Ingabe i-metal foam ihambisana nemvelo?

Igwebu lensimbi liyimpahla engasindi enesakhiwo esinezimbotshana esinikeza izakhiwo eziyingqayizivele ezihlanganisa isilinganiso esiphezulu samandla nesisindo, ukufakwa kwe-thermal kanye nokumuncwa komsindo. Lezi zakhiwo zikwenza kube ukukhetha okukhangayo ezinhlelweni zokusebenza ezisukela kwezezimoto kanye ne-aerospace kuya ekwakhiweni nasekupakisheni. Enye yezinzuzo ezinkulu zemvelo ze-foam yensimbi amandla ayo okunciphisa ukusetshenziswa kwezinto ezibonakalayo kanye nokusetshenziswa kwamandla. Amagwebu ensimbi angafaka isandla kokuningiinqubo yokukhiqiza eqhubekayo futhi enobungani kwemvelongokusebenzisa insimbi encane futhi idinga ukufakwa kwamandla aphansi ngesikhathi sokukhiqiza.

Ngaphezu kwalokho,amagwebu ensimbibabe namandla okwenza ngcono ukusebenza kahle kwamandla ezinhlelweni ezihlukahlukene. Isibonelo, embonini yezimoto, amagwebu ensimbi angasetshenziswa ukuthuthukisa izakhi ezingasindi ezinciphisa ukusetshenziswa kukaphethiloli kanye nokukhishwa kwegesi. Ngaphezu kwalokho, izakhiwo zokushisa ezishisayo ze-foam yensimbi zinomthelela ekongeni amandla ezakhiweni nasezingqalasizinda. Ngokusebenzisa izinsiza ngokuphumelelayo kanye nokunciphisa ukusetshenziswa kwamandla, amagwebu ensimbi anamandla okuba nomthelela omuhle emvelweni kuzo zonke izimboni ezahlukene.

Esinye isici sobungani bemvelo begwebu lensimbi ukugaywa kabusha kwalo. Amagwebu ensimbi amaningi enziwe ngezinto ezigaywa kabusha, futhi isakhiwo sazo esinezimbotshana singahlakazwa kalula futhi siphinde sicutshungulwe. Lokhu kusho ukuthi imikhiqizo yensimbi eyigwebu ingaphinda igaywe kabusha ekupheleni komjikelezo wempilo yayo, kuncishiswe isidingo sezinto ezintsha zokusetshenziswa futhi kuncishiswe imfucuza. Ukuphinda kusetshenziswe kabusha kweigwebu lensimbiinomthelela endleleni yomnotho oyindilinga lapho izinto ziphinde zisetshenziswe futhi zisetshenziswe kabusha, ngaleyo ndlela kuncishiswe umthelela wendawo kanye nokongiwa kwezinsiza.

Ngaphezu kwezakhiwo zayo ezibonakalayo, inqubo yokukhiqiza igwebu lensimbi ingabuye iklanyelwe ukunciphisa umthelela wemvelo. Ubuchwepheshe bokukhiqiza obuthuthukisiwe obufana ne-powder metallurgy kanye nezinqubo zokukhihliza amagwebu zingathuthukiswa ukuze kuncishiswe ukusetshenziswa kwamandla kanye nokuphehla udoti. Ngaphezu kwalokho, ukusetshenziswa kwamandla esimeme kanye namakhemikhali anobungane emvelweni ekukhiqizeni igwebu lensimbi kungathuthukisa ngokwengeziwe ubungane bayo bemvelo. Ngokwamukela izinqubo ezisimeme zokukhiqiza, indawo ezungezile yokukhiqizwa kwegwebu lensimbi ingancishiswa, ikwenze kube ukukhetha kwezinto eziluhlaza.

Sengiphetha, igwebu lensimbi linamandla emvelo ngenxa yaloizinto ezingasindi, ezonga amandla nezigaywa kabusha. Izakhiwo zayo eziyingqayizivele kanye nezinhlelo zokusebenza eziguquguqukayo ziyenza ibe impahla ethembisayo yezimboni ezihlukahlukene ezifuna izixazululo ezisimeme. Njengoba ucwaningo nentuthuko yegwebu lensimbi iqhubeka, ukucatshangelwa kwemvelo kufanele kubekwe phambili ekukhiqizeni nasekusetshenzisweni kwayo. Ngokusebenzisa izinzuzo zemvelo zegwebu lensimbi, izimboni zingafaka isandla ekusaseni elisimeme nelinobungani bemvelo.
