Cov hmoov hlau feem ntau siv hauv cov cuab yeej pob zeb diamond thiab nws cov yam ntxwv

Raws li kev siv sib txawv, ntau yam thiab cov txheej txheem ntau lawm ntawm cov cuab yeej pob zeb diamond, cov hmoov sib txawv yog xav tau, xws li hlau, tsis yog hlau, alloy, compound, thiab lwm yam. Cia peb qhia cov hmoov hlau uas feem ntau siv hauv cov cuab yeej pob zeb diamond thiab lawv cov yam ntxwv kom ntxaws.
1. Copper hmoov: electrolytic tooj liab hmoov muaj formability zoo thiab yog dav siv rau sintering tom qab txias nias txoj kev.
2. Hlau hmoov: Muaj cov hmoov hlau txo, electrolytic hlau hmoov thiab carbonyl hlau hmoov. Raws li cov ntaub ntawv binder, hlau hmoov muaj qhov zoo: tus nqi qis thiab zoo wettability nrog pob zeb diamond; Kev sib raug zoo nrog cov khoom siv pob txha.
3, cobalt hmoov: irregular spongy, binder khoom, zoo: formability thiab zoo sinter; Ua kom lub zog khoov ntawm lub log tsheb; Thiab pob zeb diamond adhesion, zoo wettability.
4, tin hmoov: particles yog tee, greyish dawb hmoov, yooj yim oxidation, daj tom qab oxidation, atomization txoj kev. Kev ua haujlwm yog: txhim kho lub peev xwm sinter ntawm lub cev (txo cov ntsiab lus melting); Nws yog ib qho yooj yim los tsim cov tshuaj sib xyaw intermetallic, uas tuaj yeem txhim kho qhov hnav thiab deformation zog.
5, tungsten carbide: dub, tsis muaj txhua yam suav nrog, sponge ntxeem tau, txo txoj kev. tungsten thiab tungsten carbide feem ntau yog ntxiv rau hauv matrix li cov ntaub ntawv pob txha los txhim kho qhov hnav tsis kam ntawm matrix. Cov ntsiab lus siab dhau lawm yog ib qho yooj yim los ua kom lub brittleness ntawm lub matrix.
