CVD growth of ZrC layers at different temperatures.

Alawad, BAB; Biira, Saphina; Bissett, H; Nel, J. T; Hlatshwayo, T. T; Crouse, P. L; Malherbe, J. B (Busitema University ; SciEP, 2016)

Zirconium carbide (ZrC) layers were grown on a graphite substrate by chemical vapour deposition (CVD) at 1250°C, 1300°C and 1350°C. Zirconium tetrachloride (ZrCl4), methane (CH4), hydrogen (H2) and argon (Ar) were used as ...
Design and fabrication of a chemical vapour deposition system with special reference to ZrC layer growth characteristics

Biira, Saphina; Crouse, P.L.; Bissett, H.; Hlatshwayo, T.T.; van Laar, J.H.; Malherbe, J.B. (2017)

The overall aim of this research project was to design and construct an inhouse, thermal chemical vapour deposition (CVD) reactor system, operating at atmospheric pressure. Radio frequency (RF) induction heating was ...
Effect of temperature and CH4/ZrCl4 molar ratio on ZrC layers deposited in a vertical-wall CVD system

Biira, Saphina; Alawad; Bissett, H; Nel, J. T; Hlatshwayo, T. T; Crouse, P. L; Malherbe, J. B (Busitema University ; SA Institute of Physics, 2016)

The synthesis of ZrC layers was performed in an in-house developed, vertical-wall chemical vapour deposition (CVD) system operating at atmospheric pressure. Zirconium tetrachloride and methane were used as zirconium and ...
Influence of the substrate gas-inlet gap on the growth rate, morphology and microstructure of zirconium carbide films by chemical vapour deposition.

Biira, Saphina; Alawad, B.A.B.; Bissett, H.; Nel, J.T.; Ntsoane, T.P.; Hlatshwayo, T.T.; Crouse, P.L.; Malherbe, J.B. (Busitema University ; Elsevier, 2017)

The influence of the gap between the gas inlet and the substrate in an in-house developed thermal chemical vapour deposition (CVD) reactor, on the growth rate, surface morphology, phase composition and microstructure of ...
Investigating the thermal stability of the chemical vapour deposited zirconium carbide layers

Biira, Saphina; Thabethe, T.T.; Hlatshwayo, T.T.; Bissett, H.; Ntsoane, T.; Malherbe, J.B. (Busitema University ; Elsevier, 2020)

The effect of thermal treatment on zirconium carbide (ZrC) layers deposited by chemical vapour deposition process was investigated using X-ray diffraction (XRD), Raman spectroscopy, nanoindention and scanning electron ...
Optimisation of the synthesis of ZrC coatings in a radio frequency induction-heating chemical vapour deposition system using response surface methodology.

Biira, Saphina; Crouse, PL; Bissett, H; Alawad, BAB; Hlatshwayo, T. T; Nel, J. T; Malherbe, J. B (Busitema University ; Elsevier, 2017-01-11)

A chemical vapour deposition process using radio frequency induction heating operating at atmospheric pressure was developed for the deposition of ZrC coatings. The precursors utilised in this process were zirconium ...
The role of ZrCl4 partial pressure on the growth characteristics of chemical vapour deposited ZrC layers

Biira, Saphina; Crousec, P. L.; Bissettd, H.; Hlatshwayoa, T. T.; Njoroge, E.G.; Neld, J. T.; Ntsoaned, T. P.; Malherbe, J.B. (Elsevier, 2017-04-21)

ZrC layers were deposited in a chemical vapour deposition (CVD) reactor on graphite substrates using a ZrCl4- Ar-CH4-H2 precursor mixture. The deposition was conducted at different ZrCl4 partial pressures at a constant ...
