On the distribution of a saturating element in the zone of laser siliconizing of steels

The distribution of a saturating element in the zone of laser siliconizing of steels has been investigated by the method of electron microprobe analysis. It has been established that the silicon concentration reaches 17–20 at. % in the upper part of the siliconized layer and decreases to 3–5 at. % with going to the boundary of partial melting. The role of the crystallization processes in the formation of the concentration field of the zone of laser chemical thermal treatment has been discussed.
