Abstract
The invention discloses an electrolytic manganese laser passivation method. The method includes the following steps that (1) light beams emitted by a laser scan the outer surface of a metal manganese layer which is attached to a stainless steel sheet; (2) after the outer surface of the metal manganese layer on the stainless steel sheet is scanned by the light beams emitted by the laser, micro-structuralization is formed in the structure. By means of the electrolytic manganese laser passivation method, pollution to the environment can be avoided.
Description
Technical field
The present invention relates to a kind of electrolytic manganese laser passivating method adopted in electrolytic metal Mn production process.
Background technology
Prior art, in electrolytic metal Mn production process, usually adopts stainless steel thin slice as negative electrode, layer of metal manganese will be adhered in the surface of such stainless steel thin slice.In above-mentioned electrolytic metal Mn production process; comprise and Passivation Treatment is carried out to the surface of the layer of metal manganese that stainless steel thin slice adheres to; the manganese metallic surface of loosening can be made to form the fine and close protective membrane of one deck by this Passivation Treatment, thus ensure that manganese metal can not be oxidized in transportation.The method of the existing manganese metal passivation to stainless steel thin slice adheres to, what usually adopt is chemical passivation method; First the stainless steel thin slice being attached with layer of metal manganese is put into the solution of potassium bichromate; the manganese metal surface of loosening is made to form the fine and close protective membrane of one deck; then the stainless steel thin slice being attached with layer of metal manganese is taken out, make the stainless steel thin slice being attached with layer of metal manganese enter subsequent processing.Because above-mentioned traditional passivating method have employed poisonous potassium bichromate, therefore not only contaminate environment, and the safety of harmful to human.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of electrolytic manganese laser passivating method, and this electrolytic manganese laser passivating method can avoid the pollution to environment.
In order to solve the problems of the technologies described above, a kind of electrolytic manganese laser of the present invention passivating method, comprises the following steps:
(1) beam flying adopting laser apparatus to launch is attached to the outside surface of the manganese metal layer on stainless steel thin slice;
(2), after the beam flying that the manganese metal layer outside surface on stainless steel thin slice is launched at laser apparatus, structurally micro-structural is formed.
In above-mentioned electrolytic manganese laser passivating method, by the outside surface adopting the scanning of laser apparatus transmitted beam to be attached to the manganese metal layer on stainless steel thin slice, the structure of the manganese metal layer outside surface be attached on stainless steel thin slice is made to form micro-structural, due to the micro-structural that manganese metal layer outer surface structure is formed, substantially increase surperficial erosion-resisting ability, therefore ensure that manganese metal can not be oxidized in transportation.Adopt poisonous potassium bichromate because above-mentioned passivating method compared with prior art avoids, therefore avoid environmental pollution, it also avoid the harm to human-body safety simultaneously.
Embodiment
A kind of electrolytic manganese laser passivating method, comprises the following steps:
(1) beam flying adopting laser apparatus to launch is attached to the outside surface of the manganese metal layer on stainless steel thin slice;
(2), after the beam flying that the manganese metal layer outside surface on stainless steel thin slice is launched at laser apparatus, structurally micro-structural is formed.
In above-mentioned electrolytic manganese laser passivating method, by the outside surface adopting the scanning of laser apparatus transmitted beam to be attached to the manganese metal layer on stainless steel thin slice, the structure of the manganese metal layer outside surface be attached on stainless steel thin slice is made to form micro-structural, due to the micro-structural that manganese metal layer outer surface structure is formed, substantially increase surperficial erosion-resisting ability, therefore ensure that manganese metal can not be oxidized in transportation.Laser provides a kind of method that energy with light carrys out passivation electrolytic manganese outside surface, the light beam that laser apparatus is launched is moving in the process of sweeping, processed electrolytic manganese outside surface impact by the laser pulse up to 50000 times per second, but because the form of impacting is a kind of laser of pulsed, the time that each pulse in fact rests on processed electrolytic manganese outside surface is very short, thus make laser not have time enough and processed electrolytic manganese produces Heat Conduction Phenomenon, therefore can not be damaged to the outside surface of processed electrolytic manganese.When laser energy density reaches some degree, processed electrolytic manganese outside surface (generally within 5 μm) structurally will make to loosen and becomes fine and close or claim micro-structural, the namely change of this electrolytic manganese outside surface, makes electrolytic manganese outside surface have powerful erosion-resisting ability.Adopt poisonous potassium bichromate because above-mentioned passivating method compared with prior art avoids, therefore avoid environmental pollution, it also avoid the harm to human-body safety simultaneously.Above-mentioned electrolytic manganese laser passivating method, the electrolytic solution that the manganese metal layer outside surface on stainless steel thin slice can be made to carry and pollutent gasify and collect, and do not affect environment, do not produce pollutent.Above-mentioned electrolytic manganese laser passivating method, flexible, use wide, can fully automated be realized.
Claims (1)
