Hard alloy ke lisebelisoa tsa alloy tse entsoeng ka metsoako e thata ea litšepe tse refractory le litšepe tse kopantsoeng ka mokhoa oa metallurgy oa phofo, o nang le boima bo phahameng, ho hanyetsa ho roala, matla a matle le ho tiea. Ka lebaka la ts'ebetso ea eona e ikhethang, hangata e sebelisoa ho etsa lisebelisoa tsa ho phunya majoe, lisebelisoa tsa merafo, lisebelisoa tsa ho phunya, lisebelisoa tsa ho lekanya, joalo-joalo. E sebelisoa haholo libakeng tse kang oli le khase, indasteri ea lik'hemik'hale, mechine ea boenjiniere le taolo ea metsi. Hard alloy ke thepa e entsoeng ka ho hatella ka mokhoa oa metallurgy oa phofo.

1. E hlophisitsoe

Boholo ba layering bo qala ho tloha mathōkong ebe bo fetela ho billet. Lebaka la ho beoa ha sekhahla sa compression ke khatello ea maikutlo e ka hare kapa tsitsipano ea elastic ho block block. Ka mohlala, motsoako oa cobalt oa motsoako o batla o le tlaase, boima ba carbide bo phahame, phofo kapa likaroloana li ntle haholo, motsoako oa ho etsa o fokola haholo kapa o arotsoe ka mokhoa o sa tšoaneng, motsoako o kolobile haholo kapa o omme haholo, khatello ea khatello e matla haholo. e kholo, boima bo le bong bo boholo haholo, sebopeho sa sekontiri se rarahane, boreleli ba hlobo bo futsanehile haholo, 'me sebaka sa tafole ha se lekane, kaofela ha sona se ka baka layering.

2. Mapetso

Ketsahalo ea ho robeha ho sa tloaelehang ha sebaka ka har'a boloko e hatelitsoeng e bitsoa cracking. Ka lebaka la khatello ea maikutlo ka hare ho thibelo ea khatello e kholo ho feta matla a thata a thibelo ea thibelo. Khatello ea khatello e ka hare ho "compress" block e tsoa ho khatello ea kelello e ka hare. Lintho tse amang delamination li boetse li ama mapetsong. Mehato e latelang e ka nkuoa ho fokotsa ho hlaha ha mapetsong: ho lelefatsa nako ea ho ts'oara kapa ho hatella makhetlo a mangata, ho fokotsa khatello, boima bo le bong, ho ntlafatsa moralo oa hlobo le ho eketsa botenya ba hlobo ka nepo, ho potlakisa lebelo la ho theola, ho eketsa li-agents, le ho eketsa bongata ba lintho tse hlephileng.
