Problems solved by technology

Phosphating before painting is an indispensable main process in the pretreatment of metal painting. It can obviously improve the adhesion and protection ability of the coating. It is a pipe fitting technology to ensure the quality of painting. necessary process, but the performance of the phosphating film in the existing phosphating process is average, the phosphating speed is slow, and the service life is low

Abstract

The invention discloses a steel rim vehicle wheel surface phosphating treatment method and relates to the technical field of steel treatment. The method comprises: (1) grinding, (2) cleaning, (3) plasma treatment and (4) phosphating treatment. The method can well protect the steel rim vehicle wheel surface, improve the film forming stability, greatly improve the compactness and uniformity of the phosphated film, realize high phosphated film adhesion, improve the corrosion resistance and wear resistance of the surface of the steel rim vehicle wheel surface, realize high phosphated film purity,facilitate precipitate removal, shorten the conventional high-temperature surface phosphating treatment time, realize fast phosphating treatment at the normal temperature, prevent heating, solve the problem that the conventional high-temperature phosphating treatment method easily causes phosphated film impurities and precipitates difficult to remove, and improve the phosphating efficiency.

Description

technical field [0001] The invention belongs to the technical field of steel processing, and in particular relates to a phosphating treatment process for the surface of a steel rim wheel. 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] At present, metal phosphating treatment technology has been widely used, and has been applied to many fields such as automobiles, completed construction, electrical appliances, machinery, etc. Especially in the field of metal surface coating, the amount accounts for about 60%-70% of the total industrial use of phosphat...
