AlN thin film was prepared over different metal substrates using DC sputtering at various sputtering parameters. The XRD spectra revealed the presence of mixed (cubic and hexagonal) phases for all samples other than samples prepared at 300W with Ar:N2 gas ratio of 14:6. The intensities of cubic phases observed at copper (Cu) substrates increased drastically with high sputtering power and N2 gas...

Indium titanium zinc oxide (InTiZnO) as the channel layer in thin film transistor (TFT) grown by RF sputtering system is proposed in this work. Optical and electrical properties were investigated. By changing the oxygen flow ratio, we can suppress excess and undesirable oxygen-related defects to some extent, making it possible to fabricate the optimized device. XPS patterns for O 1s of InTiZnO ...

Modern applications of refractory ceramic thin films, predominantly as wear-protective coatings on cutting tools and on components utilized in automotive engines, require a combination of excellent mechanical properties, thermal stability and oxidation resistance. Conventional design approaches for transition metal nitride coatings with improved thermal and chemical stability are based on alloy...

A dry bracelet electrode for electrocardiographic (ECG) signal monitoring was developed and successfully tested in human volunteers. The new electrode dispenses with the usual gel application and the previous skin preparation to monitor the signal. It was fabricated from a polyethylene tereftalate (PET) polymer sheet that was coated with a thin conductive titanium nitride (TiN) layer. As the di...

This study investigated the mechanical properties and residual stress of high-power impulse magnetron sputtering (HiPIMS) titanium nitride (TiN) thin film capping on cold spray (Ti) coating. TiN/Ti duplex coating was deposited Ti substrate, prepared in three cases with different numbers layers. The determined Young’s modulus, hardness, roughness TiN coatings by nano-indentation AFM. measurement...

The production of thin mesoporous silica films with small (∼2-3 nm) pores oriented perpendicular to a titanium nitride growth surface is demonstrated using two methods. These are the growth from a Stöber silica solution with surfactant ordering at the surface of the electrode, and electrochemically assisted growth from an acidic sol achieved by polarisation of the electrode surface. The thickne...

The problems associated with Stainless Steel 316 L (SS L) orthopedic implants, when implanted in the human body, are infection, local inflammation, and possibility of bacterial growth. In this study, SS was coated copper-doped Titanium Nitride (Ti–Cu–N) using DC Sputtering technique. This Ti–Cu–N film improved antibacterial performance mechanical properties L. films were deposited reactive sput...
