Al–Pt MOCVD coatings for the protection of Ti6242 alloy against oxidation at elevated temperature
Results on isothermal oxidation at 873 K for 90 h of Al–Pt coatings on Ti6242 coupons are reported. These coatings were obtained by low temperature, low pressure metalorganic chemical vapor deposition using Me3(MeCp)Pt(VI) and dimethylethylamine alane. Three coating architectures were investigated, namely pure Al, Pt and Al sequential sublayers, and co-deposited Al and Pt. Oxidation kinetics re...
متن کاملA Review on Titanium Nitride and Titanium Carbide Single and Multilayer Coatings Deposited by Plasma Assisted Chemical Vapor Deposition
In this paper, we reviewed researches about the titanium nitride (TiN) and titanium carbide (TiC) single and multilayer coatings. These coatings were deposited by the plasma assisted chemical vapor deposition (PACVD) technique. Plasma-based technologies are used for the processing of thin films and coatings for different applications such as automobile and aerospace parts, computer disc drives,...
متن کاملAnti-corrosive Properties of CeO2 Conversion Coatings on Aluminum Alloy 2024 Prepared by Dip Immersion Method
As an alternative to chromate conversion coatings, rare-earth coatings especially cerium, because of the low toxicity, have attracted considerable attention. Using dip immersion method, cerium-based conversion coating was deposited on aluminum 2024. Corrosion resistance was studied in 3.5 wt.% NaCl solution using potentiodynamic polarization, electrochemical impedance spectroscopy, and surface ...
متن کاملAn Updated Review of the Fatigue Behavior of Components Coated with Thin Hard Corrosion-Resistant Coatings
In the present manuscript, an extended review on the state of the art on the experimental and numerical characterization of the fatigue behavior of Physically Vapor Deposited (PVD) and Chemically Vapor Deposited (CVD) thin hard coatings is presented. The current application and development fields of PVD and CVD treatments are analysed, focusing on the advantages granted by the adoption of these...
متن کاملTi-Cr-N Coatings Deposited by Physical Vapor Deposition on AISI D6 Tool Steels
In this study, physical vapor deposition (PVD) Ti-Cr-N coatings were deposited at two different temperatures 100 and 400ºC on hardened and tempered tool steel substrates. The influence of the applied deposition temperature on the physical and mechanical properties of coatings such as roughness, thickness, phase composition, hardness and Young’s modulus were evaluated. Phase compositions were st...
