Iirivethi zakuqala zazizikhonkwane ezincinci ezenziwe ngomthi okanye ngethambo.Umzimba wokuqala wokuguqula isinyithi unokuba ngukhokho weerivets esizaziyo.Akukho mathandabuzo ukuba iindlela zakudala uqhagamshelo metal eyaziwayo eluntwini, nto leyo enokulandelwa emva ekuqaleni ukusetyenziswa kwentsimbi enyibilikayo.Umzekelo, ngeBronze Age, amaJiphutha ajija aqhobosha kwaye aqhoboshela imizimba emithandathu yeefeni yeplanga yomgca wangaphandle wevili elifakweyo kunye neerivethi.Emva kokuba amaGrike aphumelele ngempumelelo imifanekiso eqingqiweyo emikhulu ngobhedu, adibanisa iindawo kunye neerivets.Okwangoku, kukho iintlobo ezininzi zophuhliso lwe-rivet, ngakumbi kuphuhliso lwamashishini ahlukeneyo.
"Iinxalenye ezisemgangathweni zentsimbi" yingcamango yegama elithile elibandakanya uluhlu olubanzi lweemveliso.Amalungu asemgangathweni wensimbi engenasici ahlala esetyenziselwa ukuqinisa iindawo zoomatshini ezibiza kakhulu ngenxa yobuhle bazo, ukuqina, ukuxhathisa okuqinileyo kunye nezinye iimpawu.Ngenkqubela phambili yoluntu, iimfuno eziphakamileyo nazo zibekwe phambili kwiindawo ezisemgangathweni zensimbi engenasici.Amalungu asemgangathweni ensimbi engenasici aphinde abhekisele kwizikhonkwane zensimbi ezingenasici, ezizikhonkwane eziqhelekileyo.Inkcazo, imilinganiselo kunye noluhlu lokunyamezela yonke imigangatho yelizwe.
Iinxalenye ezisemgangathweni zensimbi ezingenasici zineemfuno zazo zezinto zokuvelisa.Uninzi lwezixhobo zensimbi ezingenasici zinokwenziwa zibe ziingcingo zentsimbi okanye imivalo yokuvelisa i-fastener, kubandakanywa i-austenitic stainless steel, i-ferritic stainless steel, i-martensitic stainless steel kunye nemvula eyenza lukhuni intsimbi.Ngoko ke yeyiphi imigaqo xa ukhetha izinto?Ukukhethwa kwezinto zensimbi ezingenasici kuqwalaselwa ikakhulu kule miba ilandelayo:
1. Iimfuno kwiipropati zomatshini, ngakumbiamandla ezinto zokubopha;
2. Iimfuno zeemeko zokusebenza kwiukumelana nokugqwala kwezinto;
3. Iimfuno zokushisa okusebenzayo ekuxhathiseni ukushisa (amandla aphezulu okushisa, ukumelana ne-oxidation) yezinto;
4. Iimfuno zokusebenza kokulungiswa kwezinto ngokubhekiselele kwiteknoloji yokuvelisa;
5. Ezinye izinto, ezifana nobunzima, ixabiso kunye nokuthengwa, kufuneka ziqwalaselwe.
