Chii chinonzi Thermal Spraying

Thermal spray iboka rematanho ekuputira umo zvakanyungudutswa (kana kupisa) zvinhu zvinopfapfaidzwa panzvimbo yakagadzirira. Iyo yekubatisa kana kuti "feedstock" inodziiswa nemagetsi (plasma kana arc) kana makemikari nzira (moto unopisa). Thermal spray coatings inogona kuva gobvu (ukobvu kubva 20 micrometers kuti akati wandei mm).

Thermal Spray Coating zvinhu zvekupfapfaidza zvinopisa zvinosanganisira simbi, alloys, ceramics, mapurasitiki, uye macomposites. Ivo vanodyiswa muhupfu kana waya fomu, vachipiswa kune yakanyungudutswa kana semi-yakanyungudutswa, uye inomhanyisa kuenda kune substrates muchimiro che micrometer-saizi zvidimbu. Kupisa kana magetsi arc discharge inowanzo shandiswa senzvimbo yesimba rekupfapfaidza kupisa. Izvo zvinogadziriswa zvinogadziriswa zvinogadzirwa nekuunganidzwa kwezvimedu zvakawanda zvakapfapfaidzwa. Iyo yepamusoro inogona kusapisa zvakanyanya, ichibvumira kuvhara kwezvinhu zvinopisa.

Thermal Spray Coating mhando inowanzoongororwa nekuyera porosity yayo, oxide yemukati, macro uye micro-kuomarara, kusimba kwebhondi, uye kushata kwepamusoro. Kazhinji, kunaka kwekuputira kunowedzera nekuwedzera particle velocities.

Mhando dze thermal spray:

1. Plasma spray (APS)

2. Detonation Pfuti

3. Wire arc spraying

4. Flame spray

5. High-velocity oxygen fuel (HVOF)

6. High-velocity air fuel (HVAF)

7. Cold spray

Zvishandiso zveKupfapfaidza Kwekupisa

Thermal spray coatings anoshandiswa zvakanyanya mukugadzira turbines gasi, injini dzedhiziri, mabearings, majenari, pombi, compressors, uye oiri yemunda michina, pamwe nekupfekedza maimplants ekurapa.

Kupfapfaidza kwemafuta ndiko kunyanya imwe nzira yearc welded coatings, kunyangwe ichishandiswawo seimwe nzira kune mamwe maitiro epamhepo, senge electroplating, yemuviri uye kemikari vapor deposition, uye ion implantation yeinjiniya application.

Zvakanakira Kupfapfaidza Thermal

1. Yakazara sarudzo yezvokupfekedza zvinhu: simbi, alloys, ceramics, cermets, carbides, polymers, uye mapurasitiki;

2. Makobvu machira anogona kuiswa pakakwirira deposition rates;

3. Thermal pfapfaidzo coatings vari mechanically bonded kune substrate - anogona kazhinji kupfapfaidza unhani zvinhu izvo metallurgically zvisingaenderani ne substrate;

4. Inogona kupfapfaidza zvinhu zvekuputira nepamusoro pekunyungudika kupfuura substrate;

5. Zvikamu zvizhinji zvinogona kupfapfaidzwa nechinguva chiduku kana pasina preheat kana post-heat treatment, uye kukanganisa kwechikamu kuduku;

6. Zvikamu zvinogona kuvakwa zvakare nekukurumidza uye nemutengo wakaderera, uye kazhinji pane chidimbu chemutengo wekutsiva;

7. Nekushandisa premium zvinhu zve thermal spray coating, hupenyu hwezvikamu zvitsva hunogona kuwedzerwa;

8. Thermal spray coatings inogona kushandiswa zvose nemaoko uye mechanized.
