Problems solved by technology

[0002] The godet is one of the parts of the sizing machine. The godet of the prior art is to spray ceramics on the surface of the cast iron to make the surface adhere to a layer of black ceramic coating. The spraying method is laser spraying, and physical polishing is used after spraying. The service life of the godet manufactured by the craft is short, generally 5 to 8 months, and the black ceramic coating will wear out or even fall off. Once it falls off, the godet must be replaced to ensure the normal use of the equipment and increase user maintenance. equipment cost

Abstract

The invention discloses a draw-off godet and a manufacturing method thereof. A combined mirror surface layer is arranged on the surface of the draw-off godet, and the combined mirror surface layer is formed by a base layer, a function layer and a running-in layer from inside to outside in sequence. The manufacturing method comprises the following steps of carrying out pretreatment on the surface of the draw-off godet to remove oiliness on the surface, carrying out ultrasonic surface treatment and chemical oiliness removal, carrying out surface activating treatment, using pure water for cleaning, plating phosphorous nickel phosphorous alloy in a chemical mode to form the base layer, depositing nickel phosphorous-silicon carbide particles on the surface of the phosphorous nickel phosphorous based coating to form the function layer, depositing nickel phosphorous alloy on the surface of the function layer to form the running-in layer, and then carrying out final treatment. By means of the technical scheme, three chemical plated layers coat the surface of the draw-off godet, the wear-resistance of the draw-off godet is increased, and the maintaining cost of equipment is reduced.

Description

technical field [0001] The invention belongs to the field of man-made fiber machinery manufacturing, and more specifically, the invention relates to a godet and a manufacturing method thereof. Background technique [0002] The godet is one of the parts of the sizing machine. The godet of the prior art is to spray ceramics on the surface of the cast iron to make the surface adhere to a layer of black ceramic coating. The spraying method is laser spraying, and physical polishing is used after spraying. The service life of the godet manufactured by the craft is short, generally 5 to 8 months, and the black ceramic coating will wear out or even fall off. Once it falls off, the godet must be replaced to ensure the normal use of the equipment and increase user maintenance. The cost of the equipment. Contents of the invention [0003] The problem to be solved by the present invention is to provide a godet which reduces equipment maintenance cost and a manufacturing method thereo...
