Abstract
The objective of the present work was to study the modification of the microstructure of
hot-work tool steels X40CrMoV5-1 and X38CrMoV5-3 during the surface modifying by means of
laser technology. This treatment aims to harden and alloy the steel surface which had been previously
coated with tungsten carbide (WC) and were introduced using the rotor conveyer to improve the
properties of the surface layer. The fine grained, dendritic structure occurs in the remelted and alloyed
zone with the crystallization direction connected with the dynamical heat abstraction from the laser
beam influenced zone. The fine grained martensite structure is responsible for the hardness increase
of the alloyed layer.
