Yintoni tungsten carbide?

I-tungsten carbideis ekwabizwa ngokuba yi-cemented carbide. I-Tungsten carbide luhlobo lwemathiriyeli ye-alloy ene-refractory tungsten (W) impahla ye-micron powder njengesona sithako siphambili, ngokubanzi sihamba ngomlinganiselo phakathi kwe-70% -97% yobunzima bubonke, kunye ne-Cobalt (Co), i-Nickel (Ni), okanye i-Molybdenum. (Mo) njengomdibanisi.

Okwangoku, iW ikwimo yeWCisetyenziswa ikakhulu kwimveliso ye-carbide enesamente.i-tungsteni-carbide yimathiriyeli eyenziwe ngokudibanisa amaqhekeza e-WC anzima kakhulu kwi-cobalt enzima (Co) ye-binder matrix nge-liquid-phase sintering. Kwiqondo lokushisa eliphezulus, I-WC inyibilika kakhulu kwi-cobalt, kunye ne-cobalt binder yolwelo inokwenza i-WC ibe nokumanzisa okulungileyo, okukhokelela kubumbano oluhle kunye nolwakhiwo olungelulo lwepore kwinkqubo ye-liquid-phase sintering. Ke, i-tungsten carbide inoluhlu lweepropathi ezigqwesileyo, ezinje:

*ubunzima obuphezulu:Mohs’ubulukhuni busetyenziswa ikakhulu kuhlelo lweminerali. Isikali seMorse sisuka1ukuya ku10(Inani elikhulu, kokukhona liphezulu ubulukhuni).Ubulukhuni be-Mohs be-tungsten carbide yi9 ukuya ku-9.5,Iqhayisa kwinqanaba lobulukhuni okwesibini ukuya kwidayimaneobubunzima obubu-10.

*ukumelana nokunxiba: Ukuphakama kobunzima, ngcono ukuxhathisa ukunxiba kwe-tungsten carbide

*ukumelana nobushushu: Ekubeni inamandla aphezulu kwiqondo lokushisa eliphezulu kunye ne-coefficient ephantsi yokwandiswa kwe-thermal, iyona nto ilungileyo yezinto eziluhlaza zezixhobo zokusika eziza kusetyenziswa kwindawo yokushisa ephezulu kunye nesantya esiphezulu.

*CUkumelana ne-orrosion: I-Tungsten carbide yinto ezinzile kakhulu, engenako ukunyibilika emanzini, i-hydrochloric acid okanye i-asidi ye-sulfuric. Ukongezelela, akunakwenzeka ukwenza isisombululo esiqinileyo esinezinto ezahlukahlukeneyo, kwaye sinokugcina iimpawu ezizinzileyo nakwiindawo ezinzima.

Ngokukodwa ubulukhuni bayo obuphezulu kunye nokumelana nobushushu, okuhlala kungatshintshi nakwi-1000 ℃. Ngoncedo oluninzi, i-tungsten carbide inokusetyenziselwa ukwenza izixhobo zokusika, iimela, izixhobo zokomba, kunye neendawo ezinganxibiyo, kwaye isetyenziswa ngokubanzi kwishishini lezomkhosi, i-aerospace, ukusetyenzwa koomatshini, isinyithi, ukugrumba i-petroleum, izixhobo zemigodi, i-elektroniki. unxibelelwano, ulwakhiwo, kunye namanye amacandelo. Yiyo loo nto yaziwa ngokuba "amazinyo oshishino".

I-Tungsten carbide iphindwe ka-2-3 njengentsimbi kwaye inamandla acinezelayo ukodlula zonke iintsimbi ezaziwayo ezinyibilikisiweyo, ezityhidiweyo, kunye nezibunjiweyo. Ixhathisa kakhulu kwi-deformation kwaye igcina uzinzo lwayo zombini ibanda kakhulu kunye namaqondo obushushu ashushu. Ukuchasana kwayo neempembelelo, ukuqina, kunye nokuchasana ne-galling / abrasions / erosions iyingqayizivele, ihlala ukuya kumaxesha angama-100 ubude kunentsimbi kwiimeko ezinzima. iqhuba ubushushu ngokukhawuleza kakhulu kunentsimbi yesixhobo. I-tungsten carbideinokuphoswa kwaye icinywe ngokukhawuleza ukwenza ulwakhiwo lwekristale olunzima kakhulu.

Ngophuhliso lweikumashishini asezantsi, imfuno yemarike ye-tungsten carbide iyanda. Kwaye kwixa elizayo, ukwenziwa kwezixhobo zetekhnoloji ephezulu yezixhobo, inkqubela phambili yesayensi kunye netekhnoloji, kunye nophuhliso olukhawulezayo lwamandla enyukliya luya kwandisa kakhulu imfuno yeemveliso ze-carbide ezinomxholo ophezulu kunye nomgangatho ophezulu.-uzinzo umgangatho.
