Coated carbide cov cuab yeej muaj cov txiaj ntsig hauv qab no:
(1) Cov txheej txheej ntawm txheej txheej ntawm cov txheej saum npoo muaj qhov nyuaj heev thiab hnav tsis kam. Piv nrog uncoated cemented carbide, yog coated cement, yog nws tuaj yeem nce cov cuab yeej lub neej ntawm tib lub zog ceev.
(2) Cov coefficient ntawm kev sib txhuam ntawm cov txheej txheem coated thiab cov khoom siv ua yog me me. Piv nrog rau uncoated cemented carbide, lub zog txiav ntawm coated coulation yog txo rau qee yam, thiab cov txheej txheem ua haujlwm zoo dua yog qhov zoo dua.
(3) Vim cov kev ua tau zoo zoo, tus coated carbide riam muaj cov versatility zoo dua thiab dav ua daim ntawv thov ntau yam. Feem ntau cov qauv siv ntawm kev tso cai carbide txheej yog qhov kub siv tshuaj kub vapor deposition (HTCVD). Ntshav Tshuaj Vapor Deposition (PCVD) yog siv los ua rau lub ntsej muag ntawm cov khoom noj carbide.
Cov Hom Txheej Txheem Ntawm Kev Ntseeg Carbide Milling Cutters:
Qhov peb feem ntau cov txheej txheej txheej yog titorium nitride (tin), Titanium Carbonitride (TicN) thiab ticn).
Titanium nitride txheej txheej thiab hnav tsis kam ntawm cov cuab yeej ntawm cov cuab yeej, txo qis kev sib txhuam ntawm ntug, thiab ntev lub neej ntawm lub cuab tam. Titanium Nitride Coated Cov Cuab Yeej yog qhov tsim nyog rau kev ua cov qauv siv qis-alloy thiab stainless hlau.
Qhov saum npoo ntawm Titanium Carbon Strig txheej yog grey, lub hardness yog siab dua li ntawm titanium nitride txheej, thiab cov coj tsis kam zoo dua. Piv nrog rau Titanium Nitride Txheej, Titanium Carbon Tool Rool tuaj yeem ua tiav ntawm cov khoom siv nrawm, feem ntau), thiab cov khoom siv tshem tawm yog siab dua. Titanium carbon teride coated cuab yeej tuaj yeem ua cov txheej txheem ua haujlwm.
Cov titanium aluminide txheej yog grey lossis dub. Nws yog tsuas yog coated nyob rau saum npoo ntawm cov cemented carbide cuab yeej. Nws tseem tuaj yeem ua tiav thaum qhov kev txiav tawm ntawm 800 ℃. Nws yog tsim nyog rau kev nrawm nrawm nrawm txiav. Thaum lub sijhawm qhuav, cov chips hauv qhov chaw txiav tuaj yeem tshem tawm nrog huab cua compressed. Titanium alride yog qhov tsim nyog rau kev ua cov ntaub ntawv loj xws li cov hlau tawv, titanium alloy, npib tsib xee, cam khwb cia hlau thiab siab silicon aluminium alloy.
Daim ntawv thov txheej ntawm cemented carbide milling cutter:
Qhov kev kawm tau ntawm cov cuab yeej siv tshuab kuj tseem muaj kev cuam tshuam hauv kev ua tau zoo ntawm nano-txheej. Txheej ntau pua ntawm cov txheej txheem ntawm cov ntaub ntawv nrog ib tuab ntawm ob peb nanometers ntawm lub cuab yeej hauv paus khoom yog hu ua nano-txheej. The size of each particle of the nano-coating material is very small, so the grain boundary is very long, which has high high-temperature hardness. , Lub zog thiab pob txha tawv tawv.
Lub vickers hardness ntawm nano-txheej tuaj yeem mus txog HV2800 ~ 3000, thiab cov coj tsis zoo los ntawm 5% ~ 50% tshaj li ntawm Micron cov ntaub ntawv. Raws li cov lus tshaj tawm, tam sim no, 62 txheej ntawm cov txheej txheem txheej sib txawv ntawm titanium carbide thiab 400 txheej ntawm tialn-tialn / coated cuab yeej tau tsim.
Piv nrog cov txheej txheem saum toj no, sulfide (Mos2, WS2) co siv rau kev txiav cov highst-zog aluminium alloys thiab qee cov hlau tsis tshua muaj.
