Hanyar sarrafa saman na sandunan Laser-doped sapphire crystal

Titanium gemstone lu'ulu'u Ti: Al2O3 (doping maida hankali 0.35 wt% Ti2O3), da crystal blanks wanda aka bisa ga tsari kwarara zane zane na surface aiki hanya na titanium gemstone crystal Laser sanda na yanzu ƙirƙira aka nuna a cikin siffa 1. Takamaiman matakan shirye-shirye na hanyar sarrafa ƙasa na sandar Laser gemstone gemstone crystal na ƙirar yanzu sune kamar haka:

<1> Yanke daidaitawa: kristal na titanium gemstone an fara daidaita shi, sannan a yanka shi cikin wani ginshiƙi mai siffar tetragonal ta barin izinin sarrafawa na kusan 0.4 zuwa 0.6 mm daidai da girman sandar Laser da aka kammala.

<2>Tsarin ginshiƙi mai laushi da niƙa mai kyau: Rukunin blank ɗin yana ƙasa zuwa sashin tetragonal ko cylindrical giciye tare da 120 ~ 180 # silicon carbide ko boron carbide abrasives akan injin niƙa, tare da taper da kuskuren zagaye ± 0.01mm.

<3> Ƙarshen sarrafa fuska: titanium gemstone Laser mashaya biyu ƙarshen fuska aiki jere tare da W40, W20, W10 boron carbide niƙa ƙarshen fuska a kan faifan karfe. A cikin aikin niƙa, ya kamata a biya hankali ga auna ma'auni na ƙarshen fuska.

<4> Chemical-mechanical polishing: Chemical-mechanical polishing shine aiwatar da goge lu'ulu'u akan kushin gogewa tare da digo na maganin etching da aka riga aka tsara. Polishing workpiece da polishing kushin don dangi motsi da gogayya, yayin da a cikin bincike slurry dauke da sinadaran etching wakili (wanda ake kira polishing ruwa) don kammala polishing tare da taimakon.

<5> Acid etching: The titanium gemstone sanduna bayan polishing kamar yadda aka bayyana a sama an saka a cikin cakuda H2SO4: H3PO4 = 3: 1 (v / v), a zazzabi na 100-400 ° C, da acid-etched ga 5. - minti 30. Manufar ita ce don cire tsarin polishing a farfajiyar mashaya ta Laser da aka yi ta hanyar lalacewa na sub-surface na inji, da kuma cire nau'i-nau'i iri-iri, don samun matakin atomic na santsi da lebur, mutuncin lattice na tsabtataccen farfajiya. .

<6> MAGANIN ZAFIN SURFACE: Don ƙara kawar da matsalolin da ke haifar da matsalolin da ke haifarwa saboda tsarin da ya gabata da kuma samun fili mai laushi a matakin atomic, sandar gemstone na titanium bayan etching acid an wanke shi da ruwa mai narkewa na mintuna 5, kuma an sanya sandar gemstone na titanium a cikin wani yanayi na 1360± 20 ° C. a yanayin zafi na 1 zuwa 3 hours a cikin yanayin hydrogen, kuma hõre surface zafi magani.
