Study on Application of the New-Typed Metal Ceramic Composite Coating in the CFBB at High Temperature

Abstract:

In this article, the working conditions and the failure mechanism of the four tubes in Boiler have been studied. On the base of these researches, a new kind of Fe-based/Cr3C2/B-Fe cored wire was designed. And arc spraying technology was used to produce coatings which had high performance and price ratio. The results of test show that the cored wire was easy sprayed with arc spray equipment. The coatings have dense microstructure, good bond with substrate, and excellent wear-resistance and corrosion-resistance at high temperature.This coating can prolong the using life of heated tubes of circulating fluidized bed boiler effectively and is worthy to be widely used in industry.
