patite and SiO2 nanocoatings on titanium are discussed.

Constant progress in engineering in the area of advanced structures and technologies for aerospace and power industry, medicine, automatics and mechatronics, manufacturing of control and measurement equipment, is driven to a large extent by development and appli‐ cation of new or modified functional materials. It includes titanium and its alloys, although initially they were intended mainly for use as a structural material for load, carrying air‐

Titanium enables implementation of new solutions in structures and technologies due to its unique combination of physical, chemical and mechanical properties. First of all, it has a low density, high strength properties and good corrosion resistance in many chemical environ‐ ments. Titanium is also characterized by low thermal conductivity and thermal expansion,

During the last decades, extensive research efforts have been concentrated on the evolution and control of the titanium alloys microstructure through adjustment of the processing pa‐

Simultaneously, there was significant development of the methods for obtaining better properties of the surface layer of the elements made of titanium and its alloys. The aim was to increase hardness, prevent seizure in case of machine kinematic pairs and also to increase biocompatibility and corrosion resistance of medical implants in human body. The results of

The book contains six chapters and covers topics dealing with biomedical applications of titanium alloys, surface treatment, relationships between microstructure and mechanical and technological properties, and the effect of radiation on the structure of the titanium al‐

In the first chapter application of titanium alloys in orthopaedics is explored with emphasis on strategies for enhancing their bioactivity and promoting osseointegration of the implants. The second chapter deals with techniques for surface modification of medical implants lead‐ ing to their prolonged use. The results of the studies on the influence of sputtered hydroxya‐

In the third chapter the processes of diffusive saturation of titanium by interstitial elements are modeled taking into account interaction of titanium with nitrogen and oxygen. The po‐ tentials of the model for estimating the effects of thermo-chemical treatment are discussed.
