A Comprehensive Guide to Ceramic Metal Piston Rings

For modern marine engines, managing the challenges of low-sulfur fuels is essential for maintaining performance and longevity. One of the most effective solutions is found in an advanced component: Ceramic Metal Piston Rings. These rings are designed to provide superior protection against wear and damage, ensuring your engine runs smoothly even in demanding conditions.

Ceramic Metal Piston Rings: The Ultimate Guide

Why Ceramic Metal Piston Rings?

Operating with modern, low-sulfur fuels (such as VLSFO and ULSFO) can increase the risk of scuffing and seizures in engine cylinders. Ceramic Metal Piston Rings were developed as a robust countermeasure to these issues, offering a new level of protection for your engine’s critical components.

This composite coating, known as Cermet, combines the best properties of both ceramic and metal. The metallic part provides high elasticity and durability, while the ceramic part contributes exceptional resistance to high temperatures and seizure. Together, they form a material with superior wear resistance and toughness, which is vital for long-term engine health.

The use of Cermet technology significantly reduces the risks associated with low-sulfur fuel oils and helps minimize potential cylinder lubrication issues. For specific engine types, an additional layer of chrome on the underside of the rings provides extra protection for the piston crown.

A key advantage of Ceramic Metal Piston Rings is their ability to withstand a momentary breakdown of the oil film. Should such an incident occur, the rings are designed to continue performing, which ensures that engine operation can be safely maintained until the next scheduled overhaul.

As a result of their proven effectiveness, Ceramic Metal Piston Rings are now standard on our new engines and are highly recommended for all engines in service.
