Titanium alloys, particularly Ti6Al4V, are widely used in biomedical applications due to their excellent mechanical properties and inherent biocompatibility. However, enhancing surface characteristics, such as biocompatibility corrosion resistance, remains a key challenge for long-term use medical implants. In this study, we investigate the effects of rhenium–carbon coatings deposited on Ti6Al4V substrates via magnetron sputtering, incorporating molybdenum anchoring layer. X-ray diffraction (XRD) energy dispersive spectroscopy (EDS) analyses confirmed formation rhenium carbides, elemental rhenium, oxides within coatings. Despite these successful depositions, scanning electron microscopy (SEM) revealed significant delamination poor adhesion substrates. Corrosion evaluated through potentiodynamic polarization tests, showed an increase current densities more negative potentials, indicating detrimental effect substrate’s resistance. Biocompatibility assessments using PK15 cells demonstrated marked decrease cell viability metabolic activity, samples with higher roughness. These findings underscore critical need optimization preparation deposition processes improve both Future research should aim refine coating technique enhance adhesion, explore mechanisms cytotoxicity related roughness, expand studies across different lines biological environments.

Abstract Smart biomaterials that can self‐adapt or respond to microenvironmental factors external signals hold excellent potential for a variety of biomedical applications, from biosensing, drug delivery, and cell therapy tissue engineering. The complexity smart biomaterials, including the rational design their structure composition, accurate analysis prediction properties, automatic scale‐up synthesis remains critical challenge but be addressed by recent rise artificial intelligence (AI). To bridge literature gap, current mini‐review will introduce background why marrying AI with is essential how biomaterial scientists integrate machine learning (ML) discovery, design, analysis, biomaterials. For this purpose, basic principles ML first introduced so use as tool research. Next, representative examples using high throughput screen establish big data structure‐function relationship responding both chemical, biological, physical signals. Most importantly, applications AI‐designed AI‐discovered overviewed, focus on field Lastly, new directions, such robot‐chemists‐assisted fabrication highlighted. Taken together, engaging most updates in material science, we expect observe continuous growth science benefit clinical translation treating diseases.
