The process of boronizing and borochromizing in a vibrofluidized bed is con
sidered. It is shown that use of a vibrofluidizcd bed makes it possible to
intensify considerably the processes of surface impregnation. Boronizing an
d borochromizing of high-alloy martensite and maraging steels are studied w
ith the aim of increasing the wear resistance of the surface and obtaining
a heal-resistant matrix.
