滲炭剤としての鋸屑の研究（第2報）

Instead of the sawdusts alone, the generated charring gases of the sawdusts mixed with 5%,10% and 20% of lime at the charring temperatures of 700°, 800° and 900° respectively, and also their carburizing characters at 925° were studied. The experimental results show that there is generated a much greater amount of CO in charring gases compared with tha t of sawdusts only. So the steel specimens imbedded in them are more powerfully carburized by useing lime mixed sawdusts.Moreover, the influence of coke mixed with the sawdusts on the carburizing action at 925°, was studied and it was found that there is a nullifying tendency of the carburizing power of sawdusts by adding coke powders.
