| 2 | Analysis of Machinable Structures and Their Wettability of Rotary Ultrasonic Texturing Method显示文摘Tailored surface textures at the micro- or nanoscale dimensions are widely used to get required functional performances.Rotary ultrasonic texturing(RUT) technique has been proved to be capable of fabricating periodic micro- and nanostructures. In the present study, diamond tools with geometrically defined cutting edges were designed for fabricating different types of tailored surface textures using the RUT method. Surface generation mechanisms and machinable structures of the RUT process are analyzed and simulated with a 3D-CAD program. Textured surfaces generated by using a triangular pyramid cutting tip are constructed. Different textural patterns from several micrometers to several tens of micrometers with few burrs were successfully fabricated, which proved that tools with a proper two-rake-face design are capable of removing cutting chips efficiently along a sinusoidal cutting locus in the RUT process. Technical applications of the textured surfaces are also discussed. Wetting properties of textured aluminum surfaces were evaluated by combining the test of surface roughness features. The results show that the real surface area of the textured aluminum surfaces almost doubled by comparing with that of a flat surface, and anisotropic wetting properties were obtained due to the obvious directional textural features. | XU Shaolin SHIMADA Keita MIZUTANI Masayoshi KURIYAGAWA Tsunemoto | 2016 | Chinese Journal of Mechanical Engineering2016，29，6： | 6 |

| 5 | Effects of Topography and Modified Layer by Plasma-Shot Treatment on High-Speed Steel显示文摘In this study,plasma shot(PS)treatment was applied to high-speed steel(HSS)surfaces using a titanium carbide electrode to confirm the effect of discharge current(Ip)on the formation of a single dimple and analyze a modified layer.The roughness of modified surfaces increased when Ip increased,and energy-dispersive X-ray spectrometry showed an increase in titanium atom density whenIp and electrode consumption volume(Ve)increased.A friction test confirmed that the modified surface's friction was reduced by discharge dimples under low-load conditions.Vickers hardness test confirmed that the hardness of the modified surface was-300-600 HV higher than that of an untreated HSS surface.Moreover,it increased with an increase inIp.However,application of PS treatment to the edge of surfaces on the workpiece caused shape deterioration.The deterioration size of the edge of the modified layer increased when Ip increased.To solve this issue,we propose a novel method named position-adjusted PS(PA-PS)treatment.PA-PS treatment is used to adjust the end of the electrode in the order of tens of micrometers from the edge of the workpiece to avoid the deterioration of the edge form.Under Ip=21 A,PA-PS formed a modified layer without deteriorating the edge shape of the workpiece,thus confirming the PS characteristics applied to HSS surfaces.Moreover,PA-PS treatment solved the shape deterioration of the edge on modified surfaces via PS treatment. | Yorihito Shibata Yusuke Sakairi Keita Shimada Masayoshi Mizutani Tsunemoto Kuriyagawa | 2020 | Nanomanufacturing and Metrology2020，3，2： | 0 |
