Isitsha sikaphethiloli wesikebhe se-Molybdenum sintered ukumelana nezinga lokushisa eliphezulu
Njengamanje, abakhiqizi bezikebhe ze-molybdenum basekhaya abasetshenziselwa ukudweba izintambo ezinhle kakhulu basebenzisa imichilo encibilikayo eqondile kanye nemicu ye-sintered.
Ngemva kweminyaka eminingana yokuzijwayeza ukukhiqiza amabha e-molybdenum, sikholelwa ukuthi okugxilwe kakhulu kumakristalu emigqa i-β Ammonium molybdate inomphumela ongcono njengento yokuqhubekisela phambili ukucutshungulwa kwemicu yokuncibilika eqondile ekhiqizwa ukuncishiswa nokucindezela kusetshenziswa ubuchwepheshe bokugazinga. Njengamanje, abakhiqizi be-molybdenum strip e-China bavame ukusebenzisa le nto njengento yokudweba imichilo yocingo ye-molybdenum. Ngaphezu kokulandela umkhondo wekristalu, okuqukethwe kwezakhi eziyinhloko njenge-potassium ne-sodium, izakhiwo ezibonakalayo ezifana ne-porosity nosayizi wezinhlayiyana zidinga ukuhlangabezana nezidingo ezithile futhi kugcinwe ukuzinza okuhlobene.
Ukunakekelwa okukhethekile kufanele kuthathwe ngesikhathi sokushisa okuphansi kwe-sintering yama-billet acindezelwe. Ngenxa ye-brittleness ye-molybdenum, ama-billet awakwazi ukupholisa noma ukushiswa ngokuzumayo. Kungakhathalekile ukuthi i-sintering noma ukupholisa, kufanele kube nendawo yebhafa yezinga lokushisa ukuvikela ukuphuka. Isikhathi nokushisa kwe-sintering yezinga lokushisa eliphansi kufanele kulawulwe kahle, ukuze amabhilidi angakwazi nje ukususa ukungcola okuphansi, kodwa futhi athuthukise amandla kanye ne-conductivity, okuhambisana nokucubungula ukuncibilika okuqondile.
Isetshenziswa kakhulu kubuchwepheshe bokunamathela, imboni ye-elekthronikhi, ubunjiniyela bamandla, njengokuhwamuka kwe-vacuum thermal (isikebhe sokuhwamuka kwesinyathela), i-capacitor sintering, i-nuclear combustion sintering, amagobolondo e-thermocouple, njll. Empeleni ingumkhumbi okwazi ukumelana nezinga lokushisa eliphezulu ongasetshenziswa ku-vacuum izithando zomlilo nezingilazi zokuncibilikisa. Uma kuqhathaniswa ne-molybdenum crucibles, enesakhiwo esilula nezindleko eziphansi, izikebhe ze-molybdenum zivame ukusetshenziswa ezimbonini zokushisa ukushisa okuphezulu, njengeziko le-vacuum, i-ammonia furnaces, iziko lezimboni, nezinye iziko lokushisa eliphezulu njengeziqukathi zezinto ezibonakalayo.
