Isesengura Ibiranga Isesengura ryibikoresho bitanu bya superhard Gukata ibikoresho

Ibikoresho bya superhard bivuga ibikoresho bya superhard bishobora gukoreshwa nkigikoresho cyo gutema. Kugeza ubu, irashobora kugabanywamo ibyiciro bibiri: ibikoresho byo gukata diyama hamwe nibikoresho bya cubic boron nitride. Hariho ubwoko butanu bwingenzi bwibikoresho bishya byakoreshejwe cyangwa biri kugeragezwa

(1) Kamere isanzwe nubukorikori nini nini ya kirisiti ya diyama

.

(3) CVD diyama

(4) Polycrystal cubic boron ammonia; (PCBN)

(5) CVD cubic boron ammonia

1, karemano na sintetike nini imwe ya kirisiti ya diyama

Diyama isanzwe ni imiterere imwe ya kirisiti idafite imbibi zimbere, kugirango igikoresho cyibikoresho gishobora kugera muburyo bworoshye bwa atome no gukara, hamwe nubushobozi bukomeye bwo gutema, busobanutse neza nimbaraga nto zo gutema. Gukomera, kwambara birwanya no kwangirika hamwe no gutuza imiti ya diyama karemano itanga ubuzima burebure bwigikoresho, birashobora kugabanya igihe kirekire gisanzwe, kandi bikagabanya ingaruka zo kwambara ibikoresho kubice bitunganijwe neza, ubushyuhe bwacyo bwinshi burashobora kugabanya ubushyuhe bwo kugabanya no guhindura ubushyuhe bwibice. Ibintu byiza biranga diyama nini nini ya kirisiti irashobora kuba yujuje ibyangombwa bisabwa kugirango ugabanye ibikoresho. Nubwo igiciro cyacyo gihenze, iracyamenyekana nkibikoresho byiza bya ultra precision nibikoresho bya ultra precision, birashobora gukoreshwa cyane mugutunganya ibyuma bya kirimbuzi nubundi buhanga buhanitse mubijyanye nindorerwamo, misile na roketi, mudasobwa ya disiki ya disiki, imashini yihuta ya elegitoronike, hamwe n’ibice by’isaha gakondo, imitako, amakaramu, ibikoresho byo gutunganya ubwonko bwa tekinike, n'ibindi. ibikoresho by'ubuvuzi. Iterambere ryubu ryubushyuhe bwo hejuru hamwe nubuhanga bwumuvuduko mwinshi bituma bishoboka gutegura diyama nini nini ya kirisiti ifite ubunini runaka. Ibyiza byibi bikoresho bya diyama nubunini bwayo, imiterere n'imikorereIbyo bihoraho, bitagerwaho mubicuruzwa bya diyama bisanzwe. Bitewe n'ubuke buke bwa diyama nini itangwa, igiciro gihenze, igice kinini cya sintetike nini ya kristu ya diamant ibikoresho byo gutema ultr-precision gutunganya nkibisanzwe binini bya diyama isanzwe isimbuye, ikoreshwa ryayo rizatezwa imbere byihuse.

2, diyama ya polycristal (PCD) na polycristal diamant composite blade (PDC) ugereranije na diyama nini nini ya kirisiti nkigikoresho cyibikoresho bya diyama ya polycristal (PCD) na polycristal diamant compte blade (PDC) bifite ibyiza bikurikira: (1) gahunda idahwitse, isotropique, nta buso bwa clavage. Kubwibyo, ntabwo bimeze nka diyama nini imwe ya kirisiti ya diyama ku mbaraga zitandukanye za kirisiti, gukomera

Kandi kwihanganira kwambara biratandukanye cyane, kandi kuberako hariho ubuso bwa clavage kandi bworoshye.

. Ariko nanone irashobora gukoreshwa nkumubare munini wo gutunganya ibintu no gutunganya rimwe na rimwe (nko gusya, nibindi), byagura cyane ikoreshwa ryibikoresho bya diyama.

.

(4) Imiterere yihariye irashobora gukorwa kugirango ihuze ibikenewe gutunganywa bitandukanye. Bitewe no kunoza ibikoresho bya PDC hamwe na tekinoroji yo gutunganya nka spark yamashanyarazi, tekinoroji yo gukata laser, mpandeshatu, herringbone, gables nizindi fagitire zidasanzwe zishobora gutunganywa no gushingwa. Kugirango uhuze ibikenewe ibikoresho bidasanzwe byo gukata, birashobora kandi gushushanywa nkibipfunyitse, sandwich no kuzunguza bileti ya PDC.

(5) Imikorere yibicuruzwa irashobora gutegurwa cyangwa guhanurwa, kandi ibicuruzwa bihabwa ibimenyetso bikenewe kugirango bihuze nikoreshwa ryabyo. Kurugero, guhitamo neza ibikoresho bya PDC ibikoresho bishobora kuzamura ubwiza bwibikoresho; ibikoresho bya PDC byuzuye ibikoresho birashobora kunoza igihe cyigikoresho.

Mu gusoza, hamwe niterambere ryibikoresho bya PCD na PDC, ikoreshwa rya PCD na PDC ryaguwe byihuse mubikorwa byinshi

Inganda zikoreshwa cyane mubyuma bidafite fer (aluminium, aluminiyumu, umuringa, umuringa wumuringa, magnesium alloy, zinc alloy, nibindi), karbide, ceramique, ibikoresho bitari ibyuma (plastike, reberi ikomeye, inkoni ya karubone, ibiti, sima, nibindi), ibikoresho bikomatanya (nka fibre ishimangira plastike CFRP, ibyuma bya matrike bihinduranya cyane, gutunganya ibiti bya MMCs, gutunganya ibyuma bya MMCs karbide.
