June 2016: Hot Zone Designs – Past, Present and Future (Part 1)
The first in the series of 3 podcasts looking back over the evolutionary history of hot zone designs from the beginning of the modern vacuum furnace discussing a few important developments that helped to shape present day furnace technology.
April 2016: Active Brazing of Titanium in a Vacuum Furnace
The April 2016 podcast is the third in the series about Vacuum Furnace Brazing. Our discussion centers on an overview of reactive brazing in a vacuum furnace and the use of active brazing alloys for successful results in joining titanium and titanium alloys.
February 2016: Vacuum Furnace Brazing of Stainless Steels
The February 2016 podcast is the second in the series about Vacuum Furnace Brazing. Our discussion centers on the advantages and concerns of brazing of Stainless Steel components with nickel-based and copper-based brazing alloys.
Vacuum Heat Treat Minute December 2015: The Advantages of Vacuum Furnace Brazing
This podcast is the first in a series on vacuum furnace brazing. It is an overview of the different types of brazing processes and why vacuum furnace brazing is superior to other joining methods, particularly torch brazing and welding.
Vacuum Heat Treat Minute October 2015: Preventing Distortion and Cracking in a Vacuum Furnace
Distortion and cracking of parts is a common problem for heat treaters. This podcast is a discussion on how to prevent and reduce the distortion and cracking of tool steels and other ferrous alloys when cooling parts in a gas-quenching vacuum furnace.
Vacuum Heat Treat Minute August 2015: The Problem of Contaminated Ceramic Electrical Insulators in a Vacuum Furnace
This podcast features a discussion on how contaminants develop on ceramic insulators, how contamination affects the operation and performance of a vacuum furnace, and how to keep ceramic insulators clean of contaminants.
Vacuum Heat Treat Minute June 2015: Measuring and Monitoring Trace Levels of Dew Point and Oxygen in Quench Gases – Part 2
A discussion on the importance of measuring and monitoring the trace levels of dew point (water vapor), oxygen and other gases to reduce part contamination through the use of a residual gas analyzer for in-process vacuum analysis, research and development, and maintenance.
Vacuum Heat Treat Minute April 2015: Measuring and Monitoring Trace Levels of Dew Point and Oxygen in Quench Gases – Part 1
This month’s podcast is Part 1 on the importance of measuring and monitoring the trace levels of dew point and oxygen in quench gases to reduce part contamination while processing in a vacuum furnace.
Vacuum Heat Treat Minute February 2015: Preventive Maintenance – Part 4
This is the fourth and final podcast in a series on the benefits of vacuum-furnace preventive maintenance. The concluding installment is a discussion about the importance of maintaining hot-zone power supplies.
Vacuum Heat Treat Minute December 2014: Preventive Maintenance – Part 3
This installment serves as the third part of our discussion on vacuum-furnace preventive maintenance. Bill Jones advises listeners about how to properly maintain diffusion pumps.
