Chrome plating,CR
The electrodeposited hard chrome coating combines excellent wear resistance with high resistance to scuffing. This accounts for the superiority of chromed rings to uncoated rings and surface treated rings. Experience shows that a chromed ring reduces wear of the cylinder running surface to about 50% and wear of the whole ring pack to about 30% the values obtained with nonchromed rings.
Molybdenum Coating,MOL,MO
To avoid scuffing the periphery of the rings is coated with molybdenum, a process that has yielded excellent results. Molybdenum has a very high melting point(2620°C) and good thermal conductivity, factors which account for the high resistance to scuffing and scoring. Another advantage is the porous structure which forms as the molybdenum is sprayed on, as this promotes good lubrication.
Plasma Spray Coating,PS
In this process the coating materials are melted in a plasma flame at very high temperatures (up to about 15000°C) and sprayed onto the ring running surface. At such high temperatures almost all elements can be melted, enabling the production of metallic, metal-ceramic and all ceramic mixed coatings with different characteristics.Plasma spray coatings, which possess high wear, scuff and breakout resistance and high inherent strength, while causing only limited cylinder wear, are today used very successfully in production.
Phosphating,P
The process is employed to speed up and improve seating-in of the rings. The surface of the ring is transformed by chemical treatment to phosphate crystals
Nitriding,NT
Surface treatment by nitriding to reduce wear of compression rings (mainly steel rings).
Chromium-Ceramic Coating, CK
The CK coating withstands higher thermal and mechanical loading than the exisiting chromium, molybdenum and plasma coatings, though these tried and tested coatings lose none of their significance. In the appropriate designs they continue to satisfy the special demands in the tribological system.
