Ukugqitywa koMphezulu kwiiNdawo zeMetal ezinesitampu: Isikhokelo esiGqibeleleyo

Ukugqitywa komphezulu owuchazayo kwinxalenye yentsimbi enesitampu kuchaphazela ukuxhathisa kwayo, ukuhanjiswa kombane, inkangeleko, kunye neendleko zizonke - rhoqo nge-15-40% yexabiso lenxalenye. Ukukhetha ukugqiba okungalunganga kuthetha ukungaphumeleli kwentsimi kwangaphambi kwexesha, iingxaki zokuncamathelisa ipeyinti, okanye iindleko ezingeyomfuneko. Kwi- Izahlulo zeMetal isitampu, ukhetho lokugqiba umphezulu ngomnye wemibuzo yokuqala ephakanyiswa liqela lethu lobunjineli ngexesha lophononongo lweDFM, kuba lunempembelelo kuyilo lokufa, ukukhetha izinto, kunye nesicwangciso sosuku olunye lwesibini.

Esi sikhokelo sigubungela zonke iindlela zokugqiba umphezulu wezixhobo zetsimbi ezinesitampu - i-electroplating, iiconversion coatings, i-organic-coatings, i-organic-coatings, kunye noluhlu lwe-organic-coatings, kunye nokukhethwa kweendleko. iindlela zokunceda iinjineli kunye nabathengi benze ukhetho olufanelekileyo.

Ukugqiba kobuso lubhekiselele kulo naliphi na icandelo lonyango elisetyenzisiweyo emva kokulungiswa komgangatho wesitampu emva kokulungiswa kwesakhiwo sesitampu emva kokulungiswa kwesitampu. ukumelana nokunxiba, ukuguquguquka kombane, ukuthengiseka, okanye ukubonakala okubonakalayo.

Kutheni uMphezulu uQeda iMiba yezahlulo ezinesitampu

Uwukhetha njani uMphezulu oLungileyo Gqiba

Ukukhetha umphezulu wokugqiba kuxhomekeke kwizinto ezine: okusingqongileyo, umsebenzi, imathiriyeli kunye nohlahlo lwabiwo-mali. Itheyibhile engezantsi ithelekisa ezona zikhetho zixhaphakileyo:

Isakhelo seSigqibo sokuKhetha

Sebenzisa lo mthi isigqibo ekhawulezayo ukwenzela izicelo eziqhelekileyo isitampu inxalenye:

• isibiyeli sentsimbi, ukusetyenziswa kwangaphandle → i-zinc plating + chromate okanye umgubo wokugquma
• I-aluminiyam ebiyelweyo, i-elektroniki → anodizing (Uhlobo II) uguqulo
• Ubhedu / ubhedu terminal yombane → ukucakwa ngenkcenkce okanye igolide yokubeka ukuthembeka okuphezulu
• Inxalenye yentsimbi, inkangeleko yezithambiso → umgubo wokugquma (ohambelana nombala)
• Steel isibiyeli, ukusetyenziswa kwangaphandle → electropolishing
• intwasahlobo yomjikelo ophezulu okanye ikliphu → shot peening + zinc plating
• Ubhedu / ubhedu terminal yombane yezonyango / 341529 S32129 S32129 intsimbi yonyango → oxide emnyama okanye ipleyiti yezinc (ebhityileyo)

ImiGangatho yokuGqiba kunye neMigangatho

Ngalo lonke ixesha ubhekisa kwimigangatho esebenzayo xa ukhankanya ukugqitywa komphezulu kwimizobo yobunjineli. Eyona migangatho isetyenziswa kakhulu kwiindawo ezinesitampu ibandakanya:

Xa ubhala iicallouts kwimizobo, landela ifomathi eqhelekileyo. Umzekelo: ASTM B633 Fe / Zn 8, SC2 (ichromate ecacileyo) ichaza i-zinc plating eyi-8 µm ubukhulu kunye nonyango olongezelelweyo lwechromate kukhuseleko lokuthotywa okuphakathi.

Iindleko Ukuthelekiswa koMphezulu ogqityiweyo

ixabiso lokugqiba umphezulu lixhomekeke kubungakanani benxalenye, umthamo webhetshi, kunye nobunzima benkqubo. Apha ngezantsi luthelekiso lweendleko olusekwe kumalungu anesitampu esinomthamo ophezulu (amaqhekeza ali-10,000+):

• indleko ye-$ 0.: i-oxide emnyama, iphosphate, ukuguqulwa kwechromate - izinto ezincinci kunye namandla
• Iindleko eziPhakathi ($0.03–0.15/inxalenye): i-zinc plating, i-tin plating, i-e-coating - iinkqubo eziqhelekileyo ze-electrochemical
• Iindleko eziphezulu ($0.10–0.50/inxalenye): i-nickel plating, i-powder coating, i-anodizing - i-coatings enzima, amaxesha omjikelo omde
• iindleko zePremium ($5.0.050): i-chrome enzima, i-gold plating, i-electropolishing - isinyithi esixabisekileyo okanye iinkqubo eziyinkimbinkimbi

Ingcebiso yokonga iindleko: Kwi- Izahlulo zeMetal isitampu, sihlala sincoma ukudibanisa ukugqitywa - umzekelo, i-zinc plating + ukuguqulwa kwe-chromate inikeza i-80% yokukhusela ukubola kwe-powder coating kwi-30% yeendleko. Xoxa ngeemfuno zesicelo sakho kunye neqela lethu lobunjineli ngexesha le-DFM ukuze uchonge olona kugqiba lungabizi kakhulu.

Imibuzo Ebuzwa Rhoqo

Yintoni eyona ndawo ixhaphakileyo yokugqiba isitampu sentsimbi?

I-Zinc electroplating ene-chromate conversion yeyona nto ichazwe ngokubanzi kwi-carbon steel iindawo ezinesitampu. Inika ukhuseleko lokutya kwedini (iiyure ezingama-96-500 zetyuwa ngokuxhomekeke kuhlobo lwechromate), ixabisa i-$0.02-0.08 ngenxalenye encinci, kwaye ine-2-3 yeentsuku zokukhokela. I-ASTM B633 Fe/Zn 8 enechromate ecacileyo okanye etyheli igubungela uninzi lwezicelo zezibiyeli zemizi-mveliso kunye nezithuthi.

I-powder powder ithelekisa njani ne-e-coating yeendawo ezinesitampu?

Ukugquma kwePowder kunika ukhuseleko olungqingqwa (60–120 µm vs 15–35 µm), ukhetho lombala olungasikelwanga mda, kunye nokumelana okungcono kwe-UV, kuyenza ilunge kumalungu abonakalayo angaphandle. I-E-coating ibonelela ngokhuselo oluphezulu lweemilo ezintsonkothileyo kunye nemingxuma yangaphakathi ngexabiso eliphantsi ngenxalenye nganye, iyenza ikhethelwe amacandelo omzimba wemoto. Kwiindawo ezinomgangatho ofihlakeleyo okanye ukunyamezela okuqinileyo, ifilimu encinci ye-e-coating kunye ne-uniform deposition idla ngokuyenza ibe yinto engcono kakhulu.

Ngaba ndingenza i-anodize iindawo ezinesitampu sentsimbi?

No. I-Anodizing isebenza kuphela kwi-aluminium, i-titanium, kunye ne-magnesium alloys. Kwiindawo zentsimbi ezifuna ukuxhathisa okufanayo kwe-corrosion kunye nobunzima, qwalasela i-zinc-nickel alloy plating (ASTM B841) okanye iingubo ze-zinc flake (Dacromet / Geomet). Ezi zibonelela ngokukhuselwa ngokuthelekiswa ne-aluminium anodized kwiinkqubo ezihambelana nentsimbi. I-

Ngowuphi umphezulu ogqibeleleyo olungele izihlanganisi zombane?

I-tin plating (2.5–5.0 µm matte tin ngaphezulu kwe-1.0–2.0 µm nickel) ngumgangatho wezona ziqhagamshelo zombane ezithengiswayo, ezibonelela ngokuthengiswa kunye ne-10–15 mΩ ukuxhathisa ukudibana. Kwiinkqubo zokhuseleko lweemoto (i-airbag, i-ADAS) efuna i-zero-failure intembeko kwiminyaka eyi-15, khankanya i-gold-over-nickel (0.5–1.25 µm igolide eqinileyo nge-ASTM B488). I-Phosphor bronze okanye i-beryllium isiseko sobhedu kunye ne-tin plating igubungela i-90% yezicelo zokudibanisa.

Ndiyithintela njani i-hydrogen embrittlement ngexesha lokutyalwa?

Amacandelo ensimbi ephezulu (UTS> 1000 MPa, ubunzima> 40 HRC) iyakwazi ukuxutywa kwe-hydrogen ngexesha lokunyuswa kwe-asidi kunye ne-electroplating. Amanyathelo okuthintela abandakanya: (1) ukubhaka kwi-190-210 ° C kwiiyure ze-4-23 ngaphakathi kweyure ye-1 yokucoca (nge-ASTM B850), (2) ukusebenzisa iibhafu ze-alkaline ze-zinc endaweni ye-asidi zinc, (3) ukucacisa ukucoca ngoomatshini endaweni yokukhetha i-asidi xa kunokwenzeka, kunye (4) nokunciphisa ubuninzi be-plating. Ngalo lonke ixesha wazisa umthengisi wakho weplating ngobulukhuni be-substrate.

Leliphi ixesha eliqhelekileyo lokukhokelela kukugqiba iindawo ezinesitampu?

Iingubo ezilula zokuguqula (i-oxide emnyama, i-chromate, i-phosphate) ifuna iintsuku ezi-1-2. I-Electroplating (i-zinc, i-tin, i-nickel) ithatha iintsuku ezi-2-5. Ukugquma umgubo kunye ne-anodizing kufuna iintsuku ezi-3-7 kubandakanya ixesha lokunyanga. I-complex multi-layer finishes (i-chrome yokuhlobisa phezu kwe-nickel phezu kobhedu) inokuthatha iintsuku ezi-7-10. KwiiNdawo zeMetal isitampu, silungelelanisa ukugqiba iishedyuli kunye nemveliso ukunqanda ukongeza ixesha lokuhamba kuhambiso lwakho.

Ukuqukumbela

Ukukhetha kokugqiba umphezulu sisigqibo esibalulekileyo sobunjineli esichaphazela ukusebenza, ukubonakala, kunye neendleko.
