl allyl acyloxypropyl trimethoxysilane 20-25%, KH-560 silane 15-18%, organic inhibitor 1-2%, nanosized silica particles 0.1-0.3%, methyl alcohol 3-8%, acetic acid 5-7%, water 40-60%; The encapsulant that described sealing treatment uses comprises: 20-40%Al, 50-70%FeAl, 5-8% rare earth oxide and 0.4-2%NH
4cl; Described drying treatment is placed in drying oven by hardware, controls the temperature of drying oven at 80-100 DEG C of inner drying 1.3-2.0h.
As the further improvement of technique scheme, described clean carries out soaking and washing with pure water, and soaking temperature is 25-35 DEG C, and soak time is 20-50min.
The invention has the beneficial effects as follows: the metal surface anticorrosive performance after this passivating method is good, and present method is simple to operate, reliable, the metallic surface intensity after passivation is high.
