Kwambara ikirere no gukuraho Cobalt ya PDC

I. Kwambara ubushyuhe no gukuraho cobalt ya pdc

Mu kaga gakomeye ka PDC, Cobalt ikora nk'umusemburo wo guteza imbere guhuza diyama na diyama, no gutuma amenyo ya PDC akwiranye na peteroli ya peteroli hamwe no kurwanya cyane,

Diyama yo kurwanya ubushyuhe ni nkeya. Mugitutu cyikirere, ubuso bwa Diamond irashobora guhindura ubushyuhe hafi 900 ℃ cyangwa irenga. Mugihe cyo gukoreshwa, PDC gakondo zikunda gutesha agaciro 750 ℃. Iyo ucukura kunyuramo cyane kandi bikurura ibibuye bigoye kandi bishobora kugera kuri ubu bushyuhe kubera ubushyuhe bworoshye, nubushyuhe ako kanya (ni ukuvuga ubushyuhe bwibanze bwo gushonga).

Ugereranije na diyama nziza, bitewe no kuba hari codalt, diyama yihindura kubishushanyo ku bushyuhe bwo hasi. Nkigisubizo, kwambara kuri diyama biterwa no gushushanya biturutse kubushyuhe bwaho. Byongeye kandi, uburyo bwo kwagura ubushyuhe bwa coebal burenze urugero bwa diyama, kuburyo bukabije, guhuza ibinyampeke bya diyama birashobora guhungabana no kwaguka kwa coabant.

Mu 1983, abashakashatsi babiri bakoze ubuvuzi bwa diyama ku buso bw'ibice bya diyama isanzwe ya PDC, bikaba byanze bikunze imikorere ya meme ya PDC. Ariko, iyi guhanga ntabwo yakiriye ibitekerezo bikwiye. Ntabwo kugeza nyuma ya 2000 ibyo, usobanukiwe neza ibice bya diyama ya PDC, abatanga ibikoresho bya PLC batangiye gukurikiza ubu buhanga muri Amenyo ya PDC ikoreshwa mu gukiniraho. Amenyo yavuwe nubu buryo bukwiye kugirango agaragare cyane kubambara cyane hamwe no kwambara imashini zikomeye kandi bikunze kuvugwa nka "amenyo".

Ibibyitwa "de-co-collat" bikozwe muburyo gakondo bwo gukora PDC, hanyuma hejuru yumurima wa diyama wibizwa muri acide ikomeye kugirango ukureho icyiciro cya cose ukoresheje inzira ya aside. Ubujyakuzimu bwa cobalt yo gukuraho burashobora kugera kuri microne bagera kuri 200.

Ikizamini Cyinshi cyambara cyakozwe kumenyo abiri ya PDC (imwe muriyo yari yarafashwe ya codalt yo gukuraho amakariso kuri diyama). Nyuma yo gukata 5000m ya granite, wasangaga igipimo cyambara cyambaye PDC yakuweho PDC yatangiye kwiyongera. Ibinyuranye, PDC yakuweho PDC yabujije umuvuduko uhagaze neza mugihe ugabanye hafi 15.000m.

2. Uburyo bwa PDC

Hariho uburyo bubiri bwuburyo bwo kumenya amenyo ya PDC, aribyo bipimisha ibizamini byangiza kandi bitangiza.

1. Kwipimisha kwangiza

Ibi bizamini bigamije kwigana imiterere yamanutse nkuko bishoboka gusuzuma imikorere yo gutema amenyo mubihe nkibi. Uburyo bubiri bwingenzi bwo kwipimisha bwangiza ni ugushaka ibizamini byo kurwanya no guteza imbere ingaruka.

(1) Kwambara ikizamini cyo kurwanya

Ubwoko butatu bwibikoresho bikoreshwa mugukora ibizamini byo kurwanya PDC:

A. Lartical Lathe (VTL)

Mugihe cyo kwipimisha, ubanza gukosora PDC bit kuri VTL kuri VTL hanyuma ushire icyitegererezo cya rock (mubisanzwe granite) kuruhande rwa PDC bit. Noneho uzenguruke urutare ruzengurutse lathe axis kumuvuduko runaka. PDC igabanya ibintu murutare yimbitse hamwe nubujyakuzimu bwihariye. Mugihe ukoresheje granite yo kwipimisha, ubu bujyakuzimu muri rusange ntabwo buri munsi mm 1. Iki kizamini gishobora kuba cyumye cyangwa gitose. Muri "gukata VTL. Ubushyuhe bwose bwahagaritswe yinjira muri PDC, kwihutisha inzira yo gushushanya ya diyama. Ubu buryo bwo kwipimisha butanga umusaruro mwiza mugihe basuzuma PDC bits mu bihe bisaba igitutu kinini cyangwa umuvuduko mwinshi.

Ikizamini cya "Wet VTL" kivuga ubuzima bwa PDC muburyo buciriritse mugukonjeza amenyo cyangwa umwuka mugihe cyo kwipimisha. Kubwibyo, isoko nyamukuru yindege yiki kizamini ni ugusya icyitegererezo cya rock kuruta ibintu bishyuha.

B, larizontal

Iki kizamini nacyo gikorwa na granite, kandi ihame ryikizamini ni kimwe na VTL. Igihe cyibizamini ni iminota mike gusa, kandi ihungabana ryubushyuhe hagati ya granite na PDC ni gake cyane.

Ikizamini cya Granite cyakoreshejwe nabatanga ibikoresho bya PDC bizatandukana. Kurugero, ibipimo by'ibizamini byakoreshejwe na Synthetic Corporation na Di sosiyete yo muri Amerika ntabwo ari kimwe, ariko bakoresha ibikoresho bimwe kubigeragezo byinshi hamwe nicyubahiro gito cyane cya 190MPA.

C. Ikigereranyo cya Abrosion gipima igikoresho

Mu bihe byagenwe, igice cya diyama cyakoreshwa mu gihe cya silicon carbide gisya uruziga, kandi igipimo cy'ikigereranyo cyo gusya no kwambara PDC gifatwa nk'igipimo cya PDC, kitwa kwambara igipimo cyambara.

(2) Ikizamini cyo kurwanya ingaruka

Uburyo bwo kwipimisha ingaruka bikubiyemo kwishyiriraho amenyo ya PDC kumurongo wa dogere 15-25 hanyuma ugata ikintu muburebure runaka kugirango ushireho igice cya diyama kumenyo ya PDC ganye. Uburemere nuburebure bwikintu kigwa cyerekana urwego rwingufu zabayeho nimenyo yikizamini, bushobora kwiyongera buhoro buhoro impaso 100. Buri iryinyo rishobora kwigira ingaruka inshuro 3-7 kugeza ridashobora kugeragezwa cyane. Mubisanzwe, byibuze ingero 10 ya buri bwoko bwamarto igeragezwa kuri buri cyiciro. Kubera ko hari urutonde rwinyoni rwo guhangana ningaruka, ibisubizo byikizamini kuri buri rwego rwurwego ni ahantu hagereranijwe ka diyama nyuma yingaruka kuri buri menyo.

2. Ibizamini byangiza

Ubugenzuzi bukoreshwa cyane budasenya (usibye ubugenzuzi bugaragara kandi bwa microscopique) ni scanic ultrasonic scannic (Cscan).

C Ikoranabuhanga rya Scanning rirashobora kumenya inenge nto kandi tumenye ahantu hamwe nubunini bwinebwe. Mugihe ukora iki kizamini, ubanza ushyire iryinyo rya PDC mumazi, hanyuma usigeze ikipe ya Ultrasonic;
