    The properties of hard coatings deposited using CVD-processes are usually excellent. However, high deposition temperatures may negatively influence the properties of 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. Induction surface hardening is applied to TiN-coated 100Cr6 (AISI 52100) and X155CrVMo12-1 (AISI D2) substrates. In comparison to TiN-42CrMo4(AISI 4140)-compounds it is found, that induction heating to higher temperatures is necessary to harden higher alloyed steels but these high temperatures may cause modifications of TiN-coatings. Nevertheless, by optimising the parameters of the induction process there are great advantages of induction surface hardening compared to conventional bulk hardening.
