PDC Bit Cutter Gukora

PDC bits ikata yitwa Polycrystalline Diamond Compact Cutter.Ibikoresho byubukorikori ni 90-95% bya diyama isukuye kandi bikozwe mubice byashyizwe mumubiri wa biti. Ubushyuhe bwo hejuru bwo guterana hamwe nubwoko bwa bits bwatumye diyama ya polycristaline ivunika kandi ibyo byatumye habaho iterambere rya Thermally Stable Polycrystalline Diamond - TSP Diamond.

PCD (Polycrystalline Diamond) ikorwa mubyiciro bibiri byubushyuhe bwo hejuru, inzira yumuvuduko mwinshi. Icyiciro cya mbere muriki gikorwa ni ugukora kristu ya diyama yubukorikori mugushushanya grafite, imbere ya Cobalt, nikel, hamwe nicyuma cyangwa manganese catalizator / igisubizo, kumuvuduko uri hejuru ya 600.000 psi. Muri ibi bihe, kristu ya diyama ikora vuba. Nyamara, mugihe cyo guhindura igishushanyo cya diyama, habaho kugabanuka kwijwi, bigatuma catalizator / solvent itembera hagati ya kristu ikora, ikabuza guhuza intercrystalline bityo rero hakozwe ifu ya kirisiti ya diyama gusa muri iki gice cyibikorwa.

Mu cyiciro cya kabiri cyibikorwa, PCD yambaye ubusa cyangwa 'gukata' ikorwa nigikorwa cyo gucumura icyiciro. Ifu ya diyama yakozwe mugice cya mbere cyibikorwa ivangwa neza na catalizator / binder kandi ihura nubushyuhe burenga 1400 ℃ hamwe nigitutu cya 750.000 psi. Uburyo bwibanze bwo gucumura ni ugushonga kristu ya diyama kumpande zayo, mu mfuruka, no ku muvuduko mwinshi uterwa n’ingingo cyangwa impande zombi. Ibi bikurikirwa no gukura kwa epitaxial ya diyama kumaso no kumwanya wibice bito byo guhuza hagati ya kristu. Ubu buryo bwo kongera imbaraga bugizwe na diyama nyayo-diyama usibye guhuza amazi ava muri zone ya bond. Binder ikora urusobe rwinshi cyangwa ruto rukomeza rwa pore, rubaho hamwe numuyoboro uhoraho wa diyama. Ubusanzwe diyama yibanze muri PCD ni 90-97 vol.%.

Niba umuntu akeneye guhuzagurika aho PCD ihujwe na chimique na tungsten karbide substrate, bimwe cyangwa byose bihuza PCD birashobora kuboneka mumashanyarazi ya tungsten ya karubide yegeranye no gushonga no gukuramo cobalt ya karbide ya tungsten.

Niba ushishikajwe no gukata PDC ukaba ushaka ibisobanuro byinshi nibisobanuro birambuye, urashobora kutwandikira ukoresheje terefone cyangwa ubutumwa ibumoso, cyangwa UKOHEREZA MAIL US hepfo yurupapuro.
