Namuhla sixoxa nge-electro-spark deposition's apply kuma-alloys ensimbi , ngesikhathi esifanayo sizogxila kulobu buchwepheshe ukuthi singasishintsha kanjani isikhunta kumathuluzi okubumba umjovo kanye nokubunjwa kokuphonsa.
Iyini i-Electro-Spark Deposition?
Ukwelashwa kwe-Electro-spark, okubuye kwaziwe ngokuthi yi-Electro-discharge machining (EDM), kuyinqubo yokukhiqiza ekhethekile ebandakanya ukusetshenziswa kokukhishwa kukagesi ukuze kumiswe futhi kulungiswe indawo engaphezulu yezingxenye zensimbi.
Ngesikhathi sokwelashwa kwe-Electro-spark, ukukhishwa kukagesi kukhiqizwa phakathi kwe-electrode kanye nomsebenzi, ngokuvamile owenziwe ngezinto zokuhambisa ezifana nensimbi noma ama-alloys.Inqubo iqala ngokubeka i-electrode, ngokuvamile ngendlela yethuluzi elincane, elibunjiwe, eduze nendawo yokusebenza.
Lapho i-voltage isetshenziswa phakathi kwe-electrode kanye ne-workpiece, uchungechunge lokukhishwa kukagesi okusheshayo kwenzeka.Lokhu kuphuma kudala ukushisa okukhulu, kuncibilikisa izingxenye ezincane zobuso bomsebenzi.Insimbi encibilikisiwe ibe isicinywa ngokushesha uketshezi lwe-dielectric, okuyenza iqine futhi yakhe ama-crater amancane noma ama-indent.
I-ESD isetshenziswa kuma-alloys ensimbi
Lapho amandla e-capacitor ekhululwa, i-current eqondile idala i-arc ye-plasma ephezulu yokushisa phakathi kwethiphu ye-electrode kanye ne-workpiece ye-alloy yensimbi.Leli banga eliphezulu lokushisa liphakathi kuka-8000 no-25000°C.I-arc ye-plasma i-ionize i-anode futhi isheshe idlulisele into encibilikisiwe ku-workpiece.
Le anode ye-ionizing idluliselwa ku-substrate ngama-pulses amafushane.I-arc yokushisa ephezulu iqukethe izinhlayiya ze-anode, umfudlana wokushisa (ijethi elishisayo), kanye ne-plasma edalwe ukubola kwamagesi nama-athomu asebenzayo e-nitrogen, umoya-mpilo, nekhabhoni.Ukushisa okuningi kuthuthwa amajethi ashisayo kanye ne-plasma.
Ngenxa yokuthi ama-pulses mafushane, ukudluliswa kokushisa nge-jet eshisayo namanye amagesi kuncane, futhi okuwukuphela kokudluliselwa kokushisa ku-substrate ngenani elincane lezinhlayiya ze-anode ezifakwe ku-substrate.Ngakho-ke, lawa ma-pulses adlulisela ukushisa okuncane ku-substrate ngaphandle kokushintsha i-microstructure ye-substrate.Le ndlela inenzuzo kakhulu kunenqubo yokushisela okuhlanganisiwe evame ukusetshenziselwa ukulungisa ama-alloys anezindawo ezithinteke kakhulu ekushiseni (isb., ukuqina okuphansi, ubulukhuni obuphezulu, ukuqhekeka kwe-liquefaction).
Ukwengeza, inqubo isiza ukudala isibopho esiqinile se-metallurgical phakathi kwe-substrate ne-coating.I-Microalloying phakathi kwe-electrode melt kanye ne-substrate iqala ukwakheka kwe-plasma ngokubola komoya, ama-carbonates, ama-carbides nama-nitrides.
Izinzuzo
1.Ukunemba Nokunemba: Ukwelashwa kwe-Electro-spark kuvumela ukubunjwa okunembayo nokunembile kwemininingwane eyinkimbinkimbi kanye namakhonco ayinkimbinkimbi ezindaweni zensimbi.Ukukhishwa kukagesi okulawulwayo kuguguleka okokusebenza ngendlela elawulwayo, okuvumela ukudalwa kwezici ezinembayo njengezimbobo ezincane, izikhala, noma ama-indent anonemba ophezulu wokunemba.
2.Ukugcinwa Kobuqotho Bempahla: Enye yezinzuzo ezibalulekile zokwelashwa kwe-Electro-spark yikhono layo lokulondoloza ubulukhuni nobuqotho bomsebenzi.Ngokungafani nezindlela zemishini ezivamile ezingadala ukushisa okudlulele futhi zenze izinguquko ezingafuneki ezicini ezibonakalayo, ukwelashwa kwe-Electro-spark kunciphisa izindawo ezithinteke ukushisa futhi kugcine ubulukhuni bengcezu yokusebenza nobuqotho besakhiwo.
3.Amajiyometri Ayinkimbinkimbi: Ukwelashwa kwe-Electro-spark kuvumela ukwenziwa kwejometri eyinkimbinkimbi okungenzeka kube inselele noma okungenzeki ukuyifeza ngezindlela ezijwayelekile zokuwenza.Ikhono layo lokubumba izici eziyinkimbinkimbi livumela ukukhiqizwa kwesikhunta, i-dies, noma ezinye izingxenye ezine-contour eyingqayizivele nemininingwane eyinkimbinkimbi, ukwandisa amathuba omklamo.
I-4.Akukho Ukugqokwa Kwethuluzi: Ngokungafani nezindlela zemishini zendabuko ezibandakanya ukusika noma ukuhuzuka, ukwelashwa kwe-Electro-spark akubandakanyi ukuthintana okuqondile phakathi kwethuluzi nesiqeshana sokusebenza.Ngenxa yalokho, kukhona ukuguga okuncane kwamathuluzi, okuholela ekuphileni kwamathuluzi okwandisiwe kanye nezindleko zokunakekela ezincishisiwe.
Isifinyezo
Lesi sihloko sethula ngokuyinhloko inqubo ye-EDM ekwenzeni isikhunta, hhayi nje ukwethula ukugeleza kwenqubo yayo, kodwa futhi yethula izinzuzo eziyinhloko zale nqubo.Ngevidiyo engenhla, ngithemba ukuthi ungayiqonda inqubo ngokucacile.Uma uneminye imibuzo, sicela ukhululekeXhumana nathi.
