Special Issue Information

Dear Colleagues,

The rising standard of living requires the use of increasingly innovative solutions in the field of biomaterial design. Biotolerance, corrosion resistance, and biological inertness should characterize biomaterials working in a biological environment. To increase the bioactivity and corrosion resistance of materials, protective coatings are usually used, including polymer, ceramic, and metallic coatings. Therefore, novel solutions for obtaining innovative coatings on the surface of biomaterials are constantly sought. This Special Issue will focus on the surface engineering of metallic biomaterials, concentrating on innovative solutions in the field of protective coatings produced using conventional methods and novel techniques. The presented research may concern issues such as surface treatment of biomaterials, mechanisms of layer formation, coatings used to protect against corrosion, and other surface phenomena. Studies that include modification of the surface of biomaterials used for implants and finished products will be accepted.

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 submissions that pass pre-check are 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 2600 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.

The effect of the extrusion process on the microstructure, corrosion, and mechanical properties of Mg–Zn–Ca–Zr alloy has been investigated. Zn and Ca were both in a solid solution and only the Zr-rich phase was observed in the homogenized and extruded alloys. The Zr-rich phase was obviously refined after extrusion. The corrosion rate of the homogenized alloy decreased by about 25% after extrusion. This is because the refined Zr-rich phase was easier to cover with the deposited corrosion products, which reduced the cathodic reaction activity of the Zr-rich phase. The corrosion rate is similar for the alloys extruded at 320 °C and 350 °C since the size and distribution of the Zr-rich phase were not different in the two conditions. The alloy extruded at 320 °C has a smaller grain size and better comprehensive mechanical properties. Full article
