Abstract:
The chemical vapor infiltration using the so-called Hybrid System Chemical Vapor Deposition process (HYSYCVD) allows the synthesis and deposition of fibers, whiskers and powders at submicron- and nano-scales within the interstices of porous ceramic structures. The aforementioned process is based on the thermal decomposition of solid precursors at relatively low temperatures. The products of the decomposition react with a gas precursor such as nitrogen N2, giving place to new phases. In this work authors investigate the effect of temperature and time on the microstructural characteristics of the ZrN infiltrated and deposited within silicon carbide (SiC) porous performs. The solid-gas precursors are K2ZrF6 and N2, respectively.
