Titanium nitride (TiN) yog ib qho ntawm cov txheej txheem siv ntau tshaj plaws hauv kev lag luam rau ntau xyoo lawm, tab sis raws li kev lag luam tsim thiab xav tau txuas ntxiv hloov, raws li cov kws tshaj lij kev tsim khoom muab ib qho - nres CNC machining thiab txheej txheej, peb tau pom tias muaj kev nyiam ntau ntxiv rau CrN hauv daim ntawv thov ntsib corrosion, adhesion, thiab kub siab.
Yog li, dab tsi yog chromium nitride txheej? Vim li cas nws thiaj li tsim nyog rau koj qhov project tshwj xeeb tshaj li titanium nitride? Hauv tsab xov xwm no, Hansheng coj koj los tshawb txog cov hauv paus ntsiab lus, qhov zoo, thiab kev siv ntawm no nyiaj grey PVD txheej.
CrN Txheej yog dab tsi?
Chromium nitride txheej (tseem hu ua CrN txheej) yog txheej txheej hlau uas siv lub cev vapor deposition (PVD) thev naus laus zis. Tsis zoo li cov txheej txheem ntub dej electroplating xws li chrome plating, CrN txheej txheej txheem yog nqa tawm hauv qhov chaw nqus tsev siab. Thaum lub sij hawm tus txheej txheem no, chromium ions yog evaporated thiab react nrog nitrogen gas los tsim ib tug nyias nyias zaj duab xis nyob rau saum npoo ntawm substrate.
Los ntawm cov tsos, CrN txheej muaj cov yam ntxwv tshwj xeeb. Nws tsis zoo li tooj dag lossis kub zoo li titanium nitride (TiN), tab sis nws yog xim hlau nyiaj lossis nyiaj grey. Qhov no ua rau nws muaj txiaj ntsig zoo dua qub hauv kev siv xws li cov cuab yeej kho mob lossis cov khoom siv ua zaub mov uas xav tau "huv" zoo li xim hlau.
Los ntawm qhov kev xav ntawm microscopic, siab - zoo chromium nitride coatings muaj ib tug finer grain qauv thiab tsawg dua columnar qauv piv rau lwm yam PVD txheej. Cov qauv tshwj xeeb no ua rau CrN txheej nrog cov yam ntxwv tseem ceeb: zoo heev toughness thiab siab hardness zoo kawg nkaus ua ke.
Peb qhov zoo tshaj plaws ntawm CrN txheej
Superior Anti-Galling (Qhov "Tsis yog-Stick" Effect)
Galling, lossis txias vuam, yog npau suav phem hauv kev tsim khoom. Nws tshwm sim thaum ob lub zawv zawg hlau ua ke rau ib leeg, rhuav tshem ntawm qhov chaw.
CrN txheej yog dav lees paub tias yog qhov zoo tshaj plaws PVD tov rau kev tiv thaiv-galling. Nws tsim cov chemically inert barrier nrog ib tug tsawg coefficient ntawm kev sib txhuam (~ 0.5). Qhov no yog qhov tseem ceeb thaum koj cov khoom CNC yog ua los ntawm - lossis cuam tshuam nrog - cov ntaub ntawv nplaum xws li Aluminium, Tooj, lossis Titanium.
Yog tias koj ua cov hlau mos no, cov txheej txheem TiN txheej yuav ua rau cov khoom tsim- rau ntawm ntug txiav. Nyob rau hauv sib piv, CrN txheej tseem huv si, kom ntseeg tau ib tug du tiav thiab ntev lub neej cuab yeej.

Exceptional Corrosion Resistance
Qhov no yog kab tias qhov sib txawv loj tshaj plaws. Thaum TiN muaj qee qhov kev tiv thaiv, nws muaj cov qauv ntxeem tau uas tuaj yeem tso cai rau cov ntsiab lus corrosive kom ncav cuag lub substrate nws thiaj li.
Chromium Nitride txheej, txawm li cas los xij, ua kom muaj kev sib tw, muaj kev cuam tshuam ntau ntxiv. Nws dhau qhov kev ntsuam xyuas cov tshuaj tsuag ntsev kom nruj qhov twg lwm cov txheej txheem ua tsis tiav. Rau cov khoom siv nyob rau hauv marine ib puag ncig, tshuaj ua cov twj tso kua mis, los yog yas pwm tso kua qaub gases (xws li PVC), CrN txheej yog lub undisputed champion.
High Toughness thiab Ductility
Hardness tsis yog txhua yam. Yog tias txheej txheej nyuaj dhau, nws dhau los ua nkig. Nyob rau hauv kev cuam tshuam hnyav, lub nkig txheej tuaj yeem nti lossis flake tawm (delamination).
CrN txheej ua kom muaj qhov sib npaug zoo meej. Nrog lub hardness ntau ntawm 1,750-2,100 HV, nws yog ib qho nyuaj tshaj li cov hlau tab sis khaws cov toughness ntau dua (ductility) dua TiN los yog TiAlN. Qhov no txhais tau tias Chromium Nitride txheej tuaj yeem tiv taus cov khoom hnyav uas muaj nyob hauv cov hlau ua tuag yam tsis muaj kev tawg.
TiN vs. CrN Txheej: Yam Koj Yuav Tsum Xaiv?
Nov yog cov lus nug ntau tshaj plaws uas peb pab pawg engineering tau txais. Txhawm rau pab koj txiav txim siab, cia peb ncaj qha piv TiN vs. CrN txheej.
Qhov tsos:TiN yog kub; CrN txheej yog Silver -Grey.
Hardness:TiN yog ib qho nyuaj me ntsis (~ 2300 HV) dua li CrN (~ 1750 HV).
Kev nplaum:CrN txheej yog qhov zoo tshaj ntawm kev tiv thaiv adhesion (sticking) dua li TiN.
Kub:Chromium Nitride txheej yog ruaj khov mus txog 700 degree, thaum TiN pib oxidize nyob ib ncig ntawm 500 degree.
Corrosion:CrN yeej ob txhais tes.
Kev Txiav Txim
Yog hais tias koj xav tau ib tug dav - lub hom phiaj txheej rau txiav hlau, TiN yog zoo. Txawm li cas los xij, yog tias koj qhov chaw ntsib corrosion, kub kub, lossis kev sib txhuam nplaum, CrN txheej yog qhov kev xaiv zoo tshaj plaws.
Cov ntawv thov tseem ceeb rau Chromium Nitride Txheej
Yas Txhaj & Tuag Casting Pwm
Pwm core kho nrog CrN txheej tso cai rau cov yas kom eject smoothly, txo lub sij hawm voj voog. Tsis tas li ntawd, nws tiv thaiv cov pwm kim hlau los ntawm corrosion los ntawm gassing plastics.
Kev kho mob & Khoom noj khoom haus ua
Cov xim nyiaj ntawm CrN txheej zoo li polished stainless hlau, uas yog nyiam nyob rau hauv kev kho mob teb. Thiab Chromium Nitride txheej yog tshuaj inert thiab biocompatible. Nws tiv taus rov ua kom tsis muaj menyuam thiab cov tshuaj tua kab mob hnyav uas yuav ua rau cov coatings tsawg dua.
Precision Cheebtsam (shafts & Gears)
Rau kev txav CNC qhov chaw xws li lub zog, ncej, thiab pistons, qhov sib txhuam qis ntawm CrN txheej txo qhov hnav ntawm qhov chaw mating. Los ntawm kev siv CrN txheej, peb tuaj yeem txuas ntxiv qhov kev pabcuam ntawm cov tshuab siv tshuab.
Xaus
Kev kho dua tshiab los ntawm cov hlau tsis muaj coated lossis tus qauv TiN rau CrN txheej tuaj yeem ua rau muaj kev txhim kho tam sim ntawd hauv kev ua haujlwm ntev thiab kev ua haujlwm ntau lawm. Txawm hais tias koj tab tom tawm tsam corrosion hauv cov pwm txhaj tshuaj lossis sim txo kev sib txhuam hauv cov khoom sib dhos, Chromium Nitride txheej muaj qhov muaj zog, tus nqi - siv tau zoo.
