| 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 | 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 |
| 3 | In-flight particle characterization and coating formation under low pressure plasma spray condition显示文摘Yttria-stabilized zirconia( YSZ) coatings were deposited by low pressure plasma spray( LPPS) in 1.0× 10~4 Pa,1.5 × 10~4 Pa,and 2.5 × 10~4 Pa. Both in-flight particle diagnostic detected by DPV-2000 system and ANSYS-FLUENT software were used to study the connection between the parameters of flying particles and the coating formation,which might help to recognize the relationship between the operation parameters and the coatings quality. The results of simulation showed that particles in a lower spray pressure could achieve a higher velocity. The particle velocity was around 380 m/s at a distance of 35 cm from the nozzle at 1.0 × 10~4 Pa while only 300 m/s at 2.5 × 10~4 Pa in actual measurement.The results showed that the velocity of particles increased with decreasing the spray pressure,which might enhance the flattening rate of coatings and thereby decreased the porosity. The deposited YSZ coating with the lowest porosity can be gained under 1.0 × 10~4 Pa condition. | Nan-nan Zhang Dan-yang Lin Ya-li Li Yue Zhang Marie-pierre Planche Han-lin Liao Christian Coddet Fu-yu Dong | 2017 | Journal of Iron and Steel Research(International)2017，24，3： | 2 |
