Study on the (Fe,Cr) 7C3 particles reinforced iron-based composite coating Libin Niu1,a, *, Zhen Xu1,b, Jianhong Peng2,c 1 School. of Material Science and Engineering, Xi’an University of Science and Technology, China 2College of Physics and Electronic Information Engineering,Qinghai Nationalities University,China *,a dy059@126.com, b xuzhen0913@163.com, c dy059@163.com Keywords: Reinforcement, In situ, Composite coating, (Fe,Cr) 7C3 Abstract An iron based composite coating reinforced by (Fe,Cr) 7C3 particles, with a thickness of 4.0 mm, was fabricated on the ductile cast iron substrate by means of a centrifugal casting and in situ techniques.
However, as a wear resistant material, its application is still limited [5-7].
Experimental processing Chromium wires (0.25 mm in diameter) and ductile cast iron were used as the raw materials.
In order to obtain the high volume fraction of the (Fe,Cr) 7C3 phase, the original materials should contain relatively high Cr and C contents; their chemical compositions are Fe–3.61C–2.50Si–0.28Mn–0.45Cu–0.04Cr–0.017P–0.014S (wt-%) for ductile cast iron and Fe–0.12C–0.79Si–17.54Cr–0.011P–0.013S (wt-%) for Cr wire, respectively.

Results and Discussion Effect of Na2CO3 on NOx emission Sodium is one of the mineral materials in coke, which had suppressive effect on the NOx formation in coke combustion [8].
Fig.4 Effects of magnesium-based materials on NOx emission during coke combustion Fig.3 Effects of calcium-based materials on NOx emission during coke combustion Effect of magnesium-based additives on NOx emission NOx emissions in the combustion of coke loading magnesium-based additives were shown in Fig.4.
During the process of coke combustion, NOx is mainly reduced to N2 by the burning coke and CO gas generated in the combustion, some mineral materials, such as Na and Ca, contained in the coke, play a catalytic role for NOx reduction reactions.
