Inkqubela phambili kubuchwepheshe bonyango lomphezulu ichaza ngokutsha ukusebenza kweizixhobo zokubhoboza ze-carbide, ethembisa inzuzo enkulu ekusebenzeni kakuhle, umgangatho wokugqiba, kunye nobude bexesha lezixhobo kubavelisi abachanekileyo kwihlabathi liphela. Sisebenzisa inkqubo ephucukileyo yokudlulisa amandla eyenziwe eJamani, isizukulwana samva nje sezixhobo sinikeza i-paradox eyahlukileyo: umda oguqulwe ngemicroscope osika ubukhali, ukhawuleza, kwaye ucocekile kunangaphambili.
Kangangamashumi eminyaka, ukuphishekela ubukhali obupheleleyo kwizixhobo ze-carbide bekusoloko kukhokelele ekubeni sengozini enkulu: imiphetho ebuthathaka, ebhityileyo njengerazor enokuqhekeka kancinci kunye nokuguguleka ngokukhawuleza, ingakumbi xa kukho imisebenzi yokubhoboza emininzi kwizixhobo ezinzima ezifana neentsimbi eziqinileyo, ii-superalloys, kunye neentsimbi eziphosiweyo. Oku kubuthathaka kubangele ukugqitywa okungahambelaniyo, ukwanda kokumelana nokusika, ukusilela kwezixhobo ngaphambi kwexesha, kunye nesiganeko esidanisayo "sokusika iithumba" - umda owakhelwe phezulu (BUE) apho izinto zokusebenza zidityaniswa kwisixhobo, ukusebenza okuwohlokayo kunye nomgangatho womphezulu.
Inkqubo entsha yokuphucula ulwelo ijongana ngqo nale ngxaki. Idlula ngaphaya kokusetyenziswa okulula kokujikeleza umphetho okanye ukusetyenziswa kwengubo yendabuko, obu buchwephesha baseJamani bubandakanya unyango olulawulwa kakhulu ngamakhemikhali kunye noomatshini. Itshintsha ngokuchanekileyo i-micro-geometry yomphetho osikiweyo kwinqanaba le-sub-micron.
Isayensi ye-"Dulling" eLawulwayo:
Ukwenziwa kweMicro-Bevel ekujoliswe kuyo: Endaweni yokushiya umphetho obukhali ngokweathom (nobuthathaka), le nkqubo idala umphetho omncinci okanye iradius ehambelanayo ngokumangalisayo ecaleni komphetho osikiweyo. Le micro-bevel yenzelwe ukuba ibe nkulu ngokwaneleyo ukususa iindawo ezibuthathaka nezinokuqhekeka.
Ukususa iiMicro-Defects: Le nkqubo ilungisa kwaye isuse iingxaki ezincinci kunye neendawo zoxinzelelo ezishiyekileyo kwinkqubo yokusila, idala indawo yokutshintsha engenaziphene ngasemva komphetho wokwenyani.
Ukuqina Komphetho Ophuculweyo: Isiphumo sisiphumo somphetho ogcina ubukhali obukhethekileyo bokusika kodwa unamandla anyukileyo kunye nokumelana nokuqhekeka nokuqhekeka.
Iingenelo Zokusebenza Kwihlabathi Lokwenyani:
Olu luhlu olucwangcisiweyo luguqulela kwiingenelo ezibonakalayo kumgangatho wevenkile:
Ukusika "Okubukhali Nokukhawuleza": Ngokuchasene nengqiqo, umphetho ongasebenziyo awunayo impembelelo yokusikwa eninzi kakhulu. Ngokuthintela i-micro-chipping kunye nokuqaliswa kwe-BUE, isixhobo sigcina i-geometry yaso eyilwe kunye nobukhali ixesha elide. Oku kuvumela isantya esiphezulu somatshini wokugaya (Vc) kunye namazinga okutya (f) ngaphandle kokunciphisa ukuthembeka komphetho, okunyusa ngokuthe ngqo imveliso.
Ukugqitywa Okuphezulu Okuphezulu: Ukususwa kwe-micro-chipping kunye nomphetho owakhelwe phezulu kubalulekile ekufezekiseni ukugqitywa okugqwesileyo komphezulu. Isenzo sokusika esizinzileyo nesigudileyo senza iibhore ezinexabiso eliphantsi kakhulu leRa, zihlala zisusa imisebenzi yokugqiba yesibini. Ilifa "lenkqubo yokugaya yaseJamani" ligxininisa oku kuphishekela ukuchaneka okuphezulu kunye nokugqibelela komphezulu.
Ii-Tumors eziNciphisiweyo zokuSika (BUE): Ngokulungisa umphetho nokususa iindawo zoxinzelelo, i-passivation inciphisa iindawo ze-nucleation apho izinto zokusebenza zinokunamathela khona. Xa zidityaniswe nesenzo sokusika esithambileyo kunye nokungqubana okuncitshisiweyo, oku kunciphisa kakhulu ukwakheka komphetho owakhelweyo, kuqinisekisa ukuhamba kwe-chip rhoqo kunye namandla okusika azinzileyo.
Ubomi Besixhobo Esandisiweyo: Amandla aphuculweyo kunye nokumelana neendlela zokuqhekeka kunye nokuguguleka ziguqulela ngokuthe ngqo kubomi besixhobo obuhlala ixesha elide. Izixhobo zisebenza rhoqo kwiindawo ezininzi ngaphambi kokuba zifune ukutshintshwa okanye ukulungiswa kwakhona, nto leyo enciphisa ixesha lokungasebenzi kunye neendleko zezixhobo ngenxalenye nganye.
Ukuthembeka kweNkqubo eNgcono: Ukunciphisa ukumelana nokusika kunye nokucinezelwa kweBUE kukhokelela kwiimeko zomatshini eziqikelelweyo nezizinzileyo. Oku kunciphisa ukungcangcazela, kuphucula ukuchaneka kobukhulu, kwaye kunciphisa umngcipheko weendawo ezilahliweyo ngenxa yokusilela kwesixhobo okanye umgangatho ophantsi womphezulu.
Impembelelo kunye nokuFumaneka kweShishini:
Le teknoloji iluncedo kakhulu kwizicelo ezifuna amandla ezixhaphakileyo kwiindawo zomoya, umbane weemoto, ukwenziwa kwezixhobo zonyango, kunye namacandelo amandla, apho imingxunya enzulu necacileyo yezinto ezinzima iqhelekile. Abavelisi abanengxaki yomgangatho wokugqitywa, ukungangqinelani kobomi bezixhobo, okanye imiba yomphetho owakhiweyo ngabona bangenelwayo.
