Paslanma tipik olarak metallerin oksijen, su vb. varl\u0131\u011f\u0131nda oksidasyon reaksiyonuna girerek gev\u015fek oksitler olu\u015fturmas\u0131 anlam\u0131na gelir (\u00f6rne\u011fin demir pas\u0131 Fe\u2082O\u2083\u30fbnH\u2082O olu\u015fturur). Tungsten karb\u00fcr\u00fcn korozyon direnci, e\u015fsiz bile\u015fimi ve yap\u0131s\u0131ndan kaynaklanmaktad\u0131r:

Tungsten, oda s\u0131cakl\u0131\u011f\u0131nda oksijen veya su ile neredeyse hi\u00e7 reaksiyona girmeyen, y\u00fcksek erime noktal\u0131, olduk\u00e7a inert bir metaldir.

Bu nedenle, saf WC sert faz\u0131n\u0131n kendisi \u00e7evre ile oksidatif reaksiyonlara girmez ve do\u011fal olarak paslanma g\u00f6stermez.<\/p>\n\n\n\n

Demir kimyasal olarak aktif bir metaldir. Nemli havaya, ya\u011fmur suyuna veya asidik\/alkali ortamlara maruz kald\u0131\u011f\u0131nda h\u0131zla oksidasyona u\u011frar: Fe + O\u2082 + H\u2082O \u2192 Fe\u2082O\u2083\u30fbnH\u2082O (demir pas\u0131).
Bu t\u00fcr tungsten karb\u00fcr\u00fcn paslanma \u00f6zellikleri \u00e7ok belirgindir: y\u00fczeyde k\u0131rm\u0131z\u0131ms\u0131 kahverengi lekeler veya s\u00fcrekli pas tabakalar\u0131 ortaya \u00e7\u0131kar ve sadece g\u00f6r\u00fcn\u00fcm\u00fc etkilemekle kalmaz, ayn\u0131 zamanda yap\u0131sal hasara da neden olur.

Demir bazl\u0131 ba\u011flay\u0131c\u0131 faz tungsten karb\u00fcr tipik olarak son derece d\u00fc\u015f\u00fck korozyon direnci gereksinimleri olan senaryolarda kullan\u0131l\u0131r (\u00f6rne\u011fin, genel i\u015flemede kaba kesme tak\u0131mlar\u0131, d\u00fc\u015f\u00fck y\u00fck a\u015f\u0131nmas\u0131na dayan\u0131kl\u0131 par\u00e7alar).

Kobalt kimyasal olarak demirden \u00e7ok daha inerttir ve kuru havada ve oda s\u0131cakl\u0131\u011f\u0131ndaki n\u00f6tr ortamlarda g\u00fc\u00e7l\u00fc bir stabilite sergiler, bu nedenle bu t\u00fcr \u00fcr\u00fcnler genellikle paslanmaya kar\u015f\u0131 dayan\u0131kl\u0131 olarak kabul edilir. Ancak, kobalt kesinlikle korozyona dayan\u0131kl\u0131 de\u011fildir. A\u015fa\u011f\u0131daki \u00f6zel ko\u015fullar alt\u0131nda, oksidatif korozyon yine de meydana gelebilir (geleneksel k\u0131rm\u0131z\u0131 pas olmasa da, daha geni\u015f anlamda paslanma olarak kabul edilir):
Tuzlu su veya klor i\u00e7eren ortamlara uzun s\u00fcre dald\u0131rma: \u00f6rne\u011fin, deniz ortamlar\u0131, kimya end\u00fcstrisindeki klor i\u00e7eren \u00e7\u00f6zeltiler. Klor\u00fcr iyonlar\u0131 kobalt y\u00fczeyindeki pasif filmi tahrip ederek \u00e7ukur korozyonuna neden olabilir ve siyah CoO veya kahverengi-siyah Co\u2083O\u2084 oksit tabakalar\u0131 olu\u015fturabilir.
G\u00fc\u00e7l\u00fc asit ve g\u00fc\u00e7l\u00fc alkali ortamlar: Hidroklorik veya s\u00fclf\u00fcrik asit gibi g\u00fc\u00e7l\u00fc asitlerde veya sodyum hidroksit gibi g\u00fc\u00e7l\u00fc alkalilerde, kobalt\u0131n pasif filmi \u00e7\u00f6z\u00fcnerek kimyasal korozyona, y\u00fczey \u00e7ukurla\u015fmas\u0131na ve hatta a\u011f\u0131rl\u0131k kayb\u0131na yol a\u00e7abilir.
Y\u00fcksek s\u0131cakl\u0131k, y\u00fcksek nem ve bol oksijen: \u00f6rne\u011fin, y\u00fcksek s\u0131cakl\u0131ktaki buhar ortamlar\u0131, g\u00fcne\u015f ve ya\u011fmura uzun s\u00fcre a\u00e7\u0131k havada maruz kalma kobalt oksidasyonunu h\u0131zland\u0131rabilir. Oksit tabakas\u0131 nispeten yo\u011fun olsa da, uzun s\u00fcreli birikim y\u00fczey kalitesini ve performans\u0131 etkileyebilir.
Hasarl\u0131 y\u00fczey kaplamalar\u0131: Tungsten karb\u00fcr \u00fcr\u00fcnlerde krom kaplama veya nitr\u00fcrleme gibi korozyon \u00f6nleyici kaplamalar varsa, kaplaman\u0131n hasar g\u00f6rmesi i\u00e7 kobalt bazl\u0131 ba\u011flay\u0131c\u0131 faz\u0131 a\u00e7\u0131\u011fa \u00e7\u0131kararak korozif ortam\u0131n do\u011frudan temas etmesine ve lokal paslanmaya neden olur.
Kobalt bazl\u0131 ba\u011flay\u0131c\u0131 faz tungsten karb\u00fcrdeki paslanma \u00e7o\u011funlukla lokalize oksidasyondur, demir bazl\u0131 \u00fcr\u00fcnlerdeki gibi yayg\u0131n gev\u015fek paslanma de\u011fildir. Ancak yine de \u00f6zellikle y\u00fcksek hassasiyetli, y\u00fcksek g\u00fcvenilirlikli uygulamalarda \u00fcr\u00fcn \u00f6mr\u00fcn\u00fc ve hassasiyetini etkileyebilir.<\/p>\n\n\n\n

Ba\u011flay\u0131c\u0131 faz olarak nikel (Ni) veya nikel-krom ala\u015f\u0131mlar\u0131 kullanan tungsten karb\u00fcr, \u015fu anda mevcut olan en iyi korozyon direncini sunar ve geleneksel ortamlarda neredeyse paslanmaz. Nikel kimyasal olarak kobalt ve demirden \u00e7ok daha inerttir. Oda s\u0131cakl\u0131\u011f\u0131nda, y\u00fczeyinde oksijeni, suyu ve \u00e7o\u011fu a\u015f\u0131nd\u0131r\u0131c\u0131 maddeyi etkili bir \u015fekilde bloke eden yo\u011fun, pasif bir oksit filmi olu\u015fturarak nemli veya hafif asidik\/alkali ortamlarda bile stabilitesini korur.
Baz\u0131 karma\u015f\u0131k ortamlarda bile nikel bazl\u0131 ba\u011flay\u0131c\u0131 fazlar ola\u011fan\u00fcst\u00fc korozyon direnci g\u00f6sterir. N\u00f6tr tuz spreyine ve zay\u0131f asidik \u00e7\u00f6zeltilere kar\u015f\u0131 g\u00fc\u00e7l\u00fc tolerans g\u00f6sterirler. Tuz p\u00fcsk\u00fcrtme testlerinde, korozyon diren\u00e7 s\u00fcreleri kobalt bazl\u0131 \u00fcr\u00fcnlerin 3-5 kat\u0131 olabilir. Korozyon yaln\u0131zca g\u00fc\u00e7l\u00fc oksitleyici asitlere (\u00f6rn. konsantre nitrik asit, kromik asit \u00e7\u00f6zeltileri) veya y\u00fcksek s\u0131cakl\u0131kta erimi\u015f tuzlara maruz kalma gibi a\u015f\u0131r\u0131 ko\u015fullar alt\u0131nda meydana gelebilir. Ayr\u0131ca, nikel bazl\u0131 ba\u011flay\u0131c\u0131 fazlar stres korozyon \u00e7atlamas\u0131na kar\u015f\u0131 iyi diren\u00e7 g\u00f6sterir, yani korozif ortama maruz kald\u0131klar\u0131nda y\u00fck alt\u0131nda \u00e7atlamaya daha az e\u011filimlidirler. Bu nedenle, nikel bazl\u0131 tungsten karb\u00fcr genellikle son derece y\u00fcksek korozyon direnci gereksinimleri olan uygulamalarda kullan\u0131l\u0131r. Tek dezavantaj\u0131, standart kobalt bazl\u0131 tungsten karb\u00fcr\u00fcn yakla\u015f\u0131k 1,5-2 kat\u0131 fiyatla daha y\u00fcksek maliyetidir.
