Qalabka carbide-ka ee dahaarka leh waxay leeyihiin faa'iidooyinka soo socda:
(1) Qalabka dahaadhka ee lakabka dusha sare wuxuu leeyahay adkeysi aad u sarreeya iyo iska caabin xirasho. Marka la barbardhigo carbide-ka sibidhka ee aan dahaarka lahayn, carbide-ka sibidhka ee dahaarka leh wuxuu u oggolaanayaa isticmaalka xawaaraha jarista oo sareeya, taasoo hagaajinaysa hufnaanta farsamaynta, ama Waxay si weyn u kordhin kartaa cimriga qalabka isla xawaaraha jarista.
(2) Isku-dhafka is-dhexgalka u dhexeeya walaxda dahaarka leh iyo walaxda la farsameeyay waa yar yahay. Marka la barbardhigo kartoonka sibidhka ah ee aan dahaarka lahayn, xoogga jarista kartoonka sibidhka ah ee dahaarka leh ayaa hoos u dhacaya ilaa xad, tayada dusha sare ee la farsameeyayna way ka fiican tahay.
(3) Iyada oo ay ugu wacan tahay waxqabadka dhammaystiran ee wanaagsan, mindi carbide-ka dahaarka leh wuxuu leeyahay kala duwanaansho wanaagsan iyo kala duwanaansho ballaaran oo codsi ah. Habka ugu badan ee loo isticmaalo dahaarka carbide-ka ee sibidhka leh waa kaydinta uumiga kiimikada heerkulka sare leh (HTCVD). Kaydinta uumiga kiimikada ee balaasmaha (PCVD) ayaa loo isticmaalaa in lagu dahaadho dusha sare ee carbide-ka sibidhka leh.
Noocyada dahaarka ee jarjarayaasha wax lagu milo ee carbide-ka sibidhka ah:
Saddexda walxood ee ugu badan ee dahaarka leh waa titanium nitride (TiN), titanium carbonitride (TiCN) iyo titanium aluminide (TiAIN).
Dahaarka nitride-ka ee Titanium wuxuu kordhin karaa adkaanta iyo iska caabbinta dusha sare ee qalabka, wuxuu yareyn karaa isku-dhafka is-jiidjiidka, wuxuu yareyn karaa soo saarista geeska la dhisay, wuxuuna dheereyn karaa cimriga qalabka. Qalabka dahaarka leh ee Titanium nitride waxay ku habboon yihiin farsamaynta birta dahaarka yar iyo birta aan daxalka lahayn.
Dusha sare ee dahaarka titanium carbonitride waa cawl, adkaanta ayaa ka sarreysa tan dahaarka titanium nitride, iska caabbinta xirashadana way ka fiican tahay. Marka la barbardhigo dahaarka titanium nitride, qalabka dahaarka titanium carbonitride waxaa lagu farsameyn karaa xawaare quudin oo ka sarreeya iyo xawaare jaritaan (40% iyo 60% ka sarreeya kan dahaarka titanium nitride, siday u kala horreeyaan), heerka ka saarista walxaha shaqadana waa ka sarreeyaa. Qalabka dahaarka leh ee titanium carbonitride wuxuu farsameyn karaa noocyo kala duwan oo agab shaqo ah.
Dahaarka aluminiumka titanium waa cawl ama madow. Inta badan waxaa lagu dahaadhaa dusha sare ee saldhigga qalabka carbide-ka ee sibidhka lagu sameeyay. Wali waa la farsamayn karaa marka heerkulka jarista uu gaaro 800 ℃. Waxay ku habboon tahay jarista qalalan ee xawaaraha sare leh. Inta lagu jiro jarista qalalan, jajabyada ku yaal aagga jarista waxaa laga saari karaa hawo la cadaadiyay. Titanium aluminide wuxuu ku habboon yahay farsamaynta walxaha jilicsan sida birta adag, birta titanium, birta ku salaysan nickel, birta la shubay iyo birta aluminiumka silicon sare leh.
Codsiga dahaarka ee makiinada wax lagu qodo ee carbide-ka sibidhka ah:
Horumarka tignoolajiyada dahaarka qalabka ayaa sidoo kale ka muuqda wax ku oolnimada dahaarka nano. Dahaarka boqolaal lakab oo walxo ah oo leh dhumuc dhowr nanomitir ah oo ku yaal qalabka salka qalabka waxaa loo yaqaan dahaarka nano. Cabbirka walax kasta oo ka mid ah walxaha dahaarka nano waa mid aad u yar, sidaa darteed xadka hadhuudhku aad buu u dheer yahay, kaas oo leh adkeysi heerkul sare oo sarreeya. , Xoog iyo adkeysi jabka.
Adkaanta Vickers ee dahaarka nano waxay gaari kartaa HV2800～3000, iska caabbinta xirashadana waxaa lagu hagaajiyaa 5%～50% marka loo eego walxaha micron. Sida laga soo xigtay warbixinnada, hadda, 62 lakab oo qalab dahaar ah oo leh dahaar beddel ah oo ah titanium carbide iyo titanium carbonitride iyo 400 lakab oo qalab nano ah oo TiAlN-TiAlN/Al2O3 ah ayaa la sameeyay.
Marka la barbardhigo dahaarka adag ee kor ku xusan, sulfide (MoS2, WS2) oo lagu dahaadhay birta xawaaraha sare leh waxaa loo yaqaan dahaarka jilicsan, kaas oo inta badan loo isticmaalo jarista dahaarka aluminiumka xoogga badan, dahaarka titanium iyo biraha naadirka ah qaarkood.
Haddii aad u baahan tahay, fadlan la xiriir MSK, waxaan si gaar ah u rabnaa inaan macaamiisha siino qalab cabbir caadi ah waqti gaaban gudaheed.
