Sharar-sharar-sharar-shara na gama gari da Dalilai

Babban bangaren siminti carbide shine ƙananan ƙwayar tungsten carbide foda na babban taurin. Carbide da aka yi da siminti shine samfur na ƙarshe da aka samar tare da ƙarfe na foda kuma an haɗa shi a cikin tanderu mai ƙura ko tanderun rage hydrogen. Tsarin yana amfani da cobalt, nickel, ko molybdenum a matsayin mai ɗaure. Sintering mataki ne mai matukar mahimmanci a cikin siminti carbide. Tsarin sintiri shine don dumama ƙarancin foda zuwa wani zafin jiki, ajiye shi na ɗan lokaci, sa'an nan kuma kwantar da shi don samun kayan aiki tare da halayen da ake buƙata. Tsarin simintin simintin carbide yana da rikitarwa sosai, kuma yana da sauƙi don samar da sharar da aka lalata idan kun yi wasu kurakurai. Wannan labarin zai yi magana ne game da wasu sharar gida na gama gari da abin da ke haifar da sharar.

1. Barewa

Sharar gida ta farko ta gama gari shine bawon. Peeling shine lokacin da saman simintin carbide ya bayyana tare da fasa a gefuna da bawo. Bugu da ƙari, wasu suna fitowa ƙananan ƙananan fata kamar ma'aunin kifi, fashewar fashe, har ma da jujjuyawa. Bawon ya samo asali ne saboda tuntuɓar cobalt a cikin ƙanƙara, sannan iskar da ke ɗauke da Carbon takan lalata carbon ɗin da ke cikinsa kyauta, wanda ke haifar da raguwar ƙarfin ƙaƙƙarfan ƙaƙƙarfan, wanda ke haifar da kwasfa.

2. Pores

Sharar gida ta biyu mafi yawan gama-gari ita ce filaye na fili a saman simintin carbide. Ramukan da ke da sama da micron 40 ana kiran su pores. Duk wani abu da zai iya haifar da kumfa zai haifar da pores a saman. Bugu da kari, idan akwai datti a cikin jikin da ba a jika ba da narkakken karfen ko kuma jikin da aka yi da shi yana da tsayayyen lokaci mai tsanani kuma rarrabuwar yanayin ruwa na iya haifar da pores.

3. Kumfa

Kumfa shine lokacin da akwai ramuka a cikin simintin carbide kuma suna haifar da kumbura a saman sassan da suka dace. Babban dalilin kumfa shi ne cewa jikin da aka lalata yana da isasshen iskar gas. Gas mai daɗaɗɗa ya haɗa da nau'i biyu.

4. Tsarin da bai dace ba wanda ya haifar da haɗawa da foda daban-daban.

5. Nakasa

Siffar jikin da ba ta dace ba ita ake kira nakasawa. Babban dalilan da ke haifar da nakasar sun haɗa da: yawan rarraba ƙananan ƙananan ba daidai ba ne; Jikin da aka lalata yana da ƙarancin ƙarancin carbon a gida; lodin jirgin ba shi da ma'ana, kuma farantin baya ba daidai ba ne.

6. Black Center

Wurin da ba a kwance akan alloy fracture surface ana kiransa cibiyar baƙar fata. Dalilin baƙar fata yana da yawan abun ciki na carbon ko abun cikin carbon bai isa ba. Duk abubuwan da suka shafi abun ciki na carbon na jikin da aka lalata zai shafi tsakiyar baki na carbide.

7. Karas

Har ila yau fashe-fashe abu ne na gama gari a cikin sharar siminti na siminti. Akwai nau'i biyu na fasa, daya shine compression cracks, ɗayan kuma shine oxidation cracks.

8. Yawan konewa

Lokacin da zafin jiki ya yi girma ko lokacin riƙewa ya yi tsayi sosai, samfurin zai ƙone sosai. Yawan ƙona samfurin yana sa hatsi ya yi kauri, ƙura yana ƙaruwa, kuma abubuwan haɗin gwal suna raguwa sosai. Hasken ƙarfe na samfuran da ba a kora ba ba a bayyane yake ba, kuma kawai yana buƙatar sake kunnawa.
