“…Sun et al synthesized ZrC nanoparticles reinforced carbon (ZrC/C) composite coatings by CVD using ZrCl 4 C 3 H 6 H 2 source with an Ar carrier gas. 18) They reported that ZrC/C microstructure comprised nano-sized ZrC particles embedded in the carbon matrix with the morphology as same as pyrolytic carbon, because the nucleation of pyrolytic carbon by the decomposition of C 3 H 6 is prior to that of ZrC. In the present study, the decomposition of the Zr(NEtMe) 4 single source simultaneously contributed to the nucleation of both fcc-ZrCN and carbon, resulted in the formation of the dendritic microstructure comprising nano-sized fcc-ZrCN grains with finely dispersed carbon.…”

The vapor-phase growth of zirconium carbonitride (ZrCN) on carbon substrates was demonstrated by laser chemical vapor deposition using an alkyl-amide precursor as a single source. The effects of deposition temperatures on the phase formation, microstructure, chemical bonding states, and deposition rates of ZrCN layers were investigated. An amorphous layer with a large amount of oxygen impurity was deposited at a temperature of 1373 K, whereas a crystalline ZrCN phase with a face-centered cubic structure (fcc-ZrCN) was formed with an excess amount of free carbon at a deposition temperatures of 1453 K. The fcc-ZrCN layer had cone-like nodular morphology with a dense cross section, where the dendritic microstructure comprising nano-sized ZrCN grains with finely dispersed carbon was formed in the fcc-ZrCN layer at 1453 K. The deposition rate of the fcc-ZrCN layer was 40¯m h ¹1 .

The graphitic phases detected in chemical vapour deposited (CVD) ZrC layers were characterized by glancing angle X-ray diffraction. The layers were deposited at different temperatures ranging from 1250 to 1450°C in steps of 50°C. The precursors used were ZrCl 4 and CH 4 in the presence of hydrogen and argon. A total of seven graphitic phases were detected, five of which have been reported in the literature. However, two new hexagonal graphitic phases, P-6m2 (187) and P-62c (190), were also detected. It is proposed that the appearance of these two (new) phases was due to the influence of impurities in the growth region on the growth kinetics. A comprehensive phase identification process was followed to index all observed diffraction lines, followed by Rietveld analysis, to report on phase composition and crystalline properties. A distinct increase in overall graphite phase composition is observed at the higher CVD temperatures, which confirms the impact from graphitization.
