Setšoantšo sa ho utloisisa sebōpi sa "vacuum diffusion welding".

1. Vacuum Diffusion Welding: Vacuum Diffusion Welding e bolela mokhoa oa ho tjheseletsa oo likarolo tse haufi-ufi li bolokoang mochesong o itseng le khatello ka nako e itseng sebakeng sa vacuum, e le hore liathomo tse pakeng tsa libaka tse amanang le tsona li arolelane. theha khokahano. E ke ke ea hlokomela feela kamano pakeng tsa mofuta o tšoanang oa lisebelisoa tsa tšepe tse sa tšoaneng, empa hape e hlokomela kamano pakeng tsa lisebelisoa tsa tšepe le tsa ceramic, lisebelisoa tse kopantsoeng joalo-joalo.

2. Melemo ea ho tjheseletsa vacuum diffusion:

• Mocheso o tlase oa welding le mefuta e mengata e fapaneng ea lisebelisoa tse sebetsang. Nakong ea li-welding tsa diffusion, matrix ha e qhibilihe kapa e chesa ho feta tekano, e ka lemohang ho hokahanya ha thepa eo ho leng thata ho e finyella ka mekhoa e meng.

• Matla a holimo a tjheseletsa le boleng bo botle ba manonyeletso. Sebopeho le ts'ebetso ea motsoako oa welded li haufi le lisebelisoa tsa motheo, 'me boleng ba motsoako bo tsitsitse.

• Ts'ebetso ea welding ha e nkeloe sebaka. Likarolo tse nang le meaho e rarahaneng le liphapang tse kholo tsa botenya li ka chesoa, 'me li-welds tse ngata li ka chesoa ka nako e le ngoe.

• Nyenyane tjheseletsa deformation, a loketse bakeng sa ho etsoa ha sebopeho-mosebetsi o kopantsweng ho nepahala dihlahiswa.

3.Ts'ebetso ea ho theha motsoako oa tjheseletsa ea vacuum diffusion:

Kopano ka mocheso oa kamore

Mothati oa 1: Deformation Deformation

Deformation e sa reroang ea likaroloana tse ka holim'a metsi (microscopic roughness) le lifilimi ho theha tekanyo ea pele ea ho kopana le mochine.

Mothati oa 2: Phetoho ea Sehokelo sa Phatlalatso

Khokahano e holofala ha nako e ntse e ea, 'me e tsoela pele ho theha sebopeho se thata ho sehokelo.

Mothati oa 3: Ho nyamela ha li-interfaces le masoba

Ka ho tsoela pele ho hasana, khokahanyo e entsoeng e matlafatsoa ka ho eketsehileng, sebaka sa khokahanyo se tiileng se atolosoa, lesoba la li-interface le tlosoa, 'me mokhatlo o kopanetsoeng le ho hlophisoa ho etsoa homogenized.

4.The lintlha tse ka sehloohong tshebetso amang vacuum diffusion tjheseletsa

• Mocheso: o ama sekhahla sa phallo ea athomo, e amang matla a lenonyeletso la weld, ka kakaretso makhetlo a 0.5 ho isa ho 0.8 ho feta ntlha ea ho qhibiliha ha thepa.

• Khatello: Eketsa sebaka se sebetsang sa ho ikopanya le substrate mme u khothaletse deformation ea polasetiki ea bokaholimo bo kopaneng.

• Vacuum degree: degassing, anti-oxidation, le ho ntlafatsa ts'ebetso ea weldment.

• Nako ea ho arola: Nako e nepahetseng ea ho hasana e thusa ho ntlafatsa ho tšoana ha lisele tse kopanetsoeng.

5. Litlhoko tse tiileng tsa lisebelisoa tsa tjheseletsa tsa vacuum diffusion:

• Nako e lekaneng ea ho futhumatsa e sebetsang hantle

• Tekanyo e phahameng ea vacuum

• Ho nepahala ho laola mocheso o phahameng

• Ho tšoana hantle ha mocheso oa sebōpi

• Ho nepahala ho laola khatello e phahameng

• Thepa e bolokehile ebile e ka tšeptjoa

Vacuum diffusion welding sebōpi ke sesebelisoa sa bohlokoa se nepahetseng.

Tšebeliso e nepahetseng ea sebōpi sa "vacuum diffusion welding" e phetha karolo ea bohlokoa ho netefatsa boleng ba ho tjheseletsa ha thepa, ho lelefatsa bophelo ba lisebelisoa le ho fokotsa litšenyehelo tsa tlhahiso.

Taolo ea mekhahlelo e mengata ea ho nepahala ha khatello, ho ikamahanya le maemo a hlooho ea khatello le ts'ebetso ea tšimo ke tataiso ea nts'etsopele ea sebopi sa vacuum diffusion welding nakong e tlang.

6. Kopo ea sebōpi sa vacuum diffusion welding

6.1 Lisebelisoa tsa tšepe

Thepa e tšoanang: vacuum diffusion welded titanium alloy hollow rectifier blades le aluminium alloy e pholileng ka metsi lipoleiti li sebelisoa bakeng sa lisebelisoa tsa aero-engine le mekhoa ea ho futhumatsa moea ka ho latellana.

Lisebelisoa tse fapaneng: likaroloana tsa bimetallic tse entsoeng ka vacuum diffusion welding ea koporo le tšepe li sebelisoa haholo joalo ka li-cylinders tsa pompo ea hydraulic, lipane tsa kabo ea oli, lijakete tsa oli tsa mashala, li-rotor tsa bimetallic, jj.

6.2 Lisebelisoa tse se nang tšepe

lintho tse bonahalang:

• α-Al2O3 ceramics le metallic nickel; 

• high-entropy alloy CoCrFeMnNi le tšepe e sa hloekang;

• WC-Co e entsoeng ka samente carbide le aluminium, joalo-joalo; 

• Motsoako oa Ni3Al intermetallic, motsoako o le mong oa kristale, joalo-joalo.

kopo: Pakete ea elektronike; likarolo tsa sebopeho sa mocheso o phahameng, joalo-joalo.

Likarolo: Hlōla liphapang lipakeng tsa thepa le ho kopanya thepa ea tsona e ntle ho holisa mefuta e mengata ea lisebelisoa.

7. Thepa ea Vacuum Diffusion Welding

7.1 Sets'oants'o sa sebopeho sa sebōpi sa tjheseletsa sa vacuum diffusion

7.2 Melemo ea ACME Vacuum Diffusion Welding Furnace

• Mochine oa khatiso o kopantsoe le kamore ea ho futhumatsa.

• Ho nepahala ho phahameng ha taolo ea khatello le taolo ea phalliso, le ts'epahalo e ntle ea lisebelisoa.

• Ho ts'oana hantle ha mocheso oa sebōpi le boleng bo phahameng ba lihlahisoa tsa li-welding tsa diffusion.

• The indenter is easy to install and disassemble, and it can also be used as an independent brazing furnace without pressurization, and the equipment has strong versatility.

7.3 Likarolo tsa Tekniki tsa ACME Vacuum Diffusion Welding Furnace

• Ntho ea ho futhumatsa e entsoe ka modularized, e laoloa ke lenaneo la mekhahlelo e mengata ea PID, 'me ho tšoana ha mocheso ho lokile.

• E na le sensor ea khatello e tsoang linaheng tse ling ea Jeremane ea 0.001, ho nepahala ho laola khatello e phahameng; e nang le sensor ea 10um e phahameng e nepahetseng, taolo e nepahetseng ea phallo;

• Sistimi e ikemetseng ea taolo ea khatello ea tlatsetso ho netefatsa khatello e nepahetseng ea kamehla ea pompo ea phallo.

• Sebopeho sa tiiso se matla sa setsebi se tiisa ts'ebetso e tsitsitseng tlas'a vacuum le khatello e phahameng ntle le ho lutla.

• Sebaka sa khatello se netefatsoa ke ketsiso ea likarolo tse fokolang, indenter e kaholimo / e tlase e na le moeli o lekaneng oa polokeho, ha ho na deformation e nyane tlasa mocheso o phahameng, 'me bokaholimo ba mochini o hatelitsoeng o bataletse.
