Abstract: -
A process of paste boronizing followed by eutecticum treating by high frequency induction heating and
,
the resulting case microstructure were investigated and the principle and mechanism of this process also were
. - ,
discussed The experimental investigation shows that the above mentioned process has a lot of advantages such as
, , ,
shorter treating duration energy saving being easy to manipulate and to achieve mechanization and automatization
, . -
lower cost etc The case of steels boronized and then eutecticum treated by high frequency induction heating
, , ,
consists of boride and eutectic having higher hardnes
