Spark Hardening of Pipe-Bending Mandrels

  • Published:
Metal Science and Heat Treatment Aims and scope

Abstract

The effect of coatings on tungsten and tungsten-free substrates deposited by spark hardening on pipe-bending mandrels on their adhesion properties in operation is investigated. It is shown that the presence of such coatings on a mandrel decreases the number of regions of metal stuck to the latter.
