Indlela yokucubungula ubuso bezinduku ze-laser ze-sapphire crystal ezifakwe i-titanium

Amakristalu etshe le-titanium Ti:Al2O3 (ukuhlushwa kwe-doping okungu-0.35 wt% Ti2O3), izikhala zekristalu ezihambisana nomdwebo wokugeleza kwenqubo yendlela yokucubungula ubuso benduku ye-laser yekristalu yetshe le-titanium yalesi simangaliso ziboniswe ku-Fig. 1. Izinyathelo ezithile zokulungiselela zendlela yokucubungula ubuso benduku ye-laser yekristalu yetshe le-titanium yalesi simangaliso zilandelayo:

<1> Ukusikwa kokuma: ikristalu eliyigugu le-titanium liqala ngokuma, bese lisikwa libe yisikhala esingenalutho esimise okwekholomu ye-tetragonal ngokushiya isabelo sokucubungula esingaba ngu-0.4 kuya ku-0.6 mm ngokuhambisana nosayizi wenduku ye-laser eqediwe.

<2>Ukugaya okuqinile nokuncane kwekholomu: Ikholomu engenalutho igaywa ibe yi-cross-section ye-tetragonal noma ye-cylindrical ene-120~180# silicon carbide noma i-boron carbide abrasives emshinini wokugaya oqinile, enephutha elithambile nelingaphandle kwendilinga elingu-±0.01mm.

<3> Ukucubungula ubuso bokuphela: i-titanium gemstone laser bar icubungula ubuso obunezinhlangothi ezimbili ngokulandelana nge-W40, W20, W10 boron carbide grinding end face kudiski yensimbi. Enqubweni yokugaya, kufanele kunakwe ukukala ukuma kobuso bokuphela.

<4> Ukupholisha ngamakhemikhali: ukupholisha ngamakhemikhali kuyinqubo yokupholisha amakristalu ephepheni lokupholisha ngamaconsi esisombululo sokuchoboza ngamakhemikhali esakhiwe ngaphambilini. Umshini wokusebenza wokupholisha kanye nephepheni lokupholisha ukuze kuhambisane nokunyakaza kanye nokungqubuzana, ngenkathi kusesitsheni socwaningo esiqukethe i-agent yokuchoboza ngamakhemikhali (ebizwa ngokuthi uketshezi lokupholisha) ukuze kuqedwe ukupholisha ngosizo lwe.

<5> Ukucheba nge-asidi: Izinduku zamatshe e-titanium ngemva kokucheba njengoba kuchaziwe ngenhla zifakwa engxubeni ye-H2SO4:H3PO4 = 3:1 (v/v), ekushiseni okungu-100-400°C, bese zicheba nge-asidi imizuzu emi-5-30. Inhloso ukususa inqubo yokucheba ebusweni bebha ye-laser ebangelwa umonakalo we-sub-surface yomshini, nokususa izinhlobo ezahlukene zokupenda, ukuze kutholakale izinga le-athomu lobuqotho be-lattice obubushelelezi nobuyisicaba bobuso obuhlanzekile.

<6> UKWELASHWA KOSHISA KOMHLABA: Ukuze kuqedwe ukucindezeleka komphezulu kanye nemihuzuko edalwe yinqubo yangaphambilini futhi kutholakale umphezulu oyisicaba ezingeni le-athomu, induku yetshe le-titanium ngemva kokuqotshwa nge-asidi yabe isihlanzwa ngamanzi acwebezelwe imizuzu emi-5, kwathi induku yetshe le-titanium yabekwa endaweni engu-1360±20° C. ekushiseni okungaguquki kwehora eli-1 kuya kwele-3 emoyeni we-hydrogen, futhi yaphathwa ngokushisa komphezulu.
