Ihe njide na-arụ ọrụ dị oke mkpa n'ịhụ na ihe owuwu ahụ ziri ezi n'ofe ụlọ ọrụ dị iche iche, site na ụgbọelu ruo na owuwu. Agbanyeghị, nhọrọ na-ezighi ezi, ntinye, ma ọ bụ ihe ndị metụtara gburugburu ebe obibi nwere ike ibute ọdịda n'oge, na-ebute oke oge nkwụsị na ihe egwu nchekwa. Isiokwu a na-enyocha ihe ndị kacha akpata ọdịda ihe njide ahụ ma na-enye usoro mgbochi iji mee ka ntụkwasị obi dịkwuo elu.
Corrosion: Onye na-egbu nkịtị
Nrụrụaka bụ otu n'ime ihe na-ebute mbibi ngwa ngwa, ọkachasị na gburugburu ebe ọjọọ dị ka mmiri, kemịkalụ, na ngwa ndị dị n'ụsọ osimiri.
| Ụdị nrụrụ | Eme | Ụzọ mgbochi |
|---|---|---|
| Galvanic corrosion | Ọla ndị yiri ya na kọntaktị (dịka ọmụmaatụ, ihe mkpuchi nchara na akụkụ aluminom) | Jiri ọla dakọtara ma ọ bụ ihe nkpuchi mkpuchi |
| Crevice Corrosion | Mmiri tọrọ n'ime oghere (dịka ọmụmaatụ, n'okpuru isi mkpuchi) | Tinye ihe mkpuchi, jiri mkpuchi na-eguzogide corrosion |
| Nchegbu Corrosion Cracking (SCC) | Nchegbu tensile + gburugburu na-emebi emebi | Jiri nickel alloys dị elu (dịka ọmụmaatụ, Inconel), belata nrụgide etinyere |
Ngwọta: Họrọ ihe njide ígwè anaghị agba nchara, titanium, ma ọ bụ nickel alloy maka gburugburu ebe na-emebi emebi.
Ọdịda Ike Ike: Mgbe Nchegbu ugboro ugboro na-akpatara ya nsogbu
Ihe ngwunye etinyere n'ibu cyclic (dịka ọmụmaatụ, n'igwe, ụgbọ ala, ma ọ bụ ụgbọ elu) nwere ike daa n'ihi ike ọgwụgwụ.
| Ihe ịrịba ama ọdịda ike ọgwụgwụ | Atụmatụ Mgbochi |
|---|---|
| mgbawa n'akụkụ mgbọrọgwụ eri | Iji eriri akpọrepu (adịghị ebipụ) maka ndụ ike ọgwụgwụ ka mma |
| Mgbaji na ebe nrụgide | Tee ebugo nke ọma iji belata nrụgide cyclic |
| Ntọhapụ na-aga n'ihu | Iji usoro mkpọchi (dịka ọmụmaatụ, Nord-Lock washers) |
Ngwọta: Họrọ ihe ndị nwere ike dị elu, nke na-anaghị ebelata ike ọgwụgwụ (dịka ọmụmaatụ, titanium nke ọkwa 5, Inconel 718).
Over-Torquing & Under-Torquing
Ịkpachi nke ọma nwere ike ibute ịpụpụ eriri, ịgbatị bolt, ma ọ bụ ịda mbà n'obi.
| Issue | Mmetụta | Prevention |
|---|---|---|
| Over-Torquing | Bolt elongation, eri mebiri | Jiri a ihe mgbawa torque nwere calibrated, soro ndị nrụpụta nkọwapụta |
| N'okpuru Torquing | Ịtọhapụ ịma jijiji, nkewa nkwonkwo | Tee ebugo nke ọma, jiri ogige mkpọchi eri |
Ngwọta: Soro chaatị torque dabere na ihe na mmanụ.
Embrittlement hydrogen (HE)
Ihe na-echegbu onwe ya maka ihe nkedo ígwè dị elu, na atom hydrogen na-ebelata ígwè ahụ.
| Eme | Prevention |
|---|---|
| Electroplating (dịka ọmụmaatụ, bolts nwere zinc) | Ime fasteners post-plating iji wepụ hydrogen |
| Nkpughe na gburugburu acidic | Iji mkpuchi na-abụghị electroplated (dịka ọmụmaatụ, Dacromet) |
Ngwọta: Maka ojiji dị mkpa, jiri mkpuchi na-enweghị hydrogen ma ọ bụ gbanwee gaa na alloys titanium/nickel.
Nhọrọ ihe na-ezighi ezi
Iji ihe nkwụnye na-ezighi ezi maka ngwa ahụ nwere ike ibute ọdịda akaghi aka.
| Ọnọdụ adabaghị | Nhọrọ akwadoro |
|---|---|
| Carbon ígwè n'ime mmiri nnu | Igwe anaghị agba nchara (316) ma ọ bụ titanium |
| Aluminom na oke okpomọkụ | Nickel alloy (Inconel 600) |
| Plastics n'okpuru ibu | Ihe nkwụnye alloy dị elu |
Ngwọta: Lelee chaatị ndakọrịta ihe tupu ị họrọ.
Mmechi: Otu esi agba mbọ hụ na ntụkwasị obi ngwa ngwa
Iji bulie ogologo ndụ ngwa ngwa:
- Họrọ ihe kwesịrị ekwesị Alloys na-eguzogide corrosion maka gburugburu ebe ọjọọ)
- Tinye torque ziri ezi (jiri ngwá ọrụ ahazi, soro nkọwapụta)
- Jiri ụzọ mgbochi atọpụ (ndị na-ekpochi mkpọchi, adhesives)
- Na-enyocha mgbe niile (Lelee maka corrosion, ike ọgwụgwụ mgbawa)
Na TSM Technology , anyị na-enye ihe njide arụmọrụ dị elu na titanium, nickel alloy, na ígwè anaghị agba nchara , na-eme ka ọ sie ike n'ọnọdụ kachasị sie ike.
