Ngokwengxelo yamva nje yePhysicist Organisation Network, iinjineli zeYunivesithi yaseCalifornia, eLos Angeles, ziye zasebenzisa i-titanium carbide nanoparticles ukwenza ialluminiyam ekhethekileyo yealloy AA7075, engenako ukudityaniswa ibe yi welded.Imveliso ephumayo kulindeleke ukuba isetyenziswe kwimveliso yeemoto kunye namanye amacandelo ukwenza iindawo zayo zibe khaphukhaphu, zisebenzise amandla ngakumbi, kwaye zihlale ziqinile.
Amandla angcono e-alloy ye-aluminium eqhelekileyo yi-alloy ye-7075.Iphantse yomelele njengentsimbi, kodwa inobunzima besinye kwisithathu kuphela sentsimbi.Isetyenziswa ngokuqhelekileyo kwiindawo zomatshini we-CNC, i-aircraft fuselage kunye namaphiko, iigobolondo ze-smartphone kunye ne-rock climbing carabiner, njl njl. Nangona kunjalo, ii-alloys ezinjalo zinzima ukudibanisa, kwaye ngokukodwa, azikwazi ukuthungwa ngendlela esetyenziselwa ukuveliswa kweemoto, ngaloo ndlela zibenza zingasebenzi. .Oku kungenxa yokuba xa i-alloy ishushu ngexesha lenkqubo ye-welding, i-molecular structure ibangela ukuba izinto ezidibeneyo ze-aluminium, i-zinc, i-magnesium kunye nobhedu zihambe ngokungalingani, okukhokelela ekuqhekekeni kwemveliso edibeneyo.

Ngoku, iinjineli ze-UCLA zifake i-titanium carbide nanoparticles kwi-wire ye-AA7075, ivumela ezi nanoparticles ukuba zisebenze njenge-filler phakathi kwezixhumi.Ukusebenzisa le ndlela entsha, i-welded joint eveliswayo inamandla okunyamezela ukuya kwi-392 MPa.Ngokwahlukileyo koko, i-AA6061 i-aluminium alloy welded joints, esetyenziswa kakhulu kwinqwelomoya kunye neendawo zemoto, inamandla okuqina angama-186 MPa kuphela.

Ngokutsho kophononongo, unyango lobushushu emva kwe-welding inokunyusa amandla e-tensile ye-AA7075 edibeneyo ukuya kwi-551 MPa, efaniswa nentsimbi.Uphando olutsha luye lwabonisa ukuba iingcingo zokugcwalisa zizalisweTiC titanium carbide nanoparticleszinokudityaniswa ngokulula ngakumbi kwezinye iintsimbi kunye nengxubevange yentsimbi ekunzima ukuyidibanisa.

Oyena mntu uphethe olu phando uthe: “Kulindeleke ukuba obu bugcisa butsha benze le ngxubevange yokuqina kwe-aluminiyam isetyenziswe ngokubanzi kwiimveliso ezinokuveliswa ngomlinganiselo omkhulu, njengeemoto okanye iibhayisekile.Iinkampani zinokusebenzisa iinkqubo ezifanayo kunye nezixhobo esele zinazo.I-alloy ye-aluminiyam eyomelele kakhulu idityaniswe kwinkqubo yokwenziwa kwayo ukuyenza ibe khaphukhaphu kwaye isebenzise amandla ngakumbi ngelixa igcina amandla ayo. "Abaphandi basebenze nomenzi webhayisekile ukusebenzisa le ngxubevange kwimizimba yeebhayisekile.
