Ngā Mata o te Tungsten Carbide
Mā te whiriwhiri i te taumata tino pai, ka taea te whakakoi i ngā mata o te karāhe tungsten iti-maikoron ki te mata heu, me te kore e pakarukaru te āhua e pā ana ki te karāhe tikanga. Ahakoa kāore i te ātete ki te ru pērā i te maitai, he tino ātete te karāhe ki te kakahu, me te pakeke e rite ana ki te Rc 75-80. Ka taea te tumanako kia 50X te roa o te ora o ngā mata o ngā maitai mata tikanga mēnā ka karohia te pakaru me te pakaru.
Pērā i te kōwhiringa maitai, he tukanga uaua te whiriwhiri i te taumata tino pai o te tungsten carbide (WC) e uru ana ki ngā kōwhiringa kua whakaitihia i waenga i te ātete kakahu me te pakari/ātete ru. Ka hangaia te tungsten carbide sima mā te sintering (i te pāmahana teitei) he ranunga o te paura tungsten carbide me te paura cobalt (Co), he konganuku ngawari e mahi ana hei "here" mō ngā matūriki tungsten carbide tino pakeke. Kāore te wera o te tukanga sintering e uru ki te tauhohenga o ngā wāhanga e rua, engari ka meinga te cobalt kia tata ki te āhua wai, ka rite ki te matrix kāpia e kapi ana mō ngā matūriki WC (kāore e pāngia e te wera). E rua ngā tawhā, arā, ko te ōwehenga o te Cobalt ki te WC me te rahi o te matūriki WC, e whakahaere nui ana i ngā āhuatanga rauemi papatipu o te wahi "tungsten carbide sima" ka puta.
Mā te tohu i te rahi o te matūriki WC nui me te ōrau nui o te Cobalt ka puta he wāhanga tino ātete ki te ru (me te kaha pānga nui). Ko te rahi o te kōpura WC (nō reira, ko te nui ake o te mata WC me pania ki te Cobalt) me te iti ake o te Cobalt e whakamahia ana, ka pakeke ake, ka ātete hoki te wāhanga hua ki te kakahu. Hei whiwhi i te mahi pai rawa atu mai i te carbide hei rauemi mata, he mea nui kia karohia ngā pakaru o te taha i puta mai i te pakaru, i te whati rānei, me te whakarite i te ātete kakahu pai rawa atu.
Hei mahi whaihua, ko te hanga i ngā mata tapahi tino koi, he koki koi, me whakamahi he kāpira pai mō ngā mahi mata (hei ārai i ngā kohao nui me ngā mata taratara). I te mea he 1 maikorona te rahi toharite o te mata, iti iho rānei, ka nui te pānga o te mahi mata kāpira ki te % o te Kobalt me te āhua o te mata kua tohua. Ko ngā mahi tapahi e whakamahi ana i ngā kawenga ru reo-waenga ki te teitei, he pai ake te whakatau mā te tohu i te 12-15 ōrau o te Kobalt me te āhua o te mata he koki taha whakauru tata ki te 40º. Ko ngā mahi e whakamahi ana i ngā kawenga māmā ake, ā, e whakapau kaha ana ki te roa o te ora o te mata he pai mō te kāpira kei roto he 6-9 ōrau o te kopara, ā, he koki taha whakauru kei roto i te awhe o te 30-35º.
Kei te rite tonu a HUAXIN CARBIDE ki te āwhina i a koe ki te whakatutuki i te taurite tino pai o ngā āhuatanga e taea ai e koe te whiwhi i te mahi tino pai mai i ō mata carbide.
He maha ngā mata tapahi heu carbide kua whakakiia ki te HUAXIN CARBIDE.
