The objective of this work is to summarize the results of the different tests: environmental (temperature, air, vacuum, steam-ingress) and gamma irradiation, carried out in different materials (candidates for port plug and optical hinge mirrors, vacuum window, field lens and beam splitters), in order to provide information for choosing relevant
The co-sintering temperature range is defined from thermochemical calculations and single material sintering experiments especially for Stellite 6. Finally, the co-sintering ability is evaluated (green and final densities, shrinkage mismatch, coefficient of thermal expansion) and the bimaterial sintering is studied.
Sintering occurs at about 2150 °C in a 1–3 psi atmosphere of flowing argon gas, although some processes utilize relatively high partial pressures of argon or even vacuum up to the sintering temperature. The vacuum furnace is typically constructed of graphite and the components are set on graphite trays or placed in powdered graphite.

Jun 23, 2011 · Following vacuum-impregnation the bodies are heated in a curing step 103 to a peak temperature of between 200° C. to 450° C., and more preferably 250° C. to 400° C. in a nitrogen or another inert gas atmosphere to complete curing and cross-linking in a single step. Next, the green loaves are machined in a step 104 to a desired geometry. As
Mar 27, 2016 · This ensures that every part will see the exact same conditions. The parts enter the furnace at room temperature and exit at room temperature. The interior of the furnace is in a protective atmosphere. Therefore, oxidation is not a problem. The CM Furnace Solution to Continuous Sintering for Production
The sintering process was executed in the inert atmosphere of argon at 1450°C with a 2-hour dwell time at the maximum temperature. Density and strength measurements of the green bodies and sintered samples were made. In order to determine the phase structures before and after the sintering process, X-ray analysis was conducted.
Sintering starts with debinding. The debinding process removes binder materials that can contaminate the furnace and the final product. Binding materials are originally necessary for each separate part compaction, but become unnecessary and undesirable during the sintering process. Vacuum sintering requires a high vacuum for clean, quality parts.
Description: Maximum Temperature: 1900°F / 1083°C The TRENT HM Muffle design box furnace is a small atmosphere furnace used for tool hardening, low-temperature brazing, bright annealing, general metal heat-treating and other processes requiring a controlled atmosphere up to 1900°F.
HIGH VACUUM TURBOPUMP. The addition of the turbopump has transformed the RD-G from a ceramic sintering furnace into a multipurpose laboratory workhorse. Besides sintering ceramics in argon or vacuum, active metal brazing and processing of reactive metals under high vacuum conditions of 10-4 and 10-5 mbar range can be performed.
