Introduction Piston rings play a crucial role in engine performance, ensuring efficient sealing between the piston and cylinder wall. Over the years, advancements in materials and coating technologies have led to the development of ceramic chrome piston rings, which...
The imminent phasing out of chrome coatings, driven by the stringent regulations outlined in the REACH framework, is sending ripples through industries that rely on these coatings for critical applications. From piston rings to bearings, valves to gearboxes, the...
Piston rings have evolved in recent years. Until recently they were heavier, thicker, and made of cast iron. Modern rings are thinner, come in many widths, and must be precisely configured to suit the needs of the user. Coatings play an ever more important role when...
Piston rings are key components in the likes of marine and locomotive diesel combustion engines. The piston ring functions in an incredibly demanding environment, with high mechanical loads, high temperatures, and corrosive compounds all testing the strength and...
One significant factor in piston rings that often goes ignored is the specific material used on the outside of a piston ring. Whilst the lubricant used is often a major area of attention since it’s a significant factor in the amount of friction acting within the...
Choosing to coat your piston rings has been proven to extend their life and improve their efficiency. For example, coating a piston ring can prevent scuffing and reduce corrosion. If, however, you select the wrong coating for your piston rings you can cause excessive...
