摘要

So far research on ceramic nanocomposites was focussed on materials science aspects neglecting the development of suitable manufacturing technologies. The high performance properties of nanocomposites make final machining unaffordable. Near-net-shape manufacturing is mandatory to accomplish cost targets. Feedstocks with tailored micro-nano architecture can fulfil these requirements, using homogeneously dispersed nanosizcd powders in a matrix of sub-micron sized grains. Nanoceramic coatings deposited by thermokinetic deposition processes open new prospects and applications in surface technology. The novel HVSFS-process permits direct spraying of liquid nanodispersions in a HVOF torch yielding ultradensc and thin oxide and cermet coatings for automotive, aerospace and mechanical engineering.
