Ngwaọrụ carbide a kpụchara akpụ nwere uru ndị a:
(1) Ihe mkpuchi nke oyi akwa elu nwere oke ike na iguzogide iyi. Ma e jiri ya tụnyere carbide simenti a na-ekpuchighị ekpuchi, carbide simenti a kpuchiri ekpuchi na-enye ohere iji ọsọ ịkpụcha dị elu, si otú a na-eme ka arụmọrụ nhazi dịkwuo mma, ma ọ bụ Ọ nwere ike ime ka ndụ ngwaọrụ dịkwuo elu n'otu ọsọ ịkpụcha.
(2) Oke esemokwu dị n'etiti ihe e ji kpuchie ihe na ihe e ji emepụta ihe dị obere. Ma e jiri ya tụnyere carbide simenti a na-ekpuchighị ekpuchi, ike ịkpụ nke carbide simenti a kpuchiri ekpuchi na-ebelata ruo n'ókè ụfọdụ, mma elu a na-ahazikwa ka mma.
(3) N'ihi ezigbo arụmọrụ zuru oke, mma carbide a kpuchiri ekpuchi nwere ọtụtụ ihe dị iche iche na oke ojiji sara mbara. Ụzọ a na-ejikarị eme mkpuchi carbide a kpụkọrọ akpụkọ bụ ebe a na-etinye vapor kemịkalụ dị elu (HTCVD). A na-eji plasma kpụkọọ vapor kemịkalụ (PCVD) iji kpuchie elu carbide a kpụkọrọ akpụkọ.
Ụdị mkpuchi nke ihe e ji egweri ígwè simenti:
Ihe mkpuchi atọ a na-ejikarị eme ihe bụ titanium nitride (TiN), titanium carbonitride (TiCN) na titanium aluminide (TiAIN).
Mkpuchi Titanium nitride nwere ike ime ka ike na ike nke elu ngwaọrụ dịkwuo elu, belata oke esemokwu, belata mmepụta nke ọnụ ọnụ wuru, ma mee ka ndụ ngwaọrụ ahụ dịkwuo ogologo. Ngwaọrụ mkpuchi Titanium nitride dị mma maka nhazi ígwè na-adịghị agba nchara na ígwè anaghị agba nchara.
Elu mkpuchi titanium carbonitride bụ isi awọ, ike ya dị elu karịa nke mkpuchi titanium nitride, ike iyi ya ka mma. Ma e jiri ya tụnyere mkpuchi titanium nitride, enwere ike ịhazi ngwa mkpuchi titanium carbonitride na ọsọ nri na ọsọ mbelata (40% na 60% dị elu karịa nke mkpuchi titanium nitride, n'otu n'otu), ọnụego mwepụ ihe eji arụ ọrụ dịkwa elu. Ngwaọrụ mkpuchi titanium carbonitride nwere ike ịhazi ọtụtụ ihe eji arụ ọrụ.
Mkpuchi titanium aluminide bụ isi awọ ma ọ bụ oji. A na-ekpuchi ya nke ọma n'elu ntọala ngwaọrụ carbide e ji simenti mee. A ka nwere ike ịhazi ya mgbe okpomọkụ ịkpụcha ruru 800 ℃. Ọ dị mma maka ịkpụcha nkụ ngwa ngwa. N'oge ịkpụcha nkụ, enwere ike iwepụ ibe ndị dị na ebe ịkpụcha ya site na iji ikuku emechiri emechi. Titanium aluminide dị mma maka nhazi ihe ndị na-agbawa agbawa dịka ígwè siri ike, titanium alloy, nickel-based alloy, cast iron na silicon aluminum alloy dị elu.
Ngwa mkpuchi nke igwe eji egwe ihe carbide eme ihe:
Ọganihu nke teknụzụ mkpuchi ngwaọrụ na-egosipụtakwa n'otú e si eji nano-coating eme ihe. A na-akpọ mkpuchi nano-coating. Nha nke ihe mkpuchi nano ọ bụla dị obere, yabụ ókèala ọka dị ogologo nke ukwuu, nke nwere oke ike okpomọkụ dị elu. , Ike na ike mgbawa.
Ike Vickers nke mkpuchi nano nwere ike iru HV2800～3000, a na-emekwa ka iguzogide iyi dịkwuo mma site na 5%～50% karịa nke ihe micron. Dịka akụkọ si kwuo, ugbu a, emepụtala akwa 62 nke ngwaọrụ mkpuchi nwere mkpuchi ọzọ nke titanium carbide na titanium carbonitride na akwa 400 nke ngwaọrụ mkpuchi nano TiAlN-TiAlN/Al2O3.
Ma e jiri ya tụnyere ihe mkpuchi siri ike dị n'elu, a na-akpọ sulfide (MoS2, WS2) nke e ji ígwè dị elu kpuchie ka ihe mkpuchi dị nro, nke a na-ejikarị eme ihe maka ịkpụ ihe mkpuchi aluminom siri ike, ihe mkpuchi titanium na ụfọdụ ọla ndị dị ụkọ.
Ọ bụrụ na ịchọrọ, biko kpọtụrụ MSK, anyị na-enye ngwaọrụ nha ọkọlọtọ n'oge dị mkpirikpi ma na-eme atụmatụ ngwaọrụ ahaziri maka ndị ahịa.
