Ubuchwepheshe - Isingeniso seZirconia Coatings

I-Zirconia iyimpushana emhlophe esindayo e-amorphous noma ikristalu ye-monoclinic, ayinaphunga, ayinambitheki, cishe ayincibiliki emanzini.Iphuzu lokuncibilika licishe libe ngu-2700℃, elinephuzu eliphezulu lokuncibilika kanye nephuzu elibilayo, ubulukhuni namandla, ekushiseni okujwayelekile njengesivikelo, futhi izinga lokushisa eliphezulu linezakhiwo ezinhle kakhulu ezifana nokuhamba kukagesi.Ngaphezu kwalokho, izakhiwo zamakhemikhali ze-zirconia zizinzile kakhulu, azincibiliki emanzini, i-hydrochloric acid kanye ne-dilute sulfuric acid, inokuqina okuhle kwe-thermochemical, izinga lokushisa eliphezulu conductivity kanye namandla okushisa aphezulu kanye nokuqina, ngesikhathi esifanayo inomshini omuhle, oshisayo, kagesi, izakhiwo ze-optical.

I-Zirconia coating ilungiswa ngokufafaza kwe-plasma, okungenye yezingubo ezivamile ze-ceramic.Ubuchwepheshe bokufafaza i-plasma busebenzisa i-arc ye-plasma eqhutshwa amandla aqondile njengomthombo wokushisa, ukushisa izitsha zobumba, ama-alloys, izinsimbi nezinye izinto ukuze kuncibilike noma kuncibilike kancane, futhi kufafazwe ngesivinini esikhulu ebusweni bomsebenzi owenziwe ngaphambili ukuze kwakhiwe indawo yokunamathela eqinile. ungqimba.Ukufafaza kwe-Plasma ukulungisa i-zirconia coating, izici zayo eziyinhloko zimi kanje:

Ukwazi;

I-1, ukumelana nokushisa okuphezulu: indawo encibilikayo ye-zirconia icishe ibe ngu-2700 ℃, ivamise ukusetshenziswa ezintweni eziphikisayo, ngakho-ke ukunamathela kwe-zirconia kunokumelana okuhle nokushisa okuphezulu.

Ukwazi;

I-2, ukumelana nokugqoka: i-zirconia ceramics inobunzima obukhulu nokumelana nokugqoka okungcono, ubulukhuni bayo be-Mohs bungaba ngu-8.5, nokumelana nokugqokwa okuhle;

I-3.I-Thermal barrier coating: Ukusetshenziswa kwe-plasma yokufafaza i-zirconia thermal barrier coating ezinjini zegesi kuye kwathuthuka kakhulu.Ngokwezinga elithile, liye lasetshenziswa engxenyeni yezinjini zomoya, ezingathuthukisa kakhulu ukuqina kwezingxenye zokushisa okuphezulu.

I-Stainless steel wire mesh ene-Zirconia coating isetshenziswa kabanzi endaweni yokushisa ephezulu yokusebenza.Ukucaciswa okujwayelekile kuno-60mesh/0.15mm kanye no-30mesh/0.25mm.Singakwazi ukwenza i-coating nhlangothi zombili.Lolu hlobo lwempahla futhi lungenza ukumbozwa kwensimbi ye-Nickel mesh.I-zirconia ehlanzekile ephezulu inganikeza ungqimba lokumelana nokushisa okuphezulu. , ukumelana nokugqwala kwezinhlobonhlobo zezinto zokusebenza, ikakhulukazi nge-aluminium, i-molybdenum, iplatinum, i-rhodium ne-titanium lezi.izinto zensimbi ezibophayo zizinzile.Ifaneleka ngokukhethekile ukugqoka phezu kwesici sokushisa sesithando sokushisa esishisayo, esingandisa impilo yayo yesevisi.
