Subsequent EBH improves the load-supporting capacity of PVD-coated steels. The influence of the chemical composition and layer thickness of Ti1−xAlxN coatings on the results of EBH was investigated. Increasing Al contents, along with increasing layer thicknesses improve the heat input during EBH. It is possible to harden the steel through the PVD layer without negative influences on the metastable coatings.
