“…The Taguchi method also allows the prediction of the output values that can be achieved by setting control-factors at the corresponding optimal configuration [21,26]. Based on the previous discussion, it is expected that the N-CNTs forest with highest I D /I G ratio intensity is obtained at a temperature of 825ºC, 2 min of pretreatment time and 90 sccm flow rate of NH 3 .…”

“…Thermal CVD is a growth technique which involves a large number of tunable parameters, such as the carbon precursor and nitrogen doping source and catalyst, the type of carrier gas and its flow rate, and deposition temperature. The Taguchi methodology involves identification of controllable and uncontrollable parameters and the establishment of a series of experiments to determine their optimal combination, which has the greatest influence on the performance and least variation from the target design [17][18][19][20][21][22].…”

The Taguchi method with a parameter design L 9 orthogonal array was implemented for optimizing the nitrogen incorporation in the structure of vertically aligned N-doped CNTs grown by thermal chemical deposition (TCVD). The maximization of the I D /I G ratio of the Raman spectra was selected as the target value. As a result, the optimal deposition configuration was NH 3 =90 sccm, growth temperature=825ºC and catalyst pretreatment time of 2 min, the first parameter having the main effect on nitrogen incorporation. A confirmation experiment with these values was performed, ratifying the predicted I D /I G ratio of 1.42. Scanning electron microscopy (SEM) characterization revealed a uniform completely vertically aligned array of multiwalled CNTs which individually exhibit a bamboo-like structure, consisting of periodically curved graphitic layers, as depicted by high resolution transmission electron microscopy (HRTEM). The X-ray photoelectron spectroscopy (XPS) results indicated a 2.00 at.% of N incorporation in the CNTs in pyridine-like and graphite-like, as the predominant species.

Hybrid photovoltaic structures based on transparent conductive SnO 2 and electrically conductive polypyrrole (PPy) were prepared. Nanocrystalline SnO 2 is considered an n-type barrier and window layer on p-type PPy layer in cell structures. The surface morphology and thickness of the layers were studied using scanning electron microscopy. The optical absorbance data showed an increase of absorbance in contrast with PPy and SnO 2 . There was a red shift in absorbance wavelengths and a decrease in band gaps for the prepared PV structures. To investigate the electrical properties of the obtained structures, current-voltage characteristic was measured. The best structure showed an open-circuit voltage of 0.170 V, a short-circuit current density of 0.017 mA/cm 2 , a fill factor of 0.36 and power conversion efficiency of 0.076.

Design Optimization of the Aeronautical Sheet Hydroforming Process Using the Taguchi Method

et al. 2019

View full text Add to dashboard Cite

The aluminium alloy sheet forming processes forging in rubber pad and diaphragm presses (also known as hydroforming processes) are simple and economical processes adapted to aeronautical production. Typical defects of these processes are elastic recovery, necking, and wrinkling, and they present difficulties in control mainly due to property variations of the sheet material that take place during the process. In order to make these processes robust and unresponsive to material variations, a multiobjective optimization methodology based on the Taguchi method is proposed in the present study. The design of experiments and process simulation are combined in the methodology, using the nonlinear finite element method. The properties of sheet material are considered noise factors of the hydroforming process, the objective being to find a combination of the control factors that causes minimal defects to noise factors. The methodology was applied to an AA2024-T3 aluminium alloy sheet of 1 mm thickness stamping process in a diaphragm press. The results allowed us to establish the optimal pressure values, friction coefficient between sheet and block, and friction coefficient between sheet and rubber to reduce the elastic recovery variations and the minimal thickness before noise facts.
