Abstract

In this work, DLC films were produced on AISI 304 stainless steel and AISI 1020 carbon steel substrates. The films were deposited using the pulsed - DC discharge PECVD technique and hexane (C6H14) as a precursor atmosphere. With the aim of  improving  the  adhesion,  an  interlayer  of  amorphous  silicon  was  deposited  using  the  same  deposition  technique  and silane gas (SiH4) as precursor. The mechanical and tribological properties, as well as corrosion resistance, were determined in the DLC films. The experimental results showed that the use of the amorphous silicon interlayer significantly increases the adhesion of the films  on  steel  substrates.  The  high  films  hardness  values  allowed  the  reduction  of  the  friction  coefficient  and  increased wear resistance. The corrosion resistance of the steel surfaces also was improved.
