Middiyaha Jikada Ruitai: Ilahaaga Premier ee Midiyaha Jikada ee Gaarka ah ee laga sameeyay Shiinaha
daahan Titanium nitride
Tin waa dahaarka guud-ujeeddada pvd, kaas oo hagaajin kara adkaanta qalabka iyo leeyihiin heerkul oksaydhyo sare. daahan ayaa saamayn processing wanaagsan ee mindiyaha birta xawaaraha sare.
Dahaarka Nitrogen-TiC (ticn)
Cunsurka kaarboon ee ku jira daahan tikn waxay wanaajisaa adkaanta qalabka iyo saliidda. Waa dahaar ku habboon qalabka birta xawaaraha sare leh.
Nitrojiin, aluminium iyo daahan titanium (tialn/altin)
Lakabka alumina ee lagu sameeyay dahaadhka nitrogen, aluminium, titanium iyo aluminium ayaa hagaajin kara nolosha qalabka goynta heerkulka sare. Dahaarka loogu talagalay goynta qallalan ama qallalan.Qaybta aluminiumka ilaa titanium ee dahaarka waa ka duwan yahay, iyo daboolka nitrogen-titanium-aluminiumku wuxuu leeyahay qallafsanaan ka sarreeya lakabka nitrogen-aluminium-titanium.
Dahaarka Chromium nitride (CrN)
Iska caabbinta adhesion-ka wanaagsan ee daahan chromium nitride ayaa ka dhigaysa dahaarka la door bidayo ee habaynta burada. Ka dib markii daahan this ku dhowaad aan la arki karin, waxqabadka machining ee qalab goynta sida birta xawaaraha sare iyo carbide sibidhka la hagaajin doonaa.
Dahaarka Dheemanka (Diamond)
Daahan dheemanka ah ayaa ah daaha ugu fiican ee qalabka wax lagu farsameeyo ee birta ah. Waa dahaar ku habboon oo loogu talagalay graphite machining, composites bir ku salaysan (mmc), aluminium aluminium sare silikoon iyo qalabka abrasion sare. keeni fal-celin kiimikaad, si markaas lakabka adhesion ee u dhexeeya daahan iyo qalabka la burburiyo). Dahaarka loo isticmaalo shiididda adag, tuubada iyo qodista way kala duwan yihiin waxaana loo isticmaalaa xaalado gaar ah. Intaa waxaa dheer, waxaa jira lakabyo badan oo lakabyo ah, dhejisyada noocan oo kale ah waxay ku dhexjiraan inta u dhaxaysa lakabka dusha sare iyo qalabka qalabka, taas oo hagaajinaysa nolosha qalabka.
Dahaarka oksidaynta (Homo)
Qalabka waxaa lagu kululeeyaa uumiga biyaha ee 500 ~ 550 oc 30 ~ 60 daqiiqo si loo sameeyo lakabka fe3o4 ee dusha sare ee qalabka, taas oo ah habka daaweynta oksaydhka oo leh dhumucda filimka maqaarka oxide ee kala duwan ee 1 ~ 3μ. Sababtoo ah dabeecadeeda daloola, filimku wuxuu hayn karaa saliidda goynta wuxuuna yarayn karaa kulaylka. Aad bay waxtar ugu leedahay qalabka goynta adag, birta cufan ee sarreeya, birta aan fiicnayn iyo birta shubka ah.
