Study of multilayer and multi-component coatings deposited using cathodic Arc technique on H-13 hot work steel for die-casting applications
Die casting process is used since long, but even today problems like erosion, corrosion, soldering and sticking affect die life. These dies undergo thermal cyclic loads from 70 oC to 600 oC during processing. Physical Vapor Deposition (PVD) hard coating can play an important role in such extreme applications. In the present work, we report the use of Chromium based multila...
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...
متن کاملModeling of Chemical Vapor Deposited Zirconia for Thermal Barrier and Environmental Barrier Coatings
Thermal and environmental barrier coatings are important components of current and future energy systems. Such coatings – applied to hot, metallic surfaces in combustors, heat exchanger and turbines – increase the allowable operating temperature and increase the efficiency of the energy system. Because of its low thermal conductivity and high thermal expansion yttria-stabilized zirconia (YSZ) i...
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 کاملChemically Vapor Deposited Ysz for Thermal Amd Environmental Barrier Coatings
Yttria-stabilized zirconia (YSZ) has been used as a thermal/environmental barrier coating for gas turbine engine blades. Current methods of fabrication include air plasma spraying (APS) and electron-beam physical vapor deposition (EB-PVD). The APS technique results in a coating that loses effectiveness with thermal cycling. The EB-PVD technique deposits a columnar microstructure which accommoda...
