Ọnọdụ nke magnesium alloy akpakanamde anwụ mgbatị ụlọ ọrụ
Mpempe ọkụ dị elu nke ụgbọala abawanyela mkpa maka ịkpụ ọkụ dị ka magnesium na aluminom. Kemgbe 1990, magnesium maka ụgbọala na-eto na nkezi mmụba kwa afọ nke 20%. Alloys magnesium abiala ubi di nkpa na mmepe nke teknụzụ ihe akụrụngwa. Die-casting magnesium alloy ihe ndị kwesịrị ekwesị karịsịa maka imegharị ihe maka akụ na ụba, ike ịzọpụta, obere carbon na ọcha mmepụta chọrọ n'ihi na ha recyclability na ala chipless usoro. Ha bụ ndị isi na mmepe nke ụgbọala iji fechaa. Isi ndị na-emepụta akụkụ ụgbọ ala jidesiri ohere nke mmepe ike ma tinye ego na mmepe nke magnesium alloy automotive die castings. Dabere na "China Magnesium Alloy Automotive Die Casting Industry Analysis Report" data, na 2015, China si magnesium alloy automotive anwụ mgbatị ụlọ ọrụ chọrọ ruru 149,000 tọn, mmụba nke 23.12%. Ka ọ dị ugbu a, ụlọ ọrụ ụgbọ ala nke ụlọ na nke mba ọzọ na-arụ ọrụ na ahụ (ihe dị ka 30%), injin (ihe dịka 18%), sistemụ nnyefe (ihe dịka 15%), sistemụ ije (ihe dịka 16%), na wiil (ihe dịka 10%). 5%) Magnesium alloying nke ígwè ma ọ bụ akụkụ aluminom.
N'ihe banyere ojiji nke alloys magnesium alloys emepụtara na China, ikike ahịa nke ụlọ ọrụ ihe ọkụkụ nke magnesium nke China ga-eru tọn 229,000 na 2017, na ikike ahịa ga-erute 660,000 tọn site na 2022, na nkezi kwa afọ na-eto eto nke 23.5%.

Ngwa nke magnesium alloy na ụgbọala lightweighting

Ngwongwo ime ụlọ

Ọ bụ ezie na alloys magnesium enweghị ezigbo mmebi ahụ, nchedo corrosion abụghị isi ihe na-eche maka ịrụpụta ime ụlọ akpakanwụ. Ya mere, a na-ejikarị alloys magnesium eme ihe n'ọtụtụ ebe n'ime ihe owuwu ụgbọ ala, ọkachasị na ogwe aka na usoro nchịkwa. A kọọrọ na ogidi mbụ nke ngwungwu ngwungwu magnesium bụ General Motors nwụrụ na 1961, na-echekwa kilogram 4 nke ihe atụ ma e jiri ya tụnyere otu akụkụ nke zinc alloy die-casting. N'ime afọ iri gara aga ma ọ bụ karịa, iji ogidi magnesium alloy die-casting tooly emeela nnukwu ọganiihu.
Ngwa nke magnesium alloy na oche malitere na Germany na 1990s, tumadi na SL Roadster iji a atọ-ebe oche belt Ọdịdị mere nke magnesium anwụ-mgbatị. Yiri ngwa nke magnesium alloy na akụrụngwa akụrụngwa, n'afọ ndị na-adịbeghị anya, imepụta na imepụta oche nke ejiri magnesium alloy emegogo usoro mmezi dị mkpa. Ọdịdị oche nke nwere magnesium alloy nwere ike ịdị larịị dịka 2mm, nke na-ebelata ibu ahụ nke ukwuu. Ọ bụ ezie na a na-ejikwa ihe ndị ọzọ dị ka ígwè siri ike, aluminom, na ihe ndị mejupụtara, ndị ọkachamara na-ebu amụma na alloys magnesium ga-abụ isi ihe maka oche oche ụgbọala dị fechaa na nke na-efu ọnụ n'ọdịnihu.

Nchekwa onwe

A na-ejedebe alloys Magnesium na ngwa ahụ, mana a na-ejikwa ya na OEM. Mgbe General Motors webatara C-5 Corvette na 1997, ọ jiri nnukwu ụlọ magnesium alloy na-anwụ anwụ. Tụkwasị na nke ahụ, a na-ejikwa alloy magnesium mee ihe n'ime ụlọ a na-agbanwe agbanwe nke na-agbanwe agbanwe na n'elu osisi nke Cadillac XLR Convertible. Ford F -gbọ ala -150 na SUV na-ejikwa ihe ndọtị magnesium dị ka ebe nchekwa ọkụ. Na Europe, Volkswagen na Mercedes-Benz ebutewo ụzọ na ntinye mgbatị alloy magnesium dị mpe na akụkụ ahụ.

Chassis

Ka ọ dị ugbu a, ejirila wiil ma ọ bụ mepụta wiwi magnesium n'ọtụtụ ụgbọ ala na-agba ọsọ ma ọ bụ egwuregwu egwuregwu na-arụ ọrụ dị elu. Kaosiladị, ọnụ ahịa dị elu nke nsogbu magnesium alloy na-egbochi oke ojiji ha na ụgbọ elu ha na-egbochi elu ha.
N'ọdịnihu, mmepụta nke fechaa, ọnụ ala dị ala magnesium alloy chassis components, dị ka ehiwe, engine nkwusioru na akara ogwe aka, ga-adabere kpamkpam na magnesium alloy mgbatị usoro, na e mepụtara na aluminum alloy wiil na Chassis mmiri. Nkedo usoro nwere ike ịga nke ọma etinyere magnesium alloys mgbe mgbanwe. Tụkwasị na nke ahụ, mmepe nke ụgwọ dị ala, nke na-eguzogide corrosion na alloys magnesium ọhụrụ nwere ike ọgwụgwụ na mmetụta dị elu ga-eme ka ojiji nke magnesium alloys mee ngwa ngwa na chassis.

Powertrain

Imirikiti ihe nkedo nke ike, dị ka ngọngọ engine, isi cylinder, okwu nnyefe, pan pan, wdg. Ka ọ dị ugbu a, ụgbọala pikọp na SUV ndị e mepụtara na North America abụwo nnyefe nke ihe ndị magnesium na-enye, Volkswagen na Audi magnesium alloy na-ebunyekwa ọtụtụ na Europe na China.
Ka ọ dị ugbu a, enwere ọganihu dị mma site na nyocha nke dynamometer na ngwanrọ enwetara magnesium, nke pụtara na a ga-eji ọtụtụ ihe ndị ọzọ magnesium mee ihe na sistemụ ike n'ọdịnihu.
Nsogbu ndị gbara ọkpụrụkpụ na nkwalite na ntinye nke alloys magnesium
Uzo na-adighi ike nke corrosion, ugwo onu ahia na onu ahia di elu bu ndi na-ewu ewu na-egbochi alloys magnesium.
Alloys Magnesium enweghi nsogbu nke onu ahia karie nke onwu, onu ahia di elu, na ihe egwu di omimi nke mmeputa. Du Fangci, onye ndụmọdụ China Association of Automobile Manufacturers, kwuru na magnesium bụ ihe na-arụsi ọrụ ike yana nrụrụ corrosion dị ezigbo njọ. China oru ike na corrosion eguzogide nke magnesium alloy akụkụ ka njọ. Na mgbakwunye, magnesium na-adịkarị mfe nsị na mgbawa n'oge nhazi, na enwere nsogbu nrụpụta nchekwa. Saịtị mmepụta chọrọ nlezianya njikwa iji hụ na nchekwa dị mma.
Site na osooso nke mmepe obodo, ike na-adịwanye ụkọ, mmetọ gburugburu ebe obibi na-adịwanye njọ, nchekwa nchekwa ume na mbelata ikuku ewepụtala ihe omume dị mkpa gbasara akụ na ụba mba yana ndụ ndị mmadụ. Carsgbọ ala ọdịnala abụọ na ụgbọ ala ọhụụ ọhụrụ na-elebara anya nke ahụ dị mfe iji nweta nchekwa nchekwa na nchekwa gburugburu ebe obibi.
Ngwongwo Magnesium maka ugboala na-ari elu, usoro magnesium alloy na-anwu anwu na-akawanye nká, usoro ntinye a na-agbasa. Nnukwu akụkụ nke magnesium alloy ịnwụ-mgbatị akụkụ akụkụ ga-akwalite usoro nke ịkọ ụgbọ ala.

Njikọ na akụkọ a ： Nwere ike magnesium alloy ịnwụ castings-ewu ewu na automotive lightweighting?
