TI  - NiCoCrAlX (X = Y, Hf and Si) Bond Coats by Cold Spray for High Temperature 
      Applications.

AB  - MCrAlX powder compositions (M = Ni,Co and X = Y, Hf, Si or combination) are often 
      thermally sprayed via vacuum plasma spray (VPS), low pressure plasma spray (LPPS) 
      or high velocity oxy-fuel to produce high temperature oxidation and hot corrosion 
      resistant bond coats for thermal barrier coatings (TBCs). Cold spray technology 
      is currently considered as a promising alternative to the traditional thermal 
      spray solutions, having the advantage of delivering oxide-free and very dense 
      metallic coatings at relatively lower costs compared to VPS and LPPS. NiCoCrAlY 
      and NiCoCrAlYHfSi bond coats were deposited using a high pressure cold spray 
      system and the influence of feedstock properties on the deposited bond coats were 
      investigated. To improve NiCoCrAlYHfSi bond coat deposition, laser assisted cold 
      spray (LACS) was employed. The results show that LACS can be successfully used to 
      deposit this particular powder while eliminating nozzle erosion and low 
      deposition efficiency disadvantages observed with conventional cold spray. To 
      identify the optimal LACS setup for deposition of dense and uniform coatings, 
      different laser/spray jet configurations were examined. TBCs with bond coats 
      sprayed at the optimal configuration were assessed isothermally at 1150  degrees C in air 
      for up to 500 h, and the results showed formation of a thermally grown oxide 
      layer composed of predominantly Al(2)O(3) with embedded small clusters of 
      Hf-Y-rich oxides.
