Abstract
The tribological behavior of alternating-layered diamond-like carbon (DLC) films was examined under a variety of humid conditions.Alternating deposited layerswith Si-incorporatedDLC (Si-DLC) and DLC films were prepared using a hybrid coating system. The residual stress of the alternating-layered films was reduced while the hardness was relatively less dependent on the number of alternating-layered sets.Aball-on-disk type tribological test was carried out under the following humid conditions: dry, 50% and 90% relative humidity. The friction coefficient for higher number of alternating- layered sets decreased with increasing humidity conditions but there was no dependency on the wear rate.
