Itekhnoloji -Intshayelelo yeZirconia Coatings

I-Zirconia ngumgubo omhlophe onzima we-amorphous okanye ikristale ye-monoclinic, ayinavumba, ayinancasa, phantse ayinyibiliki emanzini.Indawo yokunyibilika imalunga ne-2700℃, enendawo ephezulu yokunyibilika kunye nenqanaba lokubilisa, ubulukhuni kunye nokomelela, kubushushu obuqhelekileyo njengesigqubuthelo, kunye nobushushu obuphezulu buneempawu ezibalaseleyo ezifana nokuhamba kombane.Ukongeza, iipropathi zeekhemikhali ze-zirconia zizinzile kakhulu, azinyibiliki emanzini, i-hydrochloric acid kunye ne-dilute sulfuric acid, inozinzo oluhle lwe-thermochemical, i-conductivity yobushushu obuphezulu kunye namandla aphezulu obushushu kunye nokuqina, kwangaxeshanye inomatshini olungileyo, i-thermal, umbane, iimpawu ezibonakalayo.

I-Zirconia yokugqoka ilungiselelwe ngokutshiza i-plasma, enye yezinto eziqhelekileyo zokugqoka i-ceramic.Itekhnoloji yokutshiza iPlasma isebenzisa i-arc yeplasma eqhutywa ngumbane othe ngqo njengomthombo wobushushu, ukufudumeza iiseramikhi, ialloyi, isinyithi kunye nezinye izinto ezinyibilikayo okanye ezinyibilikisiweyo, kunye nokutshiza ngesantya esiphezulu ukuya kumphezulu womsebenzi owenziwe ngaphambili ukwenza indawo yokuncamathela eqinileyo. umaleko.Ukutshiza ngePlasma ukulungiselela ukugquma kwe-zirconia, iimpawu zayo eziphambili zezi zilandelayo:

Kwazi uku;

I-1, ukumelana nobushushu obuphezulu: indawo yokunyibilika i-zirconia imalunga ne-2700 ℃, ihlala isetyenziswa kwizixhobo ezichasayo, ke i-zirconia yokwambathisa inokumelana nobushushu obuphezulu.

Kwazi uku;

I-2, ukuxhathisa ukunxiba: iiceramics ze-zirconia zinobunzima obukhulu kunye nokumelana nokunxiba okungcono, ubulukhuni bayo be-Mohs bumalunga ne-8.5, kunye nokumelana nokunxiba kakuhle;

I-3.I-Thermal barrier coating: Ukusetyenziswa kwe-plasma yokutshiza i-zirconia thermal barrier coating kwii-injini zegesi yenze inkqubela phambili enkulu.Ukuya kumlinganiselo othile, isetyenziswe kwi-injini ye-injini ye-injini yegesi, enokuthi iphucule ngokubonakalayo ukuqina kwamacandelo aphezulu obushushu.

Umnatha wocingo lwensimbi engenasici kunye ne-Zirconia yokwambathisa isetyenziswa ngokubanzi kwindawo yokusebenza yobushushu obuphezulu.Iimpawu eziqhelekileyo zine-60mesh / 0.15mm kunye ne-30mesh / 0.25mm.Sinokwenza i-coating kumacala omabini.Olu hlobo lwezinto eziphathekayo nalo lunokwenza i-coating kwi-mesh yensimbi ye-Nickel.I-zirconia ecocekileyo yokucoca i-zirconia inokubonelela ngomgangatho wokumelana nobushushu obuphezulu. , ukuxhathisa umhlwa kwiintlobo ngeentlobo zezixhobo zokusebenza, ngakumbi nge-aluminium, i-molybdenum, iplatinam, i-rhodium kunye ne-titanium ezi.izinto zetsimbi ezidibanisa zizinzile ngakumbi.Kufanelekile ngokukodwa ukugquma kwindawo yokufudumeza yesithando somlilo esiphezulu, esinokwandisa ubomi benkonzo.
