Harden Id Wearim Paip Ar600 Abrasen Resistan
Nikel strongpela waitpela kast ain wear-resisten paip
Nikel hat kast ain em i wanpela waitpela kast ain i gat nikel na kromium, we ol i save kolim Ni-Hard long wol. Folem kromium konten, oli save divaedem i go long tu kategori: w (Cr) 2% mo w (Cr) 9%.
Insait long wanpela nikel hat waitpela kast ain bilong 2% w (Cr), karbaid em (Fe, Cr) C, wantaim hat bilong 1100 ~ 1150 HV, i antap moa long hat bilong nomol kabid Fe, C (900 ~ 1000 HV). Long nikel hat waitpela kast ain bilong 9% w (Cr), planti kabid em (Cr, Fe) C3 wantaim bikpela hat. Ol piksa 8-6 i soim olsem Cr i bin putim Cr long fomesen bilong karbaid.
Nikel we i fulap moa long strong waet kast aen i blong impruvum kwinabiliti blong ol aean kast, we i help blong kasem wan aean matriks we i stanap long martensaet, be oltaem i go wetem wan bigfala namba blong residual austenite. Amaon blong nikel konten i dipen long tiknes blong wol blong kasting, mo nikel konten blong tik wol kasting i mas tekem hae limit.
(1) Kabon. Hap kabon kast ain i gat bikpela hat, gutpela wear resistens na pes difrens, taim liklik kabon em i vice versa. Dipend long ol difren aplikesen 2) silikon. Silikon i stap insait long Ni-Had 1 na Ni-Had 2; hai kromium konten bilong Ni-Hard 4 em i bilong 1.8%~2.0%. Hae solusen i promotem fomesen blong (Fe, Cr), C; taipim karbaid, na i skruim mak bilong tempereja M, na dispela i mekim na ol i kisim martensait matriks, tasol bikpela na liklik silikon i wok long dai.

(1) Kemikel komposesen bilong nikel hat waitpela kast ain i bin kisim nesenel standet long Saina (lukim Tebol 8-2). Ol i bin putim Stendet (ASTM) bilong Amerikan Materiel Testing Asosiesen (ASTM) bilong Amerika long Amerika na ol i brukim i go long 4-pela model A, B, C na D (lukim Apendiks E2). Long Yunaitet Kingdom, Jemani tu i orait long ol samting bilong kantri. Intanesenel Nickel Koporesen i listim tu kemikel komposesen bilong nikel hat waitpela kast ain (lukim Tebol 8-16).
(3) Kromiam. Kromiam i save helpim fomesen bilong karbaid, na i save mekim kromium i kamap gutpela moa long Ni-Hard 4 wantaim kabon na silikon, olsem na planti bilong ol koptektik karbaid i kamap (Fe, Cr) C3, i mekim gut wear resistens na impak strong i kamap .
(4) Nikel. Nickel i stap insait tru long metal matriks, we inap long kamapim gutpela wok bilong kwinabiliti na promotim fomesen bilong martenit o eskite matriks. Kwenabiliti bilong Mi-de 4 i antap tru long Ni-Hard 1, we inap mekim kasting wantaim seksen i go antap long 200mm. Nickel i save helpim grafitaisesen, olsem na nikel hat waitpela maus blupela maus mausgras i gat wanpela mak bilong kromium element bilong abrusim fomesen bilong grafit. Nickel i mekem man we i mekem meresin blong givhan, mo wan hae nikel we i stap insaed i mekem se i gat moa austenite we i stap yet.
(5) Ol Manganis. Manganese inap mekim na marasin bilong helpim ol man i stap gut, olsem na ol manganis i no gat planti samting.
(6) Molibdenum. Molibdenum i save mekem se kwinabiliti i kam gud moa mo oli save aplaem long ol tik kasting sapos i nid.
Kampani bilong mipela i save kamapim ol paip i no inap bagarap long hat, na dispela inap stretim ol paip i no inap bagarap long ol samting bilong pasim wear-resistant bihainim ol nid bilong ol kastoma.
