Abstract
The utility model discloses a steel plate covered with a metal protecting layer, and relates to a steel plate with a surface covered with a metallic titanium protecting layer for preventing metal corrosion, acid rain, air etching, etc. The utility model comprises a steel plate basal body, a transition layer and a metal Ti layer. The transition layer selects any one of elements of Zn, Cr, Ni, Al, Si, or the transition layer is formed by Zn and any one of elements of Cr, Ni, Al, Si. the steel plate of the utility model has the advantages of good corrosion-resisting performance, high wear resistance performance, beautiful surface decoration, durable color, low cost, and convenient operation.
Description
A kind of steel plate that is covered with coat of metal relates to a kind of steel plate that is covering the protective layer of Titanium that preventing metal corrosion, acidproof rain and atmosphere etc. corrode etc. on the surface.
The anticorrosion anti-corrosion of steel plate is the problem that steel plate production and use must solve.At present, the extensive employing of people zinc-plated method on steel plate prevents the corrosion of steel matrix.But under environment such as acid rain, the corrosion resisting property of galvanized steel plain sheet is difficult to meet the demands.When using steel plate to make the cabinet of electronics, power equipment etc., behind steel plate bending, welding fabrication, ornamental for the corrosion resistance that guarantees its steel plate and cabinet must be through operations such as eliminating rust, spray paint, produce spent acid, waste gas to environment generation pollution, and operating condition is poor.When being used for field such as highway guard rail and car floor, need good antiseptic property on the one hand, on the one hand good wearability to be arranged, present existing steel plate and galvanized sheet etc. are difficult to satisfy above requirement.
The purpose of this utility model is exactly in order to overcome the shortcoming of above-mentioned prior art, and a kind of have corrosion resistance and good, new steel plate that anti-wear performance is good, the incrustation performance is good, be covered with coat of metal on the surface are provided.
The purpose of this utility model is achieved through the following technical solutions.
A kind of steel plate that is covered with coat of metal is characterized in that its structure comprises: steel matrix; The alloy formation that to be a kind of element optional among any element that is selected from Zn, Cr, Ni, Al, Si of combining closely with the steel matrix surface or Cr, Ni, Al, the Si form with Zn of transition zone, this transition zone; The metal Ti layer, combine closely in this metal Ti layer and described transition zone surface.
Steel plate of the present utility model has corrosion resistance and good, wearability height, incrustation lasting, cost advantage low, easy to use attractive in appearance.Product can be widely used in fields such as automobile, household electrical appliances, power equipment, construction ornament materials.Because the special performance that has of Titanium, make its than present widely used galvanized steel plain sheet corrosion resistance better.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is the structural representation of the steel plate of two-sided coating for the utility model.
The utility model is described in further detail below in conjunction with accompanying drawing.
A kind of steel plate that is covered with coat of metal is characterized in that its structural group becomes: steel matrix 1; The transition zone 2 of the alloy formation that optional a kind of element and Zn form among any element that is selected from Zn, Cr, Ni, Al, Si of combining closely with the steel matrix surface or Cr, Ni, Al, the Si; The metal Ti layer 3 of combining closely with described transition zone surface. The coat of metal that is covered with on the steel plate can overlay on the steel plate upper and lower surface simultaneously.
Coat of metal of the present utility model is the depositing operation preparation of adopting arc ion plating, its coating excellent bonding performance, and the titanium layer that is covered with on the steel plate has strengthened the anticorrosion and corrosion resisting property of steel plate greatly.
Embodiment
On the 2mm surface of steel plate, adopt the depositing operation of arc ion plating, be covered with Zn-Ni alloy transition zone, the 1 μ mTi titanium layer of 1 μ m.The NaCl aqueous solution of employing 5% is corrosive liquid, and corrosion resisting property was as the criterion with the time that the appearance of φ 1mm rust staining occurs, and its performance indications and correction data thereof are as follows:
| Test piece number (Test pc No.) | Coating | Corrosion resisting property |
| 1 | Zn layer 14 μ m | 24 |
| 2 | Zn-Ni layer μ m, Ti layer μ m | 146 hours |
Claims (1)
