Nhọrọ ọgwụgwọ dị n'elu bụ nsogbu nke na-aga ihu ihu. E nwere ọtụtụ ụdị nhọrọ mgbanwe elu elu, na onye na-emebe elu ekwesịghị ịdị na-atụle na akụnụba nke imewe, mana a toa ntị na usoro mgbakọ na usoro gburugburu ebe obibi. N'okpuru ebe a bụ okwu dị mkpirikpi ụfọdụ ndị na-ejikarị colounds nke na-ejikarị ụkpụrụ ndị a dị n'elu, maka ndị na-eme Fastener.
1. Electrogalvanizing
Zinc bụ ihe mkpuchi kachasị eji eme ihe maka ngwa ahịa azụmahịa. Ọnụahịa ahụ dịtụ ọnụ ala, ọdịdị dịkwa mma. Agba ndị a na-akpọkarị ojii na ndị agha. Agbanyeghị, arụmọrụ mgbochi ya dị nkezi, arụmọrụ mgbochi ya bụ nke kacha ala n'etiti asụsụ zinc (mkpuchi) n'ígwé. A na - ejikarị ule na - anọpụ iche nke ga - anọ awa 72, a na - ejikwa ndị nnọchi anya pụrụ iche na - emekwa na ule na - adịghị ọcha na - adịgide ruo ihe karịrị 200 awa. Agbanyeghị, ọnụahịa ahụ dị oke ọnụ, nke bụ ugboro 5-8 nke okporo osisi na-acha uhie uhie.
Usoro electrogalvanizing bụ pronogen embrittlement, yabụ bolts dị n'elu klas nke 109. Ọ bụ ezie na enwere ike iwepụ hydrogen site na iji oven mgbe ịchasịrị, ihe nkiri onye na-eme ka ọ ghara imebi ihe dị elu karịa 60 ℃, yabụ iwepụ Hydrogen ga-rụrụ mgbe electropịa na tupu ịjụ. Nke a nwere ezigbo ọrụ na ụgwọ ọrụ dị elu. N'ezie, osisi na-emepụta ihe anaghị ewepụ hydrogen ma ọ bụrụ na ndị ahịa akọwapụtara.
Ngbanwe dị n'etiti Torque na iji ike dị egwu nke Galvanized Fasteners dara ogbenye, na-ejikọghịkwa ha maka ijikọ akụkụ dị mkpa. Iji meziwanye nhatandị nke torque, usoro nke mkpuchi na-ekpuchi bekee mgbe enwere ike iji meziwanye ma kwalite nguzobe nke toque preged.
2. Phosphait
Principleskpụrụ dị mkpa bụ na phosphptating dị ọnụ ala karịa ịga ụka, mana nguzogide ya na-emegide ya dị njọ karịa ịga na-agagharị. Mgbe proofph, mmanụ kwesịrị itinye ya, na iguzogide ya na arụmọrụ nke mmanụ etinyere. Dịka ọmụmaatụ, mgbe proopph, na-etinye mmanụ nsị nchara nchara ma na-eduzi ule na-anọpụ iche nke na-anọpụ iche maka naanị awa 10-20. Itinye mmanụ dị elu na-achọgharị ike nwere ike iru 72-96 awa. Ma ọnụ ahịa ya bụ ugboro abụọ nke General Phosphain.
E nwere ụdị fospphing abụọ a na-ejikarị maka Fasteners, Fosspphpph Throppphy na phosppppphpphy na nke a na-eme ngwa ngwa Zince. Phosphing Zinc sitere na phosphing nke Zinciation karịa phosphing na-adabere, na phosppppppppption dabere na-eguzogide na-eguzogide ma na-eyi ntugide karịa. Enwere ike iji ya na okpomọkụ site na 85 ruo 400 degrees fahrenheit (107-204 ℃). Karịsịa maka njikọ nke ụfọdụ ihe dị mkpa. Dị ka ijikọ rod bolts na mkpụrụ nke injin, isi cylinder, isi ihe, na-efe efe, wiil na-acha odo odo na mkpụrụ, wdg.
Ihe dị elu na-eji phosph, nke nwekwara ike izere nsogbu embrogen. Ya mere, bolts dị n'elu ọkwa 10.9 na ụlọ ọrụ mmepụta ihe na-eji ọgwụgwọ ọkụ.
3. Oxiding (Blasting)
Blading + mmanụ bụ mkpuchi a ma ama maka ụlọ ọrụ mmepụta ihe n'ihi na ọ bụ ọnụ ala ma na-adị mma tupu oriri mmanụ. N'ihi blachaning ya, ọ nwere ihe fọrọ nke nta ka ọ bụrụ ikike mgbochi mgbochi, yabụ na ọ ga-ekpu ngwa ngwa na-enweghị mmanụ. Ọbụnadị na ọnụnọ mmanụ, ule nnu mmiri nnu nwere ike ị ga - anọ naanị awa 3-5.
4. Akụkụ Electroplation
Cadmium na-atụpụta nguzogide iguzogide nguzogide, ọkachasị na gburugburu mmiri nke mmiri mmiri, ma e jiri ya tụnyere ọgwụgwọ ndị ọzọ dị elu. Ọgwụ mmiri na-emebi ihe mkpofu cadmium dị elu, ọnụahịa ya bụ ihe dị ka ugboro 15-20 nke electroplating Zinc. N'ihi ya, anaghị eji ya na ụlọ ọrụ izugbe, naanị maka iche iche. Ndị na-eme ngwa ngwa ejiri ụgbọ elu nke ọla.
5. Pịa chromium
The chromium mkpuchi bụ ihe kwụsiri ike na ikuku, ọ dịghị mfe ịgbanwe agba ma hapụ ya ka ọ ghara imegide ya, nweekwa obi ike na ezigbo iyi egwu. A na-ejikarị ya iji chepụta chromium na-eji ngwa ngwa maka ebumnuche ịchọ mma. A na-ejikarị ya n'ubi mmepụta ihe dị elu nke nwere ihe ndị dị elu corrosion dị elu, dị ka ezigbo chrome dị ezigbo ọnụ ahịa dị ka igwe anaghị agba nchara. Naanị mgbe ike igwe anaghị agba nchara ezughi oke, chrome pleated Fasteners na-eji kama.
Iji gbochie corrosion, ọla kọpa na nickel kwesịrị ibu ụzọ chekwaa tupu ịkọwa Chrome. Igwe mkpuchi chromium nwere ike iguzogide oke okpomọkụ nke 1200 degrees fahrenheit (650 ℃). Mana enwere nsogbu nke ihe eji eme ihe hydrogen, yiri electrogalvanizizizi.
6. NIckel
Nke kachasị eji na mpaghara chọrọ ma mgbochi mgbochi na ezi omume. Dịka ọmụmaatụ, ọnụnọ batrị nke batrị ụgbọ.
7. Na-acha odo odo
Na-ekpo ọkụ mipvanizing bụ mkpuchi ikuku na-enweghị ọkụ nke zinc na-efe efe na mmiri. Ọkpụrụkpụ mkpuchi dị n'agbata 15 na 100 μ m. Ọ dịghịkwa mfe ịchịkwa, mana enwere nguzogide iguzogide na-eguzogide na nke injinịa. N'oge usoro ị na-ekpo ọkụ, enwere mmetọ siri ike, gụnyere Zinc Deful na zinc.
N'ihi oke mkpuchi, o meela ihe isi ike n'ịchọgharị na eri dị n'ime na nke mpụga na Fasteners. N'ihi ọnọdụ okpomọkụ nke nhazi nke na-ekpo ọkụ na-ekpo ọkụ, enweghị ike iji ya maka fasteners karịa ogo 10.9 (340 ~ 500 ℃).
8. Zinc infultration
Zinc infultration bụ ụdị ọkụ ọkụ metalllution na-ekpuchi mkpuchi nke zinc. Uwe ya dị mma, a ga-enweta akwa a na-eji enwekarị eriri na abụọ na oghere ndị ìsì. Playgwọ ọkpụrụkpụ bụ 10-110 μ m. Enwere ike ịchịkwa njehie ahụ na 10%. Ike ya na mgbochi mgbochi corrosion arụmọrụ na mkpụrụ bụ ihe kachasị mma na comesings cothings (dị ka electrogalvainizizi, na-acha odo odo na Dacromet). Usoro nhazi ya bụ mmetọ na-enweghị mmerụ na omume enyi.
9.. Dacromet
Enweghị mbipụta Entrogen Hydrogen, na Toque Preload Mmemme na-arụ ọrụ dị mma nke ukwuu. N'echeghị okwu Chromium na gburugburu ebe obibi, dacromet bụ n'ezie ihe kachasị mma maka ike ike dị elu na mkpa mgbochi mgbochi corrin chọrọ.
