Conclusions
-
1.
The chemical composition of carbon steels and low alloyed steels has no significant effect on the diffusion rate of boron.
-
2.
The borating rate decreases with increasing amounts of carbon in the steel and becomes higher than the ordinary rate only after a prolonged borating time.
-
3.
The amounts of carbon and alloyed elements in the steel have no effect on the main phase composition of the borated layer but change its structure and the quantitative ratio between the phases in the layer.
-
4.
The migration of carbon from the borted layer into the sample changes the chemical composition and the properties of the transition zone and equalizes the conditions for the diffusion of boron in steels containing different amounts of carbon.
