Mukutsvagisa nekugadzirwa kwezvinhu zvinogadzirwa necemented carbide, tinowanzotora "kuchengetedza zvimwe zvinhu zvecemented carbide nekuvandudza kusimba kwayo nepose patinogona napo" sechinangwa chetsvakiridzo, kuti tiwane kushanda kuri nani.

Kufanana nemidziyo yesimbi, kuoma kwecemented carbide kunogona kuratidzwa maererano nekuoma kwesimba uye kuomarara kwekutsemuka. Pane hukama hwemutsara pakati pekusimba kwekukanganisa uye kuchinjika kwesimba resimende carbide. Izvo zvinhu zvinosarudza kusimba kweiyo alloy zvinokanganisa zvakanyanya kuoma kweiyo alloy. Iko kukanganisa kuoma kweiyo alloy kunokanganisawo nezvimwe zvinhu.

Impact kuomarara ndiko kugona kwechinhu kuramba kutadza pasi pekurodha. Kukanganisa kwemukati mune alloys kune zvakafanana mhedzisiro pane flexural simba uye kukanganisa kuoma. Kazhinji, ma alloys akaomarara zvinhu zvinoputika, uye iyo elastic deformation yebasa inoverengera chikamu chikuru kana ichinge yabatwa, saka kuchinjika kwesimba reiyo alloy kune yakakosha pesvedzero pakukanganisa kusimba kukosha.

Kune iyo alloy ine 10% Co, nekuwedzera kweWC saizi yezviyo, kunyangwe kuomarara kweiyo alloy kunowedzera, simba rekuchinja rinodzikira uye kukosha kwekusimba kunoderera zvakare, zvichiratidza kuti simba rekunyunguduka rinoita basa rinotungamira mukuoma kwesimba. .

Sezvo kuoma kwecemented carbide kunowedzera, kuoma kwekupwanya kunowedzera kuderera. Asi mukati mehumwe huwandu, zvinoratidza kuti zvimwe zvinhu zvinokanganisawo kuomarara kwekutsemuka pasi pekuoma kwakafanana.

Nekuongorora hukama pakati pekuomarara kwekukanganisa, kuomarara kwekutsemuka uye zvimwe zvemichina zvimiro uye zvimiro zvesimende carbide inogadzirwa neakasiyana maumbirwo, WC particle size uye akasiyana maitirwo ezvinhu, tinotora zvinotevera mhedziso:

Pane zvinhu zvakawanda zvinokanganisa kusimba kwekukosha kwecemented carbide, kunyanya kusanganisira kukanganisa kwechimiro, simba uye kusimba, nezvimwewo. Kukanganisa kwemaitiro emagetsi kunoderedza kusimba kwekushanduka uye kusimba kwemaitiro panguva imwe chete. The flexural simba of the alloy ine simba guru pakusimba kwekukanganisa.The effect toughness uye flexural simba inochengetedza humwe hukama hwemutsara. Chete pasi pemamiriro eiyo yakafanana flexural simba, alloys ane yakanaka kutyoka kuomarara anoratidza zvirinani kukanganisa kuoma.

Kutyoka kwekuomarara kwecemented carbide kunonyanya kuenderana nekuoma. Sezvo kuoma kweiyo alloy kunowedzera, kuomarara kwekutsemuka kunodzikira zvine mutsetse, asi kunochinja mukati meimwe nhanho. Kana kuomarara kwakafanana, iyo yakaderera-Co coarse-grained alloy ine nani kutyoka kuoma. Homogeneously yakarongwa alloys ane yakakwirira kuputsika kusimba asi yakaderera flexural simba uye kukanganisa kuoma pane asina-homogeneously akarongwa alloys.

Kuenzaniswa nekusimba kwekusimba kukosha kwecemented carbide, iyo yekuputsika kuoma kukosha kune kwakakosha kunoshanda kukosha. Yakasanganiswa neatatu emagetsi ekuita zviratidzo zvekuputsika kuoma, kuoma uye kuchinjika simba reiyo alloy, Inogona kuratidza zvirinani kuita kweiyo alloy.
