Thursday, May 29, 2014, 18:16, Cameron Hodgins, , , TARGET BOAT, In progress, Sintering several carbides on tantalum foil backing
|
Purpose: Sinter one sample of each of TiC, VC, Cr3C2, ZrC, NbC, Mo2C, TaC, and WC on 5x10 mm tantalum foil to see if the samples are usable for SEM.
Samples were prepared using a solution of PEG (2.56 g), PVB (2.45 g), paraffin oil (1.12 g), MEK (15 mL), and EtOH (23 mL). Slurries made using
0.0013 mol of each carbide with ~230 uL of the solution. Applied via paintbrush onto 5x10 mm tantalum foil. |

Pressure down to 7.1e-7 Torr. Water valve to heat shield was opened; pressure remained stable.
Current turned up to 40 A for now. Will increase at 2 A/min up to 500 A over the weekend, then on Monday we will turn it up to 600 A and
check the temperature. |

Auto-ramp started. Max current = 500 A, voltage = 11.05 V. Current is being increased at 2 A/min. In the first 20 minutes, the pressure went up to about
10E-6 T, but has slowly decreased since then. Everything looks ok. The system will be left until Monday morning (June 9th). |

Monday, June 09, 2014, 13:56, Cameron Hodgins, , , TARGET BOAT, In progress, Sintering several carbides on tantalum foil backing

Manually changed current from 500 to 615 A, monitoring the temperature. Temperature went from 1657 C up to 1838 C. Pressure increased up to 7.2e-7 T.
Samples should be left for about 4 hours (615 A started just before 13:00), then the goal is to ramp current back to zero. |

Temperature measurements in progress this week for Ta HP-SIS.
See attachment for the current settings and rampings of the TGHT/TBHT for the temperature measurements taken on Jan. 9-10, 2016 .
Note: TBHT PS tripped off on Jan. 9, 2016 (see first page of the attached file) and couldn't turn it ON again over the week-end. |
