Kusanthula kwa Makhalidwe Ogwira Ntchito Pazida Zisanu Zodula Kwambiri

Superhard chida chuma amatanthauza zinthu zolimba kwambiri zomwe zingagwiritsidwe ntchito ngati chida chodulira. Pakali pano, zikhoza kugawidwa m'magulu awiri: zida zamtengo wapatali za diamondi ndi zida za kiyubiki za boron nitride. Pali mitundu isanu yayikulu yazinthu zatsopano zomwe zagwiritsidwa ntchito kapena zomwe zikuyesedwa

(1) Zachilengedwe komanso zopangapanga zazikulu za diamondi imodzi

(2) Poly diamondi (PCD) ndi poly diamondi composite tsamba (PDC)

(3) CVD diamondi

(4) Polycrystal kiyubiki boron ammonia; (PCBN)

(5) CVD cubic boron ammonia zokutira

1, chilengedwe ndi kupanga lalikulu single crystal diamondi

Natural diamondi ndi yunifolomu kristalo dongosolo popanda m'malire tirigu mkati, kotero kuti m'mphepete chida akhoza theoretically kufika kusalala atomiki ndi sharpness, ndi amphamvu kudula luso, mwatsatanetsatane mkulu ndi ang'onoang'ono kudula mphamvu. The kuuma, kuvala kukana ndi dzimbiri kukana ndi kukhazikika mankhwala a diamondi zachilengedwe kuonetsetsa moyo wautali wa chida, akhoza kuonetsetsa kudula yachibadwa yaitali, ndi kuchepetsa zotsatira za kuvala chida pa kulondola kwa mbali kukonzedwa, madutsidwe ake mkulu matenthedwe akhoza kuchepetsa kutentha kudula ndi mapindikidwe matenthedwe a mbali. Makhalidwe abwino achilengedwe chachikulu cha diamondi ya kristalo amatha kukwaniritsa zofunikira zambiri komanso kudula kopitilira muyeso kwa zida za zida. Ngakhale mtengo wake ndi okwera mtengo, akadali anazindikira ngati mwatsatanetsatane mwatsatanetsatane ndi kopitilira muyeso mwatsatanetsatane zida zipangizo, akhoza ankagwiritsa ntchito pokonza reactors nyukiliya ndi luso zina mkulu m'munda wa magalasi, mizinga ndi miyala, kompyuta zolimba litayamba gawo lapansi, accelerator elekitironi mfuti wapamwamba mwatsatanetsatane Machining, ndi mbali chikhalidwe Kuwonjezera wotchi, zodzikongoletsera, zolembera, phukusi zitsulo zokongoletsera mwatsatanetsatane processing, ophtha ubongo ntchito kupanga, etc. scalpel, masamba owonda kwambiri achilengedwe ndi zida zina zamankhwala. Chitukuko chamakono cha kutentha kwakukulu ndi teknoloji yothamanga kwambiri imapangitsa kuti zitheke kukonzekera diamondi imodzi yaikulu ya kristalo ndi kukula kwake. Ubwino wa chida ichi cha diamondi ndi kukula kwake, mawonekedwe ake ndi kusinthasintha kwake, zomwe sizimatheka muzinthu zachilengedwe za diamondi. Chifukwa cha kusowa kwa kukula kwakukulu kwa diamondi yachilengedwe, mtengo wokwera mtengo, chopangira chachikulu chamtundu umodzi wa kristalo wa diamondi pakukonza kopitilira muyeso ngati choloweza mmalo cha diamondi chachilengedwe chimodzi, kugwiritsa ntchito kwake kudzapangidwa mwachangu.

2, polycrystal diamondi (PCD) ndi polycrystal diamondi composite tsamba (PDC) poyerekeza ndi diamondi lalikulu limodzi galasi diamondi monga chida cha polycrystal diamondi (PCD) ndi polycrystal diamondi gulu gulu (PDC) ali ndi ubwino zotsatirazi: (1) njere chisokonezo dongosolo, isotropic, palibe cleavage pamwamba. Chifukwa chake, sizili ngati diamondi yayikulu imodzi yokhayokha pamphamvu zosiyanasiyana za kristalo, kuuma

Ndipo kukana kuvala kumakhala kosiyana kwambiri, ndipo chifukwa cha kukhalapo kwa cleavage pamwamba ndi brittle.

(2) ali ndi mphamvu mkulu, makamaka PDC chida chuma chifukwa thandizo la masanjidwewo carbide ndipo ali ndi kukana mkulu zimakhudza, mmene zimangotulutsa yaing'ono njere wosweka, osati ngati galasi limodzi diamondi lalikulu kugwa, motero ndi PCD kapena PDC chida osati angagwiritsidwe ntchito mwatsatanetsatane kudula ndi wamba theka mwatsatanetsatane Machining. Komanso angagwiritsidwe ntchito ngati kuchuluka kwa makulidwe akhakula ndi processing wapakatikati (monga mphero, etc.), amene kwambiri amawonjezera ntchito zosiyanasiyana zida diamondi zida.

(3) Chida chachikulu cha PDC chopanda kanthu chikhoza kukonzedwa kuti chikwaniritse zofunikira za zida zazikulu zamakina monga chodulira mphero.

(4) Mawonekedwe enieni amatha kupangidwa kuti akwaniritse zosowa zamitundu yosiyanasiyana. Chifukwa cha kusintha kwa PDC chida billet ndi processing luso monga spark magetsi, laser kudula luso, makona atatu, herringbone, gables ndi zina zapadera zoboola pakati tsamba billet akhoza kukonzedwa ndi kupangidwa. Kuti akwaniritse zosowa za zida zapadera zodulira, zitha kupangidwanso ngati zokutira, masangweji ndi mpukutu wa chida cha PDC.

(5) Magwiridwe azinthu amatha kupangidwa kapena kuneneratu, ndipo chinthucho chimapatsidwa mawonekedwe ofunikira kuti agwirizane ndi momwe amagwiritsidwira ntchito. Mwachitsanzo, kusankha zida za zida za PDC zokongoletsedwa bwino kumatha kupititsa patsogolo mtundu wa chida; Zida za PDC za coarse-grained zitha kupititsa patsogolo kulimba kwa chidacho.

Pomaliza, ndi chitukuko cha zipangizo PCD ndi PDC chida, ntchito PCD ndi PDC chida wakhala kukodzedwa mofulumira kwa kupanga ambiri.

Makampani chimagwiritsidwa ntchito zitsulo sanali achitsulo (zotayidwa, zotayidwa aloyi, mkuwa, mkuwa aloyi, magnesium aloyi, nthaka aloyi, etc.), carbide, ziwiya zadothi, zinthu sanali zitsulo (pulasitiki, mphira zolimba, ndodo mpweya, nkhuni, mankhwala simenti, etc.), gulu zipangizo (monga zitsulo zopangidwa ndi zitsulo zopangidwa ndi CF, CF, zitsulo zopangidwa ndi zitsulo zopangidwa ndi CF, makamaka zitsulo zopangidwa ndi zitsulo zopangidwa ndi CF, zitsulo zopangidwa ndi zitsulo zopangidwa ndi CF, zitsulo zopangidwa ndi pulasitiki, zitsulo zopangidwa ndi pulasitiki, zitsulo zopangidwa ndi pulasitiki, zitsulo zamtengo wapatali, pulasitiki, pulasitiki, pulasitiki, pulasitiki, pulasitiki, pulasitiki, ndi zina zotero. magalimoto ndi matabwa processing makampani, wakhala mkulu ntchito zina miyambo carbide.
