Conclusions
-
1.
All the alloyed elements decrease the rate of increase of the thickness of the borided layer.
-
2.
Elements which increase the binding strength in the austenite lattice have the most important decelerating effect on the diffusion of boron. They decrease the diffusion rate of carbon and deform the lattice of the metalsolvent (γ-Fe) very little.
-
3.
The elements which form stable borides increase the concentration of FeB in the layer and decrease the amount of the second boride (Fe2B).
-
4.
With increasing degrees of alloying of the steel and with increasing saturation temperatures the structure of the boride needles becomes more complex.
