Lub pob zeb diamond pom hniav ntu yog cov hmoov hlau tshwj xeeb cov khoom lag luam ua tiav los ntawm cov pob zeb diamond thiab hlau hmoov, thiab nws tau qiv qee txoj hauv kev thiab cov txheej txheem los ntawm cov pa hmoov metallurgy hauv kev tsim khoom. Txawm li cas los xij, vim qhov tshwj xeeb ntawm pob zeb diamond thiab qhov nyuaj thiab qhov sib txawv ntawm kev ua cov khoom, nws yog qhov nyuaj rau kev ntsuas los ntawm cov qauv kev ua haujlwm zoo tshaj li cov khoom siv hmoov metallurgy. Qhov tseem ceeb uas muaj kev cuam tshuam ntau dua rau kev ua haujlwm ntawm ntu yog lub binder. Cov hauv qab no yuav tsum tau txiav txim siab nyob rau hauv kev xaiv ntawm ntu binder hauv kev tshawb fawb ntau lawm: 1. Muaj peev xwm tuav pob zeb diamond; 2. Rau cov khoom sib txawv, kev sib koom tes thiab kev sib koom ua ke ntawm pob zeb diamond thiab daim ntawv cog lus hnav tsis kam; 3. Tsim nyog txheej txheem txheej txheem; 4. Tus nqi tsim nyog. Lub zog tuav ntawm daim ntawv cog lus rau lub pob zeb diamond muaj lub zog tuav lub zog thiab tshuaj muaj zog tuav. Tus neeg kho tshuab tuav quab yuam yog tsuas yog txiav txim siab los ntawm elastic modulus ntawm lub binder. Cov ntsiab lus uas ua rau kom cov elastic modulus ntawm cov ntaub ntawv xws li Cr, Mn, W los yog WC nyuaj theem tuaj yeem ua rau muaj zog tuav thiab ua rau kom hnav tsis kam rau tib lub sijhawm. Ntawm chav kawm, siab abrasion tsis kam yog tsis haum rau lub pob zeb diamond ntug. Tshuaj tuav quab yuam yog tsim los ntawm vuam los yog chemical bond ntawm pob zeb diamond thiab daim ntawv cog lus. Nws tuaj yeem tsis tsuas yog nce lub neej ntawm lub taub hau cutter, tab sis kuj nce qhov siab ntawm lub pob zeb diamond rau ntawm lub taub hau cutter, tsim qhov chaw loj dua rau kev txiav, thiab txhim kho kev txiav. Txhawm rau txhim kho cov tshuaj tuav lub zog yog txhawm rau ua kom cov dej noo thiab kev sib txuas ntawm daim ntawv cog lus rau pob zeb diamond. Lub zog carbide tsim cov ntsiab lus Ti, Cr, thiab lwm yam tuaj yeem ua rau tus neeg sawv cev sib txuas kom ntub cov pob zeb diamond thiab daim ntawv cog lus nrog cov pob zeb diamond los tsim cov carbides kom muaj zog sib txuas. Tau kawg, cov xim tseem ceeb no kuj corrode pob zeb diamond, yooj yim coarsening carbides, ua cov kab nrib pleb los yog pores, thiab deteriorating txiav kev ua tau zoo.
