Boron nitrideIlungele ukwahlulela okuhlukahlukene kwezinsimbi zensimbi zensimbi ngenxa yokumelana kwayo okuhlukile okushisayo kanye nokuphikiswa okuphezulu kwamakhemikhali ngokumelene neningi lama-molten izinsimbi. Inzuzo eyengeziwe yeBoron NITride ngama-ceramics ajwayelekile ukulula ukufakwa kwemishini kube yibumba eliyinkimbinkimbi lokubonisa okusheshayo.
Insimbi encibilikisiwe igeleza ngokuqhubekayo isikhunta saziwa ngokuthi ukuphonsa okuqhubekayo. Insimbi encibilikisiwe bese iqinisa ubude obuqhubekayo. Le nqubo ihloselwe ukudala imikhiqizo yensimbi efana nama-slabs, ama-bullts, kanye nemishayo ngamanani amakhulu anezingxenye ezinqamula ezingaguquki. Inqubo eqhubekayo yokuphonsa iqala ngokuncibilika kwensimbi, okuthelwa kamuva kubumba opholile amanzi. Insimbi iqinile kepha isatholakala njengoba isuka kubumba. Lokhu kukwenza ukwazi ukuthi kubunjwe ezingxenyeni ezinde ngaphandle kokuphazamisa inqubo yokusakaza.
Ukuphonsa okuqhubekayo kunikeza izinzuzo eziningi. Inika izinga eliphakeme lokuzenzakalela, elinciphisa iphutha lomuntu futhi linciphise izindleko zabasebenzi. Ukuphonsa okuqhubekayo nakho kusebenza ngempumelelo, njengoba kwenza ukuthi:
Izimboni ezidinga inani elinamandla le-geometries ejwayelekile lilungele kahle ukuphonswa okuqhubekayo. Lokhu kufaka phakathi izimboni zokwakha nezimoto, lapho isidingo semishayo kanye nama-slabs siguquguquki futhi sikhulu.
Inqubo yokuphonsa izinsimbi, kungaba ngefomu labo elihlanzekile noma elenzelwe, lifaka ukudluliswa kwezinsimbi ezibunjiweyo zibe ngamafomu okufa kwangaphambi kokulungiswa. Ukuqinisekisa ukuguquguquka kwenqubo, ukukhiqiza, kanye nokusebenza kahle, kuyadingeka ukwandisa izimo zenqubo ngokuya ngamazinga okushisa, ama-allyling stom, kanye ne-geometry yezakhi.
Lapho usebenzisa ukuphonsa okuhlukahlukene okuqhubekayo nokubumba okuqondile kokuphonsa ukukhiqiza ukwakheka okuhle kwensimbi, kunezinto eziningi eziguqukayo zokuhlola. Ikhwalithi yomkhiqizo wokugcina ingathonywa impahla ye-cast, efana nensimbi noma i-ceramic. Abakhiqizi kumele bahlaziye ukuthi izinto ezibonakalayo zizokhombisa iziphambeko noma ukusabela ekunwetshisweni okushisayo.
Boron nitrideinikeza ikhambi elifanele, kungaba ngesimo sezakhi ezine-minced noma uma isetshenziswa kwifomu le-liquid ukudala aboron nitridecoating surface.Izindawo eziphakeme zokukhishwa kweboron nitrideVikela ama-slurry kanye nama-oxides alo kusuka ekunamatheleni ngaphandle kwalapho, kunjalo, kungenzeka ukuthi uthuthukise umkhiqizo wokuphonsa.
Ku-Metal Casting Izicelo,boron nitrideukhombise ukusebenza okuhle, ikakhulukazi ekuphonzweni okuqhubekayo. Phula izindandatho, into yesikhashana phakathi kwezindawo ezishisayo nezipholile zomugqa wokuphonsa oqhubekayo, zenziwa kusuka ku-poron nitride ceramics eshibhile eyenziwe ngomshini. Lesi yisinyathelo esibalulekile kodwa esabe siyilahla njalo kwinqubo yokuphonsa. I-Melt kumele ikwazi ukudlula kwindandatho yekhefu nasendaweni yokuqina ngaphandle kokulandela. Kufanele futhi ukwazi ukubekezelela izinguquko zokushisa ngokweqile. Ukwehluleka kwe-Ring ukwehluleka kungabiza kakhulu. Ngalesi sizathu, izinto zokwakha ezinama-coefficients aphansi ezingqubuzanayo nokumelana okuqinile okushisayo okushisayo kuphelele.BNmuhle kakhulu kulo mkhakha.
