Abstract

CRUD deposition tests were carried out on several micro-orifice specimens in a Hastelloy C-276 and a SS 316L flow loop. The results showed that irrespective of the material used for the construction of the discs (SS 304L, Titanium, Alloy 690, Zirlo and Magnesia stabilised Zirconia) no significant differences in term of radial CRUD build-up were observed. The effect of the Ni and Fe cations dissolved in the water was also investigated; the results revealed that CRUD build-up rate increased with the ferrous ions concentration and decreased with nickel ions. Finally, SEM and Energy Dispersive X-Ray Spectroscopy were used to characterise the oxide morphology showing higher particulate build-up for the specimens tested in the Hastelloy autoclave.
