Hot Zone Design for Vacuum Furnaces

Jeff Pritchard - VAC AERO International Inc., Ontario, Canada

The hot zone is perhaps the most critical feature of a vacuum furnace in terms of its affect on furnace performance and operating cost. There are a variety of hot zone designs and the choice of a design should be based on a careful analysis of specific processing applications.

VAC AERO Adds AerMet® 100 Processing Qualifications

VAC AERO Press Release

AerMet® 100, produced by Carpenter Technology Corporation, is a precipitation hardening alloy based on an iron-cobalt nickel mixture strengthened with carbon, chromium and molybdenum. The alloy is equal in strength to 300M high strength steel but with better fracture toughness and stress corrosion cracking resistance. This makes it ideal for use in aircraft components where weight-savings and reliability in severe environments are critical, such as the landing gear for carrier-based military aircraft.

VAC AERO is a World Leader in the Processing of Landing Gear Components

VAC AERO Press Release

VAC AERO’s Ontario Thermal Processing Division continues to support aircraft landing gear programs large and small.

VAC AERO’s heat treating operation in Oakville, Ontario continues to maintain its position as a world leader in the processing of aircraft landing gear components. VAC AERO is now heat treating critical landing gear components for many large commercial aircraft programs including Boeing 777, 777LR, 747-800 and Airbus A380 (commercial and freighter versions). New contracts for processing Boeing 787 and Airbus A320 landing gear components will be underway this year.

SiC-Reinforced Aluminum Alloy Coatings Produced by Cold Spray Process

Metal matrix composites are becoming increasingly popular for industrial applications as diverse as aerospace, automotive and electronics.  The composites consist of an alloy matrix reinforced with ceramic particles to enhance mechanical properties.  Aluminum alloys are especially popular as a matrix material.
