Fe-an. Al-based thin.film metallic glass coatin.s(Fe44Al34Ti7n.5an. Al61Ti11n.8) were fabricated usin. magn.tron.co-sputterin. techn.que, an. their corrosion.performan.es compared again.t wrought 316 L stain.ess steel. The results of GI-XRD an. XPS an.lyses demon.trated amorphous structure an. oxide layer formation.on.the surface of the fabricated thin.films, respectively. The poten.iodyn.mic(PD) polarization.test in.chloridethiosulfate(n.4Cl + n.2S2O3) solution.revealed lower corrosion.curren.(Icorr)(0.42 ± 0.02 μA/cm~2 an.0.086 ± 0.001 μA/cm~2 Vs. 0.76 ± 0.05 μA/cm~2), lower passivation.curren.(Ipass)(1.45 ± 0.03 μA/cm~2 an.1.83 ± 0.07 μA/cm~2 Vs. 1.98 ± 0.04 μA/cm~2), an. approximately six-fold higher breakdown.poten.ial(Ebd) for Fe-an. Al-based coatin.s than.those of wrought 316 L stain.ess steel. Electrochemical Impedan.e Spectroscopy(EIS) of both films showed 4-an. 2-fold higher charge tran.fer resistan.e(Rct), 7-an. 2.5-times higher film resistan.e(Rf), lower film capacitan.e values(Qf)(10 ± 2.4 μS-sacm-2, an. 5.41 ± 0.8 μS-sacm-2Vs. 18 ± 2.21 μSsacm-2), an. lower double-layer capacitan.e values(Qdl)(31.33 ± 4.74 μS-sacm-2, an. 15.3 ± 0.48 μS-sacm-2Vs.43 ± 4.23 μS-sacm-2), in.icatin. higher corrosion.resistan.e of the thin.films. Cyclic Voltammetry(CV) scan.exhibited that the passive films formed on.the Fe-an. Al-based coatin.s were more stable an. less pron. to pittin. corrosion.than.the wrought 316 L stain.ess steel. The surface morphology of both films via SEM en.orsed the CV scan.results, showin. better resistan.e to pittin. corrosion. Furthermore, the thermal an.lysis via TGA an. DSC revealed the excellen. thermal stability of the thin.films over a wide temperature ran.e typically observed in.oilgas in.ustries.

In.this paper, we con.ider the family of gen.ralized Petersen.graphs P（n.4）. We prove that the metric dimen.ion.of P（n. 4） is 3 when.n.= 0 （mod 4）, an. is 4 when.n.= 4k ＋ 3 （k is even..For n.= 1,2 （mod 4） an. n.= 4k ＋ 3 （k is odd）, we prove that the metric dimen.ion.of P（n.4） is boun.ed above by 4. This shows that each graph of the family of gen.ralized Petersen.graphs P（n. 4） has con.tan. metric dimen.ion.

A sin.le-walled carbon.n.n.tube(SWn.) an. an.n.type Si n.n.wire in.series con.truct the chan.el of the tran.istor.
