These new challenges push heat treaters to demand

innovation from equipment suppliers to deliver products

that can perform. In the induction heat treat world, the past

few years have seen advancements in use of multiple fre-

quencies, dual frequencies, computer-aided coil designs,

and FEA analysis to take the “Black Art” out of induction

heat treating. Going forward, a new power supply tech-

nology will provide an even higher level of capability by

enabling independent, stepless, and instant adjustment of

frequency and power during the heat cycle. This technol-

ogy may be the biggest change in the induction heat treat

industry since motor generators and tube oscillators.

State-of-the-art power supply technology allows

the physics and reference depth data of electromagnetic

induction to be coupled with innovative computer pro-

grams to “map out” the exact output necessary for precise

heat treating along vastly changing component geome-

tries. For example, precise heat treating specifications for

gears and half shafts will be able to be programmed, rather

than taking a trial and error approach.

With these new tools being offered to induction heat

treaters, we say to component designers, “Bring it on!”

ars and airplanes. Two dif-

ferent modes of transporta-

tion, two essential products

undergoing radical designchanges

that demand new results from

heat treating providers in terms of

both equipment technology and process capabilities.

Airplanes are undergoing radical redesigns to improve

fuel efficiencies by 15-20% or lengthen range. Whether it

is a new geared turbofan engine or metallic components

throughout the aircraft and landing gear, use of smaller

metal parts and gears demands improved longevity and

lighter weight.

Automobiles are going through exhaustive redesign

every year to meet government fuel targets and custom-

er-driven expectations for higher MPG. Every metallic part

in the engine, drivetrain, frame, and safety and exhaust

systems is being revised to minimize weight and optimize

critical mechanical properties and residual stress dis-

tribution. It often seems that designers do not bother to

consider the practicalities involved in heat treating these

parts—as they add hole after hole, reduce cross sections,

and use “crazy” shapes and exotic alloys.
