The invention discloses a surface treatment process of a rear-damping workpiece of a damper for an automobile. The surface treatment process includes the following steps of 1, painting, wherein the surfaces of an oil storage barrel and an outer dust cover of the rear-damping workpiece of the damper are painted; 2, welding, wherein a lifting ring is welded to the dust cover treated in the step 1; and 3, waterborne paint making-up, wherein waterborne paint is sprayed to the welding portions of the lifting ring and the dust cover. In the step 1, a painting method includes electrophoretic painting. Firstly, the rear-damping workpiece of the damper is subjected to electrophoretic painting, the welding portion of the outer dust cover, the lifting ring and other non-electrophoretic paint sprayingsurfaces are subjected to waterborne paint making-up process treatment, a production line can be simplified, the safety and environmental friendliness level is improved, and the cost is reduced. 本发明公开了一种车用减震器后减工件表面处理工艺，包括以下步
