Abstract

In the paper, it is stated that the HfC x N 1-x coating was deposited by magnetron sputtering on the AISI 316L substrate materials at various substrate temperatures ( T s ). The results of XRD and TEM indicated that the HfC x N 1-x coatings were almost amorphous when the T s were below 400 °C, whereas the nanostructured Hf 2 CN was formed at the T s of 400 °C. The Hf 2 CN nanocrystalline formation resulted in a significant improvement in the mechanical properties of HfC x N 1-x coatings. The electrochemical tests demonstrated that the stable HfC x N 1-x coatings improved the corrosion resistance of the AISI 316L. The platelet adhesion tests and hemolysis ratio tests indicated that the HfC x N 1-x coatings presented an improved hemocompatibility when the T s varied from 25 °C to temperatures exceeding 300 °C, which might have occurred due to the surface topography, the interfacial tension and the γ s d / γ s p ratio.
