| 1 | Mechanical assisted electroless barrel-plating Ni-P coatings on magnesium alloy显示文摘A mechanically assisted electroless barrel-plating Ni-P was carried out in a rolling drum containing Mg alloy specimens and ceramic balls, which was submerged in a bath containing electroless plating solution. It is demonstrated that the Ni-P coatings deposited by this novel technique have a crystallized Ni-P solid solution structure, showing fine-grains, higher hardness, and higher corrosion resistance compared with the conventional electroless plated amorphous Ni-P coatings. After heat treatment at 400 ℃ for 1 h, the structure of such Ni-P coatings were transformed to a structure with Ni-Ni3P double phases, and cracks in these coatings could not be observed, whereas cracks appeared seriously in the conventional electroless plated Ni-P coating after same heat treatment. Therefore, both hardness and corrosion resistance of these Ni-P coatings can be improved further by heat treatment. All of these beneficial effects can be attributed to the role of mechanical attrition during the mechanically assisted electroless barrel-plating process. | Zhaoxia PING Juntao YUAN Yedong HE Xiaogang LI | 2009 | Acta Metallurgica Sinica(English Letters)2009，22，3： | 6 |
| 2 | Mechanically Assisted Electroless Barrel-plating Ni-P Coatings Deposited on Carbon Steel显示文摘A mechanically assisted electroless (MAE) barrel-plating technique has been developed to deposit Ni-P coatings on carbon steel.The mechanical treatment was carried out in a rolling drum containing carbon steel specimens and glass balls of 2-3 mm diameter,which was submerged in a bath containing electroless plating solution.The coatings are Ni-polycrystalline and have a fine grained structure and smooth surfaces.The hardness and corrosion resistance of the novel coatings are considerably improved compared with the conventional electroless (CE)-plated Ni-P coatings,which are amorphous.After heat treatment at 400 C for one hour,cracks and pores are observed in the CE-plated Ni-P coating,while no cracks appear in the MAE barrel-plated Ni-P coating.The improved properties of the MAE barrel-plated Ni-P coatings demonstrate the advantages of this novel technique,wide applications of which will be found in industries. | Zhaoxia Ping Cuoan Cheng Yedong He | 2010 | Journal of Materials Science & Technology2010，26，10： | 4 |
| 3 | Enhancing the mechanical and anticorrosion properties of 316L stainless steel via a cathodic plasma electrolytic nitriding treatment with added PEG显示文摘A cathodic plasma electrolytic nitriding(CPEN)treatment with a urea aqueous solution was performed on 316L stainless steel to rapidly improve its surface properties in this work.Test results show that the PEG2000 macromolecules increased the nitriding energy via enhancing the ability to bond the produced gas film to the metal/electrolyte interface.The cross-sectional morphologies indicate that a thick nitrided layer was obtained when the urea concentration was 543 g I^-1,corresponding to a Vickers hardness 450 HV(0.1),which was 3.5 times larger than that of the substrate.The nitrided layer mainly contained expanded austenite(γN),oxides and iron nitrides(e.g.,Fe3O4 and FeN(0.076)).In terms of its performance,coefficient of friction(COF)of the nitride layer decreased to nearly two-thirds that of the untreated layer,and the passivation current densities of the nitrided sample in a 3.5%NaCl solution decreased by an order of magnitude compared to that of the substrate.Therefore,the approach presented herein provides an attractive way to modify the effect of CPEN in a urea aqueous solution. | Tianyi Zhang Junsheng Wu Lei Jin Zhan Zhang Wan Rong Bowei Zhang Yi Wang Yedong He Wei Liu Xiaogang Li | 2019 | Journal of Materials Science & Technology2019，35，11： | 3 |
| 4 | Surface Microstructure and High Temperature Oxidation Resistance of Thermal Sprayed NiCoCrAlY Bond-Coat Modified by Cathode Plasma Electrolysis显示文摘The surface properties of the air-plasma sprayed bond-coat have been modified by cathode plasma electrolysis(CPE). After modification, a re-melted layer without obvious pores and oxide stringers is formed,the gain size of re-melted layer is approximately 80–120 nm. It is shown, from cyclic oxidation at 1100℃,that a thin oxide scale mainly composed of α-Al_2O_3 has been formed on the modified bond-coat and the oxidation resistance of the modified bond-coat has been significantly improved. Such beneficial result can be attributed to following effects: during CPE process, the plasma discharges with high temperature take place on the bond-coat surface. With plasma discharge treatment, the surface is melted and quickly re-solidified, the grain size decreases, and the pores and oxide stringers disappear. During cyclic oxidation, owing to the above modification of surface properties, the critical content of Al for selective oxidation is significantly decreased. Therefore, a continuous Al_2O_3 scale is formed. | Shunjie Deng Peng Wang Yedong He Jin Zhang | 2017 | Journal of Materials Science & Technology2017，33，9： | 3 |
| 5 | Ni-P-SiC composite coatings electroplated on carbon steel assisted by mechanical attrition显示文摘Ni-P-SiC composite coatings were electroplated on carbon steel substrate assisted by mechanical attrition(MA).The MA action was conducted by dispersing glass balls on the cathodic surface,vibrating in the horizontal direction.The experimental results show that,under the assistant of MA action,the adhesion of Ni-P-SiC coating on the steel substrate can be improved effectively,and the Ni-P-SiC coatings exhibit a crystallized structure and Ni-P matrix can combine tightly with SiC particles,and the hardness and corrosion resistance of these coatings increase markedly.During heat treatment,the defects produced in conventional Ni-P-SiC composite coatings can be avoided assisted by MA action.Both of the wear resistance and corrosion resistance of these coatings can be improved further. | Zhaoxia PING Guoan CHENG Yedong HE | 2010 | Acta Metallurgica Sinica(English Letters)2010，23，2： | 2 |
