Titanium alloy foil and titanium strip surface treatment method

 

The surface treatment of titanium foil titanium strips, the chemical methods are mainly pickling and alkali-acid washing; mechanical methods, mainly shot peening and abrasive belt grinding. The acid scale is used to remove the scale on the surface of the annealed titanium strip, and the least cold flattening should be performed first, followed by pickling in stages. First, the scale on the surface of the titanium strip is soaked in water, concentrated sulfuric acid, calcium fluoride solution to form a blue film on the surface, rinsed with water, the surface of the titanium strip, and then placed with nitric acid and hydrofluoric acid. In the solution prepared with water, the blue film formed on the surface of the titanium strip is removed to achieve the effect of complete descaling. This method is economical and simple compared to continuous pickling. However, there are still public pollution and environmental pollution problems.

Cold-rolled strip and sheet, high precision, uniform, excellent surface shape, stable, uniform mechanical properties and organization. Surface finishing of cold rolled sheets, strips or foils includes bright processing and matte processing. The former performs surface smoothing and rolling on the leveling machine, and the surface exhibits metallic luster. The latter is matt-finished, the surface is cleaned with weak acid, shot-peeled or sprayed with alumina particles. Due to continuous annealing in the atmosphere, the crystal grain and thickness can be adjusted to control the gloss, so that the material can be used as a roof decoration. material. Other matte processing can be rolled by rolls having fine unevenness.

The titanium foil is processed by soft pure titanium and is cold-rolled using the same flat rolling mill. The thickness of the titanium foil is 0.01 mm, which is the lower limit of the thickness.
