Amandla aphezulu ne-ductile izingxenye zensimbi engagqwali ingakhiqizwa

---

Muva nje, iqembu elihlangene lokucwaninga elivela e-University of Birmingham e-United Kingdom, eStockholm University eSweden naseZhejiang University eChina lithuthukise ubuchwepheshe obusha obungenasici be-SLM 3D bokuphrinta ngamandla amakhulu kanye ne-ductility, enqoba amandla nokuthamba kokukhiqiza okwenziwayo. Ibhodlela. Le nqubo ingasetshenziselwa ukwenza izinto ezisindayo embonini ye-aerospace neyezimoto.

Ubuchwepheshe obusha bokukhetha i-laser melting (SLM) obuthuthukiswe yithimba locwaningo buyakwazi ukuphrinta ubujamo obungakaze bube khona, buhlinzeka ngamazinga okupholisa ashesha kakhulu kusuka ku -1000 ° C / s kuya ezigidini eziyi-100 ° C / s, okhiqiza imiphumela efiseleka kakhulu, okwenza 3D insimbi engagqwali ephrintiwe ukumelana kakhulu nabakhiqizi bezimoto nezindiza. Izinga lokupholisa elisheshayo lalobu buchwepheshe, ngaphezu kokukhiqiza okungeziwe, alikakafiki enqubeni yokukhiqiza insimbi, ishiya insimbi isesimweni sokungalingani. Lokhu kungaholela ekwakhiweni kwenethiwekhi engalingani ngobukhulu obukhulu obungakhiqiza izakhiwo ezithandekayo ezinjengamandla nokuqina.
"Lo msebenzi uhlinzekela abacwaningi ngethuluzi elisha lokuqamba izinhlelo ezintsha ze-alloy ezinezici ezingaphezulu kakhulu kwemishini ezisiza ukuphrinta kwe-3D kwensimbi ukungena ezindaweni lapho kudingeka khona izakhiwo eziphakeme zemishini, njengezinto zokwakha emkhakheni we-aerospace nezimoto." UDkt Leifeng Liu, ongumcwaningi e-ABCASH e-University of Birmingham, uthe.

U-Liu nethimba lakhe banomthwalo wemfanelo wokwakha amasistimu okuhlola okubalulekile kwe-nano ngaphakathi kwe-electron microscope ukuze abacwaningi bakwazi ukuhlaziya ukusebenza kwamasampula ensimbi aphrintiwe e-3D ngesikhathi sokuhlolwa komshini. 

Ngokusho kwe-PTJ Shop, lolu hlelo lokuhlola lusiza abacwaningi baqonde lezi zindlela ezibonakalayo futhi banqume izici ezisebenzayo ze-microstructure yezinsimbi eziphrintiwe.

Xhumanisa nale ndatshana: Izingxenye zensimbi engagqwali enamandla aphezulu kanye nezindayo zingakhiqizwa

Isitatimende Esiphrintiwe: Uma ingekho imiyalo ekhethekile, zonke izindatshana ezikulesi sayithi zingokoqobo. Sicela ukhombise umthombo wokuphrinta kabusha: https: //www.cncmachiningptj.com/ ezinthanks！
