Nickel yakaoma chena yakakandwa iron inopfekwa-pombi isingaite
Nickel hard cast iron isimbi chena ine nickel nechromium, iyo inowanzonzi Ni-Yakaoma munyika. Zvinoenderana neiyo chromium yemukati, inogona kukamurwa kuita mapoka maviri: w (Cr) 2% uye w (Cr) 9%.
Munickel yakaoma chena yakaumbwa simbi ye2% w (Cr), iyo carbide iri (Fe, Cr) C, ine kuoma kwe1100 ~ 1150 HV, yakakwirira kudarika kuoma kweyakajairika carbide Fe, C (900 ~ 1000 HV). Mune nickel yakaoma chena yakakandwa simbi ye9% w (Cr), yakawanda carbide ndeye (Cr, Fe) C3 nekuoma kwepamusoro. Mifananidzo 8-6 inoratidza kuwedzera kweCr pane carbide formation.
Iyo nickel yakatsvikinyidzana musimbi yakaoma chena ndeyekuvandudza kugona kwe iron cast, iyo inobatsira kuwana martensite{0}based metal matrix, asi inogara ichiperekedzwa nenhamba yakawanda yasara austenite. Huwandu hwehuwandu hwenickel hunoenderana nehupamhi hwemadziro ekukanda, uye iyo nickel yemukati yemadziro gobvu yekukanda inofanira kutora muganho wepamusoro.
(1) Kabhoni. Yakakwira kabhoni yakakandwa simbi ine kuoma kwakanyanya, kupfeka kwakanaka kuramba uye musiyano wepamusoro, nepo low kabhoni ichipesana. Zvichienderana nemashandisirwo akasiyana 2) silicon. Silicon content yeNi-Hard 1 and Ni{7}}Hard 2; iyo chromium yakakwira yeNi-Yakaoma 4 inobva pa1.8%~2.0%. Mhinduro yepamusoro inokurudzira kuumbwa kwe (Fe, Cr), C; type carbide, uye inowedzera tembiricha yemaline M, zvichikurudzira kutorwa kwemartensite matrix, asi yakakwira uye yakaderera silicon inodzima.

(1) Kemikari yakagadzirwa nickel yakaoma chena yakakandwa iron yakagamuchira chiyero chenyika muChina (ona Tafura 8-2). The American Materials Testing Association Standard (ASTM) yakabatanidzwa muUnited States uye yakakamurwa kuva mhando ina A, B, C uye D (ona Appendix E2). MuUnited Kingdom, Germany yakagamuchirawo chiyero chenyika. International Nickel Corporation inonyorawo kemikari yenickel yakaoma chena yakakandwa iron (ona Table 8-16).
(3) Chromium. Chromium inosimudzira kugadzirwa kwecarbide, uye inonatsurudza kusanganiswa kwechromium muNi{2}}Hard 4 ine kabhoni nesilicon, zvekuti yakawanda yecoptectic carbide ive (Fe, Cr) C3, inovandudza kusapfeka uye kusimba kwesimba.
(4) Nickel. Nickel inonyanya kunyungudutswa musimbi matrix, iyo inogona kunyatso kuvandudza quenability uye kukurudzira kuumbwa kwemartenite kana besite matrix. Kukwana kweMi-zuva 4 kwakakwira zvakanyanya kupfuura kweNi{5}}Hard 1, iyo inogona kuita kuisa nechikamu chegumi pamusoro pe200mm. Nickel inosimudzira graphitization, saka nickel yakaoma muromo chena simbi ndebvu ine imwe huwandu hwechromium element kudzivirira kuumbwa kwegraphite. Nickel inodzikamisa iyo austenite, uye yakakwira nickel yemukati inoburitsa yakasara austenite.
(5) Manganese. Manganese inogona kudzikamisa austenite, saka manganese emukati akaderera.
(6) Molybdenum. Molybdenum inogona kuvandudza quenability uye inogona kuiswa kune yakakora castings kana zvichidikanwa.
Kambani yedu inogadzira-pombi dzisingadziviriri kupisa{1}}zvisingachinji, zvinogona kugadzirisa kusakara-pombi dzinodzivirirwa zvinoenderana nezvinodiwa nevatengi.
