Umthelela wokuqukethwe kwe-W kusigaba se-tungsten carbide crystal bonding emandleni aguquguqukayo we-alloy

Amandla okugoba ayinto ebaluleke kakhulu ebonakalayo ye-carbide enosimende.Ngama-alloys aphezulu-cobalt, amandla ayo akhula ngokunyuka kokuqukethwe kwe-W;kuyilapho ama-alloys e-cobalt ephansi, okuphambene kuyiqiniso.

Lokhu kungenxa yokuthi ngemuva kwesigaba se-cobaltingxube ye-high-cobalti-solid-solution iqiniswa ngu-W, ukumelana ne-plastic deformation ye-alloy kuyathuthukiswa, ngaleyo ndlela kwandise amandla;ngenkathi iingxubevange ye-cobalt ephansii-brittle ngokwemvelo, futhi ngemva kokuba isigaba se-cobalt siqinile-isixazululo esiqiniswe ngu-W, amandla ayancishiswa.Amandla engxubevange.

Ubudlelwano phakathi kokumelana nokugqoka kanye nokuqukethwe kwe-W kufanele kuchazwe ngokusebenza kwesigaba sokubopha.Ukuphakama kokuqukethwe kwe-W, i-cobalt eyengeziwe iqiniswa futhi iphakamisa ukumelana nokugqoka;i-alloy inenani elincane le-eta yesigaba esingavimbeli ukumelana nokugqoka ngesikhathi sokusetshenziswa.Kodwa-ke, uma inani lesigaba se-eta likhulu, ingxubevange iyaphuka futhi ijwayele ukuphuka noma ukuphuka, okubangela ukulimala kumathuluzi engxubevange.
