Ukuqaliswa kwezinto zokufudumeza ivacuum sintering eziko

Indlela yokudlulisa ubushushu yesixhobo sokufudumeza somlilo we-vacuum sintering kwi-workpiece yahlukile kulowo wesiqhelo sombane wokufudumeza isithando somlilo, esisekelwe ikakhulu kwi-radiation transfer heat. Izinto zokufudumeza ikakhulu ziquka i-nickel chromium, imolybdenum yobushushu obuphezulu, igraphite kunye nebhanti yegraphite (ipleyiti), ibhanti letungsten kunye ne-tungsten mesh:

(1) I-Ni-Cr isetyenziswa ikakhulu kwiziko elibushushu bungaphantsi kwe-1000℃;

(2) Imolybdenum yobushushu obuphezulu ingafakwa kwiziko lomlilo elingaphantsi kwe-1600 ℃;

(3) I-graphite kunye ne-graphite tape (ipleyiti) ingasetyenziselwa kwisithando somlilo esingaphantsi kwe-2300 ℃;

(4) Ibhanti yeTungsten kunye ne-tungsten mesh ingasetyenziswa kumzimba wesithando somlilo ongaphantsi kwe-2400 ℃.

Ukukhethwa kwezinto ezifudumalayo kugxininiswa ikakhulu ngukushisa kwe-sintering, iimpawu zomzimba kunye neekhemikhali zemveliso.
