Powder yokunyibilikisa isinyithi Stainless

Inkcazo emfutshane:

Isinyithi sesinyithi singenziwa ngezahlulo, amanzi angenasinyithi anyibilikiswa kwiziko lokungeniswa kuphuma kumngxunya wokuvuza wombhobho, i-atomize ngamanzi oxinzelelo oluphezulu, kwaye iyajiya ukufumana umgubo wentsimbi. yomile, yacocwa kwaye yafakwa, kunye nobuninzi bamanzi atomized umgubo wentsimbi ongenagwele yayiyi-2.5 ~ 3.2g / cm.Yenziwa phantsi koxinzelelo lwe-550 ~ 830MPa.Ukuxinana kuhlanjululwe kwi-hydrogen okanye kumoya we-ammonia ophelileyo ngombethe -45 ~ -50 ℃ .I-sintering sintering nayo inokusetyenziswa, ubushushu bokuntywila kwi-1120 ~ 1150 ℃ .Xa kufuneka iipropathi ezilungileyo zoomatshini kunye nokumelana ne-corrosion, kusetyenziswa ubushushu bokusilika ukuya kuthi ga kwi-1315C.

Iimpawu zemveliso

Powder yokunyibilikisa isinyithi Stainless

Isinyithi esingenasici senziwe ngentsimbi kunye ne-nitrogen yoxinzelelo oluphezulu. Amasuntswana olungumgubo ayengqukuva, ukuxinana nokupakisha okuxekethileyo kwakumalunga ne-4.8g / cm, kwaye umxholo weoksijini womgubo wawungaphantsi kwe-100 × 10. Ibhola yentsimbi engumgubo nayo inokuveliswa ngokujikeleza i-electrode pulverization enomxholo weoksijini we (40 ~ 70) × 10. Ezi powders zensimbi ezingenasici zifakwa kwi-casing, i-vacuum etywinwe, icinezela i-isostatic ngokucinezela kwi-5kPa uxinzelelo, kwaye emva koko ishushu i-isostatic ngokucinezela ngo-1050 ℃ kunye no-2kPa uxinzelelo lokuqinisa izinto. zibe iintonga compact kunye nemibhobho ngo 1200 C .Thelekisa cast eqhelekileyo kunye yakha insimbi, ukwahlulwa nickel, chromium kunye molybdenum izinto umgubo ziphathwe steel stainless incinci, ubungakanani okuziinkozo incinci kakhulu, kunye ukubandakanywa sulphide kulungile kwaye ngokulinganayo Iphuculwe:

1. Amalungu eentsimbi zomgubo wentsimbi

2. Stainless umgubo iindawo yokunyibilikisa isinyithi

3. Iimpawu zoomatshini kunye nokumelana nomhlwa.

Iintsimbi ezikhethekileyo ezingenazintsimbi ezine-molybdenum ephezulu, i-nickel, i-nitrogen kunye nomxholo we-manganese zisetyenziselwa ukuphucula ukumelana nokubola kunye namandla kwiindawo ezingaselunxwemeni ezinzima.
