Chromium aluminium alloy phiaj, raws li lub npe qhia, yog lub hom phiaj ua los ntawm chromium thiab aluminium alloy. Ntau tus phooj ywg xav paub heev txog yuav ua li cas lub hom phiaj no. Tam sim no cia cov kws tshaj lij los ntawm RSM los qhia txog cov txheej txheem tsim khoom ntawm chromium aluminium alloy phiaj. Cov txheej txheem tsim khoom yog raws li nram no:
(1) Xaiv cov hmoov chromium nrog purity ntau dua 99.5wt% thiab txhuas hmoov nrog purity ntau dua 99.99wt% raws li raw cov ntaub ntawv. Qhov loj me me ntawm chromium hmoov thiab txhuas hmoov yog 100 mesh + 200 mesh. Muab lawv tso rau hauv V-shaped tov khoom raws li qhov yuav tsum tau ua, ces nqus lub tov rau 10-1pa theem, txhaj argon, ces nqus tsev dua, rov ua dua rau 3 zaug, thiab tom qab ntawd teem lub ceev ntawm 10 ~ 30 rpm los sib tov rau 5. ~ 10 teev;
(2) Muab cov hmoov tom qab sib tov rau hauv lub tsho txias isostatic nias, nqus nws thiab kaw nws. Nias nws nyob rau hauv lub siab ntawm 100mpa ~ 300mpa rau 10 ~ 20 feeb, thiab tom qab ntawd muab lub pressed ntsuab lub cev nyob rau hauv lub nqus nws tus kheej extension siab kub synthesis cub rau nws tus kheej extension cov tshuaj tiv thaiv. Nyob rau hauv cov txheej txheem ntawm lub tshuab ntxhua khaub ncaws, lub tshuab nqus tsev kawm ntawv yuav tsum ncav cuag 10-3pa kom tau ua npuas ncauj chromium aluminium alloy;
(3) Cov ua npuas ncauj zoo li chromium aluminium alloy yog crushed rau hauv 200 mesh alloy hmoov nrog crusher, thiab tom qab ntawd cov hmoov hlau yog muab tso rau hauv lub tsho txias isostatic nias, kaw tom qab nqus, thiab nias hauv qab lub siab ntawm 200mpa ~ 400mpa rau 30 ~ 60 feeb kom tau txais chromium aluminium alloy billet;
(4) Lub chrome aluminium alloy billet yog muab tso rau hauv lub tsho ladle rau lub tshuab nqus tsev degassing. Tom qab kev kho mob, lub tsho ladle yog muab tso rau hauv cov khoom siv kub isostatic nias rau kub isostatic nias sintering kev kho kom tau txais chrome aluminium alloy billet. Qhov kub isostatic nias sintering kub yog 1100 ~ 1250 ℃, sintering siab yog 100 ~ 200mpa, thiab lub sij hawm sintering yog 2 ~ 10 teev;
(5) Lub chromium aluminium alloy ingot yog machined kom tau cov khoom tiav ntawm chromium aluminium alloy phiaj.
