Abstract
Conventional surface heat-treatment processes are carried out at high temperature, hence both the equipment and the operation costs are high. However, heat treatment is an important linkage-industry to support other manufacturing industries. This paper introduces an advance surface heat- treatment technique that can be operated at room temperature, with low cost and easy control, which hence improves its competitiveness. This is an electrolytic heat-treatment method in aqueous solution, especially using pulse current as a new aspect in the area of surface-hardening technologies. After a feasibility study, a special high-power pulse rectifier and an electrolyte bath system were designed and fabricated to investigate this new technology of electrolytic heat-treatment The performance of the electrolytic heat-treatment process has been evaluated. Comparing with direct current, different heating rates under pulse current are easily secured by varying the pulse period, the ON:OFF ratio and the voltage. More controllable and ideal operating conditions are expected using electrolytic heat-treatment in aqueous solution to surface harden medium-carbon steel.
