Titanium and its alloys are important modern materials used for a variety of applications, in aeronautics, the automotive industry, extreme sports, and biomedical engineering. Commercially pure grades of titanium are commonly used in dentistry, after specific anodic surface treatments. As a transition metal, titanium serves to produce two-, three-, and four-component alloys, with favorable increased strengths and corrosion resistance. Plasma electrolytic oxidation (PEO) processes are developed to improve the surface of titanium alloys which serve for the production of joint endoprosthetics, elements for joining bone fractions, components of heart valves and artificial hearts in cardiac surgery and interventional cardiology, and for medical instrumentation.
Currently used electrochemical treatments such as PEO, known also as micro-arc oxidation (MAO) processes, serve to modify titanium and its alloys. A variety of surface properties are achieved thanks to the introduction of expected elements and compounds into the fabricated coatings of mono- or multi-layer structure. Porous coatings formed on the metal surface are fabricated for their biocompatibility and non-toxicity, with bactericidal properties, and may exhibit hydrophilic or hydrophobic properties.
This Special Issue is devoted to displaying the recent advances and achievements in the field. Specifically, modern electrochemical treatment methods to control the composition of the surface layer, its structure, and its properties on request are a focus.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Materials is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2000 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
