Kev hloov kho saum npoo ntawm ntshiab titanium pas nrig thiab titanium alloy rods feem ntau suav nrog: nitriding, anodizing, atmospheric oxidation, thiab lwm yam.
1. Nitriding: Tshuaj kho cua sov technologies xws li plasma nitriding, multi-arc ion plating, ion implantation thiab laser nitriding yog siv los ua ib tug golden TIN txheej rau saum npoo ntawm titanium hniav hniav, yog li txhim kho cov hnav tsis kam thiab corrosion kuj ntawm titanium. thiab qaug zog tiv taus. Txawm li cas los xij, thev naus laus zis yog qhov nyuaj thiab cov cuab yeej siv kim, ua rau nws nyuaj rau kev ua tiav kev kho mob hauv kev hloov kho ntawm titanium hniav hniav.
2. Anodizing: Lub tshuab anodizing ntawm titanium rods yog qhov yooj yim heev. Hauv qee qhov kev tshaj tawm oxidizing, nyob rau hauv qhov kev txiav txim ntawm kev siv hluav taws xob, titanium anode tuaj yeem tsim cov yeeb yaj kiab oxide tuab, yog li txhim kho nws cov corrosion kuj, hnav tsis kam, thiab huab cua tsis kam. . Cov electrolyte rau anodizing feem ntau siv H2SO4 thiab acid aqueous tov.
3. Atmospheric oxidation: Titanium rods tuaj yeem tsim cov yeeb yaj kiab tuab thiab cov khoom tsis muaj dej oxide nyob rau hauv qhov chaw kub, uas muaj txiaj ntsig zoo tiv thaiv ob qho tib si kev txhim kho corrosion thiab qhov sib txawv corrosion ntawm titanium. Txoj kev no kuj yooj yim.
Ntshiab titanium rods thiab titanium alloy rods yog ib qho yooj yim rau react nrog cov ntsiab lus xws li O, H, N nyob rau hauv cov huab cua thiab Si, AL, Mg thiab lwm yam nyob rau hauv lub peev ntawm kub kub, tsim ib tug deg pollution txheej nyob rau hauv lub casting. , ua rau nws zoo heev Lub cev thiab tshuaj muaj zog deteriorate, lub hardness nce, lub plasticity thiab elasticity txo, thiab lub brittleness nce.
Qhov ceev ntawm ntshiab titanium rods thiab titanium alloy rods yog me me, yog li lub inertia ntawm kua titanium yog me me thaum ntws. Lub fluidity ntawm molten titanium yog qhov tsis zoo, uas ua rau qis casting txaus tus nqi. Qhov sib txawv ntawm qhov kub thiab txias pwm (300 degrees) yog qhov loj thiab qhov txias yog ceev. Casting yog ua nyob rau hauv ib qho chaw tiv thaiv. Cov teeb meem xws li pores yuav inevitably tshwm sim ntawm qhov chaw thiab sab hauv ntawm titanium castings, uas muaj kev cuam tshuam zoo rau qhov zoo ntawm cov castings.
