The complex permittivity of films of polyether ether ketone (PEEK) has been investigated over a wide range of frequency. There is no relaxation peak in the range of 1Hz to 10 Hz but in the lowfrequency side (10 Hz) there is an evidence of a peak that also can be observed by thermally stimulated discharge current measurements. That peak is related with the glass transition temperature (T g ) of ...

Recently, 3D-printed polyether-ether-ketone (PEEK) components have been shown to offer many applications in state-of-the-art electronics, 5G wireless communications, medical implantations, and aerospace components. Nevertheless, a critical barrier that limits the application of 3D printed PEEK is their weak interfacial bonding strength. Herein, we propose novel method improve this unsatisfied s...

Abstract Dental implant can be defined as the process of inserting an artificial tooth in place natural tooth. This consists a) abutment b) Custom made crown and (c) Implant. implants are two major types Endosteal Subperiosteal Implant, endosteal is more widely used nowadays very rare. Apart from types, it also has variety materials usage. The titanium zirconia. Both zirconium have lots disadva...

In the present study, friction and wear behaviors of Si3N4-hBN(Hexagonal boron nitride) ceramic composites against polyether-etherketone in artificial seawater were investigated, sliding speed was varied from 0.52 to 1.73 m/s study effect. It found that coefficients rates decreased with increase for Si3N4-hBN (with hBN content ranging 5% 20%) PEEK(Polyether-ether-ketone); pairs represented an u...
