How Gears Fail

Heat treatment plays an important — some would say critical — role in gear manufacturing. Therefore, there is a need to better understand, from the perspective of the heat treater, the contribution of heat treatment to gear failures. Aspects such as design, material, heat treatment, and service application all provide examples that serve as an […]

Heat Treat Process For Gears

Heat treatment is a critical and complex element in the manufacturing of gears that greatly impacts how each will perform in transmitting power or carrying motion to other components in an assembly. Heat treatments optimize the performance and extend the life of gears in service by altering their chemical, metallurgical, and physical properties. These properties […]

Typical Heat Treatment Defects of Gears and Solutions Using FEA Modeling

Steel gears are heat treated to obtain enhanced properties and improved service performance. Quench hardening is one of the most important heat treatment processes used to increase the strength and hardness of steel parts. Defects seen in quenched parts are often due to high thermal and phase transformation stresses. Typical defects include excessive distortion, surface […]

Tighter Control Through Understanding What Your TUS Reports Are Telling You

Temperature uniformity is the temperature variation (usually expressed as ± degrees) within the qualified furnace work zone (Figure 1) with respect to a set point temperature.  A TUS (temperature uniformity survey) is a test or series of tests where calibrated field test instrumentation and sensors are used to measure temperature variation within the qualified furnace […]

Gas vs. Liquid Quenching: A Direct Comparison in Hardenability to Reduce Distortion

Introduction Hardenability is the ability of steel to partially or completely transform from austenite to some fraction of martensite at a given depth below the surface when cooled under a certain condition. The “gold standard” test for all hardenability results has always been the Jominy End Quench Test. The information gained from this test is […]

Deep Cryogenic Treatment

What is deep cryogenic treatment? Deep cryogenic treatment (DCT) of steels and other materials is a distinct process that uses the application of extreme cold applied with distinct time/temperature profiles to modify the performance of materials. This process is also referred to as cryogenic processing, cryogenic tempering, deep cryogenic treatment, deep cryogenic tempering, and deep […]
