Indlela yokukhetha izixhobo ezifanelekileyo zokusika idayimani
Xa kufikwa ekufezekiseni ukusebenza okuphezulu kwimishini, ukukhetha izixhobo zokusika idayimani kubalulekile. Iidayimani zekristale enye, iidayimani zePCD (okanye iPCD/CC), kunye neCVD zezona zinto ziphambili zokwenza izixhobo zokusika ezifana nezixhobo zokujika, izixhobo ezibophayo, ii-drill bits, ii-reamers, ii-milling cutters, izixhobo zokujonga iprofayili, kunye nee-saw blades. Ukukhetha izinto zedayimani ezifanelekileyo kubalulekile, kungekuphela nje ekuhlangabezaneni neemfuno zobugcisa kodwa nasekuqinisekiseni ukuba imeko yezoqoqosho iyasebenza kunye nokuzinza kokusingqongileyo.
Kutheni Ukhetha Izinto zePCD kunye nePCD/CC?
I-PCD kunye ne-PCD/CC zezona zinto zibalulekileyo kwimveliso yanamhlanje, ezidume ngokuguquguquka kwazo okugqwesileyo. Ezi zinto azipheleli nje kwizicelo zemveli zoomatshini; zisetyenziswa kakhulu kumashishini afana neemoto, i-aerospace, i-high-speed rail, i-petroleum, iikhemikhali, ulwakhiwo, kunye nokusebenza ngomthi. Kwicandelo leemoto kunye neebhayisekile, i-PCD kunye ne-PCD/CC zigqwesile ekuchweniseni izinto ezinxitywa kakhulu, kubandakanya iziketi zepiston ze-aluminium alloy, imingxunya yepin, iibhloko ze-cylinder, ii-gearbox, kunye nee-carburetors. Ezi zinto zihlala zine-aluminium matrix composites enomxholo ophezulu we-silicon (Si > 12%), apho amasuntswana aqinileyo (njenge-SiC) enza imingeni emikhulu yokunxitywa. Izixhobo ze-carbide zemveli ziyalwa nezi zinto zinzima, nto leyo ebangela ukuba izixhobo zihlale ixesha elifutshane kwaye iindleko zemveliso zinyuke.
Ukusebenza Okugqwesileyo kunye Izixhobo zePCD
Ukusebenzisa izixhobo ze-PCD (okanye ze-PCD/CC) zokulungisa i-carbon fiber kunye ne-fiberglass reinforced plastics (FRP) kuzisa iingenelo ezimangalisayo: iitships ziyancitshiswa zibe ngumgubo, amaqondo obushushu okusika ahlala ephantsi, kwaye ubude bokusika buyamangalisa ngokuphindwe kalishumi kunezixhobo ze-K-class carbide eziqhelekileyo, kunye namazinga okuguguleka angaphantsi kwesithathu kunezinye izixhobo ze-carbide. Izixhobo ze-PCD zikwalungele ukulungisa ii-alloys eziqinileyo ezifakwe ngaphambili kunye nezinto ezingensimbi ezinganyangekiyo ezifana ne-ceramics, irabha, i-graphite, iglasi, kunye neenkuni ezihlala ixesha elide.
Ukusebenza kwezixhobo ze-PCD kuchaphazeleka kukusetyenziswa kwazo kunye nenkqubo ethile yokugaya. Ukukhetha uhlobo olufanelekileyo kunye nobukhulu beesuntswana kubalulekile ukuze ufumane iziphumo ezilungileyo. I-Boreas inikezela ngeendlela ezahlukeneyo Iiblade zePCD, kuquka i-LTM2200, i-LTM004, i-LTM10, kunye ne-LTM90, ezinobukhulu obuphakathi be-1μm (encinci), i-4μm/10μm (ephakathi), kunye ne-25μm (erhabaxa). Ubukhulu be-grain ezinkulu buphucula ukuxhathisa ukuguguleka kwaye buyandisa ubomi besixhobo, kodwa bunokukhokelela kumngcipheko wokusika orhabaxa. Ii-grain eziphakathi zisebenza njengeendlela ezahlukeneyo zokulungisa ngokubanzi, ngelixa izixhobo ezicoliweyo zibonelela ngomgangatho ophezulu womphezulu ngenxa ye-radii yazo encinci yomphetho.
NgeBoreas, ungalindela ubuchwepheshe obuphambili kunye nezisombululo ezenzelwe wena ngokweemfuno zakho zoomatshini. Sihlala siphucula izixhobo zethu zePCD, sibonelela ngobukhulu beenkozo ukusuka kwi-2-30μm, siqinisekisa ukuba ufumana izixhobo ezifanelekileyo kwizicelo zakho. Khetha iiBoreas zomgangatho ongenakuthelekiswa nanto kunye nokusebenza kakuhle kwezixhobo zokusika iidayimani, kwaye uphakamise amandla akho oomatshini abe phezulu!
