The coatings based on carbon nanotubes (CNTs) are increasingly developed for their applications, among others, in medicine, in particular for implants in implantology, cardiology, and neurology. The present review paper aims at a detailed demonstration of diferent preparation methods for such coatings, their performance, and relationships between deposition parameters and microstructure and material, mechanical, physical, chemical, and biological properties. The thermal and electrostatic spraying, electrophoretic and electrocathodic deposition, and laser methods are presented. Characterization of microstructure of coatings, topography, morphology, adhesion of CNTs to a substrate, mechanical behavior, corrosion resistance, wettability, cytotoxicity, bioactivity, and antibacterial protection are reviewed for diferent deposition methods and parameters. The state-of-the-art in the feld of carbon nanotubes shows a considerable number of research performed on CNTs coatings. The diferent forms of CNTs, deposition methods, parameters, and substrates were applied as process variables. The microstructures and surface homogeneity, chemical and phase compositions, mechanical properties at the micro- and nanoscale such as coating Young`s modulus and hardness, interface adhesion strength and delaminating force, open corrosion potential and corrosion current density, contact angle in wettability assessment, and bioactivity, cytotoxicity, and antibacterial efciency among biological properties were determined. The summary of so far achievements, strengths and weaknesses, and important future research necessary for clarifcation of some weak points, development of non-toxic, mechanically and chemically resistant, bioactive, and antibacterial multicomponent coatings based on functionalized CNTs are proposed.
