1Advanced cold spray technology:Deposition characteristics and potential applications显示文摘Cold spray technology,originated from the Institute of Theoretical and Applied Mechanics Siberian branch of the Russian Academy of Sciences,is a rapidly emerging industrial coating technology.Cold sprayed particles with high-velocity impact onto a substrate so as to induce severe plastic deformation and then create a deposit.For its low temperature and high velocity compared with thermal spraying,the cold spraying process is increasingly used in the industries for protective coating.The deposition characteristics of the particles,coating formation and bonding mechanism of the cold spraying process are different from thermal spraying.Many theory investigations of the cold spraying process contribute to the development of the high performance coatings,which makes the cold spraying process as a popular research field.Presently,the deposition characteristics,bonding mechanism,process optimization as well as classical applications of the cold spraying technology in the past are reviewed,and the interesting points for the further development,optimization and applications of this technology are also recommended.WU XiangKun ZHANG JiShan ZHOU XiangLin CUI Hua LIU JingChun 2012Science China(Technological Sciences)2012,55,2:5
2石墨烯复合微粒喷射成型行为模拟与实验显示文摘利用ANSYS/LS-DYNA模拟分析了不同冲击速度下石墨烯复合微粒嵌入半固态酚醛树脂基体行为,分析研究了嵌入瞬间石墨烯复合微粒与基体塑性变形现象以及结合深度变化规律。研究表明,复合微粒与基体的塑性变形随冲击速度增大而增大,当冲击速度超过600m/s时,复合微粒完全嵌合在基体中,此时,基体有效塑性应变发生突变,体系发生绝热剪切失稳现象。同时,更多的动能向内能转化,使基体由弹性状态转变为粘弹性状态,从而有助于复合微粒与基体结合。当冲击速度小于600m/s时,复合微粒未完全嵌合在基体中。最后通过实验验证上述结论的正确性。吴海华 范雪婷 高纪强 王道 罗烨 王曹文 2020材料科学与工程学报2020,38,6:0
