“…Calcium phosphates (Ca-P) are suitable materials for biomedical applications. Especially hydroxyapatite (Ca 10 (PO 4 ) 6 (OH) 2 , HA) is widely used as a bioactive interface between the bulk metal implant and the surrounding tissue because of their close similarity to the chemical and mineral components of teeth and bones (Shtansky et al 2006).…”

Radio frequency (RF) magnetron sputtering is a versatile deposition technique that can produce thin, uniform, dense calcium phosphate coatings. In this paper, principle and character of magnetron sputtering is introduced, and development of the hydroxyapatite and its composite coatings application is reviewed. In addition, influence of heat treatment on magnetron sputtered coatings is discussed. The heat treated coatings have been shown to exhibit bioactive behaviour both in vivo and in vitro. At last, the future application of the bioactive ceramic coating deposited by magnetron sputtering is mentioned.

Abstract:The relationship between structural, chemical and mechanical properties of nanocrystalline TiC / amorphous C thin films was studied. Thin films were deposited by DC magnetron sputtering on oxidized silicon substrates in argon at 25 C° and 0.25 Pa. The input power of the carbon target was 150 W, the input power of the titanium target was varied between 15 and 50 W. It was found that all thin films consist of a few nanosized columnar TiC crystallites embedded in carbon matrix. The average size of TiC crystallites and the thickness of the carbon matrix have been found to correlate with Ti content. The mechanical properties of the films have been strictly dependent on their structure. The highest values of the nanohardness (~ 66 GPa) and Young's modulus (~ 401 GPa) were observed for the film with the highest TiC content which was prepared at 50 W of Ti target. The relationship between structural, chemical and mechanical properties of nanocrystalline TiC / amorphous C (TiC/a:C) thin films was studied. Thin films were deposited by DC magnetron sputtering on oxidized silicon (Si/SiO 2 ) substrates in argon at 25 C° and 0.25 Pa. The input power of the carbon target was kept at constant value of 150 W while the input power of the titanium target was varied between 15 and 50 W.It was found that all thin films consist of a few nanosized columnar TiC crystallites embedded in carbon matrix. The average size of TiC crystallites and the thickness of the carbon matrix have been found to correlate with Ti content in the films. The mechanical properties of the films have been strictly dependent on their structure. The highest values of the nanohardness (~ 66 GPa) and Young's modulus (~ 401 GPa) were observed for the film with the highest TiC content which was prepared at the largest input power of Ti target.The recommended keywords are: TiC/a:C, magnetron sputtering, structure, mechanical properties, XPS Looking forward your positive answer. Sincerely yours, Nikolett OlahCover Letter SummaryThe nanocomposite structures will be applied as protective materials or hard coating for multifunctional, industrial and engineering applications [6][7][8]. In previous studies only a few preparation methods for TiC films have been investigated in details. One of them, the vacuum deposition provides great flexibility for manipulating material chemistry and structure, resulting in films and coatings with special properties TiC/a:C thin films were deposited by DC magnetron sputtering at 25 °C in argon atmosphere. The films had a thickness of 400 nm and consisted of nanocrystalline TiC and amorphous carbon phases. The average size of TiC crystallites and the thickness of the amorphous carbon matrix strongly depended on deposition parameters, namely on Ti target power. Films deposited at 15 W Ti power consisted of few nanometers small TiC nanocrystallites embedded in a few ten nanometers thick carbon matrix. The increase of Ti content (with increasing Ti power) resulted in larger TiC nanocrystallites and a thinner carbon spacing between t...

“…The compositions of the coatings are modified by changing the power of the titanium source between 5 W and 70 W besides a constant power of the carbon source (150 W) during the depositions. In the literature, the deposition temperatures are mostly around 200°C [20,24,25]. In this work, the used deposition temperature was room temperature mostly for economic reasons and because it may be preferable for easier production in terms of the further applications for industry.…”

a b s t r a c tThe relationship between the structure, elemental composition, mechanical and tribological properties of TiC/amorphous carbon (TiC/a:C) nanocomposite thin films was investigated. TiC/a:C thin film of different compositions were sputtered by DC magnetron sputtering at room temperature. In order to prepare the thin films with various morphology only the sputtering power of Ti source was modified besides constant power of C source. The elemental composition of the deposited films and structural investigations confirmed the inverse changes of the a:C and titanium carbide (TiC) phases. The thickness of the amorphous carbon matrix decreased from 10 nm to 1-2 nm simultaneously with the increasing Ti content from 6 at% to 47 at%. The highest hardness (H) of $ 26 GPa and modulus of elasticity (E) of $ 220 GPa with friction coefficient of 0.268 was observed in case of the film prepared at $ 38 at% Ti content which consisted of 4-10 nm width TiC columns separated by 2-3 nm thin a:C layers. The H3/E2 ratio was $ 0.4 GPa that predicts high resistance to plastic deformation of the TiC based nanocomposites beside excellent wear-resistant properties (H/E ¼0.12).
