1. Designing and fabrication of a low-cost dip-coater for rapid production of uniform thin films
In this work, a self-made dip-coater equipment was developed for the fabrication of thin films. The assembly of the apparatus was carried out using simple mechanical and electronic pieces, recycle parts, and spending an inexpensive budget suitably. The production, software design, and features of the device were focused on the sol-gel dip-coating method, whi

2. COMPARATIVE STUDY OF TiO2 AND ZnO APPLICATION IN HYBRID SOLAR CELLS USING COPOLYMER P3OT/P3MT
Hybrid inorganic-organic solar cells are an attractive alternative energy source because of their low-cost production and ability to make use of a large amount of solar radiation available. This work aims to evaluate different solar cells composed of TiO2 and ZnO with P3OT/P3MT copolymer. Layers of semiconductor oxides were deposited on transparent fluorine-

3. Investigation on the Wear Properties of Ti/TiC/TiN Composite Coatings Prepared by Powder Cored Wires Through TIG Method at Nitrogen Atmosphere on Titanium Substrate
In this present study, Tungsten Inert Gas (TIG) welding and powder filled cored wires with nitrogen shielding gas were utilized to produce TiC and TiN surface composite coatings on the titanium (Ti) sheet substrate. The TIG procedure was done at same welding parameters for all of prepared samples. Phase analysis and microstructures were done by X-ray Diffrac

4. An Investigation on Surface Roughness and Tool Wear in Turning Operation of Inconel 718
ABSTRACT: This paper investigates the influences of three different input parameters, such as feed rate, insert nose radius, and insert coating methods, in the turning operation of Inconel 718. The coating methods were selected as medium temperature chemical vapor deposition (MT-CVD) and physical vapor deposition (PVD) and in addition to coating methods, the

5. Fatiga de contacto por rodadura en acero SAE 1050 recubierto con TiN, posteriormente templado
ABSTRACT The use of ceramic coatings of the nitride, carbide, or diamond type on steel substrates promotes the improvement of tribology properties. Nevertheless, high hardness gradients and adhesion problems may deteriorate the performance of these coatings when subjected to Rolling Contact Fatigue (RCF). Some studies on steels with ceramic coatings were car

6. ITO Obtained by Spray Pyrolysis and Coating on Glass Substrate
Conductive thin films have various applications in different technological fields. Indium tin oxide (ITO) is a mixed oxide. In the film form, ITO has been widely employed as electrode in many optoelectronic devices. Methods like thermal evaporation, sputtering, chemical vapor deposition (CVD), electron beam, spray coating, and sol-gel synthesis give ITO thin

7. The correlation between tribological properties of nanostructure TiN coatings and deposition process parameters in PACVD system
ABSTRACT Titanium base coatings are being used extensively for improving wear characteristics at the surface of different parts. Titanium nitride was deposited by Plasma Assisted Chemical Vapor Deposition (PACVD) techniques with purpose improve interface with substrate, as this can increase wearing of the entire part in spite of desirable wear behavior of Ti

8. Investigation of borided layers contribution on the wear resistance and adhesion of TiN coatings
ABSTRACT The purpose of the investigation was to examine the possibility of improving tool life by reducing the wear effect and improving the adhesion of a thin film through a compound configuration that consists in boriding and PVD deposition. Single layer coatings of TiN were deposited by PVD (cathodic arc) on quenched and tempered and on borided powder me

9. Corrosion Behavior Analysis of Plasma-assited PVD Coated Ti-6Al-4V alloy in 2 M NaOH Solution
The work aims the study of the corrosion behavior of nitride plasma-assisted PVD coated Ti-6Al-4V alloy in 2 M NaOH at 25 and 60°C, using open-circuit potential (OCP) versus time measurements, potentiodynamic polarization and electrochemical impedance spectroscopy (EIS). The uncoated Ti-6Al-4V alloy showed a passive behavior. The TiN and TiAlN/TiAlCrN coate

10. Methods of data analysis for the ball cratering test on TiN and DLC coated steel
Titanium nitride (TiN) coatings are widely used in machining because of its mechanical characteristics which modify the surface of the substrate increasing the capacity of load support and reduction of friction, while a coating as diamond-like carbon (DLC), which also has interesting mechanical properties, needs better attention. In this sense, the developme

11. Effect of Low Temperature Nitriding of 100Cr6 Substrates on TiN Coatings Deposited by IBAD
In this paper we studied the influence of pre-treating the surface of 100Cr6 steel by ion beam nitriding at low temperature (380°C) on the surface topography and wear resistance of thin TiN coatings deposited by reactive ion beam assisted deposition. The specimens were characterized by grazing incidence X-ray diffraction, scanning electron microscopy and at

12. Photo-Induced conductivity of heterojunction GaAs/Rare-Earth doped SnO2
Rare-earth doped (Eu3+ or Ce3+) thin layers of tin dioxide (SnO2) are deposited by the sol-gel-dip-coating technique, along with gallium arsenide (GaAs) films, deposited by the resistive evaporation technique. The as-built heterojunction has potential application in optoelectronic devices, because it may combine the emission from the rare-earth-doped transpa
