I-carbide enosimende iyingxubevange eyenziwe ngenhlanganisela eqinile yensimbi ephikisayo kanye nensimbi ebophayo ngenqubo ye-powder metallurgy.Inezici zokuqina okuphezulu, ukumelana nokugqoka, amandla kanye nokuqina.Ngenxa yezakhiwo zayo eziyingqayizivele, ngokuvamile isetshenziselwa ukwenza amathuluzi okumba amatshe, amathuluzi okumba, amathuluzi okumba, amathuluzi okulinganisa nokunye.Isetshenziswa kabanzi ku-petroleum negesi yemvelo, imboni yamakhemikhali, imishini yokwakha, ukulawula uketshezi kanye neminye imikhakha.I-carbide enosimende iyinto ecindezelwa yi-powder metallurgy.Namuhla, uChuangrui Xiaobian uzokwethula izinkinga ezinkulu ezimbalwa esivame ukuhlangana nazo ohlelweni lokucindezela, futhi ahlaziye kafushane izizathu.
1. Udoti ocindezelayo ovame kakhulu enqubweni yokucindezela i-carbide enosimende i-delamination
Ukuvela onqenqemeni lwebhulokhi yokucindezela, nge-engeli ethile endaweni yokucindezela, ukwakha isixhumi esibonakalayo esihlanzekile kubizwa ngokuthi i-delamination.Iningi lokwendlaleka liqala emakhoneni futhi lidlulele ku-compact.Isizathu se-delamination ye-compact ukucindezeleka kwangaphakathi okunwebekayo noma ukungezwani okunwebekayo ku-compact.Isibonelo, okuqukethwe kwe-cobalt yengxube kuphansi kakhulu, ubulukhuni be-carbide buphezulu, i-powder noma i-particle incinene, i-ejenti yokubumba incane kakhulu noma ukusabalalisa akufani, ingxube imanzi kakhulu noma yomile kakhulu, ukucindezela kokucindezela kukhulu kakhulu, isisindo seyunithi sikhulu kakhulu, futhi amandla okucindezela aphezulu kakhulu.Umumo webhulokhi uyinkimbinkimbi, ukuphela kwesikhunta kubi kakhulu, futhi indawo yetafula ayilingani, okungase kubangele i-delamination.
Ngakho-ke, ukuthuthukisa amandla e-compact kanye nokunciphisa ingcindezi yangaphakathi kanye nekhwela elibuyela emuva le-compact kuyindlela ephumelelayo yokuxazulula i-delamination.
2. Isimo sezinhlayiya ezingacindezelwanga (izinhlayiya ezibonisiwe) zizokwenzeka futhi ngesikhathi sokucindezela kwe-carbide enosimende.
Ngenxa yokuthi ubukhulu bezimbotshana ze-compact bukhulu kakhulu, abukwazi ukunyamalala ngokuphelele ngesikhathi senqubo ye-sintering, okuholela kuma-pores akhethekile asele emzimbeni we-sintered.Ama-pellets aqinile kakhulu, ama-pellets ama-coarse kakhulu, futhi izinto ezikhululekile zikhulu kakhulu;ama-pellets avulekile asakazwa ngokungalingani emgodini, futhi isisindo seyunithi siphansi.kungase kubangele uncompressed.
3. Enye into evamile yokucindezela imfucuza ekucindezelweni kwe-carbide enosimende ukuqhekeka
Isenzakalo sokuphuka okungajwayelekile kwendawo ku-compact kubizwa ngokuthi i-crack.Ngoba ukucindezeleka okuqinile ngaphakathi kwe-compact kukhulu kunamandla we-compact.Ukucindezeleka kwangaphakathi kwe-compact kuvela ekucindezelekeni kwangaphakathi okunwebekayo.Izinto ezithinta i-delamination nazo zithinta ukuqhekeka.Izinyathelo ezilandelayo zingathathwa ukuze kuncishiswe ukuvela kwemifantu: ukwandisa isikhathi sokubamba noma ukucindezela izikhathi eziningi, ukunciphisa ingcindezi, isisindo seyunithi, ukuthuthukisa ukwakheka kwesikhunta futhi kwandise ngokufanele ubukhulu besikhunta, ukusheshisa ijubane lokudiliza, ukwandisa i-ejenti yokubumba, futhi ikhulise ukuminyana kwenqwaba yezinto.
Yonke inqubo yokukhiqiza ye-carbide enosimende ibaluleke kakhulu.I-Zhuzhou Chuangrui Cemented Carbide Co., Ltd. isebenze ngokukhethekile ekukhiqizeni i-carbide enosimende iminyaka engu-18.Uma unemibuzo mayelana nokukhiqizwa kwe-carbide enosimende, sicela unake iwebhusayithi esemthethweni kaChuangrui.
