Abstract
The influence of temperature of a processable substrate on the strength
characteristics of coverings obtained by the method of ESA is investigated by
using the microstructural microdurometrical analysis. It is established that
a decrease of the temperature of a substrate allows one to increase the
thickness of the strengthened layer by 2–5 times and the microhardness by
1.5–2.5 times depending on a material of electrodes. The increase of
corrosion stability of coverings by more than 1000 times in relation to a
processable material in an unconfigured state is revealed. It is supposed
that this effect can be caused by the formation of a liquid-like structure
of a covering.
