Kev soj ntsuam ntawm Kev Tsim Cov Txheej Txheem rau Hard Alloy Sawb

Peb txhua tus paub tias cov khoom tseem ceeb ntawm cov khoom siv tawv tawv yog micro loj carbide hmoov ntawm siab hardness thiab refractory hlau. Yog li ntawd, nws yog ib qho nyuaj heev, thiab muaj coob tus neeg nug yog hais tias lub hard alloy siv rau lub hard alloy pob hniav yog hlau? Yuav ua li cas nyuaj alloy tuaj txog? Hauv qab no, cov chaw tsim khoom nyuaj alloy sawb yuav piav qhia rau koj txog kev tsim cov txheej txheem nyuaj alloy pob hniav nyuaj alloy.

1. Txoj kev tsim khoom ntawm txoj hlua ntev tawv tawv yog raws li hauv qab no: ua ntej, kev sib tsoo alloy yog tsim los ntawm high-zog pob sib tsoo; Tom qab ntawd, raws li qhov ntsuas qhov hnyav ntawm cov khoom siv tawv alloy, qhov sib xyaw yog ntxiv thiab raug rau kev txhawb nqa pob milling. Lub zog alloy sib tov ua los ntawm pob milling yog ces nqus sintered rau hauv cov duab.

2. Cov khoom siv tawv tawv siv rau qhov ntev sawb nyuaj alloy pob hniav feem ntau suav nrog tungsten carbide (WC) thiab titanium carbide (TC). Hard alloys feem ntau suav nrog tungsten cobalt raws (WC + Co) nyuaj alloys (YG), tungsten titanium cobalt raws (WC + TiC + Co) nyuaj alloys (YT), tungsten tantalum cobalt raws li (WC + TaC + Co) nyuaj alloys (YA), tungsten cobalt (WC + TA + C) raws li hard alloys (YW).

3. Ib hom ultra-nplua nyuaj alloy pob hniav nyuaj alloy thiab nws txoj kev tsim khoom. Cov hlau yog cov khoom sib xyaw ua ke uas muaj peb lub ntsiab lus: WC nyuaj theem, Co Al raws li kev sib txuas hlau theem, thiab lub ntiaj teb tsis tshua muaj hlau hlau theem; Cov muaj pes tsawg leeg thiab hnyav cov ntsiab lus ntawm alloy yog raws li nram no: Co Al bonding hlau theem: Al13-20%, Co80-87%; Composite alloy: Co-AL 10-15%, Re1 ~ 3%, WC82 ~ 89%. Tom qab ntawd, raws li qhov ntsuas qhov hnyav ntawm cov khoom siv tawv alloy, cov khoom sib xyaw yog sib xyaw thiab ua rau muaj zog pob milling. Lub zog alloy sib tov ua los ntawm pob milling yog ces nqus sintered ntawm sintering kub ntawm 1360 ℃ thiab tuav lub sij hawm ntawm 20 feeb. Qhov zoo tshaj plaws hard alloy yog tsim.
