Annotation A practical selection guide to help engineers and technicians choose the mot efficient surface hardening techniques that offer consistent and repeatable results. Emphasis is placed on characteristics such as processing temperature, case/coating thickness, bond strength, and hardness level obtained. The advantages and limitations of the various thermochemical, thermal and coating/surface modification technologies are comparedInduction Heat-Treating Equipment An induction heat treating system typically consists of a power supply, a workstation, an inductor (heating) coil, ... Regardless of the electronic technology, the power supplies perform a common function. Figure 6shows a block diagram of modern high-frequency power supplies performing line frequency conversion into high frequency. ... field-effect transistors (MOS FETs), to produce dc pulses that are then made sinusoidal to form high-frequency ac.
