1航空活塞发动机缸体再制造强化研究进展显示文摘航空活塞发动机在航空、军用装备领域发挥着重要作用,因其作为主要动力装置,决定了其工作环境为高温、高压等苛刻环境,导致缸体内壁严重损伤和失效。介绍了以再制造方式来修复损伤的航空活塞发动机,通过内孔热喷涂技术在缸套内壁沉积涂层,提升装备抵抗严苛外界环境的影响。以喷涂粒子、基体为主要研究对象,改变飞行喷涂粒子、基体的物性参数,在内孔件沉积耐磨损、耐高温、耐腐蚀等性能优质的涂层,延长航空活塞发动机的使用寿命,保证其可靠性服役。谭燕 丁发军 2020热加工工艺2020,49,16:4
2Protection Performance of Plasma Sprayed Al_(2)O_(3)-13 wt%TiO_(2) Coating Sealed with an Organic-inorganic Hybrid Agent显示文摘An organic-inorganic hybrid sealing agent was fabricated and used in the plasma sprayed Al_(2)O_(3)-13 wt%TiO_(2)coating,and conventional silicone agent was also used for comparison.Protection performance of the coatings was comprehensively evaluated based on both anti-corrosion and anti-biofouling properties.The results reveal that the sealing treatment is remarkably useful to decrease the porosity of the coating,and the porosity of the coating sealed with the hybrid agent is only 0.035%.Immersion corrosion test and Tafel polarization test reveal that the sealed coating with the hybrid agent exhibits a better corrosion resistance by compared with the coating sealed with silicone agent.The corrosion current density i_(corr) of the hybrid agent sealed coating is only 0.7×10^(-6)A·cm^(-2).Moreover,anti-biofouling tests both in the outdoor analogue hydraulic environment and in the natural marine environment prove that the mentioned novel coating presents a better combination of corrosion resistance and anti-biofouling property by compared with the other coatings,and it could be used as a protection of metal components in the marine environment.张凯城 周泽华 DENG Yong WANG Guangyu WANG Zehua WU Lintao YANG Guangheng 2022Journal of Wuhan University of Technology(Materials Science)2022,37,3:1
