Kev hloov kho saum npoo ntawm ntshiab titanium rods thiab titanium alloy rods feem ntau suav nrog: nitriding, anodizing, atmospheric oxidation thiab lwm yam.
1. Nitriding: kev siv plasma nitriding, multi-arc ion plating, ion implantation thiab laser nitriding thiab lwm yam kev kho cua sov tshuab, tsim ib tug Golden daj TIN plating txheej rau saum npoo ntawm titanium hniav hniav, yog li txhim kho cov hnav tsis kam, corrosion kuj thiab qaug zog kuj ntawm titanium. Txawm li cas los xij, thev naus laus zis nyuaj thiab cov cuab yeej siv kim, yog li nws nyuaj rau ua tiav qhov kev hloov kho saum npoo rau titanium hniav hniav kom ua tau raws li kev kho mob.
2. Anodic oxidation: anodic oxidation tshuab ntawm titanium rods yog yooj yim dua, nyob rau hauv ib co oxidizing xov xwm, nyob rau hauv qhov kev txiav txim ntawm cov ntaub ntawv voltage, titanium anode tuaj yeem tsim cov oxide zaj duab xis tuab, yog li txhim kho nws cov corrosion kuj thiab hnav tsis kam, huab cua tsis kam. Cov electrolyte rau anodic oxidation feem ntau siv H2SO4 thiab kua qaub aqueous tov.
3. Atmospheric oxidation: titanium rods nyob rau hauv qhov kub thiab txias huab cua tuaj yeem tsim cov khoom tuab ntawm cov khoom tsis muaj dej oxide zaj duab xis, tag nrho corrosion ntawm titanium, interstitial corrosion yog zoo, txoj kev yog kuj yooj yim.
Ntshiab titanium rods thiab titanium alloy rods ntawm qhov kub thiab txias yog ib qho yooj yim rau hnov mob nrog cov ntsiab lus xws li O, H, N thiab lwm yam nyob rau hauv cov huab cua thiab embedded cov ntaub ntawv nyob rau hauv lub Si, AL, Mg thiab lwm yam ntsiab lus, tsim ntawm deg paug txheej rau Qhov saum npoo ntawm cov casting, kom nws cov khoom zoo heev ntawm lub cev thiab tshuaj lom neeg tsis zoo, hardness, plasticity, elasticity, brittleness nce.
Ntshiab titanium rods thiab titanium alloy rods ceev yog me me, yog li cov ndlwg ntawm titanium kua inertia yog me me, molten titanium mobility tsis zoo uas ua rau tsawg casting txaus tus nqi. Casting kub thiab casting kub sib txawv (300 degrees), txias ceev, casting nyob rau hauv ib tug tiv thaiv cua, titanium casting nto thiab sab hauv xws li porosity yog inevitable, lub casting zoo muaj ib tug zoo heev cuam tshuam.
Yog li ntawd, kev kho deg ntawm ntshiab titanium rods thiab titanium alloy rods yog ib qho tseem ceeb dua piv nrog rau lwm yam titanium khoom, vim lub cim lub cev thiab tshuaj zog ntawm titanium pas nrig, xws li me me thermal conductivity, deg hardness, raws li zoo raws li tsis tshua muaj modulus ntawm elasticity. , viscous, tsis tshua muaj conductivity, yooj yim rau oxidize, thiab lwm yam., cov kev kho deg ntawm titanium tau coj ib tug loj deal ntawm cov teeb meem nyob rau hauv kev siv cov pa kev kho deg txoj kev yog ib qho nyuaj rau ua tiav cov txiaj ntsig zoo tshaj plaws. Cov txheej txheem tshwj xeeb thiab kev ua haujlwm yuav tsum tau siv.
