    Abstract

    The properties of hard coatings deposited using CVD-processes are usually excellent. However, high deposition temperatures may negativelly influence the properties of the steel substrates, especially in the case of low alloyed steels. Therefore, a subsequent heat treatment is necessary to restore the properties of steel substrates ready for operation. Bulk hardening and induction surface hardening as two different post-deposition heat treatments are applied on TiN-coated 42CrMo4 (AISI 4140) substrates. The results show great advantages of induction surface hardening because only low distortion appear and the properties of the steel substrates are improved without loosing good coating properties. Thereby, the properties of the steel substrates can be influenced by the parameters of induction heating in a wide range.
