Abstract:
A belt for a continuously variable transmission (CVT) includes at least one continuous band supported against a contact face in a slot formed in each of a plurality of transverse elements of the CVT. The band has a surface positioned against the contact face. This surface is coated with chromium nitride by physical vapor deposition to reduce wear.
