Abstract

A study has been made on the adhesion of the new composite ceramic AlN - Ti(Zr)B2 -Ti(Zr)Si2 with steel 45 and alloy AL9 in relation to the mass-transfer kinetics in spark working. There is a three-stage mass-transfer mechanism. The materials in the electrode and the substrate affect the electrical erosion of the electrode.
