Abstract
Thermal spray coatings can be used for high temperature
corrosion protection of heat exchanger surfaces in power
plant boilers. In this study, several thermal spray
coatings with high chromium content were manufactured
with HVOF (high velocity oxy-fuel) technique, and their
mechanical properties and high temperature corrosion
resistance were tested and analysed. The coating
materials included NiCr, IN625 and iron based steel alloy
with a nanoscale microstructure Nanosteel SHS9172. High
temperature corrosion testing was made in NaCl-KCl-Na2SO4
salt with controlled H2O atmosphere, in temperatures 575
and 625 C. The effect of coating process and following
characteristics of the coatings on high temperature
corrosion protection properties was analysed. The
corrosion test results of the coatings were compared to
corrosion resistance of bulk materials (X20, Alloy 263
and Sanicro 25)
