Uburyo bwo gucumura muri Powder Metallurgie

1. Icyaha ni iki?

Gucumura ni uburyo bukomeye bwo kuvura ubushyuhe bukoreshwa mubikoresho byifu. Mu gushyushya ibikoresho munsi yikibanza cyacyo cyo gushonga, gucumura bitera inzira yo gukwirakwiza ikora amajosi nubusabane hagati yuturere duturanye, bityo bigatanga imbaraga nubusugire bwimiterere kubintu. Iyi nzira ningirakamaro muguhindura ifu irekuye igahinduka ikintu cyinshi, gikomeye kandi gifite imiterere yihariye.

2. Inzira yo gucumura

Igikorwa cyo gucumura gitangirana no gushyushya ifu yuzuye. Ubu buryo bwo kuvura butera uburyo bwo gukwirakwiza byoroha gukora amajosi n'imigozi hagati y'ibice. Mbere yo gucumura, compact ikora intambwe zingenzi zo kwitegura, harimo kuvanaho amavuta no kugabanya okiside yo hejuru. Izi ntambwe zemeza ko compact yagenewe gucumura neza.

3. Ibyiciro byo gucumura

Inzira yo gucumura irashobora gucikamo ibice byinshi byingenzi:

1. Gukuraho Kanda Amavuta na Evaporation: Kureba ko amavuta yose yakoreshejwe mugihe cyo gukanda avaho.
2. Kugabanya Oxide yo hejuru: Iyi ntambwe yoza ifu yifu, bigatuma irushaho gukora mugihe cyo gucumura.
3. Icyaha gikomeye: Ijosi rirakura kandi rigakura kumurongo uhuza, biganisha kumiterere ikomeye kandi ifatanye.

4. Ubwoko bwo gucumura

Hariho uburyo butandukanye bwo gucumura, buri kimwe gikwiranye nuburyo butandukanye:

• Icyaha gikomeye: Harimo guhuza ibice bitagira icyiciro cyamazi. Ubu buryo bukoreshwa mubikoresho aho icyiciro cyamazi cyaba kitifuzwa.
• Icyiciro Cyamazi: Inyongeramusaruro ishonga mugihe cyibikorwa, ifasha uduce duto duto kandi densification. Ubu buryo ni ingirakamaro mu kugera ku bucucike buri hejuru no kuzamura imashini.
• Ultra-Hejuru-Ubushyuhe bwo gucumura (UHTS): Bikorewe ku bushyuhe bugera kuri 2500 ° F, UHTS ikoreshwa kugirango igere ku bintu byiza nko kwinjiza cyane no gukomera.

5. Ibikoresho bikwiranye no gucumura

Ubwoko butandukanye bwibikoresho birashobora gukorerwa icyaha, buri kimwe gitanga inyungu zidasanzwe bitewe nibisabwa:

• Ibyuma: Ibyuma bisanzwe bikoreshwa mugucumura harimo ibyuma, umuringa, aluminium, na titanium. Ibyo byuma bikunze gukoreshwa mumodoka, mu kirere, no mubikorwa byinganda.
• Amavuta: Amavuta avanze nk'ibyuma, umuringa, n'umuringa byiganje mu kurema ibice bisaba imiterere yihariye.
• Ceramics.
• Ibigize.

Buri kintu cyo gucumura ibintu cyateganijwe kugirango hongerwe ibintu nkubucucike, imbaraga, hamwe nubushyuhe bwumuriro, bigatuma gucumura inzira zitandukanye mubikorwa.

6. Inyungu zo gucumura

Gucumura bitanga ibyiza byinshi, harimo:

• Kongera imbaraga n'ubunyangamugayo: Inzira ishimangira cyane ifu yuzuye.
• Gutezimbere Umutungo: Emerera ikwirakwizwa ryinyongera, kongerera imbaraga nibindi bintu.
• Kugenzura ubukana n'ubucucike: Gushoboza kugenzura neza ibintu byuzuye kandi byuzuye.
• Imikorere ya rukuruzi na mashini: Kunoza imikorere.
• Gukora Net-Shusho: Korohereza umusaruro wuburyo bugoye hamwe n imyanda mike.

7. Porogaramu ifatika yo gucumura

Icyaha gisanga porogaramu mu nganda zitandukanye:

• Imodoka: Ikoreshwa mugukora ibikoresho, ibyuma, nibindi bikoresho bikomeye.
• Ikirere: Ibyingenzi kubyara ingufu-nyinshi, ibice byoroheje.
• Ubuvuzi: Byakoreshejwe mukurema ibintu biramba, biocompatible yatewe nibikoresho byo kubaga.

8. Udushya hamwe nigihe kizaza mugucumura

Iterambere rya vuba mu buhanga bwo gucumura harimo:

• Gukora inyongera no gucapa 3D: Guhindura uburyo ibice byacuzwe byakozwe, bituma habaho igishushanyo mbonera cyiza kandi gikora neza.
• Ibikoresho byiza byo gucumura: Gutezimbere mu itanura nubuhanga byongera imikorere no kugabanya ibiciro.

9. Umwanzuro

Inzira yo gucumura ni ntangarugero mu ifu ya metallurgie, ihindura ifu irekuye ibice byuzuye, imbaraga-nyinshi zifite ibintu byabigenewe. Nka tekinoroji igenda itera imbere, ikoreshwa ninyungu zo gucumura bikomeje kwaguka, bishimangira uruhare rwayo mubikorwa bitandukanye.

10. Ibibazo

Ikibazo: Ni ibihe bikoresho bishobora gucumurwa?Igisubizo: Ubwoko butandukanye bwibyuma nibisigazwa, harimo ibyuma, umuringa, aluminium, titanium, ububumbyi nka alumina na zirconi, hamwe nibintu nka matrike ya matrix, birashobora gucumurwa.

Ikibazo: Nigute gucumura bigira ingaruka kumiterere yanyuma?Igisubizo: Gucumura byongera imbaraga, ubucucike, hamwe nuburinganire bwimiterere yibicuruzwa byanyuma.

Ikibazo: Icyaha gishobora gukoreshwa muburyo bwose bw'ibyuma?Igisubizo: Mugihe ibyuma byinshi bishobora gucumurwa, bimwe birashobora gusaba ibintu byihariye cyangwa inyongeramusaruro kugirango ugere kubisubizo byiza.
