  • Deposition of SiC/La2Zr2O7 multi-Component Coating on C/SiC substrate by combining sol-gel process and slurry
    Surface & Coatings Technology, 2016
    Co-Authors: Shengxue Wang, Song Wang, Wei Li, Jian Zhang
    Abstract:

    Abstract Lanthanum zirconate (La 2 Zr 2 O 7 ) has been developed as futuristic thermal barrier Coatings (TBCs) for Si-based ceramic matrix composite combustor and vane applications. The large mismatch of thermal expansion coefficient between La 2 Zr 2 O 7 Coating and composite substrate is a key limitation to this use of TBCs. To solve this problem, SiC/La 2 Zr 2 O 7 multi-Component Coating has been prepared on the C/SiC composites surface by combining sol-gel process and slurry. Well-dispersed, single pyrochlore structured nanoscale La 2 Zr 2 O 7 powders for Coating was synthesized by sol-gel method. The as-prepared SiC/La 2 Zr 2 O 7 multi-Component Coating was well bonded to the substrate, which might be associated with the newly formed La 4.67 (SiO 4 ) 3 O phase, with a uniform thickness of 85.8 μm. The thermal conductivity of the C/SiC composites decreased by 12% to 28% after deposition of SiC/La 2 Zr 2 O 7 multi-Component Coating.

  • Ir-based multi-Component Coating on tungsten carbide by RF magnetron sputtering process
    Surface and Coatings Technology, 2020
    Co-Authors: Fan-bean Wu, Wei-yu Chen, Yi-ying Tsai, Yuan-i Chen
    Abstract:

    [[abstract]]Ir-based noble metal hard Coatings were deposited onto the tungsten carbide substrate by RF magnetron sputtering. Films were prepared by multi-target sputtering with iridium, rhenium and chromium as the sources. Argon and nitrogen were inlet into the chamber to be the plasma and reactive gases. The correlations between contents of each Component in the noble metal alloy films and the control parameters in the input power of the sputtering gun was investigated. The contents of Cr and N ranged from 3.2 to 33.5 at.% and 7.3 to 21.0 at.%, respectively, as the power applied to the Cr source was varied from 50 to 250 W. The atomic ratio of Ir/Re remained constant at 2.0, regardless of the amount of Cr and N co-deposited. The Coating microstructure and morphology were also studied by X-ray diffraction and atomic force microscopy, respectively. It was shown that the surface roughness (Ra) values of uncoated substrate and Ir–Re–Cr–N protective thin film were in the same order of approximately 2–4 nm. Microhardness test indicated that the Ir–Re–Cr–N multi-Component Coating exhibited compatible hardness with the Ir–Re binary hard films, and the surface hardness was better than that of the Ir–Pt film.[[fileno]]2020323010213[[department]]材料科學工程學
