Ceramic Coating

The surface of the piston rods for hydraulic cylinders is one of the critical points in all hydraulic installations. An appropriate combination of base material and processing technology, along with the sealing system used in the corresponding hydraulic enviroment, is essential to optimize durability and cost-effectiveness.

Corrosion of the piston rod surface is one of the main reasons for hydraulic cylinder failure. Once the piston rod surface is corroded replacing seals with new ones is just a temporary relief. Hydraulic cylinders with ceramic coated piston rods has enhanced corrosion resistance properties against corrosive elements present in the environment. If your application doesn't allow down time for hydraulic cylinder maintenance then getting ones with ceramic coated piston rods will save on these down time.

Ceramic Coating adds additional protection to your cylinder's exterior and helps keep it looking like-new with comparatively minimal maintenance. The coating achieves this result by making your cylinder more resilient and easier to clean. Here are the main benefits:

Protection from Harsh Operating Conditions

Hydraulics Cylinders generally operate in a high-temperature and high-pressure operating conditions. With proper ceramic coating can help the cylinder to be anti-corrosion and ensure proper operating. It is usually use mainly in marine, ships, drilling platforms, metallurgical and other harsh environments applications.

Protection from Oxidization

If a cylinder is often exposed in a harsh operating condition, its paint will begin to oxidize, resulting in dulled and faded paint. A layer of Ceramic Coating protects a cylinder's paint from the ultraviolet rays, thereby reducing the amount of oxidization.

Protection from Chemical Stains and Etching

Another danger for your hydraulic cylinder is chemical staining from naturally acidic contaminants. By creating a chemically resistant surface, a Ceramic Coating can keep some contaminants from bonding to your cylinder's paint. The result is that your cylinder will be more resistant to staining and etching, provided the contaminant is removed in a timely manner.

Ease of Cleaning

One of the most significant features of a Ceramic Coating is that it is hydrophobic, which is a fancy way of saying it repels water. When a cylinder has a Ceramic Coating, water will bead on the surface and slide off more easily. This means that the dust will have a more difficult time bonding to your cylinder's paint, and when you need to clean the cylinder, contaminants can be removed with less effort.

Enhanced Gloss

If you want your paint to pop with gloss, you will want to add a Ceramic Coating. A good Ceramic Coating enhances the reflective properties of your hydraulic cylinder's paint and clear coat, adding to the depth and clarity of your paint.
