Carbide extruded keleawe

1) ʻOi aku ka paʻakikī a me ka ʻaʻahu kūʻē I ka lumi wela, ka paʻakikī ocarbide simahiki i ka 8693HRA, ka mea like me 6981HRC.Loaʻa iā ia ka paʻakikī kiʻekiʻe o 900-1000 ° C a me ke kūpaʻa maikaʻi.Hiki i ka wikiwiki o ka ʻoki ʻana ke 4-7 mau manawa ma mua o ke kila mea hana kiʻekiʻe, hiki ke hoʻonui ʻia ke ola lawelawe e 5-80 mau manawa, a hiki ke ʻoki i nā mea paʻakikī me ka paʻakikī a hiki i 50HRC.2) Ka ikaika kiʻekiʻe, ka elasticity kiʻekiʻe ʻO ka ikaika compressive o ka carbide cemented e like me 6000MPa, a ʻo ka modulus o ka elasticity (4-7) × 105MPa, ʻoi aku ka nui ma mua o ke kila kiʻekiʻe.Eia nō naʻe, ʻoi aku ka maʻalahi o kona ikaika flexural, mai 1000 a 3000 MPa.3) Kūleʻa maikaʻi i ka corrosion a me ka oxidation kū'ē Kū'ē i ka ea, ka waikawa, ka alkali a me nā meaʻino'ē aʻe,ʻaʻole maʻalahi ka oxidize.4) Haʻahaʻa haʻahaʻa o ka hoʻonui laina I ka wā o ka hana, paʻa ke ʻano a me ka nui.5) ʻAʻohe hana hou a wili hou i nā mea i hoʻoheheʻe ʻia.Ma muli o ka paʻakikī kiʻekiʻe loa a me ka brittleness ocarbide sima, ʻAʻole hiki ke ʻoki ʻia a reground paha ma hope o ka hana ʻana a me ka sintering pauka.I ka wā e pono ai ka hana hou ʻana, hiki ke hoʻohana ʻia ka mīkini hoʻokuʻu uila, ʻoki uwea, electrolytic grinding, etc.ʻO nā ana, i hana pinepine ʻia me ka carbide cemented, hoʻopaʻa ʻia, hoʻopili ʻia, a paʻa ʻia paha me ka mīkini i ke kino mea hana a make paha.
