Eminyakeni yamuva nje, amathuluzi okusika i-PCD asetshenziswa kakhulu ezimbonini zokucubungula i-aluminium, ama-alloys e-aluminium, ithusi, nezinye izinto ezingezona ezensimbi.
Yiziphi izinzuzo zamathuluzi okusika e-PCD ekucubunguleni i-aluminium nokuthi ungakhetha kanjani amathuluzi wokusika we-PCD afanelekile?
Yini iziAmathuluzi wokusika we-PCD?
Amathuluzi okusika e-PCD ngokuvamile abhekisela kumathuluzi edayimane e-polycrystalline.Ishidi eliyinhlanganisela ye-PCD elisetshenzisiwe lifakwa ku-sintered kusuka kumpushana wedayimane wemvelo noma owenziwe ngokwenziwa kanye nezibophezelo (eziqukethe izinsimbi ezifana ne-cobalt ne-nickel) ngengxenye ethile ekushiseni okuphezulu (1000-2000 ℃) kanye nokucindezela okuphezulu (50000 kuya ku-100000 emkhathini).Ayigcini nje ngokuba nokuqina okuphezulu nokumelana nokugqoka kwe-PCD, kodwa futhi inamandla amahle kanye nokuqina kwe-carbide.
Ngemva kokucubungula ithuluzi lokusika, linezici zobulukhuni obuphezulu, ukuqhutshwa kokushisa okuphezulu, i-coefficient ephansi yokwandisa ukushisa okushisayo, i-modulus ephezulu yokunwebeka, kanye ne-coefficient ephansi ye-friction.
Amathuluzi okusika e-OPT ungumphakeli wokufaka we-PCD wekhwalithi ephezulu, Siyakusekela ekuthengeni izidingo zakho zonyaka ngamanani ancintisanayo, sikunikeza ikhwalithi ephezulu kanye nohlu olubanzi lwezinsizakalo.
Izinzuzo zokufakwa kwe-PCD ekucubunguleni i-aluminium
(1) Ubulukhuni bamathuluzi e-PCD bungafinyelela ku-8000HV (izikhathi ezingama-80-120 zama-carbides)
futhi ukumelana kwabo kokugqoka kuhle kakhulu.
(2) I-thermal conductivity yamathuluzi e-PCD yi-700W/MK (izikhathi ezingu-1.5-9 kune-carbides), eyandisa kakhulu impilo yamathuluzi ngenxa yokusebenza kwayo okuhle kakhulu kokudlulisa ukushisa.
(3) I-coefficient ye-friction yamathuluzi e-PCD ngokuvamile i-0.1 kuya ku-0.3 kuphela, iphansi kakhulu kune-carbides, enganciphisa kakhulu amandla okusika futhi andise impilo yamathuluzi.
(4) Amathuluzi e-PCD ane-coefficient encane yokwandisa okushisayo, ukuguqulwa okuncane kokushisa, ukunemba okuphezulu kwemishini kanye nekhwalithi ephezulu yendawo yokusebenza.
(5) Ingaphezulu lamathuluzi okusika e-PCD linobudlelwane obuphansi nezinto ezingezona ezoni kanye nezingezona ezensimbi, ngakho akulula ukukhiqiza i-chip buildup.
(6) Amathuluzi e-PCD ane-modulus ephezulu yokunwebeka futhi awajwayele ukuphuka.I-radius eyi-blunt enqenqemeni yokusika ingaba yincane kakhulu, engagcina ubukhali bonqenqema lokusika isikhathi eside.
Ngokusekelwe kulezi zinzuzo ezingenhla, amathuluzi e-PCD angakwazi ukucubungula izinto ze-aluminium alloy ngesivinini esikhulu kakhulu, ngokuphila kwethuluzi lezinkulungwane ezimbalwa kuya kwezingamashumi ezinkulungwane zezingcezu.Ikakhulukazi ifaneleka ekukhiqizweni ngobuningi bokusika kwejubane eliphezulu kanye nevolumu ephezulu (idijithali ye-3C, imboni yezimoto, inkambu ye-aerospace), njengokucubungula amagobolondo omkhiqizo wedijithali, ama-piston ezimoto, amasondo ezimoto, ama-roller rings, njll.
Indlela yokukhetha Amathuluzi wokusika we-PCD?
Ngokuvamile, ubukhulu bezinhlayiyana ze-PCD bukhulu, kuqina ukumelana nokugqokwa kwethuluzi.
Imvamisa, i-PCD yezinhlayiyana ezinhle isetshenziselwa ukunemba noma ukunemba okuphezulu, kuyilapho amathuluzi e-PCD ezinhlayiyana ezimahhadla asetshenziselwa ukukhanda amakhanda.
Abakhiqizi bamathuluzi bavame ukutusa ukusebenzisa amamaki e-PCD ahlanjululwe kahle ukuze kucutshungulwe izinto ze-silicon aluminium alloy alloy yamahhala futhi ephansi, nokusebenzisa amamaki e-PCD ama-coarse-grained ukucubungula izinto eziphezulu ze-silicon aluminium alloy, ngesizathu esifanayo.
Ikhwalithi yendawo ecutshungulwe ngamathuluzi e-PCD ayincikile kuphela kusayizi wezinhlayiyana zethuluzi, kodwa futhi nekhwalithi yonqenqema lwamathuluzi, ngakho ikhwalithi yamathuluzi e-PCD kufanele ibe ngcono.
Ngokuvamile kunezindlela ezimbili ezivamile zokucubungula zemiphetho yamathuluzi e-PCD, eyodwa iwukusika izintambo ezihamba kancane.Le ndlela inezindleko eziphansi zokucubungula, kodwa izinga lamaphethelo liyisilinganiso.Enye indlela itholakala ngokucutshungulwa kwe-laser, enezindleko ezithe xaxa, kodwa izinga lokusika liphakeme kakhulu (kukhona nendlela yokuqala yomshini we-laser rough bese ugaya ukunemba kwemishini, enekhwalithi engcono yokusika. unqenqema).Kusadingeka ukuthi unake kakhulu lapho ukhetha.
Uma sikhuluma nje, yilokho kuphela.Eminye imininingwane ecacile, ehlanganisa izindleko kanye nemingcele yokusika, nayo idinga ukubhekisela kumingcele ethile yomkhiqizo ehlinzekwa abakhiqizi abahlukahlukene.Ngaphezu kwalokho, ngaphezu kokukhethwa okunengqondo kwejiyomethri yamathuluzi kanye nemingcele yokusika, ukucubungula i-aluminium ngezinye izikhathi kudinga abahlinzeki bamathuluzi ukuthi banikeze izixazululo zezinkinga okuhlangatshezwana nazo ngesikhathi sokusetshenziswa kwamathuluzi.
