Abstract

The invention discloses a coating process for a transmission shaft spline shaft. The surface of the transmission shaft spline shaft is coated with industrial grease; the transmission shaft spline shaft is put into a controllable atmosphere to be wholly heated to 200 DEG C and kept for 3 hours; the heated transmission shaft spline shaft is quenched with an organic aqueous solution adopted as a cooling medium; the quenched transmission shaft spline shaft is subjected to surface quenching with an organic aqueous solution adopted as a cooling medium; the transmission shaft spline shaft is ground and cleaned; and the transmission shaft spline shaft is put into a mixed solution of stannous mono-sulphate, aluminum chloride and gelatin and coated through a chemical plating method. Compared with the prior art, the coating method provided by the invention not only can prolong the service life of the transmission shaft spline shaft, but also reinforce the overall intensity of the transmission shaft spline shaft, so that the transmission shaft spline shaft has competiveness on the market.

Description

technical field [0001] The invention relates to the field of coating technology of a transmission shaft spline shaft, in particular to a coating technology of a transmission shaft spline shaft. Background technique [0002] Metal mold coating is a mixture of various refractory materials such as corundum and molybdenum trisulfide, which is processed by a special process. It is used for coating the inner wall surface of metal mold cavity and melting tool bell jar, refining frame and aluminum alloy ingot film. Coating to prevent iron infiltration of molten aluminum, improve the service life of metal molds and smelting tools and the quality of aluminum alloys. [0003] In today's coating process of the spline shaft of the transmission shaft, most enterprises only coat a layer of anti-corrosion coating on the spline shaft of the transmission shaft, which is not conducive to the long-term use of the spline shaft of the transmission shaft, and is not conducive to Product competiti...
