陶瓷涂层结合强度影响因素研究及在水压柱塞上的试验

Research of affecting Bonding Strength of Ceramic Coating Thermal-sprayed on the Metal Substrate Surface and the Experiment in Tap Water Hydraulic Piston

综合对比分析了热喷涂方法、粉末结构、粉末成份、喷涂参数、工艺、金属基体预处理方法等对涂层结合强度的影响 ,提出了提高结合强度的一些措施 ,使金属陶瓷能承受一定的冲击与振动 ,并能应用于水压传动元件上。本文介绍了金属陶瓷在水压冲击机构中的试验情况。

The properties of engineering ceramics and the testing methods of coating bonding strength was synthesized and evaluated,and the effect of the methods of thermal spraying,powder structures,powder compositions thermal spraying parameters and preparative treatment methods of the metal substrate to adhesive bonding strength of ceramic coating were analyzed,which aim at finding out the right way of successfully using the thermal spraying coated ceramet to the pressurized-water driving impact piston/cylinder.The experimental result in tap water hydraulic piston was also introduced.
