Reasons for Coatings on Medical Devices

Medical device coatings are done for a variety of different reasons. Some of the main reasons include things like corrosion protection, increasing radiopacity, hardening, or just to improve the aesthetic appeal of a particular device. While there are quite a few different metals to choose from, most companies that offer plating services can provide recommendations based on past experiences.

Here is a deeper look into some of the main reasons that hospitals and medical professionals have their medical devices coated:

Corrosion Protection

The most popular coating option for when corrosion protection is absolutely necessary is gold. This is due to the fact that gold is resistant to corrosion and can perform at high levels over a long period of time without breaking down or rusting.


Sometimes it is necessary to have a particular medical device coated with a metal for the purpose of increasing radiopacity. Just about any metal will be able to serve this purpose, although silver seems to be the most popular option.


Medical device coatings may also be required in instances where a device needs to be made to be harder and more durable. While there are dozens of different devices that this can be done for, some of the most common include coils, pins, surgical handles, and even dental brackets.


While most coatings are actually necessary as they improve the overall performance or efficiency of a particular device, there are also instances where aesthetic appeal is the reason for a coating. This is most often done in instances where a particular device has begun to corrode but is still in fine working condition as patients would obviously not feel very comfortable being treated with a unappealing device.

The Final Reason

These are just a few of the many reasons that medical devices are coated with different types of metal. As has been mentioned, the exact metal that is used on a particular device will depend on what that device is intended to do. Companies like ProPlate can also create custom solutions for plating projects that help them to further satisfy the unique needs of their customers.
