The influence of the laser-processing parameters on the adhesion strength
of the Fe-Cr-B-Si-system coating has been investigated. The characteristics
of a change in the adhesion strength of coatings, as well as in the amounts
of iron borides as functions of the velocity of travel, diameter of a laser
beam, and coefficient of overdropping have been studied.
