With the continuous progress of production technology, the corrosion resistance and other properties of the coating are further improved, and the zinc plating of steel is further researched, and the coated steel plate is developed from an early pure zinc coating to a contemporary zinc alloy coating, such as a zinc-aluminum alloy coating and an aluminum-zinc-silicon alloy coating. However, in a poor environment, the corrosion resistance of the zinc-aluminum alloy plated steel strip cannot meet the use requirement; an Al-Zn-Si alloy plated steel plate is a plated product with atmospheric corrosion resistance close to that of an aluminum plated layer, which is developed by Berlesh iron and steel company in the 70 th 20 th century, and the alloy components of the plated steel plate are 55% of Al, 43.4% of Zn and 1.6% of Si. The alloy coating has good corrosion resistance, and the corrosion resistance is 2-6 times higher than that of a pure zinc coating in an atmospheric corrosion environment, and the alloy coating is matched with an aluminum coating. However, the existence of the acicular silicon-rich phase of the plating layer and the plating layer mainly comprises coarse dendritic grains, thus the weldability and the formability are poor.
Prior artfor example, application publication No. CN 111850445 a discloses a method for producing a high corrosion-resistant hot-dip galvanized aluminum alloy coated steel sheet/strip, which comprises simultaneously performing degreasing cleaning, continuous annealing and comprehensive control of hot-dip plating processes on a raw material substrate. Wherein, the degreasing and cleaning process comprises the following steps: the temperature of the bath solution is controlled to be 60-80 ℃, the alkali liquor free alkalinity of the degreasing bath is 30-50 Pt, the free alkalinity of the cleaning bath is lower than 8Pt, and the drying temperature of the strip steel is 90-110 ℃; the continuous annealing process comprises the following steps: hydrogen in the furnace is more than or equal to 3.0 percent, and the temperature of the hydrogen in the furnace in a zinc pot is 450-520 ℃; the hot dip plating process comprises the following steps: the zinc pot comprises, by mass, 8-12% of Al, 0.1-0.6% of Si, 0.05-0.3% of Re, and the balance of zinc and inevitable impurities; the temperature of the zinc pot is 470-500 ℃, and the obtained steel plate/strip of the alloy coating has excellent corrosion resistance and formability and good surface quality.
Disclosure of Invention
The invention aims to solve the technical problem of overcoming the defect of poor corrosion resistance of a steel plate strip plated with a zinc-aluminum alloy in the prior art, and provides a zinc-aluminum-magnesium-strontium-titanium alloy plating layer and a plating method for the steel plate strip, so that the corrosion resistance of the surface of the steel plate strip is greatly improved, and the machining performance of the steel plate strip is also improved.
The invention aims to provide a magnesium-strontium-titanium-containing zinc alloy coating with excellent corrosion resistance, wear resistance and self-repairing performance.
The technical scheme adopted by the invention for realizing the purpose is as follows:
a zinc alloy coating containing magnesium, strontium and titanium comprises zinc, aluminum, magnesium, titanium and strontium, and comprises the following components in percentage by weight: 0.15 to 3.5 percent of aluminum; 0.5 to 2.5 percent of magnesium; 0.01 to 0.05 percent of strontium; 0.002% -0.008% of titanium; the balance of zinc and inevitable trace impurities.
The addition of the magnesium element reduces the friction coefficient of the plated steel plate strip during subsequent processing, the number of electrons on the outermost layer of the magnesium, strontium and titanium elements added into the zinc alloy is respectively 2, 2 and 4, the electrons are in an unsaturated unstable state, and the electrons on the outermost layer are easy to lose and oxidize, so that a compact oxide film is formed on the surface of a plating layer, and the metal is prevented from being further oxidized; in addition, the addition of magnesium not only refines crystal grains, increases the wettability of the strip steel plate and strip with zinc liquid, but also can inhibit Mg2Zn11The structure inhibits intergranular corrosion and improves the corrosion resistance; meanwhile, the wear resistance of the zinc alloy coating is improved; in addition, the zinc alloy coating containing magnesium, strontium and titanium also has the alloy coating self-repairing function which is not possessed by the common hot-dip galvanized aluminum alloy coating, and after the steel plate strip is cut, the alloy coating can automatically wrap the steel base with the exposed cut end face in the daily environment, so that the self-repairing of the alloy coating on the surface of the steel plate strip is realized. The product of the invention is produced, which not only greatly improves the corrosion resistance of the traditional galvanized product, but also reduces the friction coefficient in the subsequent processing process and reduces the processing loss and energy consumption; the application range of the product is widened, and the product can be widely applied to high-end building materials, household appliances, underground pipe networks, photovoltaic energy, 5G industries and the like.
Preferably, the zinc alloy coating comprises xSr-yTi; wherein: x is more than or equal to 1 and less than or equal to 5, and y is more than or equal to 0.02 and less than or equal to 0.8.
According to the invention, xSr-yTi is formed by metal Sr and Ti, and the metal Sr and Ti are added into a zinc alloy coating to form a zinc-aluminum-magnesium-strontium-titanium quinary alloy coating; xSr-yTi improves the corrosion resistance, wear resistance and self-repairing performance of the zinc alloy coating; the reason may be that xSr-yTi in the preparation process, certain solid solution or change occurs between the crystal structures of the metal strontium and the metal titanium to form a new crystal structure, and the new crystal structure can act synergistically with other components in the zinc alloy, so that the corrosion resistance and the wear resistance of the zinc alloy coating containing magnesium, strontium and titanium are improved, and the zinc alloy coating containing magnesium, strontium and titanium has good self-repairing performance, and is different from the common hot-dip galvanized aluminum alloy coating.
The invention also discloses application of xSr-yTi in improving the corrosion resistance of the zinc alloy.
The invention also discloses application of the zinc alloy coating containing magnesium, strontium and titanium in steel plate belts, high-end building materials and/or underground pipe networks.
