Abstract
The invention discloses a kind of gasification film coating method of low melting point metal, realized by following step: the low melting point metal of coating is put into melting of metal pond and melted by (1), arranging melting of metal pond temperature is 250 ~ 850 DEG C, gasification to the boiling of coating low melting point metal; (2) plating metal is passed into the process furnace be communicated with described melting of metal pond, described coated metal gas enters the process furnace being full of protective gas and is independently attached to plating metal on the surface; (3) plated film complete after the coated metal of tool pass into and be full of protective gas refrigerating unit and cool.The present invention is the advantage combining hot dip and Vacuum Deposition, and coating is complete, thickness of coating adjustable, and coating is even, economizes on resources in a large number and environmental protection relative to electroplating technology.
Description
Technical field
The present invention relates to a kind of gasification electro-plating method of low melting point metal, belong to electroplating technology field.
Background technology
When low melting point metal is as coated metal, require that its coating is stable, even.According to this requirement, electro-plating method mainly hot dip and the Vacuum Deposition of prior art, hot-dipping method operationally, coated metal is molten state, and plating metal can not reach the temperature identical with coated metal, as zinc-plated on steel band, steel band just can not be made to reach the temperature of molten tin, so, when being entered the reaction tank of the coated metal of carrying melting by conveying roller at steel band, meet cold spray explode phenomenon with regard to having molten metal, and steel band slowly enters reaction tank with certain speed, so after having electroplated, uneven coating is even, surface irregularity, subsequent technique is tediously long, and very waste plated material.Another method is Vacuum Deposition, and Vacuum Deposition is mainly used in plated film, and as the precious metal material such as germanium, titanium just can use, low melting point metal adopts Vacuum Deposition cost higher, and rate of utilization is lower.
Summary of the invention
The invention provides a kind of gasification film coating method of low melting point metal, coating unfairness when solving the plating of current low melting point metal, the problem that uneven and cost is higher.
The present invention is realized by following technical scheme:
A gasification film coating method for low melting point metal, it is characterized in that by following step realize:
(1) low melting point metal of coating is put into melting of metal pond to melt, arranging melting of metal pond temperature is 250 ~ 850 DEG C, gasification to the boiling of coating low melting point metal;
(2) plating metal is passed into the process furnace be communicated with described melting of metal pond, described coated metal gas enters process furnace and is independently attached to plating metal on the surface;
(3) electroplated the coated metal of rear tool to pass into refrigerating unit and cool.
Low melting point metal in described step (1) comprises tin, aluminium.
Described step adds rare gas element or reducing gas in (1) in melting of metal pond and refrigerating unit.
Describedly go back rare gas element or reducing gas is hydrogen or helium.
Beneficial effect of the present invention is:
1. this electro-plating method does not relate to molten metal, can not produce metal and meet the fried phenomenon of cold spray, thus the problem that uneven coating can not be caused even.
2. the speed that this electro-plating method can run in process furnace according to plating metal adjusts the thickness of coating.
3. this electro-plating method is cost-saving, is applicable to large-scale promotion.
