Lub luag haujlwm ntawm Cobalt Powder hauv Pob Zeb Diamond Cov Cuab Yeej

Cobalt hmoovyog ib qho tseem ceeb alloying tivthaiv rau siab -kev ua tau zoo pob zeb diamond cuab tam matrices. Feem ntau ua ke nrog hlau, tooj liab, npib tsib xee, thiab tin, nws yog dav siv nyob rau hauv kev thov daim ntawv thov -xws li siab -kawg granite sib tsoo blocks, PDC substrates, reinforced qhob core drilling me ntsis, thiab nyuaj- pob zeb pom ntu - ua cov hmoov tseem ceeb rau kev sib npaug hnav tsis kam thiab pob zeb diamond, toughness.

 

 

1. Superior pob zeb diamond wetting muaj peev xwm, ho txhim khu kev tuav
Cobalt nthuav tawm zoo wettability nrog pob zeb diamond ntawm qhov kub thiab txias dua li hlau lossis tooj liab. Thaum lub sij hawm kub - xovxwm sintering, cobalt nruj nreem kaw cov pob zeb diamond hais, tsim ib tug robust interfacial daim ntawv cog lus uas zoo tiv thaiv pob zeb diamond poob ntxov ntxov.
Raws li cov xwm txheej zoo ib yam, cobalt-raws li formulations tsis tshua muaj "pob zeb diamond shedding," cia lub pob zeb diamond siv tag nrho nws cov peev xwm txiav thiab txuas ntxiv lub neej ntawm cov cuab yeej. Thaum ua ke nrog titanium -coated pob zeb diamond, cov nyhuv interfacial bonding yog ntxiv txhim kho.

2. Ntsuas matrix hardness, hnav tsis kam, thiab cuam tshuam toughness (Cobalt qhov zoo tshaj plaws tshwj xeeb tshaj plaws)
Hlau hmoov muaj siab hardness tab sis nruab nrab toughness; tooj liab hmoov muaj zoo toughness tab sis tsis hnav tsis kam;
Cobalt ua rau tib lub sijhawm ua tiav ntawm kev hnav zoo heev thiab cuam tshuam toughness.

• Kev nce qib cobalt cov ntsiab lus txhim kho matrix hnav tsis kam, ua kom nws tiv taus kev sib tsoo tsis tu ncua tiv thaiv quartz aggregates thiab pob zeb nyuaj;
• Tsis zoo li siab - hlau formulations, nws tsis dhau nkig; Yog li, ntu thiab sib tsoo blocks tsis tshua muaj peev xwm tawg lossis poob cov hniav thaum ntsib rebar lossis cuam tshuam tsis sib xws.
• Yog li ntawd, nws yog qhov nyiam cov khoom siv ntxiv rau pawg hauv paus drilling cov khoom thiab cov khoom siv siv rau ntawm cov tawv granite.

 

3. Txhim kho cov yam ntxwv sintering thiab nce matrix ceev
Cobalt muaj cov haujlwm sintering zoo heev; nws ua kom yooj yim ua kua -theem sintering kom ua tiav cov hmoov metallurgical bonding ntawm qhov kub thiab txias thiab tsim cov kev daws teeb meem los txhawb cov matrix.
Cobalt hmoov feem ntau feature flocculent los yog dendritic duab, ua rau muaj zog mechanical interlocking thiab siab ntsuab compact zog. After sintering, the matrix exhibits minimal porosity and a dense, uniform microstructure, ensuring greater batch-to-batch consistency in finished product performance.

 

4. Zoo heev -kub txhua yam khoom; resistant rau siab - kub softening thiab graphitization
Copper-raws li matrices yog yooj yim rau cov yas softening nyob rau hauv qhov kub thiab txias generated los ntawm kev sib txhuam tsis tu ncua; siab- cov qauv hlau zoo li tsim kom muaj cua sov uas txhawb nqa pob zeb diamond graphitization.
Cobalt-raws li matrices khaws lub zog zoo dua ntawm qhov kub thiab txias; lawv tiv thaiv rheological polishing thaum hnyav - lub luag haujlwm txuas ntxiv sib tsoo, yog li txo kev ua haujlwm - ntsej muag passivation thiab slippage. Lawv kuj txo tau siab -kub degradation ntawm pob zeb diamond, ua rau lawv haum rau ntev - khiav mus tas li.

 

5. Kev ruaj ntseg tshuaj zoo; txo slab nto paug
Cobalt oxides tsis tau yooj yim tsim cov xim daj - xim av xeb stains. Piv nrog rau siab -hlau hmoov formulations, muaj tsawg dua kev pheej hmoo ntawm yellow spotting los yog staining thaum ua lub teeb -xim granite los yog lwm yam teeb pom kev zoo- cov ntaub ntawv pob zeb.

 

 

 

yam tseem ceeb los ntsuas qhov kev tsim qauv
1 Cov nqi raw khoom siab

• Cobalt yog lub tswv yim tsis yog- hlau hlau nrog cov nqi ntau tshaj cov hlau lossis tooj liab hmoov. Cov nqi tsim khoom rau tag nrho -cobalt matrices yog qhov siab heev, ua rau lawv tsis tsim nyog rau kev siv dav hauv pawg- kev lag luam engineering consumables; lawv feem ntau ntxiv rau hauv me me raws li kev hloov pauv alloying.

 

2 Cov ntsiab lus cobalt ntau dhau ua rau cov matrix nyuaj dhau thiab txo tus kheej -sharpening

• Raws li qhov sib piv ntawm cobalt nce, matrix hnav tsis kam nce ntau dhau thiab kev siv tus nqi qis dua; qhov no tiv thaiv lub sij hawm raug ntawm cov pob zeb diamond tshiab txiav, ua rau passivation thiab sluggish txiav. tooj liab thiab tin feem ntau ntxiv los kho tus kheej -ntxhiab tus yam ntxwv.

 

3 Ultra-cov hmoov cobalt zoo heev uas ua rau oxidation

• Ultra-cov hmoov cobalt zoo heev reactive thiab oxidizes yooj yim thaum sib cuag nrog huab cua thaum lub sij hawm cia thiab sib tov. Cobalt oxides cuam tshuam metallurgical bonding, ua rau txo cov matrix zog thiab nce porosity; yog li ntawd, kev tsim khoom yuav tsum muaj kev tswj hwm nruj dua ntawm kev sib xyaw ib puag ncig thiab kev tiv thaiv huab cua.

 

 

1. Flocculent electrolytic cobalt hmoov: Cov qauv kev lag luam; Cov yam ntxwv los ntawm qhov chaw tshwj xeeb ntawm qhov chaw, kev ua haujlwm siab sintering, thiab zoo formability. Nws muaj cov dej ntws tsis zoo thiab tsim nyog rau cov pa kub - nias sib tsoo ntu thiab laum cov khoom.
2. Spherical atomized cobalt hmoov: Zoo heev flowability, ua rau nws tau tshaj automated nruam molding ntau lawm kab; Txawm li cas los xij, nws txoj haujlwm sintering qis dua li ntawm electrolytic cobalt.
