I-Cemented carbide yimathiriyeli ye-alloy eyenziwe ngeekhompawundi ezinzima zesinyithi esiphikisayo kunye neentsimbi ezidibeneyo ngenkqubo ye-metallurgy powder. Idla ngokwenziwa ngezinto zokudibanisa ezithambileyo (ezifana necobalt, nickel, intsimbi okanye umxube wezi zinto zingasentla) kunye nemathiriyeli eqinileyo (efana netungsten carbide, molybdenum carbide, tantalum carbide, chromium carbide, vanadium carbide, titanium carbide okanye imixube yazo).
I-carbide enesamente inoluhlu lweempawu ezibalaseleyo, ezinjengokuqina okuphezulu, ukuxhathisa ukunxiba, ukomelela okulungileyo kunye nokuqina, ukumelana nobushushu, ukuxhathisa ukubola, njl., ngakumbi ubunzima bayo obuphezulu kunye nokumelana nokunxiba, okuhlala kungatshintshi nakwi-500 ℃ kwaye kusenobunzima obuphezulu kwi-1000 ℃. Kwizinto zethu eziqhelekileyo, ubunzima buvela phezulu ukuya phantsi: idayimane e-sintered, i-cubic boron nitride, i-cermet, i-carbide ene-cemented, i-high-speed steel, kunye nokuqina ukusuka phantsi ukuya phezulu.
I-carbide ene-cemented isetyenziswa ngokubanzi njengezixhobo zokusika izixhobo, ezifana nezixhobo zokujika, izixhobo zokusila, iiplani, i-drill bits, ii-cutters ezikruqulayo, njl., ukusika isinyithi, isinyithi esingenawo isinyithi, iiplastiki, imicu yeekhemikhali, igraphite, iglasi, ilitye kunye nentsimbi eqhelekileyo, kunye nokusika intsimbi enganyangekiyo ubushushu, intsimbi, intsimbi ephezulu yemanganese kunye nezinye izinto ezinzima kumatshini, intsimbi.
I-carbide enesamente inobunzima obuphezulu, amandla, ukuxhathisa ukunxiba kunye nokumelana nokubola, kwaye yaziwa ngokuba "ngamazinyo oshishino". Isetyenziselwa ukwenza izixhobo zokusika, izixhobo zokusika, izixhobo ze-cobalt kunye namalungu angagungqiyo. Isetyenziswa kakhulu kwishishini lomkhosi, i-aerospace, machining, isinyithi, ukugrumba ioyile, izixhobo zemigodi, unxibelelwano lwe-elektroniki, ulwakhiwo kunye namanye amacandelo. Ngophuhliso lwamashishini asezantsi, imfuno yentengiso ye-carbide enesamente iyanda. Kwaye kwixesha elizayo, ukuveliswa kwezixhobo zobugcisa obuphezulu kunye nezixhobo, inkqubela phambili yenzululwazi kunye neteknoloji kunye nophuhliso olukhawulezayo lwamandla enyukliya luya kwandisa kakhulu imfuno yeemveliso ze-carbide ezine-cemented kunye nomxholo wobugcisa obuphezulu kunye nozinzo oluphezulu.
Ngo-1923, i-schlerter yaseJamani yongeza i-10% - 20% ye-cobalt kwi-tungsten carbide powder njenge-binder, kwaye yenza i-alloy entsha ye-tungsten carbide kunye ne-cobalt. Ukuqina kwayo kukwesibini emva kwedayimane, eyeyona carbide yokuqala eyenziwe ngesamente emhlabeni. Xa usika insimbi ngesixhobo esenziwe ngolu hlobo, i-blade iya kunxiba ngokukhawuleza, kwaye i-blade iya kuqhekeka. Kwi-1929, i-schwarzkov yase-United States yongeza inani elithile le-carbides edibeneyo ye-tungsten carbide kunye ne-titanium carbide kwi-original composition, eyaphucula ukusebenza kwezixhobo zokusika isinyithi. Le yenye impumelelo kwimbali yophuhliso lwekhabhide enesamente.
I-carbide ene-cemented ingasetyenziselwa ukwenza izixhobo zokwemba amatye, izixhobo zokomba, izixhobo zokomba, izixhobo zokulinganisa, iinxalenye ezingagugiyo, i-abrasives yentsimbi, ii-cylinder liners, iibheringi ezichanekileyo, ii-nozzles, iimolds ze-hardware (ezifana nokubunjwa kocingo, ukubunjwa kwebholiti, ukubunjwa kwe-nut, kunye ne-mold egqwesileyo ye-carbide yangaphambili. iimbumba).
Kwiminyaka engamashumi amabini edlulileyo, i-carbide efakwe ngesamente iye yavela. Ngowe-1969, iSweden yaphuhlisa ngempumelelo isixhobo se-titanium carbide coated. I-substrate yesixhobo yi-tungsten titanium cobalt cemented carbide okanye i-tungsten cobalt cemented carbide. Ubunzima be-titanium carbide coating phezu komhlaba buyi-microns ezimbalwa kuphela, kodwa xa kuthelekiswa nezixhobo ze-alloy zophawu olufanayo, ubomi benkonzo bandiswa ngamaxesha angama-3, kwaye isantya sokusika sande ngama-25% - 50%. Isizukulwana sesine sezixhobo zokugquma sabonakala kwiminyaka yee-1970, engasetyenziselwa ukusika izinto ezinzima ukuzisebenzisa.
