Description
Technical field
The present invention relates to technical field of alloy, specifically, being related to a kind of kirsite.
Background technology
Galvanizing is that the metals such as steel, stainless steel, cast iron are immersed in fused solution metal or alloy to the one kind for obtaining coating
Technology.Galvanizing is most widely used, steel surface processing method that the ratio of performance to price is optimal in the world today.Galvanizing
Product lengthens the life to the corrosion inhibitor of steel, energy-saving material-saving plays inestimable and irreplaceable role, while electroplated steel products are also state
The high added value undersupplied product that family fosters and first develops.Hot galvanized layer forming process be iron-based body with outmost pure zinc layer it
Between form the process of iron-kirsite, workpiece surface forms iron-zinc alloy layer in hot-dip, just makes between iron and pure zinc layer
It combines very well.
When zinc layers are destroyed seriously, when injuring iron-based body, zinc generates electrochemical protection, the normal potential-of zinc to matrix
0.76V, the normal potential -0.44V of iron, zinc is dissolved as anode when zinc forms micro cell with iron, and iron is protected as cathode
Shield.Obvious galvanizing is better than electrogalvanizing to the weather-resistance of parent metal iron.Since the standard electrode potential of zinc is defeated by
Iron, therefore zinc coat has the function of anode loss protection base steel in water and wet air, so as to greatly extend
The service life of steel.Industrially common zinc coat has galvanizing by dipping, electrogalvanizing, mechanical zinc-plating and thermal spraying（Plating）Zinc
Deng, wherein galvanizing accounts for about the 95% of zinc-plated total amount, and galvanizing worldwide accounts for the 40% of zinc yield with zinc amount, China about
Account for 30% or so of zinc yield.
The application of galvanizing also accordingly expands with the development of industrial or agricultural.Therefore, in industry, (such as chemical industry is set hot dip zinc products
Standby, PETROLEUM PROCESSING, seafari, metal structure, power Transmission, shipbuilding etc.), agricultural is (such as：Sprinkling irrigation, dim room), building (such as：Water
And coal gas conveying, cable conduct, scaffold, house etc.), bridge, transport etc., be used in large quantities.Due to galvanizing
Product has the characteristics that specious, corrosion resistance and good, will be used wider and wider general.
The quality of galvanizing is related with many factors, includes the chemical composition of steel part, the alloying component of zinc bath, zinc-plated temperature
Degree, operating procedure etc..For the chemical composition of steel part, influence of the silicon content to zinc coat in steel is maximum.In general, working as
When silicon content in steel is more than 0.3wt.%, zinc coat significantly thickens and surface is gloomy, and poor adhesion, zinc coating quality significantly drops
Low this kind of steel of is known as active steel the galvanizing industry more.Wherein, silicon content is known as low activity in the steel of 0.3-0.8wt.% and contains Si
Steel.When the content of silicon in steel is higher than 1.2wt.%, referred to as high silicon content active steel.The hot-dip coated surface of active steel is solidifying
When there is the crystallization decorative pattern of coated metal, this crystallization decorative pattern is particularly evident to galvanized sheet, shows beautiful zinc crystallization
Appearance, thus as the important feature of heat zinc coating plate appearance, commonly referred to as this crystallization decorative pattern is spent for zinc.This zinc-plated plate surface liquid
Zinc forms beautiful zinc flower after crystallisation by cooling, and as the distinctive mark of galvanized sheet, is widely used in building trade.But
It is that when hot-dip galvanizing sheet steel carries out application, surface relief injustice caused by zinc is spent is still high-visible after painting, to influence
The surface quality of product limits the application of normal zinc flower hot-galvanized steel plate.
In order to solve low silicon content（0.3-0.8wt.%）The zinc coating quality problem of active steel has developed a variety of zinc-plated skills
Art, such as sealer galvannealing, the zinc-plated side of high temperature etc..But supplement zinc-nickel in the regular bath toward zinc is needed to close using these methods
Gold, and cadmia in zinc bath can be made to increase, in addition the technology is only effective less than 0.25% active steel to silicon content.In recent years, Billy
When and the Galvanco alloys that propose of Canada Company can comprehensively solve activity galvanizing steel problem, and some are national in Europe
Application is arrived.But these methods for high silicon content active steel and are not suitable for.Although at present can be by living in high silicon content
Property steel surface form one layer of barrier layer and then carry out galvanizing to reduce or delay influence of the silicon to zinc coat in steel.But chemical plating
Nickel method need to carry out at relatively high temperatures, and plating solution maintenance is more difficult.In addition, cost is very high, and enable plating piece the deformation even tendency of cracking
Seriously.
