Ingaruka zo kuvura hejuru ya diyama

1. Igitekerezo cyo gutwikira hejuru ya diyama

Ubuso bwa diyama, bivuga ikoreshwa rya tekinoroji yo gutunganya hejuru ya diyama yubatswe hamwe nibindi bikoresho bya firime. Nkibikoresho byo gutwikira, mubisanzwe ibyuma (harimo na alloy), nkumuringa, nikel, titanium, molybdenum, umuringa tin titanium alloy, nikel cobalt alloy, nikel cobalt fosifore, nibindi.; ibikoresho byo gutwikira kandi ibikoresho bimwe na bimwe bitari ubutare, nka ceramics, karbide ya titanium, titanium ammonia nibindi bikoresho bivanga ibikoresho bikomeye. Iyo ibikoresho byo gutwikira ari ibyuma, birashobora kandi kwitwa metero ya diyama.

Intego yo gutwikira hejuru ni uguha diyama ibice byihariye bya fiziki na chimique, kugirango tunonosore imikoreshereze yabyo. Kurugero, ikoreshwa rya diyama yometse hejuru yububiko bwa resin gusya, ubuzima bwumurimo buragurwa cyane.

2. Gutondekanya uburyo bwo gutwikira hejuru

Uburyo bwo gutunganya inganda zashyizwe mubikorwa reba igishushanyo gikurikira, cyashyizwe mubikorwa muburyo bukomeye bwo gutwikira hejuru yubutaka, abantu benshi bazwi cyane cyane ni ugushiraho imiti itose (nta plaque ya electrolysis) hamwe no gufata amasahani, isahani yumye (bizwi kandi ko bita vacuum plaque) mububiko bwa chimique chimique (CVD) hamwe nububiko bwa pompe metallurgique, hakoreshejwe uburyo bwo gukoresha amazi ya vacuum.

 

3. Gushyira umubyimba byerekana uburyo

Kuberako umubyimba wubuso bwubuso bwa diyama abrasive ibice bigoye kubimenya neza, mubisanzwe bigaragazwa nkiyongera ibiro (%). Hariho uburyo bubiri bwo kongera ibiro:

Aho A ni kwiyongera ibiro (%); G1 nuburemere bwo gusya mbere yo gufata; G2 ni uburemere bwo gutwikira; G nuburemere bwuzuye (G = G1 + G2)

4. Ingaruka yubuso bwa diyama kumikorere yibikoresho bya diyama

Mu gikoresho cya diyama cyakozwe na Fe, Cu, Co na Ni, uduce twa diyama dushobora kwinjizwa mu buryo bwa mashini gusa muri materix ya agent kubera ko nta miti iva mu miti yavuzwe haruguru no kubura kwinjira. Mubikorwa byo gusya imbaraga, mugihe igice cyo gusya diyama gihuye nigice kinini, icyuma cyumubiri wapine kizatakaza uduce twa diyama kandi kigwe ubwacyo, ibyo bikaba bigabanya ubuzima bwa serivisi no gutunganya neza ibikoresho bya diyama, kandi ingaruka zo gusya za diyama ntizishobora gukinwa neza. Kubwibyo, ubuso bwa diyama bufite imiterere ya metallisation, bushobora kuzamura neza ubuzima bwa serivisi no gutunganya neza ibikoresho bya diyama. Intego yacyo ni ugukora ibintu bihuza nka Ti cyangwa ibivanze byayo bitwikiriye neza hejuru ya diyama, binyuze mu gushyushya no gushyushya, ku buryo ubuso bwa diyama bugira urwego rumwe rukomatanya imiti.
Mugusiga diyama gusya ibice, reaction ya coating na diyama kugirango ube hejuru ya diyama. Ku rundi ruhande, hejuru ya diyama yubatswe hamwe nicyuma gihuza umubiri hagati yicyuma cya metallurgiki, bityo rero, kuvura diyama kugirango umuvuduko ukonje wogukonjesha hamwe no gushyushya icyiciro cya fonction fonctionnement bifite akamaro kanini, kubwibyo umubiri wapine umubiri wa diyama yo gusya ingano wiyongereye, kugabanya igikoresho cya diyama mugukoresha urusyo, kugirango ubuzima bwa serivisi bukorwe neza.

5. Ni ibihe bikorwa by'ingenzi byo kuvura diyama?

1. Kunoza ubushobozi bwimikorere yumubiri wigitereko cyo gushiramo diyama.
Bitewe no kwaguka k'ubushyuhe no kugabanuka gukonje, guhangayikishwa cyane nubushyuhe bikorerwa ahantu hahurira hagati ya diyama numubiri wapine, bizatuma diyama numukandara wo guhuza umubiri utanga imirongo ntoya, bityo bikagabanya ubushobozi bwumubiri wapine wasizwe na diyama. Ubuso bwa diyama bushobora kuzamura imiterere yumubiri nubumara bwa diyama nu mubiri, binyuze mu isesengura ry’ingufu zerekana ingufu, yemeje ko icyuma cya karbide cyuma muri firime kuva imbere kugeza hanze kigenda gihinduka buhoro buhoro mubintu byuma, bita firime ya MeC-Me, ubuso bwa diyama na firime ni isano ya shimi, gusa uku guhuza gushobora kuzamura ubushobozi bwa diyama, cyangwa kuzamura ubushobozi bwumubiri wa diyama. Nukuvuga, gutwikira bikora nkikiraro gihuza byombi.
2. Kongera imbaraga za diyama.
Kuberako kristu ya diyama ikunze kugira inenge imbere, nka microcrack, cavites ntoya, nibindi, izo nenge zimbere muri kristu zishyurwa no kuzuza membrane ya MeC-Me. Isahani igira uruhare rwo gushimangira no gukomera. Isahani yimiti hamwe nisahani irashobora kunoza imbaraga zibicuruzwa bito, bito n'ibiciriritse.
3. Gabanya umuvuduko ukabije.
Icyuma gitwikiriye gahoro kuruta icya diyama. Ubushyuhe bwo gusya bwanyujijwe kuri resin ihuza ibintu bihuye nu gusya, ku buryo bitwikwa biturutse ku bushyuhe bw’ubushyuhe bukabije ako kanya, kugira ngo bigumane imbaraga zifata diyama.
4. Kwigunga n'ingaruka zo gukingira.
Mugihe cy'ubushyuhe bwo hejuru no gusya ku bushyuhe bwo hejuru, igipfundikizo gitandukanya kandi kirinda diyama kugirango wirinde gushushanya, okiside cyangwa izindi mpinduka z’imiti.
Iyi ngingo yakomotse kuri "umuyoboro wibikoresho bya superhard"
