Icandelo lokuqala: Yintoni i-carbide materials?
I-carbide eyenziwe ngesamente yenziwe nge-tungsten carbide kunye ne-cobalt.I-Tungsten carbide yimpahla enendawo ephezulu yokunyibilika.Kufuneka igaywe ibe ngumgubo kwaye iveliswe ngokutshiswa kobushushu obuphezulu kunye nokuqiniswa, kwaye i-cobalt yongezwa njengento ebophelelayo.I-Tungsten ivela ikakhulu eTshayina, eRashiya naseMzantsi Korea, ngelixa i-cobalt ivela eFinland, eCanada, e-Australia naseCongo.Ngoko ke, ukwenza i-alloys enzima kakhulu kufuna intsebenziswano yehlabathi jikelele ukusebenzisa le nto imangalisayo kwiinkalo ezahlukeneyo. titanium-cobalt (niobium).Eyona nto isetyenziswa kakhulu kwimveliso yi-tungsten-cobalt kunye ne-tungsten-titanium-cobalt cemented carbide.
Ukuze wenze i-alloy enzima kakhulu, kuyimfuneko ukugaya i-tungsten carbide kunye ne-cobalt ibe ngumgubo ococekileyo, kwaye utshise kwaye uqiniswe kwiqondo lokushisa eliphezulu (1300 ° C ukuya kwi-1500 ° C) ukuqinisa izinto.I-Cobalt yongezwa njengento edibeneyo yokunceda i-tungsten carbide particles inamathele omnye komnye.Isiphumo sisinyithi esinesigxina esinendawo yokunyibilika kwe-2900 ° C, eyenza ikwazi ukumelana nokushisa okuphezulu kwaye ifaneleke ngokufanelekileyo kwizicelo zokushisa okuphezulu.
Icandelo lesibini: Yintoni ukusetyenziswa kwezinto ze-carbide?
I-carbide ene-cemented inoluhlu olubanzi lwezicelo.Kwintsimi yokwenziwa kwemizi-mveliso, isetyenziswa ngokubanzi ekwenzeni izixhobo zokusika zokucutshungulwa kwesinyithi njengezixhobo zokugaya i-CNC, oomatshini bokugaya i-CNC, kunye ne-CNC lathes.Ukongeza, ingasetyenziselwa ukwenza imifuziselo yeetoti ze-aluminium ezifana nekofu enkonkxiweyo kunye neziselo, i-powder mold molds ye-injini ye-automotive parts (i-sintered parts), kunye ne-molds ye-electronic components ezifana neeselfowuni.
Ngokubhekiselele kwimveliso kunye nokucubungula, ukubaluleka kwe-alloy enzima kakhulu kuyabonakala.Ngenxa yokuqina kwayo okugqwesileyo kunye namandla, ii-alloys ezigqwesileyo zisetyenziswa kakhulu kwizixhobo zomatshini ezifana nezixhobo zokusika isinyithi, izixhobo zokomba, oomatshini bokugaya kunye neentambo.Ukongeza, ingasetyenziselwa ukwenza i-aluminium inokubumba ikofu enkonkxiweyo kunye neziselo, i-powder mold molds ye-injini ye-automotive parts (i-sintered parts), kunye nokubumba kumacandelo e-elektroniki afana neefowuni eziphathwayo, njl.
Nangona kunjalo, i-alloys ye-superhard ayikhawulelwanga kwintsimi yesinyithi kunye nokuvelisa.Isenokusetyenziselwa ukutyumza amatye aqinileyo, njengokwakhiwa kweetonela ikhaka, nokusikwa kweendlela zeasphalt nezinye iindawo.Ukongeza, ngenxa yeempawu zayo ezibalaseleyo, iialloyi ezinobunzima obuphezulu zinokusetyenziswa ngokubanzi kwezinye iindawo zeCNC machining.Umzekelo, izixhobo zotyando ezisetyenziswa kwicandelo lezonyango, iibhulethi kunye neentloko zemfazwe kwindawo yomkhosi, amacandelo eenjini kunye neeblade ze-injini yenqwelomoya kwindawo ye-aerospace, njl.
Ukongeza kwisicelo kwishishini, ii-alloys ezinzima kakhulu zidlala indima kwinkalo yophando lwesayensi.Ngokomzekelo, ingasetyenziselwa ukwenza ii-diffraction rods kwi-X-ray kunye nophando lwe-optical, kwaye njenge-catalyst ekufundeni kweekhemikhali.
Icandelo lesithathu: Yintoni ubunzima kumatshini wenxalenye ye-carbide?
Ukulungiswa kwe-carbide ene-cemented akulula kwaye kukho ubunzima obuninzi.Okokuqala, ngenxa yobunzima bayo obuphezulu kunye nokuqina kwayo, iindlela zokulungisa zemveli zihlala zinzima ukuhlangabezana neemfuno kwaye zinokukhokelela ngokulula kwiziphene ezifana nokuqhekeka kunye nokuguqulwa kwemveliso.Okwesibini, i-carbide ene-cemented isetyenziswe kwiindawo eziphezulu, ngoko ke iimfuno zokuchaneka komatshini ziphezulu kakhulu.Ngethuba lenkqubo yokucubungula, izinto ezininzi kufuneka zithathelwe ingqalelo, njengezixhobo zokusika, izixhobo, iiparitha zenkqubo, njl., Ukuqinisekisa ukuchaneka kwemveliso.Ekugqibeleni, iimfuno zomgangatho ophezulu we-carbide ene-cemented nazo ziphezulu kakhulu.Ngenxa yobunzima bayo obukhulu, umphezulu wonakaliswa lula, ngoko ke iindlela ezikhethekileyo zokucwangcisa kunye nezixhobo (ezifana ne-ultra-precision grinders, i-electrolytic polishers, njl.) kufuneka zisetyenziswe ukuqinisekisa umgangatho ophezulu.
Ngamafutshane, i-carbide ene-cemented isanda kusetyenziswa kwi-CNC machining, idlala indima ephambili ekuphuculeni ukusebenza kakuhle kwemveliso kunye nomgangatho wemveliso kumatshini, i-electronics, iikhemikhali, i-aerospace kunye namanye amashishini.GPM inezixhobo zokusebenza eziphambili kunye nobuchwepheshe obunokuqhuba iinxalenye ze-supercarbide ngokufanelekileyo nangokuchanekileyo. .Inkqubo yokulawula umgangatho ongqongqo ngexesha lenkqubo yokucubungula iqinisekisa ukuba inxalenye nganye ihlangabezana neemfuno kunye nemigangatho yabathengi.
