Small punch creep testing of thermally sprayed Stellite 6 coating: A comparative study of as-received vs post-heat treatment (2019)
Journal Article
Jackson, G., Bai, M., Pala, Z., Hussain, T., & Sun, W. (2019). Small punch creep testing of thermally sprayed Stellite 6 coating: A comparative study of as-received vs post-heat treatment. Materials Science and Engineering: A, 749, 137-147. doi:10.1016/j.msea.2019.02.030

Thermally sprayed Stellite 6 coatings offer high wear and corrosion-erosion resistance at high temperature but the creep behaviour of such coatings is not well understood. In this paper, the microstructure and creep behaviour of a HVOF Stellite 6 coa... Read More

Preparation of MCrAlY-Al2O3 composite coatings with enhanced oxidation resistance through a novel powder manufacturing process (2019)
Journal Article
Bai, M., Song, B., Reddy, L., & Hussain, T. (2019). Preparation of MCrAlY-Al2O3 composite coatings with enhanced oxidation resistance through a novel powder manufacturing process. Journal of Thermal Spray Technology, doi:10.1007/s11666-019-00830-y

MCrAlY-Al 2 O 3 composite coatings were prepared by using high velocity oxygen fuel (HVOF) thermal spraying with bespoke composite powder feedstock for high temperature applications. Powder processing via a suspension route was employed to achieve a... Read More

Investigation on time-dependent wetting behavior of Ni-Cu-P ternary coating (2018)
Journal Article
Wang, J., Liu, J., Neate, N. C., Bai, M., Xu, F., Hussain, T., …Hou, X. (2018). Investigation on time-dependent wetting behavior of Ni-Cu-P ternary coating. Journal of Alloys and Compounds, 765, doi:10.1016/j.jallcom.2018.06.239. ISSN 0925-8388

Hydrophobic metallic coatings have attracted increasing interest in the recent years due to their excellent mechanical durability. But the wetting behavior and hydrophobic mechanism of metallic coatings are far from clear. In this work, Ni-Cu-P terna... Read More

Robust hydrophobic surfaces from suspension HVOF thermal sprayed rare-earth oxide ceramics coatings (2018)
Journal Article
Bai, M., Kazi, H., Zhang, X., Liu, J., & Hussain, T. (2018). Robust hydrophobic surfaces from suspension HVOF thermal sprayed rare-earth oxide ceramics coatings. Nature, 8, doi:10.1038/s41598-018-25375-y. ISSN 0028-0836

This study has presented an efficient coating method, namely suspension high velocity oxy-fuel (SHVOF) thermal spraying, to produce large super-hydrophobic ceramic surfaces with a unique micro- and nano-scale hierarchical structures to mimic natural... Read More

Laser clad and HVOF sprayed Stellite 6 coating in chlorine rich environment with KCI at 700 °C (2017)
Journal Article
Pala, Z., Bai, M., Lukac, F., & Hussain, T. (in press). Laser clad and HVOF sprayed Stellite 6 coating in chlorine rich environment with KCI at 700 °C. Oxidation of Metals, doi:10.1007/s11085-017-9776-7. ISSN 0030-770X

Laser clads and HVOF coatings from a stellite 6 alloy (Co–Cr–W–C alloy) on 304 stainless steel substrates were exposed both bare and with KCl deposits in 500 ppm HCl with 5% O2 for 250 h at 700 C. SEM/EDX and PXRD analyses with Rietveld refinement we... Read More
