Manyan Matakai Hudu na Tungsten Carbide Heat Jiyya

Tungsten carbide yana da babban aiki tare da kyawawan kayan aikin injiniya da kayan jiki, gami da juriya mai ƙarfi, juriya na lalata, ƙarfin lanƙwasa, ƙarfin torsion, da dai sauransu, ana amfani da ko'ina don yankan kayan aikin, gyare-gyaren sanyi, sassa, da sauransu. Labarin kuma a taƙaice ya gabatar da huɗun. manyan matakai na tungsten carbide zafi magani, wanda zai iya inganta jiki da kuma inji Properties na m gami.

Za a iya raba tsarin kula da zafi na tungsten carbide zuwa manyan matakai hudu.

1. Cire kayan gyare-gyare da kuma pre-sintering

A mataki na farko na sintering, mai kafa wakili a hankali ya rushe ko ƙafewa, ban da jikin da aka yi da shi, a lokaci guda, abubuwan da suka kirkiro suna yin carburize sintering, kuma adadin carbon zai bambanta dangane da nau'i, adadin, da kuma tsari na sintering. . Powder surface oxide yana rage, kuma hydrogen zai iya rage cobalt da tungsten oxides a sintering zafin jiki. Tare da raunin raunin da ke tsakanin carbon da oxygen, an cire damuwa na lamba tsakanin ƙwayoyin foda a hankali. A bonding karfe foda fara amsa da recrystallization da surface yadawa fara faruwa. Ƙarfin toshe ya ƙaru.

2. Mataki na m-lokaci sintering (800°C - eutectic zafin jiki)

A gaban wani lokaci na ruwa, baya ga aiwatar da ci gaba da mataki na baya, m-lokaci halayen da yaduwa suna kara tsananta tare da karuwa a cikin filastik kwarara, kuma bayyananne shrinkage bayyana a cikin sintered jiki.

3. Matakin sinterin ruwa-lokaci (zazzabi na eutectic - zafin jiki)

Lokacin da yanayin ruwa na jikin sintered ya faru, an gama matsawa da sauri, sannan kuma canjin crystallization yana faruwa. An kafa tsari na asali da tsarin carbide.

4. Matakin sanyaya (zazzabi mai zafi - zafin jiki)

A wannan mataki, ƙungiyoyi da sassan sassan tungsten carbide suna fuskantar wasu canje-canje a ƙarƙashin yanayi daban-daban na sanyaya, wanda ya sa ya yiwu a yi amfani da wannan fasalin; zafi magani na wuya gami zai inganta ta jiki da kuma inji halaye.

ZZBETTER ta sadaukar da kanta don samar da samfuran carbide masu daraja da inganci na tungsten. An sayar da kayayyakin mu zuwa kasashe da yankuna da yawa kuma suna samun babban nasara a kasuwannin cikin gida.

Idan kuna sha'awar samfuran carbide tungsten kuma kuna son ƙarin bayani da cikakkun bayanai, zaku iya tuntuɓar mu ta waya ko wasiƙa a hagu, ko Aika wasiƙun Amurka a kasan shafin.
