Ọrụ nke ọgwụgwọ okpomọkụ nke aluminom bụ imeziwanye ihe eji arụ ọrụ nke ihe, wepụ nchekasị fọdụrụnụ ma melite ígwè ọrụ nke ọla. Dị ka ebumnuche dị iche iche nke ọgwụgwọ okpomọkụ si dị, enwere ike kewaa usoro ahụ ụzọ abụọ: ọgwụgwọ preheat na ọgwụgwọ okpomọkụ ikpeazụ.
Ebumnuche nke ọgwụgwọ preheat bụ iji melite arụmọrụ nhazi, wepụ nrụgide dị n'ime ma kwadebe ezigbo metallographic nhazi maka ọgwụgwọ okpomọkụ ikpeazụ. Usoro ọgwụgwọ okpomọkụ ya gụnyere annealing, normalizing, ịka nká, quenching na tempering na ihe ndị ọzọ.
1) Annealing na normalizing
A na-eji annealing na normalizing maka ihe na-ekpo ọkụ na-arụ ọrụ nke aluminom. Carbon ígwè na alloy ígwè nwere carbon ihe karịrị 0.5% na-na-emekarị annealed iji belata ha ike siri ike na mfe ịkpụ; A na-eji ígwè carbon na alloy ígwè nwere ihe na-erughị 0.5% iji zere ịrapara na mma mgbe ike dị oke ala. Na-eji normalizing ọgwụgwọ. Annealing na normalizing ka nwere ike nụchaa ọka na edo Ọdịdị, na-akwadebe maka ụdi okpomọkụ ọgwụgwọ. A na-ahazikarị mkpochapụ na imeziwanye ihe mgbe emechara oghere ahụ na tupu arụ ọrụ siri ike.
2) ọgwụgwọ ịka nká
A na-eji ọgwụgwọ ịka nká eme ihe n'ụzọ bụ isi iji wepụ nrụgide dị n'ime ahụ na-ebute n'ichepụta na ígwè ọrụ efu.
Iji zere oke ọrụ ụgbọ njem, maka akụkụ ndị nwere nkenke zuru oke, ọ ga-ezuru ịhazi otu ọgwụgwọ ịka nká tupu emechaa. Otú ọ dị, maka akụkụ ndị nwere ezigbo ihe achọrọ, dị ka igbe nke jig na-agwụ ike, wdg, ekwesịrị ịhazi usoro ọgwụgwọ abụọ ma ọ bụ ọtụtụ ịka nká. Akụkụ dị mfe n'ozuzu anaghị achọ ọgwụgwọ ịka nká.
Na mgbakwunye na nkedo, maka ụfọdụ akụkụ ziri ezi nke na-adịghị mma, dị ka nkenke nkenke, iji wepụ nrụgide dị n'ime ahụ na-emepụta n'oge nhazi ma mee ka nhazi nhazi nke akụkụ ahụ guzosie ike, a na-ahazi ọtụtụ ọgwụgwọ ịka nká n'etiti machining siri ike na ọkara imecha. Maka akụkụ ụfọdụ nke ogwe osisi, a ghaghị ịhazi ọgwụgwọ ịka nká mgbe usoro nhazi ahụ gasịrị.
3) Ịkwụsị na iwe ọkụ
quenching na tempering na-ezo aka elu okpomọkụ tempering mgbe quenching. Ọ nwere ike nweta otu ụdị sorbite na-ewe iwe, nke bụ nkwadebe maka ibelata nrụrụ n'oge nkwụsị elu na ọgwụgwọ nitriding. Ya mere, quenching na tempering nwekwara ike iji dị ka a preheat ọgwụgwọ.
N'ihi na mma keukwu n'ibu Njirimara nke quenching na tempering akụkụ, ọ nwekwara ike-eji dị ka ikpeazụ okpomọkụ ọgwụgwọ usoro n'ihi na akụkụ ụfọdụ na-adịghị achọ elu ike ike na-eyi iguzogide.
Ebumnuche nke ọgwụgwọ okpomọkụ ikpeazụ bụ imeziwanye ihe ndị na-emepụta ihe dị ka ike siri ike, eyi nguzogide na ike. Usoro ọgwụgwọ okpomọkụ ya gụnyere quenching, carburizing na quenching, na ọgwụgwọ nitriding.
1) Ịkwụsị
A na-ekewa Quenching ka ọ bụrụ nkwụsị elu na ikpochapụ n'ozuzu ya. N'ime ha, elu quenching na-ọtụtụ ebe-eji n'ihi na ya obere deformation, ọxịdashọn na decarburization, na n'elu quenching nwekwara uru nke elu mpụga ike na ezi eyi iguzogide, mgbe ịnọgide na-enwe ezi esịtidem siri ike na ike mmetụta iguzogide. Iji melite n'ibu Njirimara nke elu quenching akụkụ, okpomọkụ ọgwụgwọ dị ka quenching na tempering ma ọ bụ normalizing na-achọkarị dị ka a tupu okpomọkụ ọgwụgwọ. Ụzọ usoro ya n'ozuzu ya bụ: ịgbapụ, ịghagharị, normalize, annealing, machining siri ike, quenching na tempering, ọkara imecha, elu quenching, finishing.
2) Carburizing na quenching
Carburizing na quenching bụ ịbawanye carbon ọdịnaya nke elu oyi akwa nke akụkụ mbụ, na mgbe quenching, elu oyi akwa na-enweta elu hardness, mgbe isi akụkụ ka na-ejigide a ụfọdụ ike na elu siri ike na plasticity. A na-ekewa Carburizing n'ime n'ozuzu carburizing na akụkụ carburizing. Mgbe a na-eme carburizing akụkụ, a ga-emerịrị ihe mgbochi seepage maka akụkụ ndị na-abụghị nke carburizing. Ebe ọ bụ na carburizing na quenching kpatara nnukwu nrụrụ, na carburizing omimi bụ n'ozuzu n'etiti 0.5 na 2 mm, a na-ahazi usoro nhazi n'etiti ọkara na njedebe.
Ụzọ usoro a na-abụkarị: ịgbapụta, ịhịa aka n'ahụ, normalizing, machining siri ike, ọkara imecha, carburizing na quenching, imecha. Mgbe akụkụ ndị na-abụghị nke carburized na-eme ka akụkụ nke carburizing na quenching na-anabata usoro usoro nke iwepụ ihe mkpuchi nke oke oyiri mgbe ọ na-abawanye oke, a ga-edozi usoro nke wepụ ihe mkpuchi nke oyi akwa carburized mgbe ị na-ekpochapụ na quenching, tupu quenching.
3) ọgwụgwọ nitriding
Nitriding bụ usoro nke itinye nitrogen atom n'ime elu igwe iji nweta oyi akwa nke ogige nwere nitrogen. Ngwunye nitriding nwere ike imezi ike ike, na-eyi nguzogide, ike ike ọgwụgwụ na nguzogide corrosion nke elu akụkụ ahụ. Ebe ọ bụ na okpomọkụ ọgwụgwọ nitriding dị ala, nrụrụ ahụ dị ntakịrị, na oyi akwa nitriding dị gịrịgịrị, n'ozuzu ọ dịghị ihe karịrị 0.6 ~ 0.7mm, a ghaghị ịhazi usoro nitriding ka oge na-aga. Iji belata nrụrụ n'oge nitriding, ọ na-ewekarị iwe ọkụ dị elu maka enyemaka nchekasị.
