Ikozwe muri Carbide ya sima

Carbide ya sima ikozwe mukuvanga karbide ya tungsten na cobalt mukigereranyo runaka, ikanda muburyo butandukanye, hanyuma igacumura.Ubu buryo bwo gucumura bukorerwa mu itanura rya vacu.Yacuzwe mu itanura rya vacuum ku bushyuhe bwa dogere selisiyusi 1,300 kugeza 1.500.

Akabari kihariye

Gukora ibishishwa bikomeye ni ugukanda ifu muri bilet, hanyuma ukayishyushya mu itanura ryashyushya ubushyuhe runaka (ubushyuhe bwo gucumura), hanyuma ugakomeza igihe runaka (gufata umwanya), hanyuma ugakonja, kugirango ubone imikorere isabwa ya ibikoresho bikomeye.

Inzira ya sima ya karbide irashobora kugabanywamo ibice bine byingenzi:

1: Gukuraho ibyashizweho na progaramu yo kurasa mbere, muriki cyiciro umubiri wacumuye uhinduka kuburyo bukurikira:

Kuvanaho ibumba, mugihe cyambere cyo gucumura hamwe no kuzamuka kwubushyuhe, agent ibumba buhoro buhoro kubora cyangwa guhumeka, ukuyemo umubiri wacumuye, icyarimwe, umukozi wo kubumba byinshi cyangwa bike kumubiri wacumuye karburizasi, amafaranga ya carburizing azahinduka hamwe n'ubwoko bwa molding agent, umubare hamwe nuburyo butandukanye bwo gucumura.

Ubuso bwa oxyde yifu yifu iragabanuka.Ubushyuhe bukabije, hydrogen irashobora kugabanya okiside ya cobalt na tungsten.Niba igikoresho cyo gukora cyakuweho mu cyuho kandi kigacumura, imyuka ya karubone-ogisijeni ntabwo ikomeye.Guhangayikishwa no guhuza ibice byifu bigenda bikurwaho buhoro buhoro, ifu yicyuma ihuza itangira gukira no kongera gukora, gukwirakwiza hejuru bitangiye kugaragara, kandi imbaraga zumwanya ziratera imbere.

2: icyiciro gikomeye cyo gucumura (800 ℃ - ubushyuhe bwa eutectic)

Ku bushyuhe mbere yo kugaragara kwicyiciro cyamazi, usibye gukomeza inzira iboneka murwego rwabanjirije iki, reaction ikomeye no gukwirakwizwa birakomera, imigendekere ya plastike irazamuka, kandi umubiri wacumuye bigaragara ko ugabanuka.

3: icyiciro cyamazi yo gucumura (ubushyuhe bwa eutectic - ubushyuhe bwa sinter)

Iyo hari icyiciro cyamazi mumubiri wacumuye, kugabanuka kurangira vuba, hanyuma inzibacyuho ya kirisiti ibaho, ikora microstructure yibanze nuburyo bwimvange.

4: icyiciro cyo gukonjesha (ubushyuhe bwo gucumura - ubushyuhe bwicyumba)

Kuri iki cyiciro, microstructure hamwe nicyiciro cyibigize amavuta ahinduka hamwe nuburyo butandukanye bwo gukonjesha, bushobora gukoreshwa mu gushyushya imiti ya karbide ya sima kugirango itezimbere imiterere yumubiri nubukanishi.
