Titanium yog nquag hnov mob nrog cov ntsiab lus xws li O, H, N hauv huab cua thiab Si, Al, Mg nyob rau hauv cov khoom siv embedded ntawm qhov kub thiab txias, ua rau cov kab mob sib kis ntawm qhov chaw ntawm qhov casting, ua rau lub cev tsis zoo thiab tshuaj lom neeg. , nce hardness, txo plasticity, elasticity, thiab nce brittleness.
Qhov ntom ntawm titanium yog me me, yog li qhov inertia ntawm titanium kua ntws yog me me, thiab cov dej tsis zoo ntawm molten titanium ua rau qis casting tus nqi. Qhov ntsuas kub thiab pwm qhov sib txawv (300 degree) yog qhov loj, thiab qhov txias yog ceev. Casting yog nqa tawm nyob rau hauv ib tug tiv thaiv huab cua, thiab tsis xws luag xws li pores yog inevitable nyob rau saum npoo thiab sab hauv ntawm titanium castings, uas zoo heev cuam tshuam rau qhov zoo ntawm cov castings.
Yog li ntawd, kev kho mob saum npoo ntawm titanium castings yog qhov tseem ceeb dua piv rau lwm cov khoom siv kho hniav. Vim yog lub cev thiab tshuaj lom neeg lub cev ntawm titanium, xws li thermal conductivity, deg hardness, thiab elastic modulus, siab viscosity, tsis tshua muaj conductivity, thiab oxidation yooj yim, nws coj teeb meem loj rau kev kho deg ntawm titanium. Cov txheej txheem kho saum npoo yog qhov nyuaj kom ua tiav cov txiaj ntsig zoo. Cov txheej txheem tshwj xeeb thiab kev ua haujlwm yuav tsum tau siv.
Kev kho mob tom qab ntawm castings tsis yog tsuas yog kom tau txais ib qho chaw du thiab ci ntsa iab, txo qhov sib xyaw thiab adhesion ntawm cov khoom noj thiab cov quav hniav, tswj qhov sib npaug ntawm tus neeg mob lub qhov ncauj microbiota, tab sis kuj ua rau kom muaj kev zoo nkauj ntawm cov hniav hniav; Qhov tseem ceeb tshaj, los ntawm cov txheej txheem kev kho saum npoo thiab kev hloov kho no, cov khoom nto thiab qhov tsim nyog ntawm cov castings tuaj yeem txhim kho, thiab lub cev thiab tshuaj lom neeg ntawm cov hniav, xws li hnav tsis kam, corrosion resistance, thiab kev ntxhov siab qaug zog, tuaj yeem txhim kho.
