Název v původním jazyce

Fracture behaviour of alumina-zirconia composites containing microfibers

Popis výsledku v původním jazyce

The ceramic composites containing fibres are usually prepared with the aim that fibres will serve as reinforcement to enhance mechanical properties mainly the fracture resistance of inherently brittle ceramic matrix. In this contribution will be used both alumina and zirconia micro-fibres to help eliminate drying defects in the green body stage before sintering. The co-deposition of ceramic fibres and powder with the targeted final creation of homogenous crack free ceramic material using EPD is unexplored field from the processing, microstructure and as well properties point of view. The alumina powder reinforced with zirconia microfibers will be explored in green state and as well after sintering. The influence of fibres in the matrix before and aftersintering will be described. The micro fibre presence in the matrix effect on the crack propagation will be described. Also the effect of processing parameters mainly the effect of method of fibre homogenisation within the powder suspens
