ʻO ka mālama ʻana no ka hana ʻana i nā koʻokoʻo keleawe tungsten

ʻO ke koʻokoʻo keleawe tungstenhe pseudo-alloy ʻelua ʻāpana i haku ʻia me nā mea tungsten a me nā mea keleawe.He mea metala matrix composite mea.Ma hope o ka hui ʻana o nā mea i hoʻohui ʻia, ʻaʻohe hopena kemika, a mālama kēlā me kēia i nā ʻano kino kino a me nā ʻano mechanical.Hoʻomākaukau ʻia kēia mea e kahi kaʻina hana kūikawā o ka pauka metallurgy.Hoʻokumu ʻo Tungsten i kahi iwi i loko o ka huila, a komo ke keleawe i loko o ka āpau o ka iwi tungsten, kahi e hui pū ai i nā pono o ka helu hoʻoheheʻe kiʻekiʻe a me ke kūpaʻa wela o ka tungsten ponoʻī.Hoʻonui ka notch sensitivity i ka plasticity o ka alloy.

ʻOiaʻiʻo, i ka wā e hoʻoponopono ai i ke koʻokoʻo keleawe tungsten, pono e ʻike ʻia nā ʻano mālama kūpono.I ka hana ʻana i nā ʻāpana tungsten-keleawe e hana i nā kihi ʻoi a me nā paia lahilahi, hiki mai nā hemahema ma muli o ka hopena a i ʻole ka nui o ka hoʻouka ʻana i ka mīkini.Ke wili ʻia nā huahana tungsten-copper-silver-tungsten alloy ma nā lua, e ʻoluʻolu e hoʻolohe i ka hānai ʻana i ka wā e kokoke ana e wili ʻia nā lua.Hoʻouka ikaika, pale i nā hemahema machining, tungsten copper alloy he non-magnetic, e ʻoluʻolu e hōʻoia i ka paʻa paʻa o ka huahana ma mua o ka hana.
Eia kekahi, ʻo ka hoʻokuʻu ʻana a me ka wikiwiki o ka ʻoki ʻana i ka uila o ka mīkini hoʻokuʻu uila a me ka ʻoki ʻana i nā kaula keleawe tungsten he lohi, he mea maʻamau.No nā alloys i haku ʻia me ka tungsten a me ke keleawe, ʻo ka ʻike keleawe o nā alloys maʻamau ʻo 10% -50%, a ua hana ʻia nā alloys e ka pauka metallurgy method.He maikaʻi ka uila conductivity, thermal conductivity, maikaʻi kiʻekiʻe wela ikaika a me kekahi plasticity.Ma nā mahana kiʻekiʻe loa, e like me ma luna o 3000 degere Celsius, ua hoʻoheheʻe ʻia ke keleawe i loko o ka alloy a hoʻoheheʻe ʻia, e komo i ka nui o ka wela a hoʻemi i ka mahana o ka ʻili o ka mea.No laila, kapa ʻia kēia ʻano mea i ka mea hoʻoheheʻe metala.
