Sintered silicon carbide wani muhimmin yumbu abu ne mai mahimmanci, wanda aka yi amfani da shi sosai a cikin yanayin zafi mai zafi, babban matsin lamba da filayen ƙarfi. Reaction sintering na sic babban mataki ne a shirya sintered kayan SIC. Mafi kyawun iko na sintered silicon carbide dauki zai iya taimaka mana mafi kyawun sarrafa yanayin amsawa da haɓaka ingancin samfur.
1. Haɓaka halayen halayen silicon carbide
Yanayin amsawa sune mahimman sigogin halayen silicon carbide na sintered, gami da zazzabin amsawa, matsa lamba, rabo mai amsawa da lokacin amsawa. Lokacin inganta yanayin amsawa, wajibi ne a daidaita daidai da ƙayyadaddun buƙatun aikace-aikacen da tsarin amsawa.
(1) Zazzabi mai amsawa: Yanayin amsawa yana ɗaya daga cikin mahimman abubuwan da ke shafar saurin amsawa da ingancin samfur. A cikin wani takamaiman kewayon, mafi girman zafin amsawa, saurin amsawa da haɓaka ingancin samfur. Koyaya, yawan zafin jiki mai yawa kuma zai haifar da haɓakar pores da fasa a cikin samfurin, yana shafar ingancin samfurin.
(2) Matsin amsawa: Matsin amsawa shima yana da tasiri akan saurin amsawa da yawan samfur. A cikin wani takamaiman kewayon, mafi girman matsi na amsawa, da sauri saurin amsawa kuma mafi girman yawan samfurin. Duk da haka, matsi mai tsayi da yawa na iya haifar da karuwa a cikin pores da fasa a cikin samfurin.
(3) Reactant taro rabo: The reactant taro rabo ne wani muhimmin factor shafi dauki gudun da samfurin ingancin. Lokacin da yawan adadin carbon zuwa silicon ya dace, ƙimar amsawa da ingancin samfur. Idan reactant taro rabo bai dace ba, zai shafi dauki gudun da samfurin ingancin.
(4) Lokacin amsawa: Lokacin amsawa yana ɗaya daga cikin abubuwan da ke shafar saurin amsawa da ingancin samfur. A cikin wani takamaiman kewayon, mafi tsayin lokacin amsawa, da rage saurin amsawa kuma mafi girman ingancin samfur. Koyaya, tsayin lokacin amsawa kuma zai haifar da haɓakar pores da fasa a cikin samfurin, yana shafar ingancin samfurin.
2. Reaction-sintering silicon carbide sarrafa tsari
A cikin tsarin amsawa na silicon carbide sintered, ya zama dole don sarrafa tsarin amsawa. Makasudin sarrafawa shine tabbatar da cewa amsawar ta tabbata kuma ingancin samfurin ya daidaita. The iko da dauki tsari ya hada da zazzabi iko, matsa lamba iko, yanayi iko da reactant ingancin iko.
(1) Kula da yanayin zafi: Kula da yanayin zafi yana ɗaya daga cikin mahimman abubuwan sarrafa tsarin amsawa. Ikon zafin jiki Ya kamata a sarrafa zafin amsawa daidai gwargwadon iko don tabbatar da ingantaccen tsarin amsawa da daidaiton ingancin samfur. A cikin samarwa na zamani, tsarin sarrafa kwamfuta yawanci ana amfani da shi don sarrafa daidaitattun zafin jiki.
(2) Kula da matsi: Kula da matsi wani muhimmin al'amari ne na sarrafa tsarin amsawa. Ta hanyar sarrafa matsin lamba, ana iya tabbatar da kwanciyar hankali na tsarin amsawa da daidaiton ingancin samfur. A cikin samarwa na zamani, ana amfani da tsarin sarrafa kwamfuta don sarrafa matsi na amsa daidai.
(3) Kula da yanayin yanayi: Kula da yanayin yanayi yana nufin amfani da takamaiman yanayi (kamar yanayi mara amfani) a cikin tsarin amsawa don sarrafa tsarin amsawa. Ta hanyar sarrafa yanayin, yana yiwuwa a tabbatar da kwanciyar hankali na tsarin amsawa da daidaiton ingancin samfurin. A cikin samarwa na zamani, yawancin yanayi ana sarrafa shi ta hanyar sarrafa kwamfuta.
(4) Reactant ingancin iko: Reactant ingancin iko ne daya daga cikin muhimman al'amurran da suka shafi tabbatar da kwanciyar hankali na dauki tsari da kuma daidaito na samfurin ingancin. Ta hanyar sarrafa ingancin masu amsawa, ana iya tabbatar da kwanciyar hankali na tsarin amsawa da daidaiton ingancin samfurin. A cikin samarwa na zamani, tsarin sarrafa kwamfuta yawanci ana amfani dashi don sarrafa ingancin reactant.
Mafi kyawun iko na silicon carbide mai amsawa shine maɓalli don shirya kayan siliki mai siliki mai inganci. Ta hanyar inganta yanayin amsawa, sarrafa tsarin amsawa da sa ido kan samfuran amsawa, ana iya tabbatar da daidaiton tsarin amsawa da daidaiton ingancin samfur. A aikace-aikace masu amfani, ana buƙatar daidaita halayen silicon carbide na sintepon bisa ga takamaiman yanayin aikace-aikacen don saduwa da buƙatun aikace-aikacen daban-daban.
