Ulenza njani uFakelo lokuJika?

Ukufakelwa kwezinto eziguqukayo zizixhobo zokusika ezisebenzayo ezisetyenziselwa ukwenza intsimbi, insimbi engenasici, kunye nezinye izinto. Ukuguqula ukufakwa kunokumelana nokushisa okulungileyo kunye nokuxhatshazwa kokugqoka, ngoko kubonakala ngokubanzi kwizixhobo ezininzi zokusika kunye noomatshini. Phantse ukuguqula ukufakwa kwenziwa ngezinto ezinzima kunazo zonke emhlabeni, i-tungsten carbide. Kule nqaku, inkqubo yokuvelisa ukuguqula ukufakwa kuya kuqaliswa.

Xuba i-tungsten carbide powder kunye ne-binder powder. Ukwenza into ejikajikayo, umzi-mveliso wethu uya kuthenga i-100% yemathiriyeli ekrwada ye-tungsten carbide powder kwaye wongeze umgubo wecobalt kuyo. Izibophelelo ziya kubopha iincinci ze-tungsten carbide kunye. Zonke izinto ezisetyenziswa ekrwada, kubandakanywa i-tungsten carbide powder, i-binder powder, kunye nezinye izithako, zithengwa kubaboneleli. Kwaye izinto eziluhlaza ziya kuvavanywa ngokungqongqo kwilebhu.

Ukugaya kusoloko kwenzeka kumatshini wokungqusha webhola onolwelo olunjengamanzi kunye ne-ethanol. Inkqubo iya kuthatha ixesha elide ukufikelela kwisayizi ethile yeenkozo.

I-slurry egayiweyo iya kugalelwa kwisitshizi sokutshiza. Iigesi ezingasebenziyo njengenitrogen kunye nobushushu obuphezulu ziya kongezwa ukwenza ulwelo lube ngumphunga. Iipowders, emva kokutshiza, ziya kuba zome, eziza kuzuza ngokucinezela kunye ne-sintering.

Ngexesha lokucinezela, i-tungsten carbide turning inserts iya kuxilwaniswa ngokuzenzekelayo. Izixhobo ezijikayo ezicinezelweyo zibuthathaka kwaye kulula ukuziqhekeza. Ngoko ke, kufuneka bafakwe kwiziko elitshisayo. Ubushushu be-sintering buyakuba malunga ne-1,500°C.

Emva kokucoca, ukufakwa kufuneka kube phantsi ukuze kufezekiswe ubungakanani babo, ijometri, kunye nokunyamezela. Uninzi lwezinto ezifakelwayo ziya kugqunywa ngekhemikhali yokubeka umphunga, i-CVD, okanye ukubekwa komphunga obonakalayo, iPVD. Indlela ye-CVD kukuba nekhemikhali yokusabela kumphezulu wokufaka izinto ezijikajikayo ukwenza ukufakwa komelele kwaye kube nzima. Kwinkqubo ye-PVD, i-tungsten carbide i-turning inserts iya kufakwa kwiindawo zokulungisa, kwaye izinto zokugubungela ziya kunyuka phezu kwendawo yokufaka.

Ngoku, ukufakwa kwe-tungsten carbide kuya kujongwa kwakhona kwaye emva koko kupakishwe ukuthumela kubathengi.

Ukuba unomdla kwi-tungsten carbide ukuguqula ukufakwa kwaye ufuna ulwazi oluthe kratya kunye neenkcukacha, ungaQHAGAMSHELANA NATHI ngefowuni okanye ngeposi ekhohlo, okanye SITHUMELE MAIL emazantsi ephepha.
