Description
Technical Field
The present invention relates to a steel sheet and a method for manufacturing the same, and more particularly, to a vacuum-plated steel sheet and a method for manufacturing the same.
Background
The corrosion resistance of the steel plate can be improved and the service life of the steel plate can be prolonged by plating the corrosion-resistant coating on the surface of the steel plate. At present, the composition of the corrosion-resistant coating varies depending on the use of the coated steel sheet, for example: the coating can be zinc, zinc-aluminum-magnesium, aluminum-silicon, etc. And the corrosion resistant coating can be applied using different coating techniques, such as: hot dipping, electroplating, vacuum plating, and the like.
For mild steel, the electroplating process has the defects of difficult production of a thick coating, high energy consumption, wastewater discharge and the like, while the hot-dip process has the problems of difficult improvement of speed and poor platability of steel containing B, and for common high-strength steel (less than 780MPa), the electroplating process has the problems of high energy consumption, difficult improvement of coating thickness, wastewater discharge and the like; the hot-dip process has the problems of high alloy content, poor platability of steel containing B, limited speed and the like. For ultrahigh-strength steel (greater than or equal to 780MPa), the problems of serious hydrogen embrittlement, difficult improvement of coating thickness and the like exist in an electroplating process, and the problems of poor platability, very high alloy content, difficult improvement of strength grade, hydrogen embrittlement and the like exist in a hot-dip plating process. The vacuum plating corrosion-resistant plating layer can not only improve the plating speed, but also solve the problems of hydrogen embrittlement and platability, and has no environmental pollution. In addition, the vacuum plating process is adopted, so that the components and the structure of the plating layer can be more flexibly optimized.
However, the vacuum plating process has a problem that the adhesion strength of the plating layer is insufficient, and the plating layer is peeled off when the product is processed, which finally results in a decrease in the workability of the vacuum plated steel sheet. Although a great deal of research is carried out at home and abroad on the aspects of surface treatment, coating component improvement, heat treatment, coating equipment and the like, the requirements of industrial mass production cannot be met well.
Disclosure of Invention
An object of the present invention is to provide a vacuum-plated steel sheet having excellent adhesion strength, excellent coating adhesion, and good workability.
In order to achieve the above object, the present invention provides a vacuum-plated steel sheet having excellent adhesion strength, which includes a substrate and an anti-corrosion layer, and further includes a pre-plating layer formed on a surface of the substrate, the anti-corrosion layer being formed on a surface of the pre-plating layer; wherein the pre-plating layer comprises at least one of iron, chromium, nickel, titanium, zinc, aluminum and tin.
In the technical scheme of the invention, since the smaller the particles deposited on the surface of the substrate in vacuum, the more beneficial the low porosity of the corrosion-resistant layer is, the better the environmental protection and economic aspects are considered, the preplating layer with at least one of the elements of iron, chromium, nickel, titanium, zinc, aluminum and tin is preferably adopted, so that the vacuum-plated steel plate of the scheme has excellent adhesion strength.
Further, in the vacuum-plated steel sheet having excellent adhesion strength according to the present invention, the precoated layer is made of at least one of pure iron, pure chromium, pure nickel, pure titanium, pure zinc, pure aluminum, pure tin, and an alloy of iron, chromium, nickel, titanium, zinc, aluminum, and tin.
Further, in the vacuum-plated steel sheet having excellent adhesion strength according to the present invention, the corrosion-resistant layer includes at least one of zinc, magnesium, and aluminum elements.
Further, in the vacuum-plated steel sheet excellent in adhesion strength according to the present invention, the anti-corrosion layer is made of at least one of pure zinc, pure magnesium, pure aluminum, a zinc-magnesium alloy, a zinc-aluminum alloy, an aluminum-magnesium alloy, a zinc-aluminum-magnesium alloy, and an aluminum-silicon alloy.
Further, in the vacuum-plated steel sheet excellent in adhesion strength according to the present invention, the thickness of the precoated layer is 3 to 1200 nm; and/or the thickness of the anti-corrosion layer is 2-12 mu m.
Accordingly, another object of the present invention is to provide a method for manufacturing a vacuum-plated steel sheet having excellent adhesion strength, which can obtain a vacuum-plated steel sheet having excellent adhesion strength, can be widely used in continuous vacuum plating of strip steel, and has a wide application prospect.
In order to achieve the above object, the present invention provides a method for manufacturing the vacuum-plated steel sheet having excellent adhesion strength, comprising the steps of:
(1) pretreating a steel plate;
(2) at 1 × 10-4Depositing on the surface of the steel plate to form a precoating by adopting a PVD vacuum coating process under the vacuum degree of Pa-100 Pa;
(3) at 1 × 10-4And depositing an anti-corrosion layer on the surface of the pre-plating layer by adopting a PVD vacuum coating process under the vacuum degree of Pa-100 Pa.
Further, in the manufacturing method of the invention, in the step (1), the pre-treatment at least comprises the steps of cleaning the steel plate, and then preheating the steel plate in a vacuum chamber, wherein the preheating temperature is 150-300 ℃.
In the manufacturing method of the invention, the preheating temperature is considered to be too low, so that the plating layer forms a slender columnar structure, the porosity of the plating layer is high, and the corrosion resistance of the plating layer is reduced. However, if the temperature is too high, the particles are deposited on the surface, and the energy is difficult to be absorbed quickly, and the particles can be separated from the surface of the substrate again, so that the yield of the plating material is low, and the plating material is dispersed in the vacuum chamber, which affects the stable operation of the plating equipment. Based on this, the preheating temperature is controlled between 150 ℃ and 300 ℃ in the technical scheme of the invention.
Further, in the manufacturing method of the present invention, the pretreatment in the step (1) further comprises plasma cleaning the steel sheet in a vacuum chamber after preheating, wherein at least one of the following parameters is satisfied when the steel sheet is cleaned, and the degree of vacuum is 1 × 10-2Pa-10 Pa; the cleaning time is 5-15 min; the cleaning working gas is argon or nitrogen.
In the above embodiment, the plasma cleaning can remove gas adhering to the substrate surface and oxide on the steel sheet surface. In plasma cleaning, argon or nitrogen is required to be filled, and plasma is generated by ionizing argon or nitrogen to clean. If the vacuum degree is too low, the density of generated plasma is too low, and the cleaning effect is not good; if the vacuum degree is too high, more argon will need to be filledBased on the control of the parameters during cleaning, considering the cleaning effect and the economic cost, the vacuum degree is 1 × 10-2Pa-10 Pa; the cleaning time is 5-15 min; the cleaning working gas is argon or nitrogen.
Further, in the manufacturing method of the invention, the PVD vacuum coating process is one of multi-arc ion plating, magnetron sputtering plating, induction evaporation plating, resistance evaporation plating, induction evaporation spray deposition plating and resistance evaporation spray deposition plating; when multi-arc ion plating or magnetron sputtering plating is adopted, the distance between the target material and the steel plate is 50-100 mm; when the induction evaporation plating, the resistance evaporation plating, the induction evaporation jet deposition plating or the resistance evaporation jet deposition plating is adopted, the distance between the evaporation source and the steel plate is 10-100 mm; and/or when the induction evaporation spray deposition plating or the resistance evaporation spray deposition plating is adopted, the spraying speed is 200-500 m/min.
In the above scheme, the reason why the distance between the evaporation source and the steel plate is controlled to be 10-100mm is that through a great deal of experimental research, the inventor finds that the uniformity of the coating is affected when the distance is less than 10mm, and the compactness of the coating is affected when the distance is more than 100 mm. Based on this, in the technical scheme of the invention, the distance between the evaporation source and the steel plate is controlled to be 10-100 mm.
The vacuum plated steel sheet with excellent adhesion strength and the manufacturing method thereof have the following advantages and beneficial effects:
the vacuum plated steel sheet with excellent adhesion strength can greatly improve the plating adhesion strength of the vacuum plated steel sheet, thereby ensuring the excellent processing performance of the plated steel sheet and improving the plating speed. In addition, the vacuum plated steel plate solves the problems of hydrogen embrittlement and platability in the prior art, and is environment-friendly in the production process.
In addition, the manufacturing method of the invention has the advantages and beneficial effects, and has no requirement on the components of the steel plate, so the manufacturing method can be popularized and applied in the continuous vacuum plating of the strip steel, and has wide application prospect.
