-Suspension systems serve to keep the car wheels in contact with the road, while also providing comfort for the driver and passengers. An important part of some suspension systems are helical springs that compress and elongate to support the vehicles movement. Like any other part of the car wear and tear is common in springs as well and it reduces service life and often causes spring failure. This paper studies the effect of providing an electroless nickel coating on helical springs by comparison of coated and uncoated springs through CAD modelling and static stress analysis using FEA. The results show reduction in overall stress values for coated spring.
