Laser cladding rudzi rutsva rwekugadzira tekinoroji. Iyo tekinoroji yepamusoro-soro inosanganisira chiedza, makanika, magetsi, zvinhu, kuona, uye kutonga. Iyo yakakosha kutsigira tekinoroji yepamberi laser kugadzira tekinoroji uye inogona kugadzirisa matambudziko ayo echinyakare nzira dzekugadzira hazvigone kupedzisa. Iyo tekinoroji yepamusoro-soro inotsigirwa uye inosimudzirwa nenyika. Parizvino, laser cladding tekinoroji yave imwe yenzira dzakakosha dzekugadzirira kwezvinhu zvitsva, kukurumidza uye kwakananga kugadzirwa kwesimbi zvikamu, uye girinhi remanufacturing yeakakundikana simbi zvikamu. Yakave ichishandiswa zvakanyanya mundege, peturu, mota, kugadzira michina, kuvaka ngarava, uye kugadzira mold. nemamwe maindasitiri. Kuti vasimudzire indasitiri yelaser cladding tekinoroji, vaongorori vanobva kumativi ese enyika vakaita tsvakiridzo yakarongeka pamatekinoroji akakosha anosanganisirwa mulaser cladding uye vakafambira mberi zvakanyanya. Kune huwandu hukuru hwekutsvagisa, mapepa emusangano, uye patents kumba nekune dzimwe nyika kuunza laser cladding tekinoroji uye mashandisirwo ayo matsva: zvinosanganisira laser cladding midziyo, zvigadzirwa, maitiro, kutarisa uye kutonga, kuongorora kwemhando, maitiro simulation uye simulation, nezvimwe. kusvika ikozvino, laser cladding tekinoroji haigone kushandiswa mumaindasitiri pamwero mukuru. Tichiongorora zvikonzero, pane zvinhu zvakaita seyakatarisana nehurumende zvinhu, zvipimo pakukura kwelaser cladding tekinoroji pachayo, uye chiyero chekucherechedzwa kwelaser cladding tekinoroji nezvikamu zvese zvenzanga. Naizvozvo, kuti tiwane yakazara maindasitiri ekushandisa kwelaser cladding tekinoroji, isu tinofanirwa kuwedzera kushambadza, kutungamirwa nemusika kudiwa, kutarisa pakupaza zvinhu zvakakosha zvinotadzisa budiriro, uye kugadzirisa matekinoroji akakosha anosanganisirwa mukushandisa kweinjiniya. Ini ndinotenda kuti munguva pfupi iri kutevera, Iyo minda yekushandisa uye kusimba kweiyo laser cladding tekinoroji icharamba ichikura.

Heano mashoma ekushandisa mienzaniso yelaser cladding: iyo yakatarisana simba density yelaser beam inogona kusvika 1010 ~ 12W/cm2, uye mwero wekutonhora wezvinhu unogona kunge wakakwira se1012K/s. Hunhu hwakazara uhu hahungopi mikana yekukura kwezvidzidzo zvitsva mune zvesainzi. Inopa hwaro hwakasimba uye chimbo chisati chamboitika chekuzadzikiswa kwezvinhu zvitsva kana nzvimbo itsva dzinoshanda. Iyo yakanyunguduka yakagadzirwa nelaser cladding iri kure neiyo yakaenzana mamiriro ekukurumidza kutonhora mamiriro pasi pepamusoro-tembiricha gradients, zvichikonzera kuumbwa kwenhamba yakawanda ye supersaturated yakasimba mhinduro, metastable zvikamu, uye kunyange nhanho nyowani muchimiro chekusimba, icho chine. yakasimbiswa nenhamba huru yezvidzidzo. Inopa hutsva hwe thermodynamic uye kinetic mamiriro ekugadzira inoshanda graded in-situ autogenous particle-yakasimbiswa composite layers. Panguva imwecheteyo, kugadzirira kwezvinhu zvitsva nelaser cladding tekinoroji ndiyo hwaro hwakakosha hwekugadzirisa nekugadzirisazve zvikamu zvakakundikana pasi pemamiriro akanyanya uye kugadzirwa kwakananga kwesimbi. Yakagamuchira kutariswa kukuru uye kutsvagisa kwakasiyana-siyana kubva munharaunda yesainzi nemabhizinesi pasi rese. Parizvino, laser cladding tekinoroji inogona kushandiswa kugadzira iron-based, nickel-based, cobalt-based, aluminium-based, titanium-based, magnesium-based, uye zvimwe simbi matrix composite zvinhu. Inoshanda Classified: machira ane imwechete kana akawanda mabasa anogona kugadzirirwa, senge kupfeka kuramba, corrosion resistance, high-temperature resistance, etc., pamwe neakakosha machira ekushanda. Kubva pamaonero ehurongwa hwezvinhu zvinoumba kupfekedzwa, yakagadziridzwa kubva kune bhinary alloy system kusvika kune yakawanda-component system. Iyo alloy kuumbwa dhizaini uye kuwanda kwemaitiro e-multi-component masisitimu akakosha ekusimudzira mafambiro ekugadzirira kwezvinhu zvitsva nelaser cladding mune ramangwana. Tsvagiridzo nyowani inoratidza kuti simbi-yakavakirwa simbi zvinhu zvinotonga nyika yangu mainjiniya application. Panguva imwecheteyo, kukundikana kwezvinhu zvesimbi (zvakadai sekuora, kupera, kuneta, nezvimwewo) zvinowanzoitika panzvimbo yekushanda yezvikamu, uye nzvimbo inoda kusimbiswa. Kuti usangane nemamiriro ebasa reiyo workpiece, kushandisa zvidimbu zvakakura zve-situ-yakagadzirwa particle-yakasimbiswa simbi-based composite zvinhu kwete kungorasa zvinhu asiwo zvinodhura zvakanyanya. Kune rumwe rutivi, kana uchiongorora zvisikwa zvipenyu kubva pakuona kwebionics, kuumbwa kwavo kwakaoma kunze uye zvishoma mukati, uye maitiro avo akaoma kunze uye akaoma mukati. Uyezve, density-sparse, kuoma-kuoma kunoshanduka mune gradient kubva kunze kuenda mukati. Izvo zvinhu zvechisikigo biomaterials Chimiro chakakosha chinoita kuti ive nekuita kwakanakisa.

Zvinoenderana nemamiriro ebasa akakosha uye zvinodiwa zveinjiniya, pane kudikanwa kwekukurumidzira kugadzira simbi nyowani matrix inoumbwa zvinhu zvine yakasimba uye yakaoma musanganiswa uye gradient kuita. Naizvozvo, kushandisa laser cladding kugadzirira gradient inoshanda in-situ-yakagadzirwa chidimbu-yakasimbiswa simbi matrix macomposites ayo akasungirirwa nesimbi kune substrate hakusi iko kudiwa kwekukurumidzira kweinjiniya maitiro asiwo maitiro asingadzivisiki mukuvandudza tekinoroji yelaser surface modification. . Laser cladding tekinoroji yakanzi igadzirire in-situ autogenous particle-yakasimbiswa simbi matrix composites uye inoshanda giredhi zvinhu, asi mazhinji acho anoramba ari padanho rekuumbwa uye ongororo yekushanda, kutonga kwemaitiro paramita, saizi, nzvimbo, uye vhoriyamu reshiyo. chikamu chekusimbisa Iyo haisati yasvika padanho rinodzoreka. Iyo gradient basa inoumbwa kuburikidza neakawanda-layer coating, uye pane zvisingadzivisike dambudziko rekusasimba kwekubatana kwekubatanidza pakati pematanho. Pachine rwendo rurefu rwekufamba pamberi pekuita. Kushandisa laser cladding tekinoroji kugadzirira simbi-yakavakirwa pamusoro inoumbwa zvinhu zvine inodzoreka particle saizi, huwandu, uye kugovera, zvakakodzera kuenzana kusimba uye kuoma, uye kubatanidza gradient mabasa uye in-situ inozvigadzira pachayo kusimbaradza inzira yakakosha yekusimudzira mune ramangwana. Zvinyorwa zvekutsvaga zvinosanganisira:

1. Iyo tekinoroji, nzira uye misimboti yekuvharisa zvinhu kuumbwa, chimiro uye dhizaini dhizaini uye tekinoroji yekudzora yekuita maitiro.
2. Kugadzwa kweiyo thermodynamic uye kinetic modhi yekusimbisa chikamu chekunaya, kukura uye kusimbiswa kweanoshanda giredhi autogenous particle-yakasimbiswa simbi matrix composite yakagadzirwa nelaser cladding.
3. .Particle-reinforced phase morphology, chimiro, basa uye composite bionic dhizaini uye kutonga tekinoroji yehukuru, huwandu uye kugovera.
4. Tsvagiridzo pamisimboti, akakosha zvinhu uye nzira dzekugadzirisa kurongedza kuumbwa, chimiro uye kuita gradient kutonga.
5. Kutarisa, kuongorora kutonga, uye hunhu hwemacro uye micro interfaces; kuongororwa uye kuongororwa kwezvakajairwa zvimiro zveanoshanda graded in-situ particle-reinforced metal matrix composites, pamwe nekupfeka maitiro uye maitiro ekukundikana pasi pemamiriro akasiyana ekushanda. Kubudirira mune izvi zviri mukati mekutsvagisa kunogona kugadzirisa dambudziko rekusawirirana mukuenderana pakati pekupotera uye substrate uye inokurumidza kutsemuka, uye kukurudzira kuwedzera kwenzvimbo yekushandisa yelaser cladding tekinoroji.
