Ukwenzela ukuthintela ukupholisa ukuvukela emva komatshini, kwi-jikelele, i-tungsten ye-tungsten kufuneka inyangwe, emva kokuba imilinganiselo, amandla esixhobo aya kuncitshiswa emva kokucaphuka, ubunzima be-carbide ye-carbide ye-carbide ye-carbide ye-carbide ye-carbide ye-carbide ye-carbide ye-calbide ye-carbide ye-carbide ye-carbide ikhule iya kukhula. Ke ngoko, ngenxa ye-carbide yamandla, unyango lobushushu yinkqubo ebaluleke ngakumbi. Namhlanje, umhleli weChiangrui uza kuthetha nawe ngolwazi olufanelekileyo lonyango lwe-vacuum.
Ukulungiswa kunye nokuveliswa konyango lobushushu, kukho iingxaki "ezihlala" imibala "kumphezulu weemveliso ezisetyenzisiweyo. Ukufezekisa impembelelo yokuqhubela phambili kwemveliso eqaqambileyo, engabhalwanga yimveliso yinjongo eqhelekileyo ilandelwa yi-R & D kunye nabasebenzisi bezixhobo ze-vacuum. Ke siyintoni isizathu sokukhanya? Zeziphi izinto ezichaphazelekayo? Ndingayenza njani imveliso yam ekhanyayo? Lo ngumbandela oxhalabisa kakhulu kwiingcali zomgca ongaphambili kwimveliso.
I-coloration ibangelwa yi-oxidation, kwaye imibala eyahlukeneyo ihambelana neqondo lokushisa elivelisiweyo kunye nobungqingqwa befilimu yesidima. Ukucingela i-oyile kwi-1200 ° C kuya kubangela ukuba kubethwa kwaye kunyibilike kumphezulu wengqimba, kwaye iphezulu kakhulu i-vacuum iya kubangela ingqungquthela yokuqina kunye nokuxhuzulwa. Oku kunokubangela ukuqaqamba komphezulu.
Ukuze ufumane umhlaba ongcono, la manyathelo alandelayo kufuneka athathelwe ingqalelo kwaye aqwalaselwe kwimveliso yokuvelisa:
1. Okokuqala, izikhombisi zobugcisa zeziko lezixhobo zevacuum kufuneka zifezekise imigangatho yesizwe.
2. Unyango lwenkqubo kufuneka lube nengqondo kwaye luchaneke.
3. Iziko lezixhobo ze-vacuum akufuneki lingcoliswe.
I-4. Ukuba kukho imfuneko, hlamba iziko ngerhasi ecocekileyo ecocekileyo ngaphambi kokungena nokushiya iziko.
5. Kuya kufuneka ihambe kwi-oven efanelekileyo.
Ukukhetha irhasi ye-InErt (okanye inxalenye ethile yegesi eqinileyo) ngexesha lokupholisa.
Kulula ukufumana indawo entle kwi-vacuum yezithandongo kuba akukho lula kwaye kuyabiza ukufumana imeko yokukhusela enamacala angama-784 ° C. Nangona kunjalo, kulula ukufumana i-vacuum moya enamachaphaza i-dew ilingana ne-74 ° C kunye nomxholo ongaqhelekanga. Ukulungiswa kunye nokuveliswa konyango lwe-vacuum wobushushu, intsimbi engenasinyithi, i-titanium, kunye ne-alloy ephezulu yobushushu banzima. Ukwenzela ukuthintela ingqumbo yezinto, uxinzelelo (vacuum) yesine sensimbi kufuneka ilawulwe kwi-70-130pa.
