Abstract

The invention discloses a surface phosphating solution for a steel rim vehicle wheel and relates to the technical field of steel treatment. The surface phosphating solution for a steel rim vehicle wheel contains 4-6% by mass of nanometer diatomite loading calcium ions and sodium alginate. Before use of the surface phosphating solution, a certain amount of ozone is added into the surface phosphating solution for a steel rim vehicle wheel. The surface phosphating solution can form a compact and uniform phosphated film on the steel rim vehicle wheel surface. The surface phosphating solution has afast film forming speed. The film is uniform and fine, and has good corrosion resistance, good adhesion to the surface of the steel rim vehicle wheel substrate and high surface wear resistance.

Description

technical field [0001] The invention belongs to the technical field of steel processing, and in particular relates to a surface phosphating solution for steel rim wheels. Background technique [0002] The steel rim wheel is the wheel hub, which is a barrel-shaped metal part that is supported by the inner profile of the tire and is centered on the shaft. The surface of the steel rim wheel that has just been processed is surface treated to improve the surface mechanical properties of the steel rim wheel, but the existing surface treatment process of the steel rim wheel cannot meet the needs of long-term work in some harsh environments. [0003] Phosphating is a process in which chemical and electrochemical reactions form a phosphate chemical conversion film, and the formed phosphate conversion film is called a phosphating film. Phosphating has good adsorption capacity and good corrosion resistance, and is widely used in the protection of steel parts and the bottom layer of pa...
