Njengoba nje endabeni yokukhethwa kwensimbi, ukukhetha izinga elifanelekile le-tungsten carbide (WC) kuyinqubo eyinkimbinkimbi ehlanganisa ukukhetha okusengozini phakathi kokumelana nokugqoka kanye nokuqina/ukumelana nokushaqeka. I-tungsten carbide enosimende yenziwa ngokufakwa (emazingeni okushisa aphezulu) inhlanganisela ye-tungsten carbide powder ne-cobalt eyimpushana (Co), insimbi edonsayo esebenza "njengesibopho" sezinhlayiya ze-tungsten carbide eziqine kakhulu. Ukushisa kwenqubo ye-sintering akubandakanyi ukusabela kwezingxenye ezingu-2, kodwa kunalokho kubangela ukuthi i-cobalt ifinyelele esimweni soketshezi oluseduze futhi ibe njenge-encapsulating glue matrix yezinhlayiya ze-WC (ezingathintwa ukushisa). Amapharamitha amabili, okuyisilinganiso se-Cobalt kuya ku-WC kanye nosayizi wezinhlayiyana ze-WC, alawula ngokuphawulekayo izakhiwo zempahla eyinqwaba yocezu oluphumayo "lwe-tungsten carbide".

Ukucacisa usayizi omkhulu wezinhlayiyana ze-WC kanye nephesenti eliphezulu le-Cobalt kuzoveza ingxenye ekwazi ukumelana nokushaqeka (namandla amakhulu omthelela). Uma usayizi wokusanhlamvu we-WC ucinene (ngakho-ke, indawo engaphezulu ye-WC okufanele igcotshwe nge-Cobalt) futhi uma i-Cobalt isetshenziswa kancane, ingxenye ewumphumela izoqina futhi imelane kakhulu. Ukuze uthole ukusebenza okuhle kakhulu ku-carbide njengento ye-blade, kubalulekile ukugwema ukwehluleka konqenqema ngaphambi kwesikhathi okubangelwa ukuchotshozwa noma ukuphuka, kuyilapho ngesikhathi esifanayo uqinisekisa ukumelana nokugqokwa okuphezulu.
Njengodaba olungokoqobo, ukukhiqizwa kwemiphetho yokusika ebukhali kakhulu, ene-engeli eqinile ibeka ukuthi kusetshenziswe i-carbide ecolekile ekufakweni kwe-blade (ukuze kuvinjwe ama-nick amakhulu nemiphetho emangelengele). Uma kubhekwa ukusetshenziswa kwe-carbide enosayizi ojwayelekile wokusanhlamvu we-micron engu-1 noma ngaphansi, ukusebenza kwe-carbide blade; ngakho-ke, ithonywa kakhulu yi-% ye-Cobalt kanye nejometri enqenqemeni ecacisiwe. Ukusika izinhlelo zokusebenza ezibandakanya ukushaqeka okumaphakathi kuya phezulu kusingathwa kangcono kakhulu ngokucacisa amaphesenti angu-12-15 e-Cobalt kanye nejiyomethri enqenqemeni ene-engeli enqenqemeni engaba ngu-40º. Izinhlelo zokusebenza ezibandakanya imithwalo elula futhi zibeka iprimiyamu ekuphileni kwe-blade ende zingamakhandidethi alungile e-carbide equkethe amaphesenti angu-6-9 e-cobalt futhi ene-engeli enqenqemeni ebangeni elingu-30-35º.
I-Tungsten Carbide iyinto ende egqoke i-blade etholakalayo ezinhlelweni eziningi zokusika. Siyibonile iguga kufika ku-75X isikhathi eside kunezinsimbi ezijwayelekile zensimbi. Uma udinga i-blade egqoke isikhathi eside, i-Tungsten Carbide imvamisa ikunikeza impilo yokugqoka oyidingayo ukuze ukhulise umkhiqizo wakho.
Ithuluzi le-Passion lisebenzisa kuphela i-Tungsten Carbide yekhwalithi ephezulu kakhulu ukuze kuqinisekiswe ukuthi amakhasimende ethu athola izindwani zokugqoka ezibukhali nezinde kakhulu. EyethuAma-Carbide Bladeszenziwe ngezinto ezibonakalayo ezine-Sub-Micron Grain Structure futhi zidlule kunqubo ye-HIP (Hot Isostatic Press) ukuze kuqinisekiswe ukuguga okude kakhulu nemiphetho ebukhali kakhulu. I-blade ngayinye ibuye ihlolwe ngaphansi kokukhuliswa kokulawulwa kwekhwalithi.
Kuyisimangaliso ukuthi impahla eluhlaza ye-carbide isuke ezinhlayiyeni zempushana iye emkhiqizweni oqedwe kancane wommese wezimboni, futhi isuka emkhiqizweni osuphelile iye ethuluzini elinembile kuyinqubo yokukhiqiza yobuciko. KhethaPASSION Tool®, khetha ifektri yekhwalithi ephezulu ye-WC, izokuzuzela amakhasimende aphezulu kakhulu.
