Ese ni iki gikoresho cyo kwambaraho carbide kidapfa kwangirika kandi kuki kidapfa kwangirika kurusha icyuma gisanzwe?

Mu nganda zikomeye nko mu bucukuzi bw'amabuye y'agaciro, sima, no gutanga amashanyarazi, gusaza kw'ibikoresho ni ikibazo gikomeye. Ibikoresho bisanzwe by'icyuma bikunze kwangirika vuba, bigatuma bidakora neza kandi bigasanwa bihenze. Aha niho ibikoresho bikoreshwa cyane.Isahani yo kwambaraho karubide ya chromiumihinduka ikintu gishya. Ariko se ni iki gituma idasharira cyane kurusha icyuma gisanzwe?

Gusobanukirwa uburyo bwo kwambara icyuma gitwikiriye chromium carbide

Isahani yo kwambaraho karubide ya chromium ni ibikoresho byihariye byagenewe kurwanya kwangirika gukabije mu bidukikije. Igizwe n'icyuma gito cya karubide gitwikiriwe n'urwego rukomeye rukungahaye ku duce twa karubide ya chromium, cyane cyane Cr₇C₃. Izi karubide zigira uruhare rumwe mu gihe cyo gusudira kandi zikwirakwira ku buso bumwe, zigatanga uburinzi budasanzwe ku kwangirika, ingaruka, no gusukura.

Bitandukanye n'amasahani asanzwe y'icyuma, ashingiye gusa ku bukomere bw'icyuma cy'ibanze, aya masahani akoresha ibyiciro bikomeye by'aluminiyumu biri muri matrix, bigatuma igihe cyo gukora kirushaho kuba kinini.

Impamvu Irusha Ibyuma Bisanzwe Ikora Kurusha Ibyuma Bisanzwe

1. Imiterere ya Karubide nziza cyane

Ipfundo ryo kudashira ni ubwoko n'uburyo karubide zikwirakwira. Icyuma gisanzwe kirimo karubide zishingiye ku cyuma nka Fe₃C, zoroshye kandi zoroshye kwangirika. Mu buryo bunyuranye, ibyuma bya chromium carbide bishyiraho karubide nyinshi nka Cr₇C₃ - ibintu bigaragaza ubukana bwa HRC 58–65.

Izi karubide zifite ubushobozi bwo kudacika intege no kudacika intege, cyane cyane iyo hari umuyaga wumye cyangwa ubushyuhe bwinshi.

Igishimishije: Uko ikigereranyo cya atome cya chromium na karuboni kiri hejuru, ni ko karubide zirushaho gukomera kandi zihamye - ikintu cy'ingenzi mu gutuma icyuma gisanzwe kidashira gikora neza kurusha ikindi.

2. Imiterere mito igezweho

Mu masahani yo kwambara neza, inkingi ikomeye ifite matrix ya martensitic irimo karubide nyinshi zikwirakwijwe neza. Iyi miterere ivanze ituma isahani idacika intege ndetse n'ingufu ziciriritse, bigatuma irushaho gukoreshwa.

Ariko, iyo karubide zikozwe mu buryo butangana — nko mu nyubako zimeze nk'urushundura cyangwa ku nkengero z'ingano — ubushobozi bwo kwangirika bushobora kugabanuka cyane. Niyo mpamvu gutunganya no kugenzura ari ingenzi cyane.

3. Ingufu zikomeye zo gusudira no gukora

Bitandukanye n'ibimera byoroshye cyangwa ibyuma by'icyuma,amasahani yo kwambara avanzeifite urufatiro rworoheje rw'icyuma rutuma byoroshye gusudira, kunama no gukata - harimo no gukata plasma na laser. Ibi bituma abakora ibikoresho bakora imiterere igoye nk'imirongo igoramye, imirongo ishaje, n'ibice by'imiterere kugira ngo bishyirwemo ibintu byihariye.

Uburyo bwo gukoresha mu buzima busanzwe: Ni hehe aya masahani akoreshwa?

Isahani yo kwambara ya chromium carbide ikoreshwa cyane mu nzego aho kwambara cyane ari ibintu bikunze kubaho buri munsi:

Ubucukuzi bw'amabuye y'agaciro: Gutwara imizigo, imiyoboro,ibyapa byo kugaragaza

Ibikoresho bya sima: Ibice bitandukanya, ibikoresho byo kugaburira ibyuma, n'ibikoresho byo gutwara ibyuma

Inganda zitanga ingufu zishyuha: Imashini zitunganya amakara, uburyo bwo gufata ivu

Inganda zikora ibyuma: Inganda zikora sinter, udusanduku tw'ibikoresho,imiyoboro yo gusohora

Muri buri kibazo, gusimbuza ibice bisanzwe n'isahani ya chromium nyinshi byongera cyane igihe cyo kubaho kandi bigabanya isuku idateganyijwe.

Guhitamo isahani ikwiye yo kwambara

Mu gihe uhitamo icyuma gikoreshwa mu gupfuka icyuma gikoresha chromium carbide, tekereza kuri ibi bikurikira:

Ubugari n'imiterere y'aho ibintu bihurira (urugero: 4+4mm, 6+6mm, 8+6mm)

Igice cy'ingano ya karubide (30%+ ni cyo gikundwa)

Uburyo bwo gusudira (uruziga rwinjijwe mu mazi ugereranije n'uruziga rufunguye)

Ibisabwa mu gukata (plasma, laser)

Nanone, buri gihe genzura niba ibicuruzwa byujuje ibipimo by'ubuziranenge nko kuba imiterere y'ubukana, imiterere y'icyuma, no kudakora neza.
