| Summary: | The numerical results of prognostication of the hardness and thickness of surface layer of
the steel (35ХГСА) holder in results of the hardening in water solution of polymer Na–KMC and in
machine oil I-20 at 20 ºС are presented. It is establish, that in polymer medium the cooling rate of
the steel holder to temperature of start of the martensite transformation is in 2–3 times greater than
in machine oil. But if cooling duration to temperature of termination of the martensite transformation
is smaller than 70 c, than results of the hardening in polymer medium and in machine oil are
practically identical. It is shown that one way to influence on results of the hardening may be the
choice of the cooling duration in the air after induction heating. |
