[Surface morphology of alloys treated with the Rocatec system]

The new Rocatec-System is propagated for improving the resin metal bond. With a tribotechnical blasting procedure a silicate layer is applied to the alloy surface. The resin is bonded to this layer with a silane coupling agent. This study investigates the alloy surface morphology alterations caused by the blasting procedures. The volume loss increases with blasting time, high gold alloys showing higher volume loss. Thin edges are deformed due to the high blasting pressure.
