Through its extreme hardness, BALINIT® DLC provides excellent protection against abrasion, tribo-oxidation and adhesive wear, whilst permitting high surface pressures that would otherwise quickly cause scuffing and cold welding.

Diamond-like carbon (DLC) coatings are perfectly suited to the most extreme wear conditions and high sliding speeds, even without lubrication. They minimise frictional losses, making them ideal for engine components such as fuel injection systems, valve trains and pistons. Many other applications, ranging from pumps and compressors to bearing shells and rollers, and from textile machines to medical technology, also exploit the outstanding gliding properties of DLC coatings.
