Tantalum Carbide Particles

Qhov ceev yog 14.3g / cm3. Insoluble nyob rau hauv dej, insoluble nyob rau hauv inorganic acid, soluble nyob rau hauv sib xyaw acid ntawm hydrofluoric acid thiab nitric acid, thiab decomposable. Muaj zog antioxidant muaj peev xwm, yooj yim rau yaj thiab decomposed los ntawm poov tshuaj pyrosulfate. High conductivity, tsis kam ntawm 30Ω ntawm chav tsev kub, qhia superconductivity. Siv hauv cov hmoov hlau metallurgy, txiav cov cuab yeej, nplua ceramics, tshuaj vapor deposition, cemented hnav-resistant alloy cov cuab yeej, cov cuab yeej, pwm, hnav-resistant, thiab corrosion-resistant structural seem additives, txhim kho lub toughness ntawm alloys. Lub cev sintered ntawm tantalum carbide qhia tau hais tias golden daj thiab tuaj yeem siv los ua kev kho kom zoo nkauj saib.

Tantalum carbide particles muaj qhov zoo ntawm lub zog siab, siab hardness, thiab zoo ntub dej nrog cov matrix, ua rau lawv siv dav hauv aerospace, metallurgy, tsev cov ntaub ntawv, hluav taws xob, hydropower, mining, thiab lwm yam kev lag luam raws li theem ob particle-reinforced hlau. matrix composites, thiab tau ua tiav cov txiaj ntsig kev siv tau zoo. Cov lus tshaj tawm carbide feem ntau suav nrog tungsten carbide (WC), titanium carbide (TiC), niobium carbide (NbC), thiab vanadium carbide (VCp), thaum tantalum, lub caij ntawm tib tsev neeg ntawm vanadium hlau thiab niobium, yog tsawg kawm.

Tantalum carbide (TaC) particles muaj qhov zoo ntawm lub siab melting point (3880 degree), siab hardness (2100HV0.05), zoo tshuaj stability, muaj zog hluav taws xob thiab thermal conductivity, thiab lwm yam, tab sis vim lawv cov nqi thiab lwm yam teeb meem, cov lus ceeb toom tsuas yog siv rau nickel-based, aluminium-based, thiab lwm yam substrates. Chaw et al. siv lub tshuab laser cladding los npaj cov nickel-based reinforced tantalum carbide deg composites, thiab cov txiaj ntsig tau pom tias qhov hardness ntawm cov khoom no tau nce siab dua li cov npib tsib xee ntshiab, thiab tus nqi hnav tau qis dua li cov hlau hardened. Yus et al. tau kawm txog kev sib raug zoo ntawm cov kev taw qhia kev sib zog ntawm cov nickel-based, chromium-based, thiab aluminium-based reinforced tantalum carbide nyob rau hauv situ thiab nws cov microstructure nyob rau hauv high-temperature gradients, thiab cov txiaj ntsig tau pom tias nrog kev nce ntawm solidification npaum li cas, cov qauv txheej txheem. hloov, thiab qhov ntim feem ntawm tantalum carbide kuj hloov nrog kev hloov ntawm solidification tus nqi. Wang Wenli et al. siv laser cladding technology los npaj ib qho in-situ TaC particle-reinforced npib tsib xee-raws li kev sib xyaw txheej rau saum npoo ntawm A3 steel, thiab cov txiaj ntsig tau pom tias nyob rau hauv cov txheej txheem tsim nyog, TaC particle-reinforced nickel-based composite txheej tau tsim tau zoo, Qhov saum npoo yog du, thiab txheej thiab cov matrix pom zoo metallurgical bonding. Txawm li cas los xij, txoj kev tshawb fawb ntawm cov tiam neeg ntawm TaC los ntawm lub hauv paus steel tsis tshua muaj tshwm sim. Yog li ntawd, txoj kev ntawm qhov chaw ceramic particle-enhanced hlau-raws li composite tau siv nyob rau hauv qhov kev sim no. Tib lub sijhawm, TaC hais tau raug xaiv raws li theem thib ob particle reinforcement theem. Cov txheej txheem micromorphology thiab cov tshuaj tiv thaiv ntawm TaC hais tau txhawb nqa hauv situ reinforced hlau matrix composites tau txheeb xyuas.
