(2011) revealed that coating had potential to lower the high temperature corrosion using detonation gun spray method to deposit Ni-20Cr onto ASTM A213 TP347H boiler steel
. Manpreet (2011) proved [Cr.sub.3][C.sub.2]-NiCr coating to be highly protective against corrosion.

in an aggressive environment at 750[degrees]C," Surface and Coatings Technology, vol.
The 21 papers consider such topics as the mechanical and structural characterization of rapidly solidified aluminum-iron-magnesium alloys, the effect of hydrogen on the corrosion of rare-earth-containing magnesium alloys in sodium sulfate solution, the effect of adding zinc and zirconium on the microstructure and texture of cast and wrought magnesium alloys with different content of calcium, the electron microscopy investigation of an Inconel 625 weld overlay on boiler steel
, and microstructural investigations of cracks in turbine wheels in car engine turbochargers.
The objective of the present work is to investigate the role of detonation gun spray method on the hot corrosion resistance of Stellite-6 and Stellite-21 coatings on SAE 431 boiler steel
. Hot corrosion tests of specimens were carried out in the molten salt environment [Na.sub.2]S[O.sub.4]-82%[Fe.sub.2][(S[O.sub.4]).sub.3] at 900[degrees]C for 50 cycles of one hour duration.
The influence of the long-term operation on tensile properties of boiler steels
has been investigated in [1-8].
A detailed investigation on high-temperature corrosion of Russian boiler steels
under the influence of oil shale ash was carried out at Thermal Engineering Department of Tallinn University of Technology (TED TUT) during the last four decades .
