Ceramic multilayer composites have been developed in recent years to enhance toughness and reliability of ceramics. It has been demonstrated by theoretical as well as experimental means, that surface compressive stresses protect the composite against the negative action of surface flaws. The behavi

A new concentric rectangular laminated structure was designed and fabricated by slip-casting method and densified by pressureless sintering process. One class of laminates consists of layers of Si 3 N 4 with 7 wt.% Y 2 O 3 and 3 wt.% Al 2 O 3 as sintering aids, and of interlayers consisting of 50 wt
## Abstract Differently prepared Si~3~N~4~ based ceramics were examined from different aspects of the tribological behaviour: Mechanical and microstructural characteristics have been studied investigating the possible effect of a post heatβtreatment process on the wearing properties. Vacuum tribome
