Molo, yiza kudibana neendaba zethu!

Ukuqaliswa kwamantongomane ensimbi engenasici.

Umgaqo osebenzayo we-nut yensimbi engenasici kukusebenzisa i-friction phakathi kwentsimbi yensimbi engenasici kunye nebholithi yokuzivalela. Nangona kunjalo, ukuzinza koku kuzitshixa phantsi kwemithwalo eguquguqukayo kuyancipha. Kwezinye iimeko eziphambili, siya kuthatha amanyathelo okuqinisa ukuqinisekisa ukuzinza kwe-stainless steel nut clamping. Phakathi kwabo, ukubethelela i-nut yensimbi engenasici yenye yemilinganiselo yokuqinisa.
Enyanisweni, abantu abayiqondayo i-chemistry baye baphumelela: zonke isinyithi zivelisa iifilimu ze-oxide kumphezulu we-O2 emoyeni. Ngelishwa, i-compounds eyenziwe kwi-carbon steel steel iyaqhubeka i-oxidize, ivumela i-corrosion yande kwaye ekugqibeleni yenze imingxuma. Ipeyinti okanye i-oxidation-resistant metals ezifana ne-zinc, nickel, kunye ne-chromium zingasetyenziselwa i-electroplating ukuqinisekisa ukugqitywa kwentsimbi ye-carbon. Nangona kunjalo, njengoko sisazi, olu londolozo luyifilimu encinci kuphela. Ukuba umaleko okhuselayo wonakaliswe, intsimbi engaphantsi iqala ukurusa. Ukuxhatshazwa kwe-corrosion yensimbi engenasici kuxhomekeke kwi-chromium, kodwa ekubeni i-chromium yenye yezinto zentsimbi, iindlela zokulondoloza zahlukile.
Ngenxa yokuba insimbi engenasici kunye ne-carbon steel zihluke kakhulu. Insimbi engenasici ine-ductility elungileyo. Ukusetyenziswa ngokungafanelekanga kunokukhokelela ngokulula kwizikrufu zentsimbi ezingenasici ezingenakukhutshwa emva kokuba zidibene. Ngokuqhelekileyo kwaziwa ngokuthi "ukutshixa" okanye "ukuluma". Ke ngoko, ezi ngongoma zilandelayo kufuneka ziqwalaselwe xa usebenzisa:
(1) I-nut kufuneka ijikelezwe ngokuthe ngqo kwi-axis ye-screw ukuphepha ukuthambeka;
(2) Ngexesha lenkqubo yokuqinisa, amandla kufuneka alingane, kwaye amandla kufuneka angagqithisi i-torque ekhuselekileyo (ngetafile ekhuselekileyo ye-torque)
(3) Zama ukusebenzisa isikrufu samandla okuxova okanye isikrufu sosokethi, kwaye uphephe ukusebenzisa isikrufu esilungelelanisiweyo okanye isikrufu sombane;
