Titanium Boride, Kapena TiB2, Ndi Njira Yabwino Yogwiritsira Ntchito Zachipatala

Titanium Boride, kapena TiB2, ndi ceramic yopanda oxide yopanda porosity. Imawonetsanso morphology yabwinobwino ndipo imagwirizana kwambiri ndi biocompatible. Ndizinthu zodula kwambiri, koma ogulitsa akuyesera kuti zichepetse mtengo. Makhalidwe ake apadera amapanga chisankho chabwino kwambiri pazachipatala.

TiB2 ndi ceramic nonoxide

Titanium Boride (TiB2) kapena TiB2 ndi ceramic yopanda oxide yopangidwa kuchokera ku titaniyamu ndi Boron. Ma atomu a titaniyamu amapangitsa kuti zinthu za monoxide zikhale zachitsulo, ndipo ma atomu a boroni amapangitsa kuti zinthu ziziyenda bwino. Mgwirizano wamphamvu pakati pa titaniyamu ndi Boron umapangitsa kuti zinthuzo zikhale zolimba komanso zolimba.

Pali njira zambiri zopangira Titanium Boride (TiB2). Chifukwa cha malo ake osungunuka kwambiri, TiB2 imafuna kutentha kwakukulu panthawi yokonza. Ili ndi anisotropy ya kapangidwe kambewu komwe kamatha kuyambitsa kupsinjika kwamkati komanso kukhazikika kwapang'onopang'ono ikazizira.

Titanium Boride (TiB2) ili ndi malo osungunuka kwambiri ndipo imagonjetsedwa ndi mankhwala ambiri opangira mankhwala. Lilinso wettability kwambiri ndi madutsidwe magetsi. Ndizothandiza pazida zodulira, zida zosavala, komanso zida zankhondo zosagwira. Itha kuphatikizidwanso ndi zitsulo zina zazikulu za oxide kuti zikhale zolimba.

Titanium diboride (TiB2) ndi ceramic yofunikira kwambiri yotentha kwambiri. Kapangidwe kake kapamwamba kwambiri komanso katenthedwe kake kamakhala ndi chidwi chachikulu pazida zomangira, zakuthambo, ndi zida zodulira. Wina wofunika kwambiri wopanda oxide ceramic ndi boron carbide, yomwe ili ndi kukhazikika kwakuthupi komanso kwamankhwala. Amagwiritsidwa ntchito ngati mbale za zida za thupi la munthu, zida zosamva kuvala, ndi zida zoyamwa manyutroni mu zida zanyukiliya.

Titanium Boride (TiB2) ma micron powders amagwiritsidwa ntchito kwambiri pamapangidwe, zida za ceramic sintered, zida zodulira zida, ndi zitsulo zosungunula zachitsulo. Amagwiritsidwanso ntchito popanga zitsulo. Ceramic iyi yopanda okusayidi ndi yolimba kwambiri ndipo imakhala yonyowa kwambiri ikasakanizidwa ndi madzi a aluminiyamu.

Pali njira zambiri zopangira mafilimu oonda a titaniyamu Boride (TiB2) pogwiritsa ntchito njira zosiyanasiyana. Ubwino waukulu wa electroplating ndikuti imatha kupanga magawo 200 ndipo imatha kuphimba mawonekedwe ovuta. Titanium Boride ceramic (TiB2) pakadali pano imangogwiritsidwa ntchito ngati zida za nyutroni kapena zida zolimbana ndi mphamvu.

Imawonetsa morphology yachibadwa

Titanium Boride, gawo lomwe titaniyamu imasakanizidwa ndi Boron, zinthu za halogen, zimatchedwa. Ili ndi mawonekedwe abwinobwino. Itha kupangidwa m'njira ziwiri: ngati chinthu cholimba kapena chopanda kanthu kapena ngati madzi. Titanium monoboride imakhala yolimba kwambiri komanso imakhala ndi dzimbiri komanso yosamva kuvala.

Titaniyamu monoboride imatha kupangidwa pochita titaniyamu ndi gwero la mpweya wa Boron. Boron kuchokera munjira iyi imalowa mu titaniyamu kudzera mu ndevu. Gwero la boron ndi loyera kapena lophatikizidwa ndi activator. Chiyerekezo cha Boron ndi Boron pakuchita izi nthawi zambiri chimakhala chochepera 18 wt %.

Titanium monoboride, chinthu cholimba, chimakhala ndi mawonekedwe a crystalline. Kutentha kwake kwa b-transit ndi 860deg C kwa titaniyamu yamalonda, pamene kutentha kwa b-transit ndi 1010deg C kwa a+b titaniyamu aloyi ndi 6 wt % Al ndi 4 wt % V.

Kafukufuku wa XPS adawonetsa kukhalapo kwa Ni, Fe, ndi B ku NiFeBoride. Nsomba za BO ndi NiFeBx pachimake cha NiFeBoride zinali m'malo omwewo monga zitsanzo zowongolera za NiFe. Zotsatira izi zimathandizira lingaliro la boride kuphatikizidwa mu kapangidwe ka NiFe-Boride.

Makhalidwe a titaniyamu borides amagwirizana kwambiri ndi morphology yawo. Maboridi okhala ndi mawonekedwe opindika ndi ocheperako kuposa owongoka. Chifukwa maatomu a boron amalumikizana mwamphamvu kwambiri ndi ma alloying, samatha kugwedezeka. Ndikotheka kusintha mawonekedwe a pamwamba powonjezera Boron ku titaniyamu alloys.

Titanium boride-based composites amagwiritsidwa ntchito mu implants zamano ndi implants zamankhwala. Kuphatikizikako ndikoyenera kugwiritsa ntchito izi. Komabe, ziyenera kutsimikiziridwa ngati titaniyamu-titanium Boride composites ndi biocompatible. Mu phunziroli, titaniyamu boride composites anapangidwa pogwiritsa ntchito njira zitatu za ufa wazitsulo: spark plasma, vacuum sintering, ndi kutentha kwa isostatic.

Za RBOSCHCO

RBOSCHCO ndi kampani yodalirika padziko lonse yopereka mankhwala ndi kupanga zinthu zopangidwa ndi mankhwala ndipo ili ndi zaka zoposa 12 zokumana nazo popereka mankhwala ndi zinthu zopangidwa ...
