I te whanaketanga o te pūngao waiariki o te tau 2025, ko te hangarau "rewa (tangohia te cobalt)" te mea nui rawa atu i ngā au rapu ahumahi, e akiakihia ana e te hiahia mō ngā taputapu keri pāmahana teitei, ātete ki te kakahu. Ko Wuhan Ninestones Superabrasives Co., Ltd., he paionia tapahi PDC, e hanga hou ana i te tango waiariki me te hangarau rewa matatau, me teNiho Tuanui Taimana MR1613A6he kaiwhakahaere keri hōhonu e whai pānga nui ana ki te huringa o te kēmu.
Ko ngā kaupapa waiariki hohonu pēnei i te EGS me te toka wera maroke e hiahia ana ki ngā taputapu hei tu atu i ngā pāmahana o raro i te poka 150–200°C. Ko ngā kaitapahi PDC tuku iho e whakamahi ana i te cobalt hei whakakorikori, e tere ake ai te whakakāwhata taimana i raro i te wera, ka puta te pirau wera me ngā pakaru pinepine. Ko te tukanga rewa a Wuhan Ninestones e tango tika ana i te cobalt mai i te paparanga taimana, e whakaoti ana i tēnei take matua.
Ko te tikanga matū pehanga motuhake a te kamupene e whakamahi ana i tētahi pūnaha matū matū whakakotahi (HCl, waikawa whanariki, waikawa Lewis) i te 160°C me te 0.8MPa, e neke atu ana i te 580μm te tango cobalt i roto i ngā hāora 72. Mā tēnei ka whakakorea te whakakāwhata e peia ana e te cobalt, ka whakaitihia hoki te koretake o te whānui wera, ka tino whakanuia te pumau wera.
Mā te whakauru i tēnei hangarau, kaNiho Tuanui Taimana MR1613A6ka mau tonu ki te 1200°C—he nui atu i te rohenga 750°C o ngā PDC tuku iho. I whakaatuhia e ngā whakamātautau mara i roto i te puna waiariki 187°C o Utah he pumau tana mahi mō ngā hāora 120+, ki te 45 hāora mō ngā kaitapahi tuku iho, me te tapahi i te auau takahi me te pai o te hiki mā te 30%.
Ko te hanganga ahurei o te MR1613A6 Diamond Ridge Tooth e arotahi ana ki te kaha tapahi kia pai ake ai te pakaru o te toka, ā, ka mau tonu te āhua o te paparanga taimana kua rewa i raro i te wera nui me te pānga. He mea tino pai mō te whakawhiti i ngā hanganga waiariki ngohengohe-mārō, ka whakaitihia te pakaru, ka roa ake te ora o te mata keri. Mā te QC pakari (ngā whakamātautau kakahu VTL, ngā tātari pānga) ka whakarite kia rite tonu te mahi.
E hangai ana ki te matapae mākete taputapu waiariki o te ao e $31B mō te tau 2025, me te tautokona hoki e ngā kaupapa here i te US me ngā whenua whakamātautau EGS 15+, ka tutuki i te hangarau rewa a Wuhan Ninestones ngā hiahia whanaketanga nui me te whakaiti i ngā tapuwae waro.
E kī ana ngā tohunga ka whakaitihia e tēnei putanga hou ngā arai waiariki hohonu. Ko te pono o te MR1613A6 Diamond Ridge Tooth i te pāmahana tino teitei te pūtake o te hokohoko, me te whakatairanga i ngā whakahekenga utu e hiki ake ai te waiariki ki te pūtake pūngao ma. Me te 30 ngā patent me te whai wāhi mai o te CIPPE, kei te whakamahere a Wuhan Ninestones ki te arotau i teNiho Tuanui Taimana MR1613A6me te whakawhānui ake i ana tono.
I te ngaru waiariki o te tau 2025, ka whakatairangahia e te hangarau PDC rewa a Wuhan Ninestones te whai huatanga. Ko te ātete kore e taea te whakataurite ki te wera me te kakahu o te MR1613A6 Diamond Ridge Tooth ka whakamana i te keri pumau me te whai hua, ka whakatairanga i te whakawhiti pūngao ma o te ao i te mea ko te kamupene te kaiārahi i te auahatanga PDC mō te tipu pūngao pumau.
