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...

This paper is a review on the status of hard coating of various physical vapour deposition (PVD) techniques and compare their properties. The use of hard and wear resistant PVD coatings on cutting tools is now widespread in global manufacturing for reducing production cost and improving productivity, all of which are essential if industry is to remain economically competitive. The review includ...

Mono- and multilayer coatings can be suitable alternatives to traditional bulk materials due their favorable mechanical properties. Thanks the ever-evolving coating technology process, there are a wide variety of types today, such as soft, hard, or super-hard that made with single coatings.
 Adhesion damage is especially important for coated tools, where reduce tool life result in deterior...

Much of the information we are seeing at this symposium revolves around the utility of Zn rich coatings. Marine Environmental Research (MER) has been examining these coatings as the material component in a surface protective system applicable to both marine and land based needs. The nonmaterial component of this system is electrical. The way these two components interact and the surprising resu...

Hard coatings such as titanium nitride (TiN) and chromium nitride (CrN) are widely used in cutting and forming tools against wear and corrosion. In the present study, hard coating films were deposited onto AISI 1070 steels by a cathodic arc evaporation plating (CAVP) technique. These samples were subjected to wear in a conventional lathe for investigating the tribological behaviour of coating s...

BACKGROUND Biofilm formation and deep infection of endoprostheses is a recurrent complication in implant surgery. Post-operative infections may be overcome by adjusting antimicrobial properties of the implant surface prior to implantation. In this work we described the development of an antimicrobial titanium/silver hard coating via the physical vapor deposition (PVD) process. METHODS Coating...
