Cov ntsiab lus impurity yuav muaj nyob rau hauv tungsten raw cov ntaub ntawv nyob rau hauv daim ntawv ntawm cov tebchaw los yog cov kev daws teeb meem, thiab cuam tshuam nrog tungsten carbide thiab cobalt, ho cuam tshuam cov qauv thiab cov khoom ntawm cemented carbide. Nws tsuas yog muaj cov khoom tsis huv xws li sulfur, calcium, txhuas, molybdenum, manganese, tooj liab thiab hlau.
1. Qhov zoo thiab qhov tsis zoo
Thaum lub sij hawm sintering txheej txheem, cobalt tuaj yeem txhim kho cov wettability ntawm cov hlau, txhim kho qhov sib txuas sib txuas ntawm tungsten thiab matrix theem, thiab ua lub luag haujlwm hauv kev sib koom ua ke kom muaj zog sintering. Nyob rau tib lub sijhawm, nws tuaj yeem ua tiav lub hom phiaj ntawm kev txo cov sintering kub thiab txhim kho lub zog thiab toughness ntawm alloy. Cov kab ntau ntawm manganese yuav tsim kom muaj theem nruab nrab ruaj khov nyob rau theem ntawm cov ciaj ciam, ua kom huv ntawm cov ciam teb, txhim kho lub zog sib cuam tshuam ntawm matrix thiab qib kev sib txuas, thiab plasticity thiab toughness ntawm cov hlau.
Qee cov ntsiab lus impurity (xws li calcium thiab tooj liab) yuav ua rau muaj qhov tsis xws li qhov hauv cov hlau. Ib qho me me ntawm cov hlau tsis huv yuav ua rau cov qoob loo nthuav dav ntawm tungsten carbide, uas tsis tsim nyog rau kev ua kom zoo dua ntxiv thiab tsim cov qauv kev cog lus. Cov kab keeb phosphorus hauv cov hlau tsis zoo rau lub sijhawm sib txuas lossis cov khoom tawg hauv cov tungsten hais, uas yuav cuam tshuam kev sib cuag ntawm lub tsev cog khoom thiab theem nyuaj, thiab tib lub sijhawm txo qhov melting point ntawm cov hlau, uas ua rau muaj kev cuam tshuam ntawm kev sib txuas ntawm cov khoom sib txuas ntawm cov khoom sib txuas ntawm cov khoom sib txuas thiab cov txheej txheem nyuaj. Kev loj hlob ntawm tus kheej ntawm tungsten carbide nplej. cuam tshuam cov khoom ntawm cov alloy.
2. Cov kev daws teeb meem ib nrab
(1) Nyob rau hauv cov txheej txheem ntawm kev npaj cemented carbide, lub tshuab nqus tsev sintering tuaj yeem siv tau, uas tuaj yeem tshem tawm cov kab oxide impurities xws li silicon, magnesium thiab calcium, thiab roj impurities xws li oxygen hauv lub cev sintered, kom cov cemented carbide thiab nyuaj alloy tuaj yeem ua ke ua ke. Tus nqi ntawm cov ntawv xov xwm kev sib cais ntawm cov khoom theem sib cuam tshuam yog txo, thiab cov purity ntawm cemented carbide tau txhim kho.
(2) Ib qho tsim nyog ntawm cov ntsiab lus tsis tshua muaj hauv ntiaj teb tuaj yeem ntxiv los tswj cov ntsiab lus ntawm impurity ntsiab, uas tuaj yeem hloov pauv kev faib tawm ntawm impurities ntawm qhov sib cuam tshuam, txo cov nag lossis daus ntawm cov pa roj thiab tiam ntawm cov pores, thiab ua rau cobalt deposit ntawm lub tungsten carbide grain ciam teb los tsim cov khoom tawg, yog li ua lub luag haujlwm Nws tuaj yeem kho cov nplej thiab txhim kho lub zog thiab hardness ntawm cemented carbide.
