Abstract
DLC coatings are of great industrial interest due to the need to obtain materials with very specific properties. This material provides a remarkable combination of high hardness and low coefficient of friction, which is why its presence in the industry is booming.
This work takes advantage of the properties offered by DLC to generate nanocomposite coatings that, in turn, can be doped with copper to promote the biocidal character of the layer. The deposition of the proposed coatings is carried out using DCMS and the innovative HiPIMS technique. The samples are subjected to different tests to compare the mechanical and structural properties.
The proposals shown in this work are divided into two groups. The first group includes DLCs that have been deposited by DCMS or HiPIMS, while the second group includes carbon-based nanocomposites doped or not doped with copper. This classification will be reflected in the presentation of results. Likewise, 3 substrates are chosen for each proposal: cold work steel (12379), stainless steel (SS316), and monocrystalline silicon (Si).
Successfully achieving a biocidal coating with adequate mechanical properties can be of great industrial interest for various sectors.
