Mumakore achangopfuura, PCD yekucheka maturusi ave achiwedzera kushandiswa mumaindasitiri ekugadzirisa ealuminium, aluminium alloys, mhangura, uye zvimwe zvisiri zvesimbi.
Ndeapi mabhenefiti ePCD ekucheka maturusi mualuminium kugadzirisa uye nzira yekusarudza yakakodzera PCD yekucheka maturusi?
ChiiPCD yekucheka zvishandiso?
PCD yekucheka maturusi kazhinji anoreva polycrystalline diamond maturusi.Iyo PCD inoumbwa shizha rinoshandiswa rinosiirwa kubva kune yakasikwa kana yekugadzira yakagadzirwa nedhaimani poda uye mabhinda (ane simbi senge cobalt uye nickel) mune imwe chikamu pakupisa kwepamusoro (1000-2000 ℃) uye yakanyanya kudzvanywa (50000 kusvika 100000 atmospheres).Haisi chete ine kuomarara kwakanyanya uye kupfeka kuramba kwePCD, asi zvakare ine simba rakanaka uye kuoma kwecarbide.
Mushure mekugadzirwa kuita chishandiso chekucheka, ine hunhu hwekuoma kwakanyanya, yakakwira yekupisa conductivity, yakaderera thermal yekuwedzera coefficient, yakakwira elastic modulus, uye yakaderera friction coefficient.
OPT yekucheka maturusi ndeye yepamusoro-mhando PCD yekuisa mutengesi, Isu tinokutsigira mukutenga kwezvako zvepagore zvaunoda pamitengo yemakwikwi, ichipa mhando yepamusoro uye yakazara yakazara masevhisi.
Zvakanakira zvePCD isa mualuminium kugadzirisa
(1) Kuoma kwePCD maturusi anogona kusvika 8000HV (80-120 nguva iyo yecarbides)
uye kuramba kwavo kupfeka kwakanaka kwazvo.
(2) Thermal conductivity yePCD zvishandiso ndeye 700W/MK (1.5-9 nguva iyo yecarbides), iyo inowedzera zvakanyanya hupenyu hwechishandiso nekuda kwekuita kwayo kupisa kwekushisa.
(3) Iko friction coefficient yePCD maturusi kazhinji ingori 0.1 kusvika 0.3, yakaderera zvakanyanya pane iyo yecarbides, iyo inogona kuderedza zvakanyanya kutema simba uye kuwedzera hupenyu hwematurusi.
(4) Zvishandiso zvePCD zvine diki coefficient yekuwedzera kwekupisa, diki deformation yekupisa, yakakwirira machining kurongeka uye yakakwirira workpiece pamusoro pemhando.
(5) Nzvimbo yePCD yekucheka maturusi ane hukama hwakaderera nezvinhu zvisiri-ferrous uye zvisiri zvesimbi, saka hazvisi nyore kugadzira chip buildup.
(6) Zvishandiso zvePCD zvine yakakwira elastic modulus uye hazvitani kuputsika.Iyo yakasviba radius yekucheka kwekucheka inogona kunge yakadzika diki, iyo inogona kuchengetedza kupinza kwekucheka kwekucheka kwenguva yakareba.
Kubva pane zvakanakira zviri pamusoro, maturusi ePCD anogona kugadzira aluminium alloy zvinhu nekumhanya kwakanyanya, nehupenyu hwekushandisa hwezviuru zvakati kusvika makumi ezviuru zvezvidimbu.Kunyanya akakodzera kugadzirwa kwakawanda kweakakwira-kumhanya uye akakwira-vhoriyamu yekucheka (3C dhijitari, indasitiri yemotokari, munda wemuchadenga), sekugadzirisa magomba echigadzirwa chedhijitari, mapistoni emotokari, mavhiri emotokari, mhete dzemaroller, nezvimwe.
Ungasarudza sei PCD yekucheka zvishandiso?
Kazhinji kutaura, iyo yakakura kukura kwechikamu chePCD, ndiko kusimba kwekupfeka kwechishandiso.
Kazhinji, yakanaka particle PCD inoshandiswa kuita chaiyo kana yekupedzisira machining, nepo coarse particle PCD maturusi anoshandiswa kuita hutsinye machining.
Vagadziri vezvishandiso vanowanzokurudzira kushandisa magiredhi ePCD akatsetseka kuti agadzirise silicon isina uye yakaderera silicon aruminiyamu alloy zvinhu, uye kushandisa coarse-grained PCD mamakisi kugadzira yakakwira silicon aluminium alloy zvinhu, nechikonzero chimwe chete.
Hunhu hwepamusoro hwakagadziriswa nePCD zvishandiso kwete chete hunoenderana nehukuru hwechishandiso, asiwo pamhando yemupendero wechishandiso, saka kunaka kwePCD zvishandiso kunofanirwa kunge kuri nani.
Pane kazhinji nzira mbiri dzakajairwa dzekugadzirisa PCD mipendero yezvishandiso, imwe iri kuburikidza nekunonoka kucheka waya.Iyi nzira ine mari shoma yekugadzirisa, asi hutano hwemapendero huri pakati.Imwe nzira inowanikwa kuburikidza nelaser processing, iyo ine mutengo wakakwira zvishoma, asi mhando yekucheka yakakwira zvakanyanya (kune zvakare nzira yekutanga laser rough machining uyezve kugaya chaiko machining, ayo ane mhando iri nani yekucheka. kumucheto).Zvichiri kudiwa kubhadhara zvakanyanya pakusarudza.
Kutaura zvazviri, ndizvo chete.Mamwe mamwe akanyanya kutsanangurwa, anosanganisira mutengo uye kucheka ma paramita, zvakare anofanirwa kutarisa kune chaiwo chigadzirwa paramita inopihwa nevagadziri vakasiyana.Zvakare, mukuwedzera kune zvine musoro kusarudzwa kwechishandiso geometry uye kucheka paramita, aluminium kugadzirisa dzimwe nguva kunoda vatengesi vezvishandiso kuti vape mhinduro kumatambudziko anosanganikwa nawo panguva yekushandisa maturusi.
