Problems solved by technology

During the recrystallization annealing process, these alloy elements are easy to produce external oxidation in the annealing furnace, and the oxides are enriched on the surface of the steel strip, which makes the wettability of the steel plate in the zinc pot worse, causing problems such as missing plating or surface slag inclusion, that is, The traditional steel hot-dip galvanizing process is not suitable for high-strength steel galvanizing; if the electroplating process is used, there will be "three wastes" that pollute the environment, which is restricted by environmental protection regulations and greatly limited in application; so advanced high-strength steel galvanizing It is a major problem that plagues various iron and steel enterprises and scientific research institutions
In the existing experimental technology, the preparation of alloy coating usually requires the combination of PVD vacuum coating equipment and vacuum annealing furnace. After coating, the product is transferred to the annealing furnace for annealing. Coating and annealing are carried out separately. Integrated with annealing in the same unit to produce the process flow of alloyed coated steel plate, the production cycle is long and it is easy to oxidize before the alloy coating is formed

Description

technical field [0001] The invention relates to physical vapor deposition technology, in particular to a multifunctional experimental device and an experimental method for preparing (Physical Vapor Deposition, PVD) zinc alloy coatings by using physical vapor deposition technology. Background technique [0002] As the most important corrosion protection product in the automotive, construction and home appliance industries, galvanized steel sheets provide corrosion protection for steel sheets. Galvanized steel sheets are affected by the lightweight of automobiles, the large-scale application of high-strength steel / advanced high-strength steel, and the shortage of zinc resources. Under the premise of ensuring the safety of the occupants, the most economical and effective way to achieve lightweight vehicles is to use high-strength steel or advanced high-strength steel on the body. Strengthening elements such as Si, Mn, and Al need to be added to advanced high-strength steels. ...
