Від 2002 року кафедра має назву "Фізика металів і напівпровідників", попередня назва – кафедра металофізики.

Кафедра металофізики організована в 1930 році у складі фізико-механічного факультету ХММІ. Деканом факультету був у ті роки видатний вчений-фізик, академік Іван Васильович Обреїмов.

Кафедра входить до складу Навчально-наукового інституту комп'ютерного моделювання, прикладної фізики та математики Національного технічного університету "Харківський політехнічний інститут". За час існування кафедрою підготовлено близько 3000 інженерів, у тому числі і для зарубіжних країн.

У складі науково-педагогічного колективу кафедри працюють: 3 доктора та 2 кандидата фізико-математичних наук; 3 співробітника мають звання професора.

    Investigation of diamond biocompatible coatings for medical implants
    (Харківський національний університет ім. В. Н. Каразіна, 2015) Starikov, V. V.; Starikova, S. L.
    Despite the advantages of diamond-like carbon fi lms that are used as wear-resistant coatings for implants, they may have a number of disadvantages such as the high level of internal tension, low adhesive durability and high sensitivity to environment conditions. These problems can be overcome by application of the new carbon nanocomposite coatings that can be deposited from C60 ionic beam. It was found that the proposed diamond-like nanocomposite coatings increase implant material resistance to electrochemical corrosion processes due to shift of its electrode potential to area of positive values, and also promote a complex of reparative and adaptation and compensatory reorganizations that will allow to accelerate processes of healing and postoperative adaptation of organism in zone of implant inputting.

    Diamond biocompatible coatings for medical implants
    (Collegium Basilea & AMSI, 2016) Starikov, V. V.; Starikova, S. L.; Mamalis, A. G.; Lavrynenko, S. N.
    New carbon (diamond-like) nanocomposite coatings deposited from a C60 ionic beam can be used as a wear-resistant protective coating for implants. It was found that these coatings enhance resistance to тelectrochemical corrosion processes due to a shift of the material’s electrode potential to a zone of positive values. They also promote a complex of reparative, adaptative and compensatory reorganization that accelerates the healing processes in the vicinity of the implant.

    Highly wear-resistant and biocompatible carbon nanocomposite coatings for dental implants
    (Elsevier, 2016) Penkov, Oleksiy V.; Pukha, Vladimir E.; Starikova, Svetlana L.; Khadem, Mahdi; Starikov, Vadym V.; Maleev, Maxim V.; Kim, Dae-Eun
    Diamond-like carbon coatings are increasingly used as wear-protective coatings for dental implants, artificial joints, etc. Despite their advantages, they may have several weak points such as high internal stress, poor adhesive properties or high sensitivity to ambient conditions. These weak points could be overcome in the case of a new carbon nanocomposite coating (CNC) deposited by using a C60 ion beam on a Co/Cr alloy. The structure of the coatings was investigated by Raman and XPS spectroscopy. The wear resistance was assessed by using a reciprocating tribotester under the loads up to 0.4 N in both dry and wet sliding conditions. Biocompatibility of the dental implants was tested in vivo on rabbits. Biocompatibility, bioactivity and mechanical durability of the CNC deposited on a Co/Cr alloy were investigated and compared with those of bulk Co/Cr and Ti alloys. The wear resistance of the CNC was found to be 250e650 fold higher compared to the Co/Cr and Ti alloys. Also, the CNC demonstrated much better biological properties with respect to formation of new tissues and absence of negative morphological parameters such as necrosis and demineralization. Development of the CNC is expected to aid in significant improvement of lifetime and quality of implants for dental applications.
