1 Practical Approach to Determining Effective Case Depth of Gas Carburizing (March/April 2016)

Effective case depth is an important factor and goal in gas carburizing, involving complicated procedures in the furnace and requiring precise control of many thermal parameters. Based upon diffusion theory and years of carburizing experience, this paper calculates the effective case depth governed by carburizing temperature, time, carbon content of steel, and carbon potential of atmosphere. In light of this analysis, carburizing factors at various temperatures and carbon potentials for steels with different carbon content were calculated to determine the necessary carburizing cycle time. This methodology provides simple (without computer simulation) and practical guidance of optimized gas carburizing and has been applied to plant production. It shows that measured, effective case depth of gear parts covering most of the industrial application range (0.020 inch to over 0.250 inch) was in good agreement with the calculation.

2 Powder Metallurgy Innovations (September/October 1999)

Powder metal. To gear makers today, the phrase conjures images of low power applications in non-critical systems. As powder metal technology advances, as the materials increase in density and strength, such opinions are changing. It is an ongoing, evolutionary process and one that will continue for some time. According to Donald G. White, the executive director of the Metal Powder Industries Federation, in his State-of-the-P/M Industry - 1999 report. "The P/M world is changing rapidly and P/M needs to be recognized as a world-class process - national, continental and even human barriers and prejudices must be eliminated - we must join forces as a world process - unified in approach and goals."

10 Documentation: A Challenge in Making Aerospace Gears (March/April 2020)

For years, Reliance Gear Corp. has manufactured gears for the aerospace industry. Located in Elmhurst, IL, Reliance has served as a Tier 2 or Tier 3 supplier. (Tier 1 suppliers work directly with the aerospace primes, the Boeings and Embraers of the world.) Like many gear shops, Reliance is certified under quality management standard ISO 9001. And its aerospace customers were satisfied with that certification. Until two years ago.
