Ibintu Byombi Byibanze Byibikoresho bya PDC

Gukata PDC ni ubwoko bwibintu bikomeye cyane bigereranya diyama ya polycrystalline hamwe na karubide ya tungsten yubushyuhe bukabije nubushyuhe.

PDC Cutter yahimbwe bwa mbere na General Electric (GE) mu 1971. Cutters ya mbere ya PDC mu nganda za peteroli na gaze yakozwe mu 1973 kandi nyuma yimyaka 3 yo kugerageza no gupima umurima, byagaragaye ko ikora neza kuruta guhonyora karbide buto bits kugirango bamenyekanishe mubucuruzi muri 1976.

PDC Cutters ikozwe muri tungsten karbide substrate hamwe na diyama ya gritike. Diyama na karbide substrate ikurira hamwe ikoresheje imiti ihuza ubushyuhe bwinshi nubushyuhe bukabije.

Ibikoresho byingenzi byo gukata PDC ni diyama grit na karbide substrate.

1. Diamond grit

Diamond grit nigikoresho cyingenzi kubikoresho bya PDC. Ku bijyanye n’imiti n’imiterere, diyama yakozwe n'abantu isa na diyama isanzwe. Gukora diyama grit ikubiyemo uburyo bworoshye bwa chimique: karubone isanzwe ishyuha munsi yumuvuduko mwinshi nubushyuhe. Mu myitozo ariko, gukora diyama ntabwo byoroshye.

Diamond grit ntabwo ihagaze neza mubushyuhe bwo hejuru kuruta diyama isanzwe, nyamara. Kuberako ibyuma bya catalizike byafashwe muburyo bwa grit bifite umuvuduko mwinshi wo kwaguka kwinshi kurenza diyama, kwaguka gutandukanye gushira diyama-diyama munsi yimyenda kandi, niba imizigo ari myinshi bihagije, itera kunanirwa kwinguzanyo. Niba inkwano zananiranye, diyama iratakara vuba, PDC rero itakaza ubukana bwayo nuburakari bikagenda neza. Kugirango wirinde kunanirwa, gukata PDC bigomba gukonjeshwa bihagije mugihe cyo gucukura.

2. Carbide substrate

Carbide substrate ikozwe muri tungsten karbide. Carbide ya Tungsten (formulaire ya chimique: WC) nikintu cyimiti irimo tungsten na atome ya karubone. Ubwoko bwibanze bwa tungsten karbide ni ifu yumukara mwiza, ariko irashobora gukanda hanyuma igahinduka muburyo bwo gukanda no gucumura.

Carbide ya Tungsten ikoreshwa cyane mu bucukuzi bw'amabuye yo hejuru ya nyundo, inyundo zo hasi, imashini zogosha, imashini ndende ndende, gutoragura imashini ndende, kuzamura reamers irambiranye, hamwe n'imashini zirambirana.

Zzbetter ifite igenzura rikomeye kubikoresho bya diyama grit na karbide substrate. Mugukora peteroli ya PDC gucukura, dukoresha diyama yatumijwe hanze. Tugomba kandi kumenagura no kongera kubishiraho, bigatuma ingano yingingo imwe. Tugomba kandi kweza ibikoresho bya diyama. Dukoresha Laser Particle Ingano Yisesengura kugirango dusesengure ingano yikwirakwizwa ryayo, ubuziranenge, nubunini kuri buri cyiciro cyifu ya diyama. Dukoresha ifu yisugi yujuje ubuziranenge hamwe n amanota akwiye kugirango tubyare tungsten karbide substrates.

Kuri Zzbetter, turashobora gutanga intera nini yo gukata.
