In order to investigate the impact of design parameters (depth, width, and location) single-circumferential groove (SCG) on tip leakage flow (TLF) reduction in a transonic turbine stage, systematic investigation was conducted by high-precision numerical simulation method. The results show that introduction SCG could improve stage efficiency (η) significantly. optimal depth coefficient (ζ), width (W), location (L) were ζ = 3, W W3, L 20%Cax (where Cax denotes axial chord blade), which reduce...
A ZrSi 2 –ZrC–SiC/SiC double layer coating was prepared on the surface of carbon/carbon (C/C) composites by pack cementation. The microstructure, oxidation and thermal shock resistance were studied. These results show that outer is mainly composed , ZrC, SiC Si respectively. Oxidation tests conducted in air at 1173 K for 100 min 1773 67 h a weight decrease 0·37 0·12% recorded. After 20 times shocks between room temperature, coated specimens increased only 0·12%. excellent attributed to...
In order to improve the ablation properties of C/C composites, HfC-based coatings with different mass ratios SiC were deposited on surface SiC-coated carbon/carbon composites by supersonic atmospheric plasma spraying. The morphologies and microstructures characterised. resistance test was carried out oxyacetylene torch. results show that as-prepared are multiphase consisting HfC, HfO2, SiO2. structure is dense. After for 60 s, centre region coating smooth without obvious microcrack pinhole,...
In this study, a series of mesoporous TiO2 nanotablets implanted with uniformly distributed MoO3 were formed by the heat treatment titanium-based metal–organic framework (MIL-125) in presence Mo ions, and their hydrogen sensing properties investigated for first time. The MoO3/TiO2 composites present typical tablet-like morphology. Compared bare TiO2, (Mo6+/Ti4+ = 1:10) composite has richer porous structure (3 times larger than pure TiO2) which can provide surface area (2.1 TiO2). performance...
SiC coating was prepared on the surface of C/C–ZrC–ZrB 2 –SiC composites by chemical vapour deposition (CVD). The microstructures and phase compositions were characterised scanning electron microscopy X-ray diffraction respectively. CVD exhibited a dense structure with thickness 30–40 μm. Oxidation behaviour coated sample studied in wind tunnel at 1600°C. Thermogravimetric analysis measured. results show that fractured after being exposed for 21 h. failure is attributed to excessive local...
To prevent carbon/carbon (C/C) composites from oxidation, a phosphate coating was prepared on the by simple and low cost slurry technique. The effect of B2O3/SiO2 mass ratio microstructure oxidation resistant property studied. characterised scanning electron microscopy X-ray diffraction is mainly composed SiO2, BPO4 Al(PO3)3. Oxidation tests show that, as B2O3 SiO2 1∶1, possessed excellent ability. After in air at 700°C for 30 h thermal cycling between 900°C room temperature 50 times, weight...
The success of implants is determined by the cell response to biomaterials and integration into tissue. surface characteristic biomaterial considered as a key factor influence integration. aim this work determine effect various modifications for carbon/carbon (C/C) composites on MG63 responses. Surface modified C/C including rough shaped (RCC), post-deposition treated (PCC) diamond-like carbon coated (DCC) were prepared. characterisation was performed three kinds using scanning electron...
Carbon fibre reinforced magnesium matrix (Cf/Mg) composite components were made by liquid–solid extrusion process following vacuum infiltration technique. The effect of varying fabrication parameters (extrusion temperature, pressure and filling pressure) on the forming quality Cf/Mg was investigated. experimental results showed that temperature played important roles, a secondary role. can be obtained at an 590°C, 20 MPa 0.2 MPa. ultimate tensile strength 290 MPa, which increased 81%...
