Gr2 ERTi-2 titanium xov hlau nrog carburizing nto kho

Kev soj ntsuam ntawm qhov teeb meem ntawm yuav ua li cas carburize nto kho ntawm titanium hlau? Ntshiab titanium yog cov hlau dawb-dawb uas muaj ntau yam zoo heev. Titanium hlau tsim ib qho ruaj khov carbide nrog carbon nrog siab hardness. Kev loj hlob ntawm carbide txheej ntawm titanium thiab carbon yog txiav txim los ntawm tus nqi ntawm diffusion ntawm titanium nyob rau hauv carbide txheej.
Lub solubility ntawm carbon nyob rau hauv titanium yog me me, tag nrho {{0}}.3% ntawm 850X: thiab poob mus txog 0.1% ntawm 600C B Vim yog me me solubility ntawm carbon nyob rau hauv titanium, nto hardening yog yeej xwb tiav. los ntawm cov deposition ntawm titanium carbide txheej thiab nws cov hauv paus forsaken domain. Carburizing yuav tsum tau nqa tawm nyob rau hauv cov xwm txheej ntawm kev tshem tawm cov pa oxygen, vim hais tias lub hardness ntawm lub deg txheej tsim los ntawm kev siv cov feem ntau siv carburizing hmoov rau hlau tiv thaiv carbon monoxide los yog carbon monoxide nto uas muaj oxygen mus txog 2700MPa thiab 8500MPa, thiab qhov muag. Nws flakes tawm yooj yim.
