Abstract
Shamba: Metallurgy.
Chinhu: Chiangwa chinorondedzera kune poda metallurgy munda. Kunyanya inoenderana nekugamuchira kwekutadza kuomesa maitiro akaomarara pahwaro hwe tungsten carbide. Inogona kushandiswa kuti iite cutters, inodhonzera uye kugaya cutter. Alloy Alloy ine 80.0-82.0 wt% tungsten carbide uye 18.0-20.0 wt% yekubatanidza. Kusungira kune, WT%: Molybdenum 48.0-50.0; Niobium 1.0-2.0; Rhenium 10.0-12.0; Cobalt 36.00-4.0.
Mhedzisiro: Kugashira kune yakakwirira-simba acloy.
Tsanangudzo
Chigadzirwa chinorondedzera kumunda weupfu mitallururgy uye yekugadzirwa kwekutadza zvakaoma zvakavakirwa pane tungsten chombo, chinogona kushandiswa kuti chigadzire chevakachinjika, madhiri, zvidhori uye zvimwe zvishandiso.
Inozivikanwa yakazivikanwa carbide yakavakirwa pamakona emabhonzo, ane 3.0 kusvika ku20.0 wt.% Binder alloy ine, wt.%: Cobalt 20.00-75.0; Molybdenum - anosvika 5.0; Niobium - kusvika 3.0 [1].
Chinangwa chekugadzira ndechekuwedzera simba reiyo alloy.
Mhedzisiro yehunyanzvi inowanikwa mune iyo mune yakaomeswa akaomarara zvakavakirwa pane tungsten carbide ine 80.0-82.0 - Binder ine, WT.%: Molybdenum 48 0-50.0; Niobium 1.0-2.0, Rhenium 10.0-12.0; Cobalt 36.00-4.0.
Patafura. 1 Inoratidza kuumbwa kweiyo alloy, pamwe nesimba rekupedzisira mukukotama. Patafura. 2 Inoratidza kuumbwa kweLigament.
Tafura 1 Zvikamu Zvikamu, WT.%: Imwe 2 3 Wolfram carbide 80.0 81.0 80.0
Tafura 2
Iyo polloders yezvinhu zvakanyorwa zvakanyorwa mune yakaratidzwa chikamu, musanganiswa unodzvanywa pasi pekumanikidzwa kwe4,5--4.8 uye cm 2 uye anotenderwa mumoto wemagetsi ° C mune vacuum kwemaawa 7-9. Panguva yekuchinjisa, iyo binder inodonha chikamu che tungsten carbide uye melts. Mhedzisiro yacho ndeyechiratidzo chakasviba chine chimiro chine tungsten carbide zvimedu zvakabatana neBinder.
