Platelet adhesion on hard material coatings and bonding agents for ventricular assist devices in a flow chamber

< 0.05). Cr (3.6) exhibited significantly more platelets than CrN with a medium effect compared to CrN, Ti (0.2), TiN (0.3), and SiDLC, and a weak effect compared to TiN_D (0.4) and Alu. No significant differences were observed among HMCs, Ti, and CrN. This study highlights Cr's elevated thrombogenicity, whereas the other surfaces (except Alu) showed hemocompatibility comparable to Ti, supporting their use in VADs.
