Carbide extruded brass

1) Ubulukhuni obugqwesileyo kunye nokumelana nokunxiba Kwiqondo lobushushu begumbi, ukuqina kwei-carbide enesamenteinokufikelela kwi-8693HRA, elingana ne-6981HRC.Inobunzima obuphezulu be-900-1000 ° C kunye nokumelana nokunxiba kakuhle.Isantya sokusika sinokuba ngamaxesha angama-4-7 ngokukhawuleza kunesixhobo sensimbi esinesantya esiphezulu, ubomi benkonzo bunokwandiswa ngamaxesha angama-5-80, kwaye sinokunqumla izinto ezinzima kunye nobunzima ukuya kwi-50HRC.I-2) Amandla aphezulu, i-elasticity ephezulu Amandla anyanzeliswayo e-carbide ene-cemented aphezulu njenge-6000MPa, kwaye i-modulus ye-elasticity yi (4-7) × 105MPa, enkulu kuneyentsimbi ephezulu.Nangona kunjalo, amandla ayo okuguquguquka aphakathi, ukusuka kwi-1000 ukuya kwi-3000 MPa.I-3) Ukumelana nokugqwesa kwe-corrosion kunye nokumelana ne-oxidation Ukumelana nomoya, i-asidi, i-alkali kunye nezinye i-corrosion, akulula ukuyi-oxidize.4) I-coefficient ephantsi yokwandiswa komgca Ngexesha lokusebenza, imilo kunye nobukhulu buhlala buzinzile.5) Akukho okunye ukusetyenzwa okanye ukugaywa kwakhona kwezinto ezibunjiweyo.Ngenxa yobunzima obuphezulu kakhulu kunye nokuqina kwei-carbide enesamente, ayinakunqunyulwa okanye iphinde igaywe emva kokwenziwa kwesinyithi somgubo kunye nokuntywila.Xa ukuphinda kusetyenzwe kwakhona kuyimfuneko, kuphela ukukhutshwa kombane, ukusika i-wire, ukugaya i-electrolytic, njl njl.Imilinganiselo, edla ngokwenziwa ngesamente ye-carbide, ibotshiwe, incamatheliswe, okanye ibotshelelwe ngomatshini kumzimba wesixhobo okanye iyafa.
