Usoro nhazi elu nke mkpara laser kristal sapphire nke titanium doped

A na-egosi kristal nkume Titanium Ti:Al2O3 (njupụta doping 0.35 wt% Ti2O3), oghere kristal ndị dị na ha dịka eserese usoro nhazi elu nke mkpanaka laser kristal titanium nke ihe mepụtara ugbu a si dị na Fig. 1. Usoro nkwadebe kpọmkwem nke usoro nhazi elu nke mkpanaka laser kristal kristal titanium nke ihe mepụtara ugbu a bụ ndị a:

<1> Ịkpụcha ntụzịaka: a na-ebu ụzọ kpụọ kristal titanium ahụ, wee bee ya n'ime oghere dị ka ogidi tetragonal site n'ịhapụ ikike nhazi nke ihe dị ka 0.4 ruo 0.6 mm dịka nha mkpanaka laser emechara.

<2>Ngweri kọlụm siri ike ma dị mma: A na-akụnye kọlụm ahụ n'ime akụkụ tetragonal ma ọ bụ cylindrical nke nwere ihe nchacha silicon carbide 120 ~ 180 # ma ọ bụ boron carbide n'elu igwe ngweri siri ike, yana njehie na-adịghị mma nke ± 0.01mm.

<3> Nhazi ihu njedebe: titanium gemstone laser bar nke nwere akụkụ abụọ na-ahazi ihu abụọ na-eji W40, W20, W10 boron carbide na-egweri ihu n'elu diski ígwè. N'usoro ngweri, a ga-eleba anya n'ịtụle nha nke ihu njedebe.

<4> Ịchacha kemịkalụ na igwe: Ịchacha kemịkalụ na igwe bụ usoro nke ịchacha kristal na pad polishing na ntapụ nke ihe ngwọta polishing kemịkalụ e mepụtara tupu oge eruo. Ịchacha workpiece na pad polishing maka mmegharị na esemokwu, ebe n'ime slurry nyocha nwere ihe na-eme ka kemịkalụ dị ọcha (a na-akpọ mmiri polishing) iji mezue polishing ahụ site n'enyemaka nke.

<5> Ịchacha ihe e ji achọ mma: A na-etinye mkpanaka nkume titanium mgbe a kpụchara ya dịka akọwara n'elu n'ime ngwakọta nke H2SO4:H3PO4 = 3:1 (v/v), na okpomọkụ nke 100-400°C, ma tinye ya na acid maka nkeji 5-30. Ebumnuche ya bụ iwepụ usoro ịchacha ihe n'elu ogwe laser nke mmebi dị n'okpuru ala mepụtara, ma wepụ ọtụtụ ntụpọ, ka e wee nweta ọkwa atọm nke ịdị ọcha na nke dị larịị, nke dị larịị nke elu dị ọcha.

<6> ỌGWỤGWỌ OKPOMỌKỤ ELU: Iji wepụ nrụgide na ọkọ nke elu ahụ sitere na usoro gara aga ma nweta elu dị larịị na ọkwa atọm, a na-eji mmiri deionized sachaa mkpanaka nkume titanium mgbe emechara ihe mkpuchi acid ruo nkeji ise, a na-etinyekwa mkpanaka nkume titanium n'ebe okpomọkụ dị 1360±20°C. na okpomọkụ na-adịgide adịgide nke awa 1 ruo 3 n'ime ikuku hydrogen, ma tinye ya na ọgwụgwọ okpomọkụ elu.
