Atomizer yeUpfu hweSimbi yeGoridhe yeSirivha yeCopper Alloys

Kuchine zvakawanda zvisina kujeka mukunzwisisa tekinoroji yekudhinda ye3D mune zvese zviri muindasitiri yekugadzira yeChina. Tichitarisa mamiriro chaiwo ebudiriro, kusvika pari zvino kudhinda kwe3D hakusati kwasvika pakukura kwemaindasitiri, kubva pamidziyo kusvika kune zvigadzirwa kusvika kumasevhisi achiri muchikamu che "advanced toy". Zvisinei, kubva kuhurumende kusvika kumabhizinesi muChina, mikana yekuvandudzwa kwetekinoroji yekudhinda ye3D inowanzo zivikanwa, uye hurumende nenharaunda vanowanzo tarisa kukanganiswa kwetekinoroji yemidziyo yekudhinda ye3D mune ramangwana pakugadzira, hupfumi, uye mamodheru ekugadzira aripo munyika yangu.

Sekureva kwedata reongororo, parizvino, kuda kwenyika yangu tekinoroji yekudhinda ye3D hakusi pamidziyo, asi kunoratidzwa mumhando dzakasiyana dzezvinhu zvinoshandiswa pakudhinda ye3D uye kudiwa kwemabasa ekugadzirisa mabhizinesi. Vatengi vemaindasitiri ndivo vanotanga kutenga michina yekudhinda ye3D munyika yangu. Midziyo yavanotenga inonyanya kushandiswa mundege, ndege, zvigadzirwa zvemagetsi, kutakura, dhizaini, hunyanzvi hwetsika nedzimwe indasitiri. Parizvino, kugona kwakaiswa kwe3D printers mumabhizinesi eChina kuri kutenderera mazana mashanu, uye mwero wekukura kwegore negore uri kutenderera makumi matanhatu muzana. Kunyangwe zvakadaro, saizi yemusika iripo parizvino inongova mamiriyoni zana eyuan pagore. Kuda kweR&D nekugadzirwa kwezvinhu zvekudhinda zve3D kwasvika anenge bhiriyoni imwe yeyuan pagore. Nekufarirwa uye kufambira mberi kwetekinoroji yemidziyo, chiyero chichakura nekukurumidza. Panguva imwecheteyo, masevhisi ekugadzirisa ane chekuita nekudhinda kwe3D akakurumbira zvikuru, uye vamiririri vazhinji ve3D printing Kambani yemidziyo yakakura kwazvo mukuita kwe laser sintering uye kushandiswa kwemidziyo, uye inogona kupa masevhisi ekugadzirisa ekunze. Sezvo mutengo wemuchina mumwe chete uchiwanzopfuura mamiriyoni mashanu eyuan, kugamuchirwa kwemusika hakuna kukwira, asi sevhisi yekugadzirisa michina yemakambani inozivikanwa zvikuru.

Zvizhinji zvezvinhu zvinoshandiswa mumichina ye3D printing metal atomization pulverizing yemunyika yangu zvinopihwa zvakananga nevagadziri veprototyping vanokurumidza, uye zvinhu zvechitatu hazvisati zvashandiswa, zvichikonzera mitengo yakakwira yezvinhu. Panguva imwe chete, hapana tsvakurudzo yakaitwa pakugadzira hupfu hwakatsaurirwa ku3D printing muChina, uye pane zvinodiwa zvakasimba pakugoverwa kwehukuru hwezvidimbu uye huwandu hweokisijeni. Mamwe mayuniti anoshandisa hupfu hwespray hwakajairika panzvimbo pezvo, husina zvakawanda zvinobvira.

Kugadzira nekugadzira zvinhu zvakasiyana-siyana ndicho chinhu chikuru chekufambira mberi kwetekinoroji. Kugadzirisa mashandiro ebasa uye mitengo yezvinhu kuchasimudzira zviri nani kukura kwetekinoroji yeprototyping inokurumidza muChina. Parizvino, zvinhu zvakawanda zvinoshandiswa mutekinoroji yeprototyping inokurumidza yekudhinda ye3D munyika yangu zvinofanirwa kutengwa kubva kunze kwenyika, kana kuti vagadziri vemidziyo vakashandisa simba rakawanda nemari kuti vagadzire zvinhu izvi, izvo zvinodhura, zvichikonzera kuwedzera kwemitengo yekugadzira, nepo zvinhu zvinoshandiswa mumuchina uyu zvisina simba rakawanda uye kunyatsojeka. . Kuwanikwa kwezvinhu zvekudhinda zve3D kwakakosha.

Upfu hweTitanium neTitanium alloy kana hupfu hweSuperalloy hwakavakirwa paNickel neCobalt hune oxygen shoma, saizi yezvidimbu zvidiki uye sphericity yakakwira hunodiwa. Hukuru hwezvidimbu zveUpfu hunonyanya kuva -500 mesh, huwandu hweokisijeni hunofanira kunge hwakaderera pane 0.1%, uye saizi yezvidimbu zvakafanana. Parizvino, hupfu hwemhando yepamusoro uye michina yekugadzira ichiri kuvimba zvakanyanya nekutenga zvinhu zvinotengeswa kunze kwenyika. Munyika dzekunze, zvinhu zvakagadzirwa nemidziyo zvinowanzounganidzwa uye kutengeswa kuti zviwane purofiti yakawanda. Semuenzaniso, tichitora hupfu hwakavakirwa paNickel, mutengo wezvinhu zvakagadzirwa ungangoita 200 yuan/kg, mutengo wezvigadzirwa zvemumba unowanzova 300-400 yuan/kg, uye mutengo wehupfu hunotengeswa kunze kwenyika unowanzova kupfuura 800 yuan/kg.

Semuenzaniso, simba uye kuchinjika kwekugadzirwa kwehupfu, zvinhu zvinosanganisirwa uye hunhu hwepanyama pane matekinoroji ane chekuita nemidziyo ye3D printing metal atomization powder milling. Saka, tichifunga nezvezvinodiwa zvekushandiswa kwe oxygen shoma uye hupfu hwe fine particle size, zvichiri kudikanwa kuita basa rekutsvagisa rakadai sekugadzira titanium ne titanium alloy powder, gas atomization powder milling technology ye fine particle size powder, uye simba rehupfu pakushanda kwechigadzirwa. Nekuda kwekuganhurirwa kwetekinoroji yekugaya muChina, zvakaoma kugadzirira fine-grained powder parizvino, goho rehupfu rakaderera, uye huwandu hweokisijeni nezvimwe tsvina hwakakwira. Munguva yekushandisa, mamiriro ekunyunguduka kwehupfu anowanzo kuve asina kuenzana, zvichikonzera huwandu hwakawanda hwe oxide inclusions uye zvigadzirwa zvakawandisa muchigadzirwa. Matambudziko makuru ehupfu hwe alloy hwemumba ari mumhando yechigadzirwa uye kugadzikana kwe batch, kusanganisira: ① kugadzikana kwezvikamu zvehupfu (huwandu hwezvinhu zvinosanganisirwa, kufanana kwezvikamu); ② Kugadzikana kwemuviri kwehupfu (kugoverwa kwehukuru hwezvikamu, chimiro chehupfu, kuyerera, loose ratio, nezvimwewo); ③ dambudziko regoho (goho diki rehupfu muchikamu chidiki chehukuru hwezvimedu), nezvimwewo.
