Indlela yokucubungula umphezulu weentonga ze-laser ze-sapphire crystal ezifakwe i-titanium

Iikristale zelitye le-titanium Ti:Al2O3 (uxinzelelo lwe-doping yi-0.35 wt% Ti2O3), apho ii-crystal blanks zazo zihambelana nomzobo wenkqubo yokuhamba kwendlela yokucubungula umphezulu we-titanium gemstone crystal laser rod yale vumbululo iboniswe kwiFig. 1. Amanyathelo athile okulungiselela indlela yokucubungula umphezulu we-titanium gemstone crystal laser rod yale vumbululo ilandelayo:

<1> Ukusikwa kokujonga: ikristale yelitye le-titanium iqala ijonge, ize inqunyulwe ibe yindawo engenanto efana nekholamu ye-tetragonal ngokushiya isibonelelo sokucubungula esimalunga ne-0.4 ukuya kwi-0.6 mm ngokuhambelana nobukhulu bentonga yelaser egqityiweyo.

<2>Ukugaywa okurhabaxa nokucolekileyo kwekholamu: Ikholamu engenanto igaywa ibe yi-tetragonal okanye i-cylindrical cross-section ene-120~180# silicon carbide okanye i-boron carbide abrasives kumatshini wokugaywa orhabaxa, kunye nempazamo ye-taper kunye ne-out-of-roundness ye-±0.01mm.

<3> Ukulungiswa kobuso bokuphela: i-titanium gemstone laser bar icubungula ubuso obuneziphelo ezimbini ngokulandelelana kunye ne-W40, W20, W10 boron carbide grinding end face kwidiski yentsimbi. Kwinkqubo yokugaya, kufuneka kuqwalaselwe ukulinganisa ukuma kobuso bokuphela.

<4> Ukupholisha ngekhemikhali: ukupholisha ngekhemikhali yinkqubo yokupholisha iikristale kwiphedi yokupholisha ngamaconsi esisombululo sokupholisha ngekhemikhali esenziwe kwangaphambili. Ukupholisha i-workpiece kunye nephedi yokupholisha ukuze kushukume kwaye kungqubane, ngelixa kuphando olune-arhente yokupholisha ngekhemikhali (ebizwa ngokuba yi-polishing liquid) ukuze kugqitywe ukupholisha ngoncedo lwe.

<5> Ukugrumba nge-asidi: Iintonga zelitye le-titanium emva kokugrumba njengoko kuchaziwe apha ngasentla zifakwa kumxube we-H2SO4:H3PO4 = 3:1 (v/v), kubushushu obuyi-100-400°C, kwaye zigrumbe nge-asidi imizuzu emi-5-30. Injongo kukususa inkqubo yokugrumba kumphezulu we-laser bar ebangelwa kukonakala komphezulu ongaphantsi komatshini, kunye nokususa iintlobo ngeentlobo zokufaka imibala, ukuze kufumaneke inqanaba le-atom lokuqina kwe-lattice okugudileyo nokuthe tyaba komphezulu ococekileyo.

<6> UNYANGO LOBUSHUSHU BOMPHEZULU: Ukuze kupheliswe ngakumbi uxinzelelo lomphezulu kunye nemikrwelo eveliswe ngenxa yenkqubo yangaphambili kwaye kufunyanwe umphezulu othe tyaba kwinqanaba le-athomu, intonga yelitye le-titanium emva kokugrumba nge-asidi yahlanjwa ngamanzi acocekileyo imizuzu emi-5, kwaye intonga yelitye le-titanium yabekwa kwindawo engqongileyo eyi-1360±20° C. kubushushu obungaguqukiyo beyure e-1 ukuya kwe-3 emoyeni we-hydrogen, kwaye yanyangwa ngobushushu bomphezulu.
