The article reports on flexible hard nanocomposite coatings prepared by magnetron sputtering.
This article reports on interrelationships between x-ray structure, mechanical properties, coefficient of friction μ, and wear k ∼3000 m thick nc-TiC/a-C nanocomposite films sputtered using unbalanced magnetron from a composed C/Ti target (∅=100 mm); here nc denotes the nanocrystalline amorphous phase, respectively. It is shown that (1) μ film strongly depend not only its hardness H but also effective Young’s modulus E∗=E/(1−ν2); ν Poisson s ratio, (2) with C/Ti>1.5 ratio H3/E∗2...
Cross-sectional transmission electron microscopy (XTEM) has been used to investigate the effects of variations in low-energy ion irradiation flux during growth reactively sputter-deposited TiN. The films were deposited on steel substrates with a negative bias 100 V at 350 °C mixed Ar–N2 discharges pressure 5 Pa (37 mTorr). ion-to-Ti arrival rate ratio Jion /JTi substrate was varied between 0.3 and 7.1 through use variable external magnetic field. Films grown ≲2 had columnar morphology highly...
Abstract Fundamental aspects of magnetron operation in two types practically interesting discharges, i.e. highpower unipolar pulsed dc discharges for ionized high‐rate sputtering and asymmetric bipolar reactive sputtering, were investigated on the basis time‐resolved plasma diagnostics. We present results obtained using optical emission spectroscopy time‐ energy‐resolved mass high‐power at a repetition frequency 1 kHz, an argon pressure Pa average target power loading pulse up to 500 W/cm 2...
Hydrophobic materials capable of withstanding harsh conditions are required for various applications. Here, we show that oxides and nitrides low‐electronegativity metals hydrophobic hard ceramics. We attribute their hydrophobicity to low Lewis acidity the cations implying a ability on surface form coordinate bonds with water oxygen anions. Furthermore, observe systematically stronger behavior compared corresponding oxides, which nitrogen being poorer base than due reduced number lone pairs...
