Partial Pressure Vacuum Processing – Part II: Applications
This article is based on a presentation at the Furnaces North America ’96 Conference, held in Dearborn, MI, September 24-26, 1996 and sponsored by Industrial Heating. In part two, partial pressure vacuum processing cycles for different materials are reviewed. Information regarding the evaporation of base metals and reactive processing was presented in the September ’97 issue of Industrial Heating.
Partial Pressure Vacuum Processing – Part I
This article is based on a presentation at the Furnaces North America ’96 Conference, sponsored by Industrial Heating. In the first part of this two-part series on partial pressure processing, techniques for controlling evaporation of base materials and reactive processing are discussed. In Part II, actual applications for production operations will be presented with full process cycles and descriptions.
The Advantages of Ion Nitriding Gears
Ion Nitriding gears has the potential to eliminate the need for expensive post-heat treatment operations. The advantages of ion nitriding compared to conventional hardening methods are presented from the point of view of a custom gear shop executive and a heat treater.
Vacuum Brazing: A Three in One Process that Provides Efficiency
Different metal joining processes each have advantages and applications for which they are best suited. An often overlooked capability of vacuum brazing is the simultaneous combining of three metal treatments in one process: bonding, cleaning and heat treating.
Vacuum Heat Treating for M2 High Speed and D2 Tool Steels
A series of large cross section D2 and M2 tool steels have been obtained and cross cut prior to heat treatment. Similar heat treating, time and temperatures, will be run in a salt bath furnace and a vacuum furnace. All parts will be tracked for process temperature via deep imbedded thermocouples. Data reported, including metallurgical results, for an independent laboratory.
Optimizing Gas Quenching
Gas type and pressure, blower motor power, and furnace design features are among the important factors to consider when choosing a vacuum furnace gas quenching system.
Energy Dominates in Job Costing
Job costing can sometimes be a tedious task, however, it is a necessity if a business is to understand its true costs and predict its profits. Using a vacuum anneal heat treating cycle, as an example, costs can be identified by category, permitting a total cost to be calculated for the job. The seven specific topics covered are the initial cost of equipment, electric utilities, labor, process gases, fixturing, water cooling systems and maintenance.
Brazing of Electric Power Interrupters in Vacuum Furnace Specially Designed for the Process
William R. Jones, David Rinz and Real Fradette, Vacuum Furnace Systems Corporation, August 1994 - Four vacuum furnaces, specially designed by engineers of Vacuum Furnace Systems Corp, Souderton PA to braze electric power interrupter assemblies of the vacuum arc suppression type are described.
Product Quality Improvement With Correct Moisture Measurement in Thermal Processes Using Electrolytic Hygrometers
Moisture analysis at different phases of the heat treat process is crucial as even trace amounts of oxygen and water vapor can lead to oxidation of the materials being processed. This paper explores why moisture reduction is critical and how to properly calibrate and operate an electrolytic hygrometer to monitor moisture in vacuum heat treating.
