Auto-Drawing and Functionalization by Vapor-Phase Assisted Polymerization on Solid Surface
Full text linkFormation of two- and three-dimensional micro architectures with chemical functions was verified by photo-vapor phase assisted surface polymerization (VASP) of functional monomer vapors combined with an auto-drawing system manipulated by prescribed programs. The surface modification by the photo-VASP of styrene vapor progressed rapidly, and a fine lines-pattern of photo-mask was transcribed as the corresponding polymer accumulations on poly(methyl methacrylate) (PMMA) substrate surfaces. Substrate surface modified by photo-VASP of acrylic acid showed reversible changes in hydrophilic/hydrophobic properties according to repeating external chemical stimuli. The successive auto-drawing by photo-VASP of three kinds of monomer vapors was examined under spot illumination from a fine optical fiber on an X-Y stage manipulated by a prescribed program, resulting in the production of a pre-designed functional structure by successful accumulations of corresponding polymers on the substrate surface
Strain Rate and Temperature Insensitiveness of Notch-bend Strength for High Si Ductile Cast Iron
No full textThe notch-bend strength (σb,max) was investigated for High Si Solid Solution Strengthened Ferritic Ductile Cast Iron (EN-GJS-500-14) with varying the strain rate at room temperature. The notch-bend strength was also compared with the conventional ferrite-pearlite type ductile cast iron JIS-FCD500 and JIS-FCD700. Then, the application of the high Si ductile cast iron to wide industrial fields was discussed. Dynamic three-point bending tests were conducted on Charpy V-notch specimens in the range of stroke speed, 10-3~102 mm/s, at -20~22°C. The load-displacement curve for ductile fractured specimens shows that the load (P) steeply increases to the peak value (Pmax; about 10 kN) and then decreases, similar to that in the case of instrumented Charpy impact test. Even though the absorbed energy of fracture process was in the lower shelf region, the notch-bend strength did not decrease with increasing the strain rate as far as the fracture origin is ductile. It was found that the notch-bend strength is insensitive to the strain rate. The notch-bend strength (σb,max) of high Si ductile cast iron at -20°C was still equal to that at 22°C, indicating σb,max is insensitive to the temperature as well as the strain rate. High Si ductile cast iron EN-GJS-500-14 and the conventional ductile cast irons JIS-FCD500 and JIS-FCD700 show nearly the same lowest σb,max in the range of strain rate, 1.5×10-4~2.0×100s-1 at -20°C. Therefore, we think that the high Si ductile cast iron has wide industrial application potentiality
