Tungsten carbide (alupupu lile) ni lẹsẹsẹ ti awọn ohun-ini ti o dara julọ gẹgẹbi lile lile, yiya resistance, agbara to dara ati lile, resistance ooru ati ipata, paapaa lile lile rẹ ati resistance resistance, paapaa ni iwọn otutu ti 500 ℃ O jẹ ipilẹ ko yipada. , ati pe o tun ni lile giga ni 1000 ℃.

Tungsten carbide, awọn paati akọkọ jẹ tungsten carbide ati cobalt, eyiti o jẹ iroyin fun 99% ti gbogbo awọn paati, 1% jẹ awọn irin miiran, nitorinaa a pe ni irin tungsten, ti a tun mọ ni carbide cemented, ati pe o jẹ eyin ti ile-iṣẹ ode oni. .

Tungsten carbide jẹ ohun elo idapọmọra sintered ti o kere ju carbide irin kan.Tungsten carbide, cobalt carbide, niobium carbide, titanium carbide, ati tantalum carbide jẹ awọn paati ti o wọpọ ti irin tungsten.Iwọn ọkà ti paati carbide (tabi alakoso) nigbagbogbo wa laarin 0.2 ati 10 microns, ati awọn oka carbide ti wa ni asopọ papọ nipa lilo ohun elo irin.Irin ti o so pọ jẹ apapọ irin ẹgbẹ irin, ati koluboti ati nickel ni a lo nigbagbogbo.Nitorina, awọn ohun elo tungsten cobalt tungsten, tungsten nickel alloys ati tungsten titanium cobalt alloys.

Tungsten carbide sintering ni lati tẹ awọn lulú sinu òfo, ki o si ooru o sinu kan sintering ileru si kan awọn iwọn otutu (sintering otutu), ki o si pa o fun awọn akoko kan (idaduro akoko), ati ki o si dara o, ki o le gba. iṣẹ ti o fẹ ti ohun elo irin tungsten.
