Wear Of A Mica-containing Glass-ceramic

Kucuk, Taylan 01 January 2003 (has links) (PDF)
Tribological properties of a mica glass-ceramic designed for use in dental applications were assessed experimentally in accord with the ASTM pin on disk technique. The glass ceramic was produced through controlled crystallization of the glass in the system SiO2, Al2O3, CaO, MgO, K2O, and F. Crystallization was accomplished by subjecting the parent glass to a regulated heat treatment that resulted in the nucleation and growth of crystal phases formed in the glass. The tests were conducted by sliding a zirconia ball against the glass and glass ceramic disk. The friction coefficient and wear rate were determined as functions of the applied load, sliding speed and sliding time in ambient laboratory conditions and in acidic and basic solutions. The friction coefficient was monitored during the tests. The wear volumes determined from surface profile traces obtained on the wear tracks after completion of the tests were used for calculation of the wear rates. The wear rates increased with increasing applied load and sliding speed but decreased with increasing sliding distance. Results were correlated with the tribological properties of the parent glass, and tribological properties of selected glasses, glass-ceramics and ceramics reported in the literature.

Graphene Mediated Saturable Absorber on Stable Mode-locked Fiber Lasers Employing Different Dispersants

Huang, Shr-Hau 04 September 2012 (has links)
Stable passive mode-locked fiber lasers(MLFLs) employing graphene saturable absorber (SA) are demonstrated. The graphene were dispersed in de-ionized water by two different dispersants including fluorinated mica clay (Mica) and poly(oxyethylene)-segmented imide (POEM). Using the SA made by graphene dispersed in Mica with thickness and concentration product (TCP) of 36 (£gm*wt%), the MLFLs exhibited pulsewidth, 3-dB spectral bandwidth, and modulation depth (MD) of 382 fs, 6.80 nm, and 2.57%, respectively. The graphene dispersed in POEM provides a TCP of 38 (£gm*wt%) to make the MLFLs deliver pulsewidth, 3-dB spectral bandwidth, and MD of 422 fs, 6.35 nm, and 1.70%, respectively. In comparison, the graphene SA dispersed by Mica performs a better MLFL pulse quality than that dispersed by POEM. Lastly, for investigating the dispersed uniformity between Mica and POEM, we randomly chose 9 pieces and measured the MLFL performance. The result showed that using the SA made by graphene dispersed in Mica with TCP of 36 (£gm*wt%), the MLFLs exhibited pulsewidth of 393¡Ó14 fs, By contrast, the graphene dispersed in POEM provided a TCP of 38 (£gm*wt%) to make the MLFLs delivered pulsewidth of 442¡Ó32 fs. This result reveals that graphene SA film dispersed by Mica exhibited better uniformity than POEM. The MLFL of 21-layes CVD process graphene SA showed a pulsewidth of 432.47 fs, a bandwidth of 6.16nm, and a time-bandwidth product (TBP) of 0.323. This result showed that the solution blending process graphene SA exhibited better MLFL performance than CVD.
