| 1 | Effect of Substrate Type on Deposition Behavior and Wear Performance of Ni-Coated Graphite/Al Composite Coatings Deposited by Cold Spraying显示文摘This work focused on the deposition characteristics and wear behavior of Ni-coated graphite mixed with40 vol.% Al(Ni-Gr/Al) composite coatings sprayed on an Al alloy and a steel substrate by cold spraying(CS). The morphology of the ?attened Ni-Gr particles was examined by single-impact tests. Crosssectional microstructure and wear performance of the Ni-Gr/Al composite coatings were studied. Results showed that a larger number of Ni-Gr particles were ?nally bonded with the steel substrate, whereas many craters existed on the Al alloy substrate after the single-impact tests. The coating on the steel substrate had a high thickness, high graphite content and low coe?cient of friction(COF) compared to those on the Al alloy substrate. In addition, the CS coatings presented a homogeneous distribution and uniform morphology of graphite, and a comparative COF to that of conventional thermal sprayed coatings. It was shown that CS could avoid the decomposition and transformation of graphite phase. | Chunjie Huang Wenya Li Yingchun Xie Marie-Pierre Planche Hanlin Liao Ghislain Montavon | 2017 | Journal of Materials Science & Technology2017，33，4： | 4 |
| 2 | Surface complexation modeling of Eu(Ⅲ) adsorption on silica in the presence of fulvic acid显示文摘Humic substances(HS) substantially affect heavy metal(M) adsorption on mineral surfaces. However, quantitative descriptions of ternary systems involving M, HS and mineral surfaces remain unclear. This study examines adsorption in a model ternary system including Eu(III), fulvic acid(FA) and silica, and describes the adsorption of Eu(III) and FA by combining a double-layer model(DLM) and the Stockholm humic model(SHM). SHM explains the binding of H+ and Eu3+ to FA and the DLM for FA and Eu(III) adsorption on silica. Experimental results showed that the presence of FA promotes Eu(III) adsorption at acidic pH values, but decreases it at basic pH values, which indicates the formation of ternary surface complexes. Modeling calculations have shown that two ternary surface complexes are required to describe the experimental results in which Eu3+ acts as a bridge between the surface site and FA. The present study suggests that the discrete-site approach to HS is a promising method for interpreting the adsorption data for M, HS and mineral ternary systems. | YE YuanLv CHEN ZongYuan MONTAVON Gilles JIN Qiang GUO ZhiJun WU WangSuo | 2014 | Science China Chemistry2014，57，9： | 4 |
| 3 | In-situ formation of Ni-Al intermetallics-coated graphite/Al composite in a cold-sprayed coating and its high temperature tribological behaviors显示文摘In this study, cold spraying(CS) was used to deposit a mixture of nickel-coated graphite and 40 vol.% Al powder(Ni-Gr/Al) on a steel substrate aiming to effectively preserve a certain volume fraction of graphite in the deposited Ni-Gr/Al composite coating. The microstructure of the as-sprayed coating and the effect of post-spray heat-treatment(PSHT) temperatures on the in-situ formation of Ni-Al intermetallic phases in coating were studied. The tribological behaviors of the as-sprayed coating and the PSHTed coating under 450?C were tested at 25?C, while the as-sprayed coating was tested at 450?C for comparison.As a result, the Ni-Gr particles showed a homogenous distribution in the coating. The multilayer Ni-Al intermetallics-coated graphite/Al composite coating was achieved in situ after the PSHT of 450?C, where the graphite did decompose at 550?C leaving big pores in the coating. The coefficients of friction(COF)of the CSed coating and the PSHTed coating were measured at 450?C as well as 25?C, which showed a similar tendency, much higher than that of the CSed coating tested at 25?C. The lubrication phase(graphite) improved the formation of a graphite film during sliding friction and decreased the COF, while the hard Ni-Al intermetallic phases contributed to the increase of COF. | Chunjie Huang Wenya Li Marie-Pierre Planche Hanlin Liao Ghislain Montavon | 2017 | Journal of Materials Science & Technology2017，33，6： | 2 |
| 4 | 等离子喷涂复合涂层结构对力学性能影响的有限元分析:网状孔隙结构的影响显示文摘本研究的目的是进一步理解等离子喷涂制备的复合涂层在外力作用下内部应力场的规律。目前,相关方面的报道较少。为了达到这个目的,采用扫描电镜获得高分辨率的涂层照片,经过离散化处理,并进行有限元分析。Al2O3-13TiO2等离子喷涂涂层是一个比较理想的研究目标。通过调整喷涂参数获得了不同的多孔结构,例如孔隙率、裂纹密度、裂纹方向等。数值模拟显示网状孔隙结构对涂层内应力场有显著的影响。同样的,通过改变相的本征力学属性,研究了其它成分的涂层。在理想状态下,仿真结果显示第二相对涂层内部应力场的影响较弱。另外,提出了一种通用的涂层性能分析方法,指出了它的优点和局限性,并强调其重要性(REV)。 | C.
