Beschreibung
Zusammenfassung:	The invention discloses a hydraulic valve rod and a section function segmentation treatment process thereof, the process comprises the steps of preliminary machining, whole-section chromium plating, segmented deplating, segmented plating and tight machining, and the segmented plating comprises the step of electroplating zinc-nickel alloy on the hydraulic valve rod subjected to segmented deplating. And chromium plating is carried out, and zinc-nickel alloy plating is carried out on the part needing corrosion resistance, so that the hydraulic valve rod meets the requirements for wear resistance and corrosion resistance of the hydraulic valve rod at the same time, and the service life of the hydraulic valve rod is prolonged. 本发明公开了一种液压阀杆及其区段功能分段处理工艺，包括：初步加工、整段镀铬、分段退镀、分段上镀以及紧密加工，所述分段上镀包括：将分段退镀的液压阀杆进行电镀锌镍合金，本发明通过对液压阀杆进行分段上镀，需要具有耐磨的部分，进行镀铬，需要具有耐腐的部分，进行镀锌镍合金，实现液压阀杆同时满足液压阀杆的耐磨与防腐性能要求，提高液压阀杆的使用寿命。
