Ukunxiba kwe-thermal kunye nokususwa kwe-cobalt ye-PDC

I. Ukunxiba i-thermal kunye nokususwa kwe-cobalt ye-PDC

Kwinkqubo yenkqubo ye-PDC enkulu ye-PDC, i-Cobhalit isebenza njengokukhuthaza indibaniselwano ngqo yedayimani kunye nedayimane, kwaye iyonke i-PDC ye-PDC iyonke ilungele ubunzima obuphakathi kunye nokunganyangeki kakuhle,

Idayimani yobushushu bulinganiselwe. Phantsi koxinzelelo lwe-thamosmosfic, umphezulu wedayimani unokuguqula amaqondo obushushu ajikeleze i-900 ℃ okanye ngaphezulu. Ngexesha lokusetyenziswa, ii-PDCs zendabuko zidla ngokuphatha gadalala malunga ne-750 ℃. Xa ukrwitshiwe ngamatye anzima kwaye atyhafisa amatye, ii-PDCs zingafikelela ngokulula eli qondo ngenxa yobushushu obunzima, kunye nobushushu be-gotanane (okt, ubushushu obuthile kwinqanaba le-microscopic) benyuka kakhulu, bekukho ngaphezulu kwendawo yokunyibilika kwe-cobat (1495 ° C).

Xa kuthelekiswa nedayimani emsulwa, ngenxa yobukho bomqebali, idayimane iguqula igrafu kumaqondo obushushu asezantsi. Ngenxa yoko, nxiba kwidayimani kubangelwa yigrafiki ebangelwa kukusweleka kwendalo. Ukongeza, ukwandiswa kwe-thermal ukusebenza kwe-cobalt kungaphezulu kakhulu kuneyona dayimani, xa kunjalo ngexesha lokufudumeza, ukuboleka phakathi kwedayimani kunokuphazamiseka kukwanda kweCobabasi.

Ngo-1983, abaphandi ababini benza unyango lwedayimane kumphezulu wezinto ezisemgangathweni zedayimani, ukuphucula ukusebenza kwamazinyo e-PDC. Nangona kunjalo, olu lutshintsho aluzange lufumane ingqalelo. Kwakungekho kude kube ngu-2000 ukuba, ngokuqonda okunzulu kwe-PDC yedayimane, abaqhubi beedrili baqala ukusebenzisa le teknoloji kumazinyo e-PDC asetyenziswa kwi-templing. Amazinyo anyangwa ngale ndlela ilungele ukuqhutywa koqobo kusetyenziswa kakhulu ngokunxiba okubonakalayo kwe-thermal yomatshini kwaye idla ngokubizwa ngokuba ngamazinyo "aphethwe" adred ".

I-De-Cobart "yenziwa ngendlela yesiqhelo yokwenza i-PDC, kwaye ke umphezulu we-diamond yayo untywiliselwa kwi-acid eyomeleleyo ukuze isuse iSigaba seCobalt ye-Acid Etching. Ubunzulu bokukhupha i-cobalt bunokufikelela malunga ne-200 microns.

Uvavanyo lwe-hard oryord lwenziwa ngamazinyo amabini afanayo (enye eya kuthi ga ngoku unyango lwe-cobalt lokususa kwidayimani yedayimani). Emva kokusika i-5000m yeGranite, kwafunyaniswa ukuba ireyithi ye-UN-UN-I-PDC esuswe yi-cobabart yaqala ukukhulisa kabukhali. Ngokwahlukileyo, i-cobabalt-isuswe i-PDC igcine isantya esizinzileyo sokusika ngelixa sisika malunga ne-15000m yelitye.

I-2. Indlela yokufunyanwa kwe-PDC

Zimbini iintlobo zendlela zokufumana amazinyo e-PDC, ezizezi ukuba kuvavanywe abekekayo kunye novavanyo olungezo ntshabalali.

1. Uvavanyo olwenzileyo

Ezi mvavanyo zenzelwe ukulinganisa iimeko zediliya njengenyani kangangoko zinakho ukuvavanya ukusebenza kwamazinyo okusika phantsi kweemeko ezinjalo. Iindlela ezimbini eziphambili zovavanyo olwenzileyo zinxiba iimvavanyo zokunganyangeki kunye neemvavanyo zokunganyangeki kwempembelelo.

(1) nxiba uvavanyo lokunganyangeki

Iindidi ezintathu zezixhobo zisetyenziselwa ukwenza iimvavanyo zokunganyangeki:

A. I-Lather ethe nkqo (vtl)

Ngexesha lovavanyo, qala lungisa i-PDC incinci kwi-vtl lathe kwaye ubeke isampulu yelitye (i-Granite) ecaleni kwe-PDC incinci. Emva koko jikeleza isampulu yelitye ujikeleze i-laxis yesantya esithile. I-PDC inqumle kwisimo selitye kunye nobunzulu obuthile. Xa usebenzisa iGranite yokuvavanywa, oku kubunzulu ukusikeka kungaphantsi kwe-1 mm. Olu vavanyo lunokuba lomile okanye lumanzi. "Ukuvavanywa kwe-vTl eyomileyo," xa i-PDC inqumle etyeni, akukho kuphononongwa; Lonke ubushushu obunethemba eliveliswayo lungena kwi-PDC, ukukhawulezisa inkqubo ye-PARAGRAY yedayimane. Le ndlela yovavanyo ivelisa iziphumo ezigqwesileyo xa kuvavanywa ii-bits ze-PDC phantsi kweemeko ezifuna uxinzelelo oluphezulu lokuqhuba okanye ngesantya esiphezulu.

Uvavanyo "lovavanyo lwe-VTL olumanzi" lubona ubomi be-PDC phantsi kweemeko zokufudumeza ngokumodareyitha ngokupholisa amazinyo e-PDC ngamanzi okanye umoya ngexesha lovavanyo. Ke ngoko, eyona nto iphambili kolu vavanyo kukugaya isampulu yelitye kunokuba kwenzeke into yokufudumeza.

B, i-lathe ethe tyaba

Olu vavanyo lwenziwa neGranite, kwaye umgaqo wovavanyo uyafana ne-VTL. Ixesha lovavanyo yimizuzu embalwa kuphela, kwaye ukothuka kwe-thermal phakathi kwamazinyo amaGranite kunye ne-PDC kunqongophele kakhulu.

Iiparamitha zokuvavanya ezisetyenziswayo ezisetyenziswa ngababoneleli be-PDC yegadi ziya kwahluka. Umzekelo, iiparamitha zovavanyo ezisetyenziswayo ngeQumrhu lokuSebenza kunye neNkulu eUnited States azifani, kodwa zisebenzisa izinto ezithandekayo ze-Polycrystalline ye-Polycrystalline kunye ne-190pa.

C. Isixhobo sokulinganisa sokulinganisa

Phantsi kweemeko ezichaziweyo, umaleko wedayimani we-PDC usetyenziselwa ukugaya ivili le-carbide ye-carbide, kwaye umyinge wereyithi ye-PDC ithathwa njenge-PDC ye-PRDC, ebizwa ngokuba yi-REUTOR ye-PRDC, ebizwa ngokuba yi-REUTO.

(2) Uvavanyo lokunganyangeki kwempembelelo

Indlela yokuvavanywa kwempembelelo ibandakanya ukufakela amazinyo e-PDC kwi-angle ye-15-25 degrees kwaye ilahle into ukusuka kwinqanaba elithile lokubetha idayimani kumazinyo e-PDC ngamazinyo ngokuthe nkqo. Ubunzima kunye nokuphakama kwento ewayo kubonisa inqanaba lamandla empembelelo enamava ovavanyo, enokuthi ngokuthe ngcembe inyukele kwi-100 Joules. Izinyo ngalinye linokuchaphazeleka amaxesha ama-3-7 de kungafuneki kuvavanywe ngakumbi. Ngokubanzi, ubuncinci iisampulu ezili-10 zohlobo ngalunye lwezinyo zivavanywa kwinqanaba ngalinye lamandla. Kuba kukho uluhlu lokungaxhathisi kwamazinyo ukuba nefuthe, iziphumo zovavanyo kwinqanaba ngalinye lamandla yimimandla yedayimani echithiwe emva kwempembelelo kwimpembelelo kwimpembelelo kwimpembelelo kwifuthe lezinyo ngalinye.

I-2. Uvavanyo olungenakumbi

Eyona ndlela isetyenziswa kakhulu yokuvavanya ubuchule bokuvavanya

Itekhnoloji ye-C scanng inokufumana iziphene ezincinci kwaye ichonge indawo kunye nobungakanani beziphene. Xa usenza olu vavanyo, indawo yokuqala ye-PDC izinyo kwitanki lamanzi, kwaye emva koko uskene nge-Ultrasonic Probe;
