Title
Study on the Effect of Ultrasonics on Boronizing of Steel
김재곤J . K . Kim, 천성순S . S . Chun
Abstract
The effect of ultrasonics on the mechanism and mechanical properties of liquid and electro-boronizing has been investigated. Surface hardness and wear resistance were increased by ultrasonics in electro-boronizing and liquid boronizing, the effect of ultrasonic was more effective at lower temperature. The depth of boride layer was increased by ultrasonics, especially, in the case of electro-boronizing, it was found that the case with treating temperature 850℃ and current density 0.5A/㎠ was effective. The increased rate of boronizing is supposed by the following facts; promotion of mixing of salts, activation of surface, acceleration of chemical reaction by degassing effect.
