Ngwaọrụ carbide nwere uru ndị a:
(1) Ihe mkpuchi nke elu oyi akwa nwere oke isi ike ma na-eyi nguzogide. E jiri ya tụnyere carbide a na-adịghị ahụkebe, carbide carbide na-enye ohere iji ọsọ na-egbutu elu, si otú a na-eme ka ọrụ nhazi ya dịkwuo elu na otu ọsọ.
(2) Coffiefs nke esemokwu dị n'etiti ihe ejikọtara na ihe ha haziri ahaziri pere mpe. E jiri ya tụnyere carbide na-adịghị mma, ịkpụ ike nke carbide carbide belatara ka a belata ruo oge ụfọdụ, na usoro a haziri ahazi ka mma.
(3) N'ihi arụmọrụ dị mma zuru oke, mma carbide a na-eji mara mma nwere nke ọma na ngwa ngwa wider. Usoro a na-ejikarịkarị mkpuchi mkpuchi ciment dị elu okpomọkụ (HTCVD). A na-eji ego mkpuchi nke plasma.
Ikike mkpuchi nke ciment carbise culting:
Ihe ndị a na-ahụkarị bụ ticnium nitride (tin), ticn carbonitride (ticn) na Titanium Aluminide (Tiain).
Igwe mkpuchi titanium nwere ike ịbawanye ihe siri ike ma na-eyi nguzogide nke ngwaọrụ, belata ọgbọ nke nsọtụ, wee gbasaa ndụ nke ngwá ọrụ. Ngwa titanium nitride etinyere kwesịrị ekwesị maka ịhazi usoro nchara na igwe anaghị agba nchara.
Elu nke mkpuchi carbonium bụ isi awọ, ihe isi ike dị elu karịa mkpuchi mkpuchi titanium, na ndị na-eyi eguzogide ka mma. E jiri ya tụnyere ihe mkpuchi titanium, enwere ike ịhazi ngwa ngwa tianide, ka enwere ike ịhazi ngwa ngwa na-agba ọsọ na-agba ọsọ (40%), yana ihe mwepụ ihe eji eme ihe dị elu. Titanium carbonide ngwa ngwa nwere ike hazie ụdị ọrụ ọrụ.
Mkpuchi titanium na-awọ bụ isi awọ ma ọ bụ ojii. Ọ na-eyikwasị n'elu ụlọ ọrụ carbide siri ike. A ka nwere ike ịhazi ya mgbe okpomọkụ na-eru 800 ℃. Ọ dị mma maka ịkpụ ngwa ngwa dị elu. N'oge akọrọ, a ga-ewepụ chiiz ndị ahụ na mpaghara mbelata. Titanium Aluminide dị mma maka nhazi nke na-emebi emebi dị ka nke siri ike ígwè, titanium alloy, nke ihe nkedo na-acha uhie uhie na akwa si silicon aluminom alloy.
Ibufe ngwa nke ciment caring cutter:
A na-egosipụtakwa ọganihu nke teknụzụ ibugo ngwaọrụ na ịdị urè nano. A na-akpọkarị ọtụtụ narị akwa nke ihe nwere ọtụtụ ihe dị ọtụtụ nanotube, a na-akpọkarị ihe nano-coita. Ogo nke ihe eji eme ihe nke nano-mkpuchi pere mpe, ya mere ókè ọka dị ogologo, nke nwere ihe isi ike okpomọkụ dị elu. , Ike na mgbaji siri ike.
Ndị na-eme egwuregwu nano-mkpuchi nwere ike iru HV2800 ~ 3000, na ndị na-eyi eguzogide ka mma site na 5% 50% karịa nke micron ihe. Dabere na akụkọ, n'oge dị ugbu a, nke 62 n'ígwé ejikọtara ọnụ na mkpuchi nke titanium carbitride na 400 n'ígwé ngwaọrụ nke Tialn-Tialn / Al2O3 mepụtara.
E jiri ya tụnyere nke siri ike mkpuchi, sulfide (Mos2, ws2) a na-akpọkarị mkpuchi aluminom, nke a na-ejikarị ikpuchi-ike alloys.
Ọ bụrụ na ị nwere mkpa, biko bia kpọtụrụ MSK, anyị siri ike iji nye ngwaọrụ nha na obere oge yana atụmatụ ngwaọrụ ahaziri maka ndị ahịa.
