Hmoov metallurgy sintering hardening yog txheej txheem uas sib xyaw ua ke sintering thiab kev kho cua sov, uas yog, tom qab qee yam khoom siv tau sintered thiab txias sai, martensite (feem ntau> 50%) yog tsim nyob rau hauv cov qauv metallographic, kom cov khoom siv hauv kev tsim khoom. lub luag haujlwm zoo dua thiab txhim kho kev lag luam.

Qhov zoo ntawm sintering hardening:

1. Cov txheej txheem kho cua sov tuaj yeem raug tshem tawm

2. Tsis txhob muaj kuab paug ntawm cov roj quenching

3. Yooj yim rau npau taws hauv huab cua

4. Txo cov khoom deformation

5. Txhim kho kev tswj qhov loj

6. Txhim kho kev lag luam

7. Daim ntawv thov ntawm sinter hardening

Hmoov metallurgy sintered hardening cov ntaub ntawv feem ntau yog siv los tsim cov khoom nruab nrab thiab siab ceev.Tam sim no, cov txheej txheem sinter hardening feem ntau yog siv rau cov khoom uas nyuaj rau quench vim qhov loj thiab cov duab.Xws li iav qhov chaw, synchronizer hubs, tshwj xeeb-zoo li tus los yog nyias-walled knots thiab lwm yam structural qhov chaw.Hauv cov ntsiab lus, hlau-raws li hmoov metallurgy sinter hardening yog ib qho txiaj ntsig zoo tshaj plaws los hloov cov hmoov metallurgy cov txheej txheem cua sov, thiab nws qhov zoo dua nws qhov tsis zoo.Kev xaiv cov ntaub ntawv tsim nyog rau sintering thiab hardening tsis tuaj yeem tsuas yog zam qhov tsis zoo ntawm kev kho cua sov thiab txo cov nqi, tab sis nco ntsoov tias cov khoom tom qab sintering thiab hardening yuav tsum tau tempered nyob rau hauv lub sij hawm, feem ntau ntawm tempering kub txog 180 ° C.
