I. Thermal kupfeka uye cobalt kubviswa kwePDC
Mukumanikidzwa kwepamusoro kwekutadza kwePCC, cobalt zviito zvekutengesa kusanganisa zvakananga kwedadhi uye tungsten kucheka kwePDC kucheka kwePDC.
Madhaimani ekupisa kupesana ane mashoma. Pasi pekumanikidzwa kwemhepo, pamusoro pedhaimani inogona kushandura pakupisa kwakakomberedza 900 × kana kupfuura. Panguva yekushandisa, tsika dzePDCS dzinowanzo kusvibisa panenge munenge muna 750 ℃. Kana achinge achinge achinge achirovera
Kuenzaniswa nedhaimani yakachena, nekuda kwekuvapo kweCobalt, madhaimani anotendeuka kugirafiringa padziya dzakadzika. Nekuda kweizvozvo, kupfeka pane Diamondi kunokonzerwa neiyo graphifisization inokonzerwa kubva kune yakakwenenzverwa kupisa kupisa. Pamusoro pezvo, kuwedzera kwekuwedzera kuwanda kwebaroti kwakanyanya kupfuura kwedare redhaimani, saka panguva yekupisa, kusungwa pakati pezviyo zvedhaimani kunogona kuvhiringidzwa nekuwedzera kwezororo.
Muna 1983, vaongorori vaviri vakaita madhaimani kubvisa kurapwa pamusoro peyakajairwa PDC Daimondi zviyero, nekuwedzera kuita kwePDC meno ePDC. Nekudaro, ichi chigadzirwa hachina kugashira kutariswa kwaifanirwa. Izvo hazvina kusvika zva2000 izvo, nekunzwisisa kwakadzama kwePDC madhaimani mateya, Drill Suppliers vakatanga kushandisa iyi tekinoroji kumeno ePDC anoshandiswa mukudhirowa. Mazino anobatwa nenzira iyi akakodzera magadzirirwo akanyanya kujairika ane akakosha anodzora mechaniki akapfeka uye anowanzo rondedzwa se "meno e-cobalted".
Iyo inonzi "de-cobalt" inogadzirwa nenzira yechinyakare yekugadzira PDC, uyezve pamusoro peyakagadzika yedanho. Uku kudzika kwekubvisa kwezana kunogona kusvika mazana maviri emadhora.
Iyo inorema-basa kupfeka bvunzo yakaitwa pameno maviri akafanana ePDC (imwe yeiyo yaive neyakagadziriswa cobalt yekubvisa paDiamondi layer pamusoro). Mushure mekucheka 5000m of granite, zvakawanikwa kuti iyo yekupfeka yeiyo isina-cobalt-yakabviswa PDC yakatanga kuwedzera zvakanyanya. Mukupesana, iyo cobalt-yakabviswa Pdc yakachengeta chinomhanyisa kutakura kumhanyisa kana kucheka kanenge 15000m yedombo.
2. Kuona nzira yePDC
Kune marudzi maviri enzira kuti uone mazino ePDC, iyo inoparadza inoedza uye isiri-inoparadza kuyedzwa.
1. Kuedza Kuedza
Iyi miedzo inoitirwa kutevedzera mamiriro ekunze sezvazvinogona kuongorora mashandiro ekucheka mazino mumamiriro ezvinhu akadaro. Maonero maviri makuru ekuparadza anoparadza anopfeka zvinopesana bvunzo uye zvinokanganisa miedzo yekudzivirira.
(1) Pfeka bvunzo dzekupesana
Mhando nhatu dzemidziyo dzinoshandiswa kuita PDCP kupfeka zvinodzivisa bvunzo:
A. Vertical Lahe (vtl)
Munguva yebvunzo, kutanga gadzirisa iyo PDC zvishoma kune vtl lihe uye isa dombo remuenzaniso (kazhinji granite) padyo nePDC zvishoma. Wobva watenderera dombo remumhanzi uchitenderedza iyo axis pane imwe yekumhanya. Iyo PDC zvishoma inocheka mudombo redombo neyakadzika yakadzika. Paunenge uchishandisa Granite yekuedza, ichi kudzika kwakadzika kuri kushoma pane 1 mm. Iyi bvunzo inogona kuve yakaoma kana yakanyorova. Mu "Dry Vtl kuongororwa," apo iyo PDC zvishoma ichipfuura padombo, hapana inotonhorera inoshandiswa; Kupisa kwese kwekupfeka kunopinda zvinopinda muPCC, kukurudzira maitiro emafirita edhaimani. Iyi yekuyedza nzira inopa mibairo yakanaka kwazvo kana ichinyatsoongorora PDC mabiti pasi pemamiriro ezvinhu anoda yakanyanya kuyerera kumanikidzwa kana yakanyanya kutenderera kumhanya.
Iyo "Wet Vtl bvunzo" inoona hupenyu hwePDC pasi pemamiriro ezvinhu ekupisa mwero nekutonhorera mazino ePDC nemvura kana mhepo panguva yekuyedza. Naizvozvo, iyo huru kupfeka sosi yebvunzo iyi ndeyekukuya kwedombo rekunyepedzera pane chinhu chekudziya.
B, yakatwasuka lathe
Iyi bvunzo inoitwawo neGranite, uye nheyo yemuedzo ndeye yakafanana neVTL. Iyo nguva yekuyedzwa ingori maminetsi mashoma, uye iyo inovhundutsa iri pakati peGrance nePDC meno ane mashoma.
Iyo granite bvunzo paramita inoshandiswa nePDC GEAR Suppliers ichasiyana. Semuenzaniso, ma parameter akaongororwa akashandiswa neCustomer Corporation uye Di kambani muUnited States haina kunyatsoitika, asi vanoshandisa iyo manyorerwo egiredhi giredhi polycrystalline igneous poros ine madiki e19mpa.
C. Abrasion Ratio kuyera chiridzwa
Mumamiriro ezvinhu akafungidzirwa, dhaimendi rePCC inoshandiswa kuTrim Silicon Cardide Glinding Wheel, uye iyo chiyero chekupfeka chekunyepa chePCC inotorwa seyekupfeka yePDC, iyo inonzi PERCE RATIO.
(2) Goverana kudzivisa bvunzo
Nzira yekukanganisa kuyedza inosanganisira kuisa mazino ePDC pakona ye15-25 degrees uye wozodonhedza chinhu kubva kune imwe kureba kurova madhaimani pameno ePDC yakatwasuka. Iyo uremu uye kukwirira kwechinhu chinodonha inoratidza iyo yakanganisa simba resimba rine ruzivo neinoyera zino, izvo zvinogona zvishoma nezvishoma kuwedzera kusvika pagumi. Zino rega rega rinogona kukanganiswa ka3-7 nguva kudzamara isingakwanise kuedzazve. Kazhinji, anosvika gumi samples emhando imwe neimwe yezino dzinoedzwa pane imwe neimwe simba. Sezvo paine huwandu hwekudzikisira kwemeno kuti ubatane, iwo muedzo unowana pane imwe neimwe esimba mwero wepakati edhaimondi inoshungurudza mushure mezino rimwe nerimwe.
2. Kuparadza kusingafadzi
Iyo inonyanya kushandiswa kushandiswa kusingafadzi nzira yekuyedza (kunze kwekunyepedzera uye microscopic yekuongorora) ndeyekupedzisira kuongorora (CSCAN).
C tekinoroji tekinoroji inogona kuona dema diki uye sarudza nzvimbo yacho uye saizi yehurema. Paunenge uchiita bvunzo iyi, tanga kuisa zino rePCC mune tangi yemvura, wobva waongorora nelarrasonic probe;
Chinyorwa ichi chakadhindwa kubva ku "International Metalworking Network"
