×
BALIQ® CARBOS - Valve train group
BALIQ® CARBOS on cam shafts for racing engines show improved performance when compared to conventional hydrogenated DLC coatings
BALIQ® CARBOS or BALIQ® CARBOS STAR on finger followers show superior wear resistance to hydrogenated DLC coatings at highest contact pressures
Piston pins of racing engines coated with BALIQ® CARBOS or BALIQ® CARBOS STAR show less wear and higher lifetime compared to hydrogenated DLC coatings
BALIQ® CARBOS - Valves and piston ring
BALIQ® CARBOS is the superior coating against very abrasive fibres due to its high hardness and low surface roughness
BALIQ® CARBOS - The flow of intelligence
BALIQ® CARBOS - The amorphous carbon coating that goes beyond DLC

Oerlikon Balzers’ amorphous hydrogen-free carbon (a-C) BALIQ® CARBOS coating features an exceptional combination of high hardness, low friction and low roughness.

BALIQ® CARBOS outperforms hydrogenated DLC coatings in many engineering applications with extreme contact pressures and sliding velocities. With a high proportion of tetrahedral bonds (50-60%), BALIQ® CARBOS provides substantially higher abrasive wear resistance than standard DLC´s (a-C:H).
