Infiltration txheej txheem ntawm hmoov metallurgy

Cov hmoov compact yog hu rau cov kua hlau los yog raus rau hauv cov kua hlau, cov pores nyob rau hauv lub compact yog ntim nrog kua hlau, thiab cov khoom compact los yog qhov chaw yog tau los ntawm txias.Cov txheej txheem no hu ua immersion.Cov txheej txheem immersion cia siab rau sab nraud molten hlau kom ntub cov hmoov ntxeem tau lub cev.Nyob rau hauv qhov kev txiav txim ntawm capillary quab yuam, cov kua hlau ntws raws lub qhov hws ntawm cov lus hais los yog cov pores nyob rau hauv cov khoom kom txog thaum lub pores puv tag.

Qhov zoo ntawm tooj liab infiltration ntawm hmoov metallurgy hlau-raws li cov ntaub ntawv:
1. Txhim kho cov khoom siv kho tshuab;

2. Txhim kho kev ua haujlwm ntawm electroplating;

3. Txhim kho brazing kev ua tau zoo;

4. Txhim kho machining kev ua tau zoo;

5. Txhim kho hluav taws xob thiab thermal conductivity;

6. Yooj yim los tswj qhov loj ntawm qhov chaw;

7. Muaj kev sib khi zoo;

8. Ntau yam khoom tuaj yeem ua ke;

9. Txhim kho quenching zoo;

10. Hauv zos infiltration ntawm cov khoom tshwj xeeb yuav tsum tau ntxiv dag zog thiab hardening zog.

Cov yam ntxwv cuam tshuam:

1. Skeleton ceev
Raws li lub cev pob txha ceev nce, lub zog ntawm cov tooj liab-infiltrated steel nce ntau tshaj, thiab lub hardness kuj nce.Qhov no yog vim qhov nce ntawm cov pob txha pob txha, qhov nce ntawm pearlite, thiab cov ntsiab lus tooj liab tsawg.Nyob rau hauv cov nqe lus ntawm tus nqi, xaiv ib tug ntau dua skeleton density yuav txo tau cov ntsiab lus tooj liab, yog li kev txhim kho kev lag luam.

2. Ntxiv cov khoom Sn
Qhov sib ntxiv ntawm cov ntsiab lus qis melting Sn yog qhov zoo los ua kom qhov ceev thiab lub zog ntawm tooj liab-infiltrated sintered steel.Los ntawm daim duab kos duab Cu-Sn alloy, nws tuaj yeem pom tias cov tooj liab alloys uas muaj Sn muaj cov kua theem qis qis, uas tuaj yeem txhawb qhov kev nkag mus ntawm cov tooj liab.

3. Kub
Raws li qhov kub thiab txias nce, tus nqi ntawm cov nplej nthuav dav kuj nce, uas yog kev puas tsuaj rau kev txhim kho lub zog.Yog li ntawd, kom raug sintering-infiltration thiab tuav lub sij hawm yuav tsum tau xaiv nyob rau hauv lub premise ntawm kom ntseeg tau tias tag nrho cov alloying thiab homogenization ntawm Fe-C, tag nrho infiltration ntawm Cu, thiab tag nrho cov khoom ntxiv dag zog ntawm Fe-Cu.
