rusted spring

Mechanical springs often run within harsh environments, which is why spring design is such an integral part of the manufacturing process. One of the most frequent issues that OEMs and those who use springs for particular applications run into is corrosion. Whether it is through consistent contact with water or any other harsh chemicals and substances, corrosion can severely decrease the life and load capacity of springs.

How Corrosion Affects Mechanical Springs

Whether you are working with torsion, extension or compression springs, corrosion affects them all in the same manner. The differences in corrosion only appear when the materials of the springs change. Rust, for example is one of the most common examples of corrosion on springs that are made from steel. Rust is simply oxidized molecules with water, but it is unsightly, and more importantly, it reduces the strength of the metals it affects. When a metal like steel rusts, the steel is replaced with flaky powder. The rust will slowly eat away at the metal until application failure occurs.

How Can You Prevent Rust In Springs

Carbon steels like music wire and chrome vanadium are particularly affected by rust while stainless steels and a few alloys are generally more protected. In the end, it is very hard to guarantee that rust will never build up over time. Simply exposing metal to the air will create rust over time. The best thing a spring engineer can do is delay it.

Over the years, we have adopted and enhanced many techniques that can severely slow down the buildup of rust on mechanical springs. Using the right materials is an important first step, but you can also choose special coatings that are designed to combat rust accumulation and oxidation of metals. These coatings are essential for applications that require certain materials to be used. When you cannot switch out the material, we can cover your springs in coatings that effectively resist rust and other forms of corrosion.

Depending on the material and coating, you can expect short to long-term protection. Keep in mind that more expensive coatings will last longer, as will your springs. It is often better to invest more money at the outset of your springs than to take the time and money to replace them frequently over time.
