In this study, the effect of Fe content on the abrasion behavior of TiC–Fe nanocomposite coatings applied on the CK45 steel substrate by air plasma spray method was investigated. For this purpose, milled TiC powder was prepared at 1, 2, 3 and 4 h milled TiC powder for 4 h was selected as the suitable sample. In the next step, a suitable sample mixture with different iron powder concentrations of 5, 10, 15, 20 and 25% was prepared by mechanical milling. The granulated mixture was applied to the substrate using air plasma spray technique. Microstructural and phase analyzes were performed using X-ray diffraction (XRD) and Scanning Electron Microscopy (SEM). According to the results of Williamson-Hall calculations, the TiC crystallites' size decreased by 49 nm–29 nm, and network strain reached 0.16% by increasing milling time from 1 h to 4 h. Studies have shown that the coatings contain titanium carbide, iron oxide, and titanium oxide, with the number of phases formed depending on the amount of iron in the chemical composition. Investigation of the tribological properties of the coating layer showed that with increased iron content in the coating, the wear resistance of the samples is reduced. Hardness tests on coatings indicate that adding iron to nanocomposite from 5 to 25% reduces hardness from 1025 to 699 Hv. It can be argued that a slight increase in the adhesion strength of the coating to the substrate is due to increased wettability because of the formation of molten iron in the coating. 相似文献

Influences of the processes on the microstructures and properties of the plasma sprayed IT-SOFC anode 总被引:1,自引:0,他引:1
By using the atmospheric plasma spraying (APS) technique for SOFC fabrication, we can avoid the thermal failure between the components of SOFC which made from the traditional sintering method at high temperature. The advantage of porous metal supported SOFC produced by the APS process is that the process is simple and low cost. The purpose of this study was to manufacture a porous Ni/CeO2 anode of intermediate temperature SOFC. By introducing the pore former into the feedstocks, the porous structure of the Ni/CeO2 anode was obtained by plasma spraying method. In this study, the feedstock of the NiO/CeO2/Na2CO3 powder made by the spray granulation is spherical; the powder structure is compact and a hollow hole inside the powder, hence more porosity (29.1%) of the as-sprayed coating was found and the pore distribution is more uniform. The remainder oxygen vacancies are existed in the reduced anode coating. Use of undoped ceria as an anode material appears to be feasible. The NiO/CeO2/Na2CO3 powder formed the higher bonding strength coating with 33.6 MPa. The electron conductivity was obtained with around 200 S/cm in 700 °C. The other properties of the anode were discussed in the paper. 相似文献
