we studied the boron on steel by the electrolysis A fused borax, using steel as cathode on which boron waa deposited.
The results of experiments were as follows 1) The cementation occumed at so low temperature as 800° and above 900° it increased expnnemiall with tomperature.
2) When 0.15%, steel was cemented for example at 900° and 10 Amp/dm2 for 2 hrs, the thickness of the cemented layer was about 0.1mm and the hardness of the layer was so high as approximately 1200 Vickers hardness.
3) W, Mo or V etc. added to steel retarded the cementation of boron on iron, and C, Ti, Si, W etc. increased the hardness of the cemented layer.
