Fa'idodi, rashin amfani, da bambance-bambance tsakanin ƙarfe mai sauri da siminti carbide

1. Karfe mai sauri:

Karfe mai sauri shine babban carbon da ƙarfe mai ƙarfi. A cewar sinadaran abun da ke ciki, shi za a iya raba tungsten jerin da molybdenum jerin karfe, kuma bisa ga yankan yi, shi za a iya raba talakawa high-gudun karfe da high-yi high-gudun karfe. Dole ne a ƙarfafa ƙarfe mai sauri ta hanyar maganin zafi. A cikin yanayin da aka kashe, baƙin ƙarfe, chromium, wani ɓangare na tungsten, da carbon a cikin ƙarfe mai sauri na nau'in carbide mai ƙarfi, wanda zai iya inganta juriya na ƙarfe (taurin zai iya kaiwa HRC64-68).

Sauran ɓangaren tungsten yana narkar da shi a cikin matrix kuma yana ƙara ja taurin karfe. Jan taurin karfe mai sauri zai iya kaiwa digiri 650. Karfe mai sauri yana da ƙarfi mai kyau da ƙarfi. Bayan ƙwanƙwasa, ƙaddamarwa yana da kaifi kuma ingancin ya tabbata. Gabaɗaya ana amfani da shi don kera ƙananan kayan aiki masu rikitarwa.

2. Carbide Siminti:

Cemented carbide ne micron-order refractory high-hardness karfe carbide foda, wanda aka yi ta hanyar harbe-harbe a high zafin jiki da kuma high matsa lamba tare da cobalt, molybdenum, nickel, da dai sauransu a matsayin mai ɗaure. Abubuwan da ke cikin carbide masu zafin jiki a cikin siminti carbide ya zarce na ƙarfe mai sauri, tare da tauri mai girma (HRC75-94) da juriya mai kyau.

Hard gami ja taurin iya isa 800-1000 digiri. Gudun yankan simintin carbide ya ninka sau 4-7 fiye da na ƙarfe mai sauri. High yankan yadda ya dace.

Carbide da aka yi da siminti yana da tsayin daka, ƙarfi, juriya, da juriya, kuma ana kiransa da “haƙoran masana’antu”. Ana amfani da shi don kera kayan aikin yankan, wukake, kayan aikin cobalt, da sassa masu jurewa, kuma ana amfani da shi sosai a cikin soja, sararin samaniya da jirgin sama, sarrafa injina, ƙarfe, hako mai, kayan aikin haƙar ma'adinai, sadarwar lantarki, gini, da sauran fannoni. tare da haɓaka masana'antu na ƙasa, buƙatun kasuwa na simintin carbide yana ci gaba da ƙaruwa. Kuma a nan gaba, kera manyan makamai da na'urori, da ci gaban kimiyya da fasaha na zamani, da saurin bunkasuwar makamashin nukiliya za su kara matukar bukatar samar da ingantattun fasahohi masu inganci, da tsayayyun kayayyakin siminti na siminti. .
