Abstract To enhance the surface osseointegration ability of carbon fiber reinforced polyetheretherketone (CF/PEEK), an economical method continuous laser irradiation was employed to improve its wettability. The effects different energy densities on morphology, chemical structure, and wettability were systematically analyzed. results showed that at lower density irradiation, part PEEK matrix removed, forming a rough corrugated surface. At higher densities, fibers exposed fractured when damage...
Bi2Te2.7Se0.3 of high performance doped with Gd bulk materials was prepared by a pressure (6.0 GPa) sintering (HPS) method at 593 K, 633 673 K and 693 K. The sample then annealed for 36 h in vacuum phase composition, crystal structure morphology the were analyzed X-ray diffraction scanning electron microscopy. electric conductivity, Seebeck coefficient, thermal conductivity aspects measured from 298 to 473 results show that doping has great effect on thermoelectric properties samples....
With the increasing requirements for surface quality of workpiece, many kinds hybrid manufacturing have developed recently. Ultrasonic vibration-assisted laser polishing (UVLP) is a new method. Different from traditional method applying ultrasonic vibration on this article applies lens. Besides, thermal mechanisms 304 stainless steel polished by (TLP) and UVLP were analyzed to reveal influence effect. The lens transforms into an intermittent process, which affects energy density surface....
This paper proposed a new electromagnetic tomography (EMT) system based on tunnel magnetoResistance (TMR) for the detection of permeability, in which measured sensitivity is not affected by excitation frequency. In addition, we firstly put forward an improved simulation model, has similar distribution magnetic field with real system. Afterwards, perturbation method and direct were used to calculate matrices respectively, some experiments performed reconstructing images correlation...
Bi2Sr2Co2Oy thin films were grown on 10° vicinal-cut Al2O3 (0001) single crystalline substrates by pulsed laser-deposition techniques with in situ annealing, post-annealing and non-annealing process, respectively. The pure phase film was obtained a process. result of X-ray diffraction showed that obviously c-axis preferred orientation. laser-induced thermoelectric voltage signals detected films, which originated from the anisotropy Seebeck coefficient. maximum peak value strong could reach...
