Transient Liquid Phase Bonding (TLPB) process of semi-solid metal 7075 aluminum alloys (SSM7075) using 50 μm thick of ZA27 zinc alloys as interlayers for the experiment were carried out under bonding temperatures of 480 and 540 °C and bonding times of 30, 60, 90 and 120 min respectively. In the bonding zone, the semi-solid state of ZA27 zinc alloy interlayers were diffused into the SSM7075 aluminum alloy. Examination of the bonding zone using Scanning Electron Microscope (SEM) and Energy-dispersive X-ray spectroscopy (EDS) showed that the precipitation of the intermetallic compound of η(Zn–Al–Cu), β(Al2Mg3Zn3), T′(Zn10Al35Cu55) and MgZn2 were formed in the bonding zone. The better homogenized microstructure in the bonding zone was formed when increasing bonding time and bonding temperature. The highest bonding strength was recorded at 17.44 MPa and average hardness was at 87.67 HV with the bonding time of 120 min and temperature at 540 °C. Statistically, the coefficient of determination analysis of bonding strength data was at 99.1%.

Abstract. In this study, the use of liquid-phase plasma discharge (LPPD) technology to accelerate the transesterification process was explored. An innovative LPPD reactor was first evaluated by varying the conductive opening size on the dielectric plate (0.75, 1.0, and 1.25 mm) coupled with five methanol to oil molar ratios (MOMR; 3, 4, 5, 6, and 7) and two liquid flowrates through the reactor (2.7 and 4.1 mL s-1) at a given catalyst (NaOH) to oil ratio (NaOR) of 0.8% (w/w). The optimal combination of opening size (1.0 mm), MOMR (5), and flowrate (2.7 mL s-1) was then fixed while the NaOR was varied from 0.4% to 1.2% (w/w) in 0.2% increments to determine the best NaOR for the reactor. The results showed that the best combination of the four operating parameters was an opening size of 1.0 mm, MOMR of 5, liquid flowrate of 2.7 mL s-1, and NaOR of 0.6% (w/w), with which a biodiesel conversion rate of 99.5% was obtained at an applied voltage of 1.2 kV. The transesterification reaction time was found to be only 923 ms. The developed LPPD technology has potential to position biodiesel competitively against petroleum diesel.
