X-Ray Diffraction
Inomiririra akaturikidzana eiyo Xray diffraction data pane pristine uye yakaderedzwa samples yeMetal (kuruboshwe) uye Ceramic (Kurudyi).
Iyo ceramic centre post cartridges, sezvakafanotaurwa nevanyori, yakaramba ichienderana maererano nemakemikari anoumbwa (hapana chiratidzo chekuora kana shanduko yemakemikari pa300 ° C uye 600 ° C).Pane zvinopesana sampuli yesimbi inosangana nekuchinja kwakajeka kwekuumbwa.
Sezvinogona kuonwa neiyo XRD data, iyo ceramic samples inoratidza kutendeseka kwechimiro chekuenderana kuumbwa.Ichi chiratidzo chekusachinja kwechimiro chekristaro sezvo kusimba uye nzvimbo dzepamusoro dzendege dzinosiyana dzinoramba dzakafanana.Tichishandisa rietveld kunatsa, tinoona patani yedu yeXRD yakakurumbira chikamu chetetragonal icho chinonzi chine (101) ndege.
Iyo data yeXRD inoratidzawo kuti pane diki monoclinic chimiro chinotanga kusimuka che600 ° C sampu nekuda kwe (111) ndege iri pazasi angle 2θ.Mukuverenga iyo mol% kubva kune yakapihwa huremu% (compositional data yakapihwa neWonder Garden), zvakaonekwa kuti Zirconia sample is 3 mol% Yttria doped Zirconia.Kana tichienzanisa iyo XRD pateni kune chikamu dhayagiramu tinoona kuti data rakaunganidzwa kubva kuXRD rinoenderana nezvikamu zviripo muchikamu dhayagiramu.Mhedzisiro kubva kune yedu XRD data inoratidza kuti Zirconia chinhu chakanyanya kugadzikana uye chisingashande mune idzi tembiricha mazinga.

■ Tafura 1 - Kuumbwa kweCeramic Centerpost
Kubva paiyo XRD data, zvakaonekwa kuti simbi yesimbi ndeye Brass.Kune iyo yakanyanya tembiricha yekushandisa, inogona kuve sarudzo yenguva dzose asi sezvakaonekwa, kushatisa kunoitika nekukurumidza zvakanyanya zvichienzaniswa neceramic centre-post.Sezvinoonekwa muchirongwa pa600 ° C (yekutanga zano kuruboshwe-kuruboshwe), zvinhu zvinochinja zvakanyanya.Pakona yakaderera 2θ, tinotenda kuti mitsva mitsva inokonzerwa nekuumbwa kweZnO (Zinc Oxide).Pa 300 ° C yemuenzaniso wendarira (kuruboshwe XRD plot) tinoona kuti hapana shanduko yakawanda yakaitika mukuenzanisa nepristine sample.Sample yakaramba iri muchimiro chakanaka chemuviri uye chemakemikari, ichikweretesa kune kugadzikana kwezvinhu kubva mukamuri tembiricha kusvika 300 ° C.
