Ithagethi ye-Chromium aluminium alloy, njengoba igama liphakamisa, iyithagethi eyenziwe nge-chromium ne-aluminium alloy. Abangane abaningi banelukuluku lokwazi ukuthi leli phuzu lenziwa kanjani. Manje ake ochwepheshe bezobuchwepheshe abavela ku-RSM bethule indlela yokukhiqiza yethagethi ye-chromium aluminium alloy. Izinyathelo zokukhiqiza zimi kanje:
(1) Khetha i-chromium powder enobumsulwa obukhulu kuno-99.5wt% kanye ne-aluminium powder enobumsulwa obukhulu kuno-99.99wt% njengezinto zokusetshenziswa. Ububanzi bezinhlayiyana zokusabalalisa usayizi we-chromium powder kanye ne-aluminium powder yi-100 mesh +200 mesh. Zifake ku-mixer emise okwe-V ngokwesilinganiso esidingekayo, bese ucofa i-mixer iye ezingeni le-10-1pa, ujove i-argon, bese u-vacuum futhi, uphinde izikhathi ezi-3, bese usetha isivinini esingu-10 ~ 30 rpm ukuze uxube izikhathi ezingu-5. ~ Amahora angu-10;
(2) Faka impushana ngemva kokuyixuba ejantshini elibandayo le-isostatic, licofe bese ulivala. Yicindezele ngaphansi kwengcindezi engu-100mpa ~ 300mpa imizuzu engu-10 ~ 20, bese ubeka umzimba oluhlaza ocindezelwe ku-vacuum self extension esithandweni sokushisa esiphezulu se-synthesis ukuze uphendule ngokwakho. Enkambweni yokugeza isithando somlilo, i-vacuum degree iyadingeka ukuze ifinyelele ku-10-3pa ukuthola i-foam chromium aluminium alloy;
(3) Ingxube ye-chromium aluminium emise okwegwebu igaywa ibe yimpuphu engu-200 yengxubevange yengxubevange nge-crusher, bese ingxube ye-alloy powder ifakwa ejakhethini ebandayo ye-isostatic, ivalwe ngemuva kokuhlanza, bese icindezelwa ngaphansi kwengcindezi engu-200mpa ~ 400mpa ngama-30 ~ Imizuzu engama-60 ukuthola i-chromium aluminium alloy billet;
(4) I-aluminium alloy billet ye-chrome ifakwa ebhantshini leladi ukuze kuhlanzwe i-vacuum degassing. Ngemuva kokwelashwa, ijakhethi ye-ladle ifakwa kumshini wokucindezela we-isostatic oshisayo ukuze kutholwe i-chrome aluminium alloy billet. Izinga lokushisa elishisayo lokucindezela i-isostatic liyi-1100 ~ 1250 ℃, ingcindezi ye-sintering ingu-100 ~ 200mpa, futhi isikhathi se-sintering amahora angu-2 ~ 10;
(5) Ingot ye-chromium aluminium alloy yenziwa ngomshini ukuze kutholwe umkhiqizo oqediwe wethagethi yengxube ye-chromium aluminium.
