Thermodynamic analysis of covering blades of gas-turbine engineы made of heatproof nickel alloys with protection diffusion coatings with tantalum undercoat
Engineering Education # 07, July 2013 DOI: 10.7463/0713.0583284 This work presents results of thermodynamic studies and searching for a rational chemical activation dopant for deposition of tantalum from the gaseous phase onto surfaces of parts of gas-turbine engines made of heatproof nickel alloys in order to increase the diffusion stability of heatproof aluminide coatings. Calculations showed a possibility of using nickel dichloride for tantalum and tantalum-chromium coating of nickel alloys. During this investigation several restrictions on the number of additional alloying elements in the saturating mixture were discovered. An effective amount of chromium for the combined process of tantalum-chromium coating was also determined.
