Gịnị bụ Thermal Spraying

Igwe ọkụ ọkụ bụ otu usoro mkpuchi nke a na-efesa ihe gbazere (ma ọ bụ kpụ ọkụ n'ọnụ) n'elu ebe a kwadebere. A na-ekpo ọkụ ihe mkpuchi ma ọ bụ ''ihe nri'' site na eletriki (plasma ma ọ bụ arc) ma ọ bụ ụzọ kemịkal (ire ọkụ). Ihe mkpuchi mkpuchi okpomọkụ nwere ike ịdị oke (ọkpụrụkpụ sitere na 20 micrometers ruo ọtụtụ mm).

Ihe mkpuchi ọkụ na-ekpo ọkụ maka ịgbasa ọkụ gụnyere ọla, alloys, ceramik, plastik, na ihe ndị mejupụtara. A na-enye ha nri n'ụdị ntụ ntụ ma ọ bụ waya, na-ekpo ọkụ ka ọ bụrụ ala a wụrụ awụ ma ọ bụ nke ọkara gbazere, ma mee ngwa ngwa gaa n'ụdị ihe dị n'ụdị micrometer. A na-ejikarị ọkụ ọkụ ma ọ bụ mgbapụ ọkụ eletrik eme ihe dị ka isi iyi ike maka ịgbasa ọkụ. Ihe mkpuchi a na-esi na ya pụta na-eme site na nchịkọta nke ọtụtụ ihe ndị na-efesa. Elu nwere ike ghara ikpo ọkụ nke ukwuu, na-enye ohere mkpuchi nke ihe ndị na-ere ọkụ.

A na-enyochakarị ogo mkpuchi mkpuchi thermal site na ịlele porosity ya, ọdịnaya oxide, nnukwu na obere siri ike, ike nkekọ, na adịghị ike elu ya. N'ozuzu, mkpuchi mkpuchi na-abawanye na-abawanye ngwa ngwa ngwa ngwa.

Ụdị nke ịgbasa thermal:

1. Plasma spray (APS)

2. Egbe mgbawa

3. Waya arc spraying

4. Ịgba ọkụ

5. Mmanụ ikuku oxygen dị elu (HVOF)

6. mmanụ ọkụ ikuku dị elu (HVAF)

7. Ịgba oyi

Ngwa nke Spraying thermal

A na-ejikarị ihe mkpuchi ọkụ na-ekpo ọkụ na-emepụta turbine gas, engines diesel, bearings, akwụkwọ akụkọ, nfuli, compressors, na akụrụngwa mmanụ, yana mkpuchi mkpuchi ahụike.
