A vehicle suspension element with a coating, a method of depositing the coating, and a coating composition for this method are provided. The vehicle suspension element comprises a coating (11) containing a reticulated polymer matrix (11E) containing polyepoxide and having a minimum thickness equal to at least 120 μm. Methods for depositing the coating (11) on the vehicle suspension element include a step of providing the suspension element to be coated (101) and a step of preheating the surface of the suspension element to a preheating temperature equal to at least 80 ° C. (103). A step of depositing a crosslinkable composition containing an epoxy compound on the preheated surface of the suspension element (104), and heating the surface of the suspension element to a temperature higher than the preheating temperature in order to crosslink the composition. This includes the step of obtaining a coating (105). The suspension element can be, in particular, a steel coil spring. |
