Ukuqhubela phambili kwiSayensi yeMathiriyeli: Uphononongo oluthelekisayo lwe-Titanium Nitride, iChromium Nitride, kunye neTungsten Nitride

Kwinkalo ephuhlayo ngokukhawuleza yenzululwazi yemathiriyeli, ukuphuhlisa nokusebenzisa i-nitride yokwambathisa itshintshe ngokupheleleyo amashishini ukusuka kwi-aerospace ukuya kwimoto. Phakathi kwezi zixhobo, i-titanium nitride (TiN), i-chromium nitride (i-CrN), kunye ne-tungsten nitride (WN) zivelele ngenxa yokusebenza kwazo okugqwesileyo kunye nezicelo ezahlukeneyo.

I-Titanium nitride: umgangatho wegolide

I-Titanium nitride , edla ngokufinyezwa njengeTiN, iye yaba yintsika yengubo ezisebenza kakuhle kwihlabathi liphela. I-TiN yaziwa ngombala wayo wegolide omangalisayo, obonelela ngomxube omangalisayo wobulukhuni, ukumelana nokuguguleka, kunye nomlinganiselo ophantsi wokungqubana. Ezi mpawu ziyenza ifaneleke kwizixhobo zokusika ezigqunyiweyo, iidrili, kunye nezinye iindawo ezenziwe ngomatshini. Ukusebenzisa umgubo we-titanium nitride ekwenzeni izinto kuqinisekisa ukuba ezi zixhobo zihlala zibukhali kwaye zihlala ixesha elide, ziphucula kakhulu ukusebenza kakuhle kwaye zinciphisa ixesha lokungasebenzi.

Ukongeza kwizixhobo, i-TiN isetyenziswa ngokubanzi kwizicelo zonyango ngenxa ye-biocompatibility yayo kunye nokumelana nokubola. Izixhobo zotyando ezigqunywe nge-TiN zisebenza kakuhle kwaye zisebenza ixesha elide, ziqinisekisa ukhuseleko nokuthembeka kotyando olubalulekileyo. Ukongeza, isibheno sobuhle be-TiN siyenza idume kwiingubo zokuhombisa ubucwebe kunye neewotshi, ukudibanisa ukusebenza kunye nobuhle.

I-Chromium nitride: intshatsheli yokonakala

I-Chromium nitride (i-CrN) yabelana ngeepropati ezininzi eziqhelekileyo kunye ne-titanium nitride kodwa ibalasele ngokukodwa kwiindawo apho ukuxhathisa ukubola kubalulekile. I-CrN yokwambathisa ibonelela ngokhukuliseko lwekhemikhali olugqwesileyo kunye nokhuseleko lwe-oxidation, nto leyo iyenza ibaluleke kakhulu kwiindawo ezingqonge iifektri. Ngokomzekelo, imboni yeemoto ixhomekeke kumacandelo e-CrN-coated ukumelana neekhemikhali ezinobundlobongela kunye nokushisa okugqithisileyo ngaphandle kokuchaphazela ukusebenza.

Enye yeenzuzo eziphambili ze-CrN kukukwazi ukusebenza ngokufanelekileyo phantsi kweemeko ezimanzi okanye ezimanzi. Ngokungafaniyo ne-TiN, i-TiN ibonisa ukusebenza okuncitshisiweyo xa ibonakaliswe kumswakama ixesha elide, ngelixa i-CrN igcina ingqibelelo kunye neempawu zokukhusela. Oku kuyenza ibe lolona khetho lukhethwayo kwiinkqubo zehydraulic, izinto zokutofa ngamafutha, kunye nezinye iindawo ezisebenza kwindawo ezonakalisayo. Ukongezelela, i-coefficient ephantsi ye-friction ye-CrN inceda ukunciphisa ukunxiba kunye nokwandisa ubomi benkonzo yezixhobo zoomatshini.

I-tungsten nitride: ubunzima obuphezulu kakhulu kunye nozinzo

I-tungsten nitride (WN) inyuse ubunzima bayo kunye nokuzinza kwe-thermal. I-WN ineyona ndawo iphakamileyo yokunyibilika phakathi kwee-nitrides, iyenza ilungele usetyenziso olufuna ukumelana nobushushu obugqithisileyo. Kwishishini le-aerospace, i-tungsten-coated nitride-coated components inokumelana nobushushu obukhulu obuveliswa ngexesha lokungena kwakhona kwi-atmosfera yoMhlaba, ukuqinisekisa ukusebenza okuthembekileyo phantsi kwezona meko zinzima kakhulu.

Ubunzima obungenakulinganiswa be-WN bukwafanelekile kwizixhobo zokusika ezilukhuni kunye nokubumba. Xa ukuchaneka kunye nokuqina kungenakuxoxisana, abavelisi baphendukela kwi-tungsten nitride, njengokuveliswa kwezixhobo zetsimbi ezikhawulezayo kunye neentsimbi ezinzima. Naphantsi kwemithwalo enzima kunye nesantya esiphezulu, ubukhali bunokugcinwa, okuphucula imveliso kunye nokunciphisa iindleko zokugcina.

Ukongeza, i-WN inokumelana nokunxiba okugqwesileyo kunye nokuqina, okwenza ukuba ibe nexabiso elikhulu kwimigodi kunye nemimandla yokwakha. Izixhobo ezigqunywe nge-tungsten nitride zinokumelana nezinto ezirhabaxa njengesanti kunye negrabile ngaphandle kokuthotywa okubalulekileyo. Oku kunwebeka kuguqulela ekusebenzeni okuphezulu kunye namazinga asezantsi okutshintsha, okonga iindleko ezinkulu ngokuhamba kwexesha.

Ngasinye sezi zixhobo ze-nitride-titanium nitride (TiN), i-chromium nitride (i-CrN), kunye ne-tungsten nitride (WN) -inika iingenelo ezikhethekileyo, ezivumela iinjineli kunye nabavelisi ukuba bakhethe ukhetho olufanelekileyo olusekelwe kwiimfuno ezithile. I-TiN ikhanya kwizicelo ezifuna ukungqubana okuphantsi kunye ne-aesthetics, ngelixa i-CrN isebenza kakuhle kwiindawo ezinobungozi. I-WN ibalasele ngenxa yokuqina kwayo okuphezulu ngokugqithisileyo kunye nokuzinza kwe-thermal, okwenza ukuba ibaluleke kakhulu phantsi kobushushu obuphezulu kunye neemeko zokusila.

Njengoko ishishini liqhubeka nokugqobhoza imida yokusebenza kunye nokusebenza kakuhle, indima yokwaleka kwe-nitride ephucukileyo iya ibaluleke kakhulu. Abavelisi banokufezekisa ukuthembeka okuphezulu kunye nexesha lokuphila kwiimveliso zabo ngokusebenzisa izibonelelo ze-titanium nitride, i-chromium nitride, kunye ne-tungsten nitride. Nokuba kungenxa yokubengezela kwegolide kwe-TiN, ukuxhathisa kokutya kwe-CrN, okanye ukuqina okuphezulu kakhulu kwe-WN, ezi mathiriyeli ziqhuba ukuqamba izinto ezintsha kwisayensi yezixhobo kunye nokumisela imigangatho emitsha.
