Kodi Thermal Spraying ndi chiyani

Kupopera kotentha ndi gulu la njira zokutira momwe zida zosungunuka (kapena zotenthetsera) zimapopera pamalo okonzeka. Zomatira kapena  "feedstock" zimatenthedwa ndi magetsi (plasma kapena arc) kapena njira zamakemikolo (lawi loyaka). Zopaka zopopera zotentha zimatha kukhala zokhuthala (kukhuthala kumayambira 20 micrometer mpaka mamm angapo).

Zida zokutira za Thermal Spray popopera mafuta zimaphatikizanso zitsulo, aloyi, zoumba, mapulasitiki, ndi ma composites. Amadyetsedwa mu mawonekedwe a ufa kapena waya, amatenthedwa mpaka kusungunuka kapena theka-wosungunuka, ndipo amathamangira ku magawo ngati tinthu tating'onoting'ono tating'onoting'ono. Kuyaka kapena kutulutsa kwamagetsi kwamagetsi kumagwiritsidwa ntchito ngati gwero lamphamvu pakupopera mbewu mankhwalawa. The chifukwa zokutira amapangidwa ndi kudzikundikira ambiri sprayed particles. Pamwamba pakhoza kutentha kwambiri, kulola kupaka zinthu zoyaka moto.

Kupaka kwa Thermal Spray Coating nthawi zambiri kumawunikidwa poyesa porosity yake, oxide content, macro ndi micro-hardness, mphamvu zomangira, komanso kuuma kwa pamwamba. Nthawi zambiri, ❖ kuyanika khalidwe kumawonjezeka ndi kuwonjezeka tinthu velocities.

Mitundu ya mankhwala opopera mafuta:

1. Utsi wa Plasma (APS)

2. Mfuti Yophulitsa

3. Kupopera mbewu kwa waya

4. Utsi wamoto

5. Mafuta a okosijeni othamanga kwambiri (HVOF)

6. High-velocity air fuel (HVAF)

7. Kupopera kozizira

Kugwiritsa Ntchito Kupopera Kwa Matenthedwe

Zopaka zopopera zotentha zimagwiritsidwa ntchito kwambiri popanga ma turbine a gasi, injini za dizilo, mayendedwe, magazini, mapampu, ma compressor ndi zida zakumunda zamafuta, komanso zokutira zoyika zachipatala.

Kupopera mbewu mankhwalawa ndi njira ina yosinthira zokutira zowotcherera ndi arc, ngakhale zimagwiritsidwanso ntchito ngati njira ina yopangira zinthu zapamtunda, monga electroplating, kuyika kwa nthunzi wakuthupi ndi mankhwala, ndi implantation ya ayoni pazauinjiniya.

Ubwino Wopopera mbewu mankhwalawa

1. Kusankha kwathunthu kwa zida zokutira: zitsulo, aloyi, zoumba, cermets, carbides, ma polima, ndi mapulasitiki;

2. zokutira zokhuthala zitha kugwiritsidwa ntchito pamitengo yayikulu;

3. Zopaka zopopera zotentha zimalumikizidwa ndi gawo lapansi - nthawi zambiri zimatha kupopera zinthu zomwe sizigwirizana ndi gawo lapansi;

4. Angathe kupopera zinthu zokutira ndi malo osungunuka kwambiri kuposa gawo lapansi;

5. Zigawo zambiri zimatha kupopera pang'onopang'ono kapena kusatenthedwa kapena kutentha kwapambuyo, ndipo kupotoza kwa chigawo kumakhala kochepa;

6. Zigawo zimatha kumangidwanso mwachangu komanso pamtengo wotsika, ndipo nthawi zambiri pamtengo wocheperako;

7. Pogwiritsa ntchito zinthu zamtengo wapatali zopaka utoto wopopera, nthawi ya moyo wa zigawo zatsopano ikhoza kuonjezedwa;

8. Zopaka zopopera zotentha zimatha kugwiritsidwa ntchito pamanja komanso pamakina.
