Conclusions

  1. 1.

    When steel components are subjected to boriding in new salt melts, the required thickness of the boride layer is attained after a short time interval with an economic consumption of boron-containing components and activator. Use of these melts ensures the high in-service stability of a threading tool.

     
  2. 2.

    The accelerated method using an MT-40NTs electronic instrument and thin strip specimens formed from steel 50KhFA is recommended for monitoring the boriding activity of the salt melts.

     
  3. 3.

    The thickness of the boride layer on components can be determined by the computational method that we have proposed, using control specimens without destroying the components.
