Failure Analysis of Desulfurization Slurry Circulating Pump and HVOF Coating Protection Technology Progress

Abstract

Failure form and erosion-corrosive mechanism of desulfurization slurry circulating pump were analyzed comprehensively, its protection status and HVOF spraying protection technology research were discussed, the technical characteristics and good prospects of HVOF applied in the slurry circulating pump were pointed out in this paper.Keywords: Desulfurization, Slurry circulating pump, Erosion, Corrosion, HVOF

Study of the Wear and Corrosion Performance of Hard Coatings Applied by Different Processes on Low Carbon Steel

“…Equipment can achieve improved performance if properly coated. The recovery of pumps, valves and other parts of industrial machinery using engineered coatings constitutes today one of the most important engineering alternatives [5] [6]. Coatings are thick films and can be applied by several techniques like welding, physical or chemical vapor deposition, electroplating and thermal spraying [7] [8].…”
