Comparative Studies of the Physical, Mechanical and Chemical Properties of Hybrid Coatings for Medical Implants

In the work the physical, mechanical and chemical properties of oxide and calcium-phosphate coatings formed by the microarc oxidation and radio-frequency magnetron sputtering methods, or their combination were studied. It is shown that combining the advantages of various technologies enables one to obtain a wide range of hybrid coatings used for various strategies of osteosynthesis. The calcium phosphate coatings obtained by the radio-frequency magnetron sputtering methods were chosen as coatings on cortical screws. The hybrid coatings obtained by a combination of microarc oxidation method and radio-frequency magnetron sputtering method were recommended for intramedullary implants. For extramedullary implants, the most optimal coatings are the coatings formed by radio-frequency magnetron sputtering with an intermediate TiO[2] sublayer
