Izinto eziyinhloko zokusika zomshini wokusika we-laser yinsimbi engagqwali, insimbi ye-alloy, insimbi, i-aluminium, i-zinc, i-magnesium nezinye izinto ze-alloy.Izinto ezihlukene zinobulukhuni obuhlukene kanye nobunzima obuhlukene bokusika.Uchwepheshe olandelayoumenzi womshini wokusika we-laserI-Men-Luck ichaza ubunzima bokusika i-laser yensimbi evamile kanye nama-alloys asezingeni eliphezulu.
1. Okubalulekile kunokungahambi kahle kwe-thermal
Lapho umshini wokusika we-laser usika i-alloy, uzokhiqiza ukushisa okukhulu kokusika, okuthwalwa umpompi wangaphambili, futhi ichopho lommese lithwala izinga lokushisa lokusika i-laser lika-700-9000 °.Ngaphansi kwesenzo salokhu kushisa okuphezulu kanye namandla okusika, umkhawulo wokusika uzokhiqiza i-plastic deformation, i-bonding kanye nokugqoka kokusabalalisa.
2. Amandla amakhulu okusika i-laser
Amandla ama-superalloys angaphezulu kuka-30% aphezulu kunalawo ezinsimbi zengxubevange ezivame ukusetshenziswa kuma-steam turbines.Ezingeni lokushisa elingaphezulu kuka-600 ° C, amandla e-nickel-based superalloys asephezulu kunalawo ezinsimbi ezivamile ze-alloy.Amandla okusika amayunithi we-alloy engaqinisiwe yokushisa okuphezulu angaphezulu kuka-3900N/mm2, kuyilapho lawo ensimbi evamile eyingxubevange engu-2400N/mm2 kuphela.
3. Ukuthambekela okukhulu kokusebenza kanzima
Isibonelo, ubulukhuni be-substrate engaqinisiwe ye-GH4169 cishe i-HRC37.Ngemva kokusika ngomshini wokusika i-laser yensimbi, kuzokwakhiwa ungqimba oluqinile olungaba ngu-0.03mm ngaphezulu, futhi ubulukhuni buzokhula bufinyelele cishe ku-HRC47, ngezinga eliqinile elifinyelela ku-27%.Isenzeko sokuqina komsebenzi sinomthelela omkhulu empilweni kampompi enamaphethelo ane-oxidized, ngokuvamile okuholela ekugugeni okuqinile kwemingcele.
Uma sikhuluma ngokuqhathaniswa, izinto ezijwayelekile zingcono ukusika, futhi izinto ezisezingeni eliphezulu ze-alloy ezinobunzima obuphakeme kunzima kakhulu ukuzisika.Izixazululo ezihlukene zokusika kufanele zihlinzekwe ezinkingeni ezihlukene zokusika.Ukuze uthole imibuzo eyengeziwe mayelana nokusika i-laser, sicela uthintane ne-Men-Luckimishini yokusika laserumkhiqizi.
