Amanani e-aluminium athrendayo akhuphuka kancane kulo nyaka; nokho-ke, ngalesi sikhathi, amanani asesimweni sesikhathi esifushane eseceleni. Izintela kanye nokukhathazeka kokuhlinzekwa kwempahla kumile futhi kufanele kuqhubeke nokweseka amanani.

Ama-axles angama-Syntace 12mm thru-axles anamabhawudi afakwayo ashaywayo, futhi ngemuva, imicu efanayo esetshenziselwa ukuvikela i-ekseli iphinde ivikele i-derailleur hanger kuhlaka. Wonke amakhebuli namapayipi ahanjiswa ngaphakathi futhi ifreyimu ihambisana nawo wonke amaqoqo akhona manje emakethe. Kunesigxivizo esilula sesihlalo sangaphandle nanjengakwi-UP, futhi i-engeli yeshubhu yesihlalo yakhelwe yazungeza isihlalo sesihlalo esingu-zero-offset esingu-27.2mm. Ubakaki ongezansi we-BB386EVO uhambisana nawo wonke ama-crankset omgwaqo. 

Umshini unezilungiselelo zokuqalisa ze-arc ezizenzakalelayo ze-tungsten engu-3/32-intshi, kodwa uma usebenzisa njalo ububanzi obuhlukile, ungadayela umshini ukuze ulungise i-arc yakho iqala ngendlela othanda ngayo. Ungakwazi futhi ukushintsha i-waveform ye-AC, ukhethe phakathi kwe-Advanced Square, Soft Square, Triangle, ne-Sine Wave. Ngithole ukuthi izilungiselelo ezizenzakalelayo zingisebenzela kahle kakhulu, kodwa ungazama lezi zilungiselelo uma ufuna. I-waveform engunxantathu igcina ukushisa kusezingeni eliphansi kakhulu, ngezinzuzo ezinkulu kakhulu ezibonwa ezinsimbi ezizacile.

Ngenxa yokwanda kokusetshenziswa kwe-aluminium egoqwe ngesicaba embonini yezimoto, ukunikezwa kwensimbi ecishe iqedwe kukhule kwaqina emakethe yase-US. Ukusetshenziswa kwe-aluminium ezimotweni cishe kuzoqhubeka nokwenyuka ngenxa yesidingo sokuthi abakhiqizi bezimoto bazivumelanise namazinga omnotho we-Corporate Average Fuel Economy (CAFE) ka-2025. Eminye imigqa yezimoto eyengeziwe, ikakhulukazi leyo enevolumu enkulu yokuthengisa, ingaguqulela ku-aluminium "imizimba emhlophe." Ngo-2018, iFord Expedition neLincoln Navigator manje zisebenzisa imizimba ye-aluminium.

Sengisebenzise ama-aluminum brazing rod iminyaka futhi ayamangalisa kakhulu ekufakweni okuncane nasekulungiseni.

Q: Nginephrojekthi edinga ukushiselwa okungu-6061-T6 kubo ngokwabo kanye neshidi elingu-6061-T6. Umsabalalisi wendawo yami yokushisela uthi ngingasebenzisa insimbi yokugcwalisa engu-4043 noma engu-5356, kodwa lokhu akuwenzi umqondo kimi. Ingabe i-5356 ayinamandla?

Bese kuba khona abantu abafana nami abane-dc tigged ally abasebenzisa i-flux (hhayi i-solder flux lol flux ye-gas welding ally) futhi banamathele izinduku ze-alu(flux coated) okungcolile kodwa okwenziwe ukuhlanzeka ngokwanele kukhiqiza i-weld eqinile kwisabelomali sobumpofu. Mangisho ukuthi uma usulungiswe kahle ezinye zezinduku ze-aluminium brasing zihlaba umxhwele kakhulu.

Izinga lokushisa nedatha kazibuthe encike endaweni ye-CoL4 iboniswa ku-Fig. 2. Isikhathi sikazibuthe esisebenzayo μeff siqala enanini lika-4.50 μB ekamelweni lokushisa, eliphakeme kakhulu kunevelu ye-spin kuphela ye-S = 3/2 ne-g. = 2.0 (μeff/μB = 3.87) njengomphumela womnikelo obalulekile womfutho we-angular ojikelezayo esimweni esiphansi. I-μeff/μB iqala ukwehla ekupholiseni ngaphansi kuka-30 K ifinyelela inani elingu-3.62 ku-T = 1.9 K, okubangelwa ukuhlukaniswa kwenkundla eyiziro (ZFS). Isenzakalo esifanayo futhi sinesibopho sokuchezuka okukhulu kwamajika kazibuthe we-isothermal akalwe ku-T = 2 no-5 K kufika ku-5 T kusukela kumsebenzi we-Brillouin we-theoretical (Fig. 2). Njengomphumela wezibalo ze-DFT, singacabangela ama-athomu e-Co(II) ahlukaniswe kahle kusuka kwamanye futhi singasebenzisa ngokuphephile i-spin Hamiltonian formalism ye-monomeric complex ukuze sihumushe idatha yokuhlola ye-CoL4 kanje24

Kokubili izinga lokushisa kanye nedatha ye-magnetization encike ensimini yafakwa ngesikhathi esisodwa ngenhloso yokuthola imingcele enengqondo futhi kwatholakala ukuthi ukulingana okwanelisayo kwase kutholakele lapho i-rhombic anisotropy inganakwa. Ngenxa yalokho, amapharamitha afaneleke kakhulu atholwe njenge-g = 2.27, D = -10.1 cm−1 kanye no-χTIP = 5.3 ⋅10−9 m3mol−1 (Fig. 2), lapho χTIP imele umnikelo wokushisa okuzimele i-paramagnetism.24

UWilliamson uthe isifunda songe u-$1.9 million ngokushintsha ezinye zezinto zokwakha zesakhiwo. Uphahla luzoba ngothayela esikhundleni sophahla lwe-aluminium, olulondoloze cishe u-$260,000. Usonkontileka uphinde wavuma ukuyeka ezinye izindleko bese enze umsebenzi wezinsiza esikhundleni sokuqasha usonkontileka omncane.

Iphuzu lesithathu, izindleko zezimali ziphansi unyaka nonyaka ngenxa yemali ephezulu. Isiqondiso sezinga lenzalo yonyaka sihlala singashintshile ku-8.2%, u-8.5% ububanzi njengoba siqondiswe ngaphambili, singaqala ukwehla uma isimo sezinga lenzalo sincipha kancane.

Ukonga ingcindezi nophethiloli, igiya lesihlanu liyakhahlela kusenesikhathi uma kuqhathaniswa, kodwa kusene-oomph eningi kakhulu empompini kangangokuthi le Merc kuma-steroids izofinyelela inani eliphakeme ku-327km/h, okuyiwo wonke ama-axle angu-2.65:1 omfushane avumelayo. Lokho akwanele ukuthi ufanelekele ukuthola iGuinness World Records kodwa kuningi okubonisa ukuthi inesibindi kanye nokubona izinto kusengaphambili lapho iphushelwa umkhawulo.
