Microstructure and Effective Case Depth of the Vacuum Carburized Steels

진공침탄열처리강의 조직 및 유효경화깊이

This content is a part of the results of the study on the development of the vacuum carburizing technology. In this study the vacuum carburizing furnace being used was the furnace that developed through the joint project between KIMM and Kyung-Pook Heat Treating Co. from June 1988 to Nov. 1990. And the used carburizing gas was the propane gas and the introducing methods of the gas applied two methods such as pulse and constant pressure. By this study we established the basis of the furnace manufacturing technology and of the processing technology in the vacuum carburizing. Above all in this work there are notable meanings in a viewpoint of the foremost research in home. Hereafter, we are going to industrialize the vacuum carburizing technology by improving the results of the present work and by developing the process for the mass production.
