Investigation of Ni-base coatings after corrosion test
Inconel 625 and 686 are Ni–Cr–Mo alloys used for its high strength, outstanding corrosion resistance, and excellent fabricability. For this reason, these alloys are typically used as a one of the most important coating material and can be applied to chemical and petrochemical plants, power generation sector, heat exchanger tubing for boilers of waste incinerators. To perform the Ni-base weld overlays, without introducing too much Fe, a new weld technique called Cold Metal Transfer (CMT) was used. This paper presents the mechanisms of high-temperature corrosion, microstructure and chemical composition of boiler elements after the waste incineration form ashes at 650°C from 500 h. Microstructure examinations of the Inconel 625 and Inconel 686 corroded surface were carried out by scanning electron microscopy (SEM) supported by energy dispersive spectroscopy (EDS). The phase compositions of the corroded surfaces were carried out by means of X-ray diffraction.
Celem pracy jest analiza mikrostruktury, składu fazowego oraz chemicznego napoin ze stopów Inconel 625 i Inconel 686 po wysokotemperaturowym utlenianiu w temperaturze 650°C przez 500 h w popiołach pochodzących ze spalarni odpadów.
