Yakanyanya Tembiricha Kudzora kweLaser Systems uye Maindasitiri Zvishandiso Kubva 2002
Mutauro
Kutsemuka mulaser cladding kunonyanya kukonzerwa nekupisa kwekushushikana, kukurumidza kutonhora, uye zvisingaenderane zvinhu zvinhu. Matanho ekudzivirira anosanganisira optimizing process parameters, preheating, uye kusarudza akakodzera hupfu. Kutadza kutonhora kwemvura kunogona kutungamira mukupisa uye kuwedzera kwakasara kushushikana, zvichiita kuti kutonhora kwakavimbika kuve kwakakosha pakudzivirira kutsemuka.
Kugadzira mutswe idambudziko rakajairika mumalaser cladding maitiro, anowanzo kukanganisa kunaka uye kusimba kweiyo clad layer. Kunzwisisa zvinokonzeresa uye kuita matanho ekudzivirira anoshanda kwakakosha kuti uwane mhedzisiro yakanaka. Uyezve, kuchengetedza basa rakakodzera remvura inotonhorera kwakakosha, sezvo kutonhora kukundikana kunogona kuwedzera zvakanyanya njodzi yekutsemuka.
Zvakajairwa Zvinokonzera Kutsemuka muLaser Cladding
1. Thermal Stress: Chimwe chezvikonzero zvinonyanya kukonzera kuputika ndiko kushushikana kwekushisa kunokonzerwa nekusawirirana mu coefficient of thermal expansion (CTE) pakati pezvinhu zvepasi uye cladding layer. Munguva yekutonhora, kushushikana kwekushushikana kunokura pane interface, kuwedzera mukana wekutsemuka.
2. Kukurumidza Kutonhodza: Kana chiyero chekutonhora chiri kukurumidza, kusara kunetseka mukati mezvinyorwa hakugoni kusunungurwa zvinobudirira, zvichiita kuti pave nekugadzirwa kwekuputika, kunyanya mukuoma kwepamusoro kana brittle zvinhu.
3. Material Property: Ngozi yekutsemuka inowedzera kana uchishandisa substrates ine kuoma kwakanyanya (semuenzaniso, kudzima kana carburized/nitrided materials) kana poda dzine kuomarara zvakanyanya kana kusaenderana. Masubstrates ane matinji ekuneta kana kusaenderana kwemhando yepamusoro anogonawo kubatsira mukutsemuka.
Kudzivirira Matanho
1. Kugadzirisa Maitiro Parameters: Kunyatsogadzirisa laser simba, scanning speed, uye powder feed rate inobatsira kugadzirisa kunyunguduka kwekushisa kwedziva uye kutonhora kwemhepo, kuderedza kupisa kwemagetsi uye njodzi yekutsemuka.
2. Preheating and Controlled Cooling: Preheating the base material and applying slow, controlled cooling post-cladding inogona kubatsira kubvisa kushushikana kwakasara, kuderedza mikana yekukura kwekuputika.
3. Kusarudza Right Powder Material: Kusarudza poda inoenderana nehwaro zvinhu mumafuta ekuwedzera zvinhu uye kuoma kwakakosha. Kudzivisa kuoma kwakanyanya kana kusawirirana kwemafuta kunoderedza kushushikana kwemukati uye kuumbwa kwekuputika.
Mhedzisiro yeChiller Kutadza paCrack Formation
Chiller yemvura inoita basa rakakosha mukutonga kwekupisa kwemidziyo yelaser cladding. Kana iyo chiller yemvura ikatadza , inogona kutungamira mukupisa kweiyo laser sosi kana zvakakosha zvinhu, kukanganisa kugadzikana kwemaitiro. Kuwedzeredza kunogona kushandura kunyunguduka kwemadziva uye kuwedzera zvakanyanya kusara kushushikana mune izvo zvinhu, zvichibatsira zvakananga mukupwanya kuumbwa. Kuve nechokwadi chekuvimbika chiller kuita kwakakosha pakuchengetedza kunaka kwekupfeka uye kudzivirira kukanganisa kwechimiro.
Mhedziso
Kutsemuka muLaser cladding kunogona kudzikiswa zvinobudirira nekugadzirisa kushushikana kwekupisa, kusarudza zvinhu zvakakodzera, uye kuchengetedza yakagadzikana kutonhora mamiriro. Iyo yakavimbika mvura chiller chikamu chakakosha cheiyo system, inobatsira kuve nechokwadi chekudzora tembiricha uye kuvimbika kwemidziyo yenguva refu.
Tiripo nokuda kwenyu kana muchitida.
Ndapota zadza fomu kuti ubate nesu, uye isu tichafara kukubatsira.

TEYU S&A Chiller yakavambwa muna 2002 iine makore makumi maviri nematatu echiller yekugadzira ruzivo, uye ikozvino inozivikanwa seyekutonhora tekinoroji piyona uye akavimbika shamwari muindasitiri yelaser.
