Conoscete la nitrurazione QPQ<\/span>?<\/span><\/strong><\/h2>\n

La nitrurazione QPQ \u00e8 un processo per la produzione di un sottile involucro ad alta durezza, resistente all'usura e alla corrosione.<\/span><\/p>\n

QPQ La nitrurazione, ampiamente utilizzata nell'industria da decenni, viene impiegata principalmente per migliorare la resistenza all'abrasione di acciaio, ghisa, acciaio inox. \"Before<\/a>e altri materiali e per migliorare la resistenza alla fatica, in particolare in combinazione con il raffreddamento ossidativo per migliorare ulteriormente la resistenza alla corrosione.<\/span><\/p>\n

Caratteristiche del processo:<\/span><\/strong><\/span><\/p>\n

La nitrocarburazione si riferisce alla penetrazione sulla superficie del materiale in acciaio di una piccola quantit\u00e0 di atomi di azoto e di carbonio. Tale trattamento chimico pu\u00f2 migliorare la resistenza all'usura e alla fatica del materiale. L'ulteriore applicazione di un bagno di raffreddamento di ossidazione unico nel suo genere, consente di ottenere un'eccellente resistenza all'usura e alla corrosione e un aspetto nero.<\/span><\/p>\n

Caratteristiche:<\/span><\/strong><\/span><\/p>\n

1.QPQ trattato con strato di permeazione di azoto al carbonio dallo strato composto (nitruro di ferro) e uno strato di diffusione.<\/span>
\n 2. Spessore dello strato composto di 10 ~ 20um, durezza Vickers di 800 ~ 1200HV.<\/span>
\n 3.Lo strato di diffusione con la quantit\u00e0 di elementi di lega in acciaio aumenta, lo spessore diventa superficiale, la durezza<\/span>
\n aumentata.<\/span><\/p>\n

Applicazioni:<\/span><\/strong><\/span><\/p>\n

Ampiamente utilizzato nell'industria manifatturiera automobilistica, nelle macchine agricole, nel settore aerospaziale, nei macchinari da costruzione, nell'edilizia e nella marina, \"after<\/a>industria chimica, industria energetica e idraulica.<\/span><\/p>","protected":false},"excerpt":{"rendered":"

Do you know QPQ Nitriding? QPQ Nitriding \u00a0is a process for producing a thin, high-hardness case that is wear and corrosion resistant.
