Iiblade zeTungsten Carbide
Ngokukhethwa kodidi olufanelekileyo, iiblade ze-tungsten carbide ezinobukhulu be-submicron grain zinokulolwa zibe ngumphetho we-razor ngaphandle kokuba buthathaka obuhlala bunxulunyaniswa ne-carbide eqhelekileyo. Nangona ingenakumelana nokutsha njengentsimbi, i-carbide ayigugi kakhulu, inobunzima obulingana ne-Rc 75-80. Ubomi beblade bunokuba yi-50X ubuncinane iintsimbi zeblade eziqhelekileyo bunokulindelwa ukuba kuthintelwe ukuqhekeka nokuqhekeka.
Njengakwimeko yokukhetha intsimbi, ukukhetha i-tungsten carbide (WC) ekumgangatho ophezulu yinkqubo enzima ebandakanya ukhetho oluchanekileyo phakathi kokuxhathisa ukuguguleka kunye nokuqina/ukuxhathisa ukushaqeka. I-tungsten carbide enesamente yenziwa ngokusila (kubushushu obuphezulu) indibaniselwano ye-tungsten carbide powder kunye ne-cobalt ephuhliweyo (Co), isinyithi esithambileyo esisebenza njenge-"binder" yamasuntswana e-tungsten carbide aqinileyo kakhulu. Ubushushu benkqubo yokusila abubandakanyi ukusabela kwezinto ezimbini, kodwa kunoko bubangela ukuba i-cobalt ifikelele kwimeko ephantse ibe lulwelo kwaye ibe njenge-glue matrix egqumayo yamasuntswana e-WC (angachaphazeleki bubushushu). Iiparamitha ezimbini, ezizezi umlinganiselo weCobalt kwi-WC kunye nobungakanani bamasuntswana e-WC, zilawula kakhulu iipropati zezinto ezininzi zesiqwenga se-"tungsten carbide enesamente" esiveliswayo.
Ukuchaza ubungakanani obukhulu be-WC particle kunye nepesenti ephezulu yeCobalt kuya kuvelisa inxalenye enganyangekiyo kakhulu (kwaye inamandla aphezulu empembelelo). Okukhona ubukhulu be-WC grain bucolekile (ngoko ke, indawo engaphezulu ye-WC ekufuneka igqunywe yiCobalt) kwaye iCobalt ingasetyenziswa kangako, kokukhona inxalenye ephumayo iya kuba nzima kwaye ingagugi. Ukuze ufumane ukusebenza okuhle kakhulu kwi-carbide njengesixhobo seblade, kubalulekile ukuphepha ukusilela komphetho kwangethuba okubangelwa kukuqhekeka okanye ukwaphuka, ngelixa ngaxeshanye kuqinisekiswa ukumelana nokuguguleka okufanelekileyo.
Njengombandela osebenzayo, ukuveliswa kwemiphetho yokusika ebukhali kakhulu, ene-engile ebukhali kuthetha ukuba kusetyenziswe i-carbide ecolekileyo kwiindlela zokufaka iiblade (ukuthintela ii-nicks ezinkulu kunye nemiphetho erhabaxa). Ngenxa yokusetyenziswa kwe-carbide enobukhulu obuphakathi be-1 micron okanye ngaphantsi, ukusebenza kwe-carbide blade; ngoko ke, ichaphazeleka kakhulu yi-% yeCobalt kunye ne-edge geometry echaziweyo. Usetyenziso lokusika olubandakanya imithwalo yoxinzelelo ephakathi ukuya kwephezulu lujongwa ngcono ngokuchaza i-12-15% yeCobalt kunye ne-edge geometry ene-edge angle ebandakanyiweyo malunga ne-40º. Usetyenziso olubandakanya imithwalo elula kwaye lubeka ixabiso eliphantsi kubomi be-blade ende lukhetho olufanelekileyo lwe-carbide equlethe i-6-9% ye-cobalt kwaye ine-edge angle ebandakanyiweyo kuluhlu lwe-30-35º.
I-HUAXIN CARBIDE ikulungele ukukunceda ekufezekiseni ulungelelwaniso olufanelekileyo lweempawu eziya kukuvumela ukuba ufumane ukusebenza okuphezulu kwiiblade zakho ze-carbide.
I-HUAXIN CARBIDE inikezela ngeencakuba zokunqumla iikhabhide ezigcweleyo
