High-temperature alloy plate chinhu chakasarudzika chinochengetedza kuita kwakanakisa munzvimbo dzepamusoro-tembiricha. Inoshandiswa zvakanyanya mune aerospace, simba, makemikari, uye mamwe minda. Zvakanakira zvayo zvinonyanya kuratidzwa mune zvinotevera zvinhu:

1. Yakanakisa High-Temperature Kugadzikana

High-Temperature Strength Retention: Kunyange munzvimbo dzepamusoro-soro pamusoro pe600 ° C, inochengetedza simba rakakwirira, inobereka simba, uye simba rekuneta, uye haipfavi nokukurumidza nekuwedzera kwekushisa. Semuyenzaniso, nickel-based superalloys anochengetedza akakwana ma mechanic properties pakudziya kwakapoteredza 1000°C, achisangana nezvinodiwa zvezvinhu zvakakosha zvakaita sema turbine blades.

Creep Resistance: Kana yaiswa mukushushikana kwenguva refu pakupisa kwakanyanya, zvinhu zvacho zvinoratidzira kushoma deformation (creep resistance), kudzivirira kukundikana nekuda kwekunonoka kwemaitiro deformation. Izvi zvakakosha kune zvishandiso zvakaita sematurbines uye boilers anoshanda munzvimbo dzepamusoro-tembiricha uye yakanyanya-kudzvanywa nharaunda.

2. Yakanakisa Oxidation uye Corrosion Resistance

High-Temperature Oxidation Resistance: Mumhepo yepamusoro-yekushisa kana gasi, zvinhu zvinogadzira dense oxide film (yakadai seCr₂O₃ kana Al₂O₃) pamusoro payo, kudzivirira kumwe kurwiswa kweokisijeni, kunyatsodzivisa kuora kweoxidative, uye kuwedzera hupenyu hwayo hwebasa. Semuyenzaniso, alloy plates ane chromium nealuminium anochengetedza yakanakisa oxidation resistance pane tembiricha iri pamusoro pe1000°C.

Corrosion Resistance: Alloys akakwira-tembiricha anoshingirira kumagasi ane acidic nealkaline (akadai sehydrogen sulfide nesalfur dioxide), simbi dzakanyungudutswa, uye munyu, zvichiita kuti zvienderane nemhoteredzo dzakaoma senge mareactor emakemikari, marata anopisa, uye mareactor enyukireya.

3. Yakanakisa Processability uye Structural Stability

Processability: Pasinei nesimba rayo rakakwirira, alloys anopisa anogona kuumbwa kuva akasiyana-siyana, kusanganisira mahwendefa uye machubhu, kuburikidza nemaitiro akadai sekugadzira, kukungurusa, uye welding, kuti asangane nezvinodiwa zvekugadzirwa kwezvigadzirwa zvemichina yakasiyana-siyana (yakadai semahwendefa esimbi asingadziviriri kune mabhoilers makuru uye mapaneru emakamuri ekupisa einjini dzendege).

Microstructural Stability: Kunyange nekushandiswa kwenguva refu kwepamusoro-kupisa, chimiro chemukati metallographic (yakadai sechikamu chealloy uye chimiro chezviyo) hachikwanisi kuchinja zvikuru. Izvi zvinodzivirira kukanganisa kwekuita nekuda kwekuparara kwemaitiro uye kunovimbisa kushanda kwenguva refu kwakavimbika kwezvinhu.

4. Wide Temperature Range, Inokodzera Kunyanya Mamiriro ezvinhu

Alloy plates anovhara tembiricha kubva pakati-yepamusoro tembiricha (600°C) kusvika ku-ultra-high tembiricha (pamusoro pe1200°C). Mahwendefa e-alloy ane zvinyorwa zvakasiyana-siyana akakodzera kushandiswa kwakasiyana-siyana: semuenzaniso, iron-based alloys inokodzera kutonhora pakati pe600-800 ° C, nickel-based alloys yakakodzera kutonhora pakati pe800-1200 ° C, uye cobalt-based alloys inogona kushandiswa pakupisa kwepamusoro kwenguva pfupi.

Vanogona kumira zvakasanganiswa zvinokonzerwa nekupisa kwepamusoro uye mechanical mitoro. Semuenzaniso, turbine disks muinjini dzendege dzinofanirwa kushingirira kudziya kwese kwepamusoro kwemagasi ekupisa uye masimba epakati anogadzirwa nekutenderera-kumhanya.

5. Lightweighting uye Energy Saving Potential

Zvichienzaniswa nesimbi dzechinyakare dzisingadziviriri kupisa, mamwe alloys anopisa (senge nickel-based uye titanium-aluminum-based alloys) ane density yakaderera pakuita kwakafanana kwekushisa kwepamusoro, zvichibatsira pakureruka kwemidziyo (semuenzaniso, kuderedza uremu hwezvimiro uye kushandiswa kwesimba muindasitiri yemuchadenga).

Nekuda kwekukwirira kwavo kwekushisa kwekushisa uye kugara kwenguva refu, vanogona kudzikisa huwandu hwekugadzirisa michina uye kutsiva mutengo, zvisina kunanga kuvandudza kushanda kwesimba (semuenzaniso, kushandisa yakakwirira-tembiricha alloy mahwendefa mumagetsi emagetsi boilers kunogona kuwedzera kupisa kwekupisa uye kugona kugadzirwa kwemagetsi).
