Aluminium Alloy Elu Ọgwụgwọ: 7 Series Aluminum Hard Anodizing

1. Usoro nchịkọta

Hard anodizing na-eji electrolyte kwekọrọ ekwekọ nke alloy (dị ka sulfuric acid, chromic acid, oxalic acid, wdg) dị ka anode, na-eme electrolysis n'okpuru ụfọdụ ọnọdụ na etinyere ugbu a. Ọkpụrụkpụ nke ihe nkiri anodized siri ike bụ 25-150um. A na-ejikarị ihe nkiri anodized siri ike nke nwere ihe nkiri na-erughị 25um maka akụkụ dịka igodo eze na spirals. A chọrọ ọkpụrụkpụ nke ihe nkiri anodized siri ike ka ọ bụrụ 50-80um. Uwe na-eguzogide ma ọ bụ ọkpụrụkpụ nke ihe nkiri anodized maka mkpuchi bụ ihe dịka 50um. N'okpuru ụfọdụ usoro usoro pụrụ iche, a na-achọkwa ka ịmepụta ihe nkiri anodized siri ike nke nwere ihe karịrị 125um. Otú ọ dị, a ghaghị iburu n'obi na ihe nkiri nke anodized na-abawanye ụba, na-ebelata microhardness nke oyi akwa ya, na ọdịdị elu nke ihe nkiri ahụ ga-abawanye.

2. Usoro njirimara

1) The elu hardness nke aluminum alloy mgbe ike anodizing nwere ike iru ihe ruru HV500;

2) Anodic oxide ihe nkiri ọkpụrụkpụ: 25-150 microns;

3) Adhesion siri ike, dị ka njirimara anodizing nke sitere na anodizing siri ike na-emepụta: 50% nke ihe nkiri anodizing na-emepụta na-abanye n'ime aluminum alloy, na 50% na-agbaso n'elu ala nke aluminum alloy (bidirectional growth);

4) Ezigbo mkpuchi: voltaji mmebi nwere ike iru 2000V;

5) Nguzogide dị mma: Maka aluminom alloys na ọdịnaya ọla kọpa nke na-erughị 2%, akara kachasị mma bụ 3.5mg / 1000 rpm. Ndekọ iyi nke alloys ndị ọzọ ekwesịghị gafere 1.5mg/1000 rpm.

6) Na-adịghị egbu egbu na adịghị emerụ ahụ mmadụ. Usoro electrochemical nke ọgwụgwọ ihe nkiri anodizing eji eme ihe na-adịghị njọ, ya mere, maka nchebe gburugburu ebe obibi chọrọ n'ọtụtụ nhazi ígwè ọrụ mmepụta ihe, ụfọdụ ngwaahịa na-eji aluminom anodized siri ike kama nke igwe anaghị agba nchara, ịgbasa omenala, plating chromium siri ike na usoro ndị ọzọ.

3. Ngwa ngwa

Ike anodizing bụ tumadi adabara ebe na-achọ elu eyi iguzogide, okpomọkụ iguzogide, na mma mkpuchi Njirimara nke aluminum na aluminum alloy akụkụ. Dị ka cylinders dị iche iche, pistons, valves, cylinder liners, bearings, cargo compartments, tilt stick and guide rails, hydraulic equipment, uzuoku impellers, mma flatbed igwe, gia na buffers, wdg omenala electroplating nke siri ike chromium nwere àgwà nke ala ala. na-eri, ma ntụpọ nke a film bụ na mgbe film ọkpụrụkpụ bụ nnukwu, ọ na-emetụta ndidi nke n'ibu ike ọgwụgwụ ike nke aluminum na aluminum alloys.
