Beschreibung
Zusammenfassung:	A synchronizing ring (1) has a slide region (3) with a thermally sprayed wear resistant tribological coating (4) containing titanium dioxide. A synchronizing ring (1) has a slide region (3) with a thermally sprayed wear resistant tribological coating (4) containing at least 40 wt.% titanium dioxide. An Independent claim is also included for application of the coating (4) described above by thermal spraying of a material containing at least 40 wt.% titanium dioxide. Preferred Features: The coating (4) contains titanium dioxide particles of \}5 mu size as well as tin, zinc, copper and/or aluminum and is applied by arc spraying using a filled wire, optionally together with a solid wire, especially of CuAl8. Die vorliegende Erfindung betrifft einen Synchronisierring mit einem einen Gleitbereich aufweisenden Ringkörper, wobei der Gleitbereich mit einer verschleißfesten tribologischen Beschichtung versehen ist. Erfindungsgemäß ist vorgesehen, daß die tribologische Beschichtung eine thermisch gespritzte Beschichtung ist, die mindestens etwa 40 Gew.-% Titandioxid enthält. Die Beschichtung ist verschleißfester als die üblichen Sinterfolien und komfortabler als Beschichtungen aus Molybdänsystemen.
