Impumelelo kwitekhnoloji yonyango lomphezulu kukuchaza ngokutsha ukusebenza kweizixhobo ezikruqulayo carbide, ethembisa iinzuzo ezibalulekileyo ekusebenzeni, umgangatho wokugqiba, kunye nobomi obude besixhobo kubavelisi abachanekileyo kwihlabathi jikelele. Ukusebenzisa inkqubo yokuqhubela phambili ephuhliswe eJamani, isizukulwana samva nje sezixhobo sizisa isiphithiphithi esikhethekileyo: umphetho oguquliweyo we-microscopically osika ubukhali, ngokukhawuleza, kwaye ucoceke kunangaphambili.
Kangangamashumi eminyaka, ukufuna ubukhali bokugqibela kwisixhobo se-carbide kudla ngokukhokelela ekubeni semngciphekweni obalulekileyo: imiphetho eethe-ethe, incakuba ebhityileyo ethanda ukutshiphukelwa kancinci kunye nokunxiba okukhawulezileyo, ngakumbi phantsi komthwalo onzima wokusebenza kwizinto ezomeleleyo ezifana neentsimbi eziqinileyo, ii-superalloys, kunye neentsimbi eziphosiweyo. Oku buthathaka kubangele ukugqibezela okungahambelaniyo, ukwanda kokuxhathisa ukusika, ukusilela kwesixhobo kwangaphambi kwexesha, kunye nemeko ekhathazayo "yokusika amathumba" - i-built-up edge (BUE) apho izixhobo zokusebenza zingena kwisixhobo, ukuthoba ukusebenza kunye nomgangatho womphezulu.
Inkqubo esanda kuphuculwa ijongana ngqo nalo mngeni. Ukuhamba ngaphaya komphetho olula wokujikeleza okanye ukufakwa kwesicelo sokwaleka, obu buchwephesha baseJamani bubandakanya ikhemikhali elawulwa kakhulu kunye nonyango lomatshini. Ilungisa ngokuchanekileyo i-micro-geometry yomgca wokusika kwinqanaba le-sub-micron.
ISayensi yokuLawulwa "Ukudukisa":
Indalo eJongene neMicro-Bevel: Endaweni yokushiya umphetho obukhali nge-atom (kunye ne-brittle), inkqubo idala i-bevel engaguqukiyo, i-minuscule okanye i-radius ecaleni komphetho wokusika. Le micro-bevel yenzelwe ukuba ibenkulu ngokwaneleyo ukuphelisa ezona ndawo zibuthathaka, ezona ndawo zinokwaphuka.
Ukuphelisa i-Micro-Defects: Inkqubo ngaxeshanye ilula kwaye isusa izitenxo ze-microscopic kunye namanqaku oxinzelelo ashiywe kwinkqubo yokusila, ukudala indawo yenguqu engenasiphako emva komgca wokusika.
Umda owomeleziweyo weMfezeko: Isiphumo ngumphetho ogcina ubukhali obukhethekileyo bokusika kodwa unamandla anyukileyo kunye nokuxhathisa ukutshiza kunye nokugqabhuka.
Iinzuzo zokuSebenza kwiLizwe lokwenyani:
Lo mda wenziwa ngobunono uguqulela kwiinzuzo ezibonakalayo kumgangatho wevenkile:
"Ubukhali kwaye ukhawuleze" Ukusika: Ngokuchaseneyo ne-intuition, umphetho ogqithisiweyo unamava angaphantsi kokusika. Ngokuthintela i-micro-chipping kunye nokuqaliswa kwe-BUE, isixhobo sigcina ijometri eyiliweyo kunye nobukhali ixesha elide. Oku kuvumela isantya esiphezulu somatshini (Vc) kunye namazinga okutya (f) ngaphandle kokuncama ingqibelelo edge, ukukhulisa ngokuthe ngqo imveliso.
UkuGqibela okuPhakamileyo okuPhezulu: Ukupheliswa kwe-micro-chipping kunye ne-edge eyakhelwe-up ibalulekile ekufezekiseni ukugqitywa komphezulu okhethekileyo. Isenzo esizinzileyo, esigudileyo sokusika sivelisa ama-bores anexabiso eliphantsi ngokuphawulekayo le-Ra, ehlala isusa imisebenzi yokugqiba okwesibini. Ilifa lemveli elithi "inkqubo yobuchwephesha yaseJamani" ligxininisa oku kufunwa kokuchaneka kokugqibela kunye nokugqibelela komphezulu.
Ukunciphisa i-Cutting Tumors (BUE): Ngokulula umgca kunye nokususa amanqaku oxinzelelo, i-passivation inciphisa iindawo ze-nucleation apho izinto zokusebenza zinokubambelela. Idibaniswe nesenzo sokusika esithambileyo kunye nokunciphisa ukungqubuzana, oku kunciphisa kakhulu ukubunjwa kwe-edge eyakhelweyo, iqinisekisa ukuhamba kwe-chip ehambelanayo kunye nemikhosi yokuzinza.
Ubomi Besixhobo Esongeziweyo: Ukomelela komphetho owomeleziweyo kunye nokumelana nokutshiphuzwa kunye neendlela zokunxiba ziguqulela ngokuthe ngqo kubomi besixhobo esisebenzisekayo ixesha elide. Izixhobo zisebenza ngokuqhubekayo kumalungu amaninzi ngaphambi kokuba zifune ukutshintshwa okanye ukulungiswa kwakhona, ukunciphisa ixesha lokuphumla kunye neendleko zezixhobo ngenxalenye nganye.
Ukwenyuka kokuthembeka kweNkqubo: Ukunciphisa ukuchasana kokusika kunye nokunyanzeliswa kwe-BUE kukhokelela kwiimeko ezinokuqikelelwa ngakumbi, ezizinzileyo zomatshini. Oku kunciphisa ukungcangcazela, kuphucula ukuchaneka kobukhulu, kwaye kunciphisa umngcipheko weendawo ezilahliweyo ngenxa yokusilela kwesixhobo okanye umgangatho ombi womphezulu.
Impembelelo yoShishino kunye nokuFumaneka:
Itekhnoloji iluncedo kakhulu ekufuneni izicelo eziqhelekileyo kwi-aerospace, i-automotive powertrain, ukuveliswa kwezixhobo zonyango, kunye necandelo lamandla, apho imingxuma enzulu, echanekileyo kwizinto ezinzima ziyisiqhelo. Abavelisi abazamana nomgangatho wokugqiba, ukungaguquguquki kobomi besixhobo, okanye imiba eyakhiweyo ngabathengi abaphambili abanokuxhamla.
