Carbide a me ka cermet hoʻomākaukau

Loaʻa i nā wili paʻa WC-Co ka hiki ke hoʻololi i ka microwave.I ka wā o ke kaʻina hana sintering, ʻo nā ʻano pohō e hana ana i ka ʻāpana wela haʻahaʻa, ʻo ia ka polarization hoʻomaha hoʻomaha a me ka nalowale magnetic, ʻoiai ma ka ʻāpana wela kiʻekiʻe e hoʻomoʻa ka alloy i ka ikehu microwave.Nui ma ke ʻano o ka nalowale dielectric a me ka nalowale conductivity.

ʻO kahuikaume ka hoʻohui o 0.4% VC a me 0.2% Cr3C2 (mass fraction) ma ke ʻano o nā mea kōkua i ka hana maikaʻi loa;ʻo ka hoʻohana ʻana i ka sintering microwave vacuum e hoʻomaikaʻi nui i ka hana o ka alloy.Ke hoʻohana nei i ka sintering microwave multi-cavityWC-8Co, ua sintered ma 1400 ° C me ka mālama ʻole ʻana i ka wela.Hiki i ka density ke hiki i 14.71g / cm, kaHiki i ka HRA90.3, a ua like ka hale.

Hiki ke hoʻohana ʻia ka ʻenehana sintering microwave no ka hoʻomākaukau ʻana i nā cermets ultra-fine me nā kīʻaha maikaʻi, ke ʻano like ʻole a me ka hana maikaʻi loa.Ke piʻi aʻe ka mahana o ka sintering, hoʻonui mua ka shrinkage, density, flexural ikaika a me ka paʻakikī o nā cermet ultra-fine a emi iho, me ka helu kiʻekiʻe loa ma 1500 ° C;ʻO ke kaʻina hana hoʻoheheʻe microwave kūpono no nā cermets ultra-fine Ma hope o ka mālama ʻia ʻana ma 1500°C no 30 mau minuke, ʻo ka ikaika flexural a me ka paʻakikī ko 1547MPa a me 90.6HRA pākahi, i hoʻonui ʻia e 24.0% a me 0.7% i hoʻohālikelike ʻia me ka sintering maʻamau.
