The amorphous hydrogenated carbon coatings (a-C:H) deposited by plasmaassisted chemical vapour deposition (PACVD), and tetrahedral amorphous carbon coatings (ta-C) deposited by pulsed vacuum arc discharge were evaluated by scratch adhesion testing, load-carrying capacity testing and tribological testing in unlubricated and lubricated sliding conditions. The wear surfaces of the coatings and cou...

Freshly coated aluminum mirrors have excellent reflectivity at far ultraviolet wavelengths. However, reflectivity rapidly degrades when the mirror surfaces are exposed to atmosphere. In order to avoid this problem, freshly coated aluminum surface can be protected by over-coating of a removable volatile protecting coating. This protecting coating can be re-evaporated by controlled heating or by ...

We report on the fabrication and characterization of thick UV-patternable hybrid sol-gel films by spin coating using a modified sol-gel process. Thick coating of 25 microns with crack-free surface can be produced by one spin coating step. Thick layers of more than 100 μm can be obtained with a multi-coating process. Characterization using different techniques including optical microscope and at...

Coating of particulate solids by a thin film layer is of interest in many industrial applications such as seed and tablet coating. In seed processing, seeds are commonly coated with a protective coating layer consisting of fertilisers and crop protection products. Rotary drum batch coaters are typically used for this purpose. The coater consists of a cylindrical vessel with a rotating spray dis...

Standing wave field distributions in three classic types of graded-index antireflection coatings are studied. These graded-index antireflection coatings are designed at wavelengths from 200 nm to 1200 nm, which is the working wavelength range of high energy laser system for inertial-fusion research. The standing wave field distributions in these coatings are obtained by the numerical calculatio...

OBJECTIVE To develop differential criteria on the tongue coating thickness (TCT), and especially propose the standard for judgment on thin and thick coating in tongue diagnosis. METHODS Sixty oriental medical doctors evaluated the TCT (none, thin, and thick coating) in 50 realistic tongue photographs revealing from tip-to-root. The photographs were obtained with a digital tongue imaging syste...

Ultra-thin diamond-like carbon (DLC) coatings are used in hard disk drives to protect the intricate magnetic structures from wear and corrosion. The coating on the recording head consists of a hard DLC layer and a silicon (Si) layer that improves adhesion between the DLC layer and the substrate. Damage to this protective coating can expose the magnetic structures to corrosion and compromise the...

AIM To evaluate the effects of two different resin coating materials on the clinical performance of a conventional glass ionomer sealant. MATERIALS AND METHODS Permanent first mandibular molars of 60 children aged 6-9 years were sealed with Fuji VII. In each child, G-Coat Plus coating agent was applied to molars on one side and Heliobond coating agent to molars on the opposite side of the mou...

A β-Ta nanocrystalline coating was engineered onto a Ti-6Al-4V substrate using a double cathode glow discharge technique to improve the corrosion resistance and bioactivity of this biomedical alloy. The new coating has a thickness of ~40 μm and exhibits a compact and homogeneous structure composed of equiaxed β-Ta grains with an average grain size of ~22 nm, which is well adhered on the substra...
