The Spallation Neutron Source (SNS) ring is designed to accumulate, via H injection, 1.6x10 protons per pulse at 60 Hz and 1 GeV energy [1]. At such beam intensity, electron cloud is expected to be one of the intensity-limiting mechanisms that will complicate ring operation. This paper presents the design of the ring vacuum system and the mitigation strategy adopted to suppress the electron clo...

We report a study on the biocompatibility vs. thickness in the case of titanium nitride (TiN) films synthesized on 410 medical grade stainless steel substrates by pulsed laser deposition. The films were grown in a nitrogen atmosphere, and their in vitro cytotoxicity was assessed according to ISO 10993-5 [1]. Extensive physical-chemical analyses have been carried out on the deposited structures ...

Titanium Nitride (TiN) is a wear resistant and complementary metal oxide silicon (CMOS) compatible material that is increasingly being investigated for MEMS applications. Incorporating any new material into a MEMS device requires the development of a processing strategy. This paper discusses a wet-etching strategy for patterning and releasing TiN features on Cr sacrificial layers. Filtered arc ...

Abstract This study compares two tools, HSS M42 and TiN Coated twist drill bits, in order to determine which tool has the better material removal rate (MRR). Drill bits were of high speed steel (HSS M42) use Novel coating Titanium Nitride on this study. The machining is done a experimental specimen made aluminium alloy AA6063. both tools measured CNC drilling sets 20 specimens each. Spindle spe...

In this work, a nanolayer of titanium nitride which produced by the magnetron sputtering system is synthesized. Moreover the effect of plasma parameters on the electron temperature is studied. Electron temperature has a significant effect on the plasma coating system properties. The results show that, increasing the working pressure and nitrogen ratio in the system causes decreasing electron te...

titanium nitride-copper (tin-cu) nanocomposite films were deposited onto stainless steel substrate using hollow cathode discharge ion plating technique. the influence of cu content in the range of 2-7 at.% on the microstructure, morphology and mechanical properties of deposited films were investigated. structural properties of the films were studied by x-ray diffraction pattern. topography of t...

Thin film coatings are used to reduce the generation of secondary electrons at the ends of the Advanced Photon Source (APS) rf cavity tuners because these electrons result in increased temperatures on the tuner. To improve the film properties over the existing evaporated titanium film, a magnetron-sputtered film of titanium nitride has been developed that is both harder and adheres more strongl...

Aqueous zinc-ion batteries (AZIBs) have become attractive energy storage devices, owing to their high density, low cost, and environmental friendliness. However, the stability of zinc-metal anode has been retarded by dendrites side reactions during cycling process, limiting its practical application in secondary batteries. In this work, porous titanium nitride (TiN) nanosheets with a surface ar...

Hierarchical nanotubular TiN was prepared by magnesiothermic reduction of titania replicas of a cellulose substance (filter paper), which possessed high surface area (31.4 m(2) g(-1)), and was demonstrated to be a promising electrode material due to its electrochemical performances.

This research work presents the results of an experimental investigation of cryogenically treated, coated and uncoated tungsten carbide cutting tool inserts in turning of AISI 1040 steel. Three different tungsten carbide inserts coated with aluminum chromium nitride (AlCrN), titanium nitride (TiN) and uncoated WC were taken and treated cryogenically. Experiments were performed to evaluate the c...
