Kurapa kwepamusoro pekugadzirisa kuri kugadzira nzira yepasi pedhizaini pane iyo substrate zvinhu pamusoro, iyo ine akasiyana mechanic, emuviri uye kemikari zvimiro zvine substrate zvinhu.Chinangwa chekurapa kwepamusoro ndechekusangana nechigadzirwa corrosion kuramba, kupfeka kuramba, kushongedzwa kana zvimwe zvakakosha zvinoshanda zvinodiwa.
Zvichienderana nekushandiswa, nzira yekurapa yepamusoro inogona kuiswa muzvikamu zvinotevera.
Electrochemical nzira
Iyi nzira ndeye kushandiswa kwe electrode reaction kuti igadzire coating mune workpiece pamusoro.Nzira huru ndeidzi:
(A) Electroplating
Mumhinduro ye electrolyte, workpiece ndiyo cathode, iyo inogona kuumba firimu rekuvhara pamusoro pepamusoro pekuita kwekunze kwekunze, iyo inonzi electroplating.
(B) Anodization
Mumhinduro ye electrolyte, workpiece ndiyo anode, iyo inogona kuumba anodized layer pamusoro pekuita kwekunze ikozvino, iyo inonzi anodizing, yakadai sealuminium alloy anodizing.
Iyo anodization yesimbi inogona kuitwa nemakemikari kana electrochemical nzira.Chemical nzira inoiswa workpiece mumvura anodized, zvichaita anodized firimu, akadai simbi bluing kurapwa.
Chemical nzira
Iyi nzira iri kushandisa kemikari kupindirana pasina ikozvino kugadzira coating firimu pane workpiece pamusoro.Nzira dzinonyanya ndeidzi:
(A) kemikari kutendeuka firimu kurapwa
Mumhinduro ye electrolyte, iyo workpiece mukusavapo kwekunze ikozvino, kuburikidza nemhinduro yemakemikari zvinhu uye workpiece kupindirana kuumba kuvharidzira pamusoro pekuita kwayo, inozivikanwa semakemikari ekushandura firimu kurapwa.
Nekuti kupindirana pakati pemakemikari zvinhu zvemhinduro uye workpiece pasina yekunze ikozvino iyo inogona kugadzira coating firimu pane workpiece pamusoro, iyo yakadana kemikari kutendeuka firimu.Zvakadai sebluing, phosphating, passivating, chromium munyu kurapwa uye zvichingodaro.
(B) Electroless plating
Mumushonga weelectrolyte nekuda kwekudzikira kwemakemikari zvinhu, zvimwe zvinhu zvinoiswa pamusoro pechishandiso kuti zvigadzire nzira yekuisa iyo inonzi electroless plating, senge electroless nickel plating, electroless copper plating.
Thermal processing method
Iyi nzira iri kuita kuti zvinhu zvinyunguduke kana kupisa kunyunguduka mumamiriro ekupisa kwepamusoro kuumba firimu rekuputira pamusoro peiyo workpiece.Nzira dzinonyanya ndeidzi:
(A) Kupisa dip plating
Isa zvikamu zvesimbi musimbi yakanyungudutswa kuti igadzire firimu rekuputira pamusoro pebasa rekushanda, iro rainzi hot-dip plating, zvakadai se-hot-dip galvanizing, aluminium inopisa uye zvichingodaro.
(B) Thermal spraying
Iyo nzira yeatomizing uye kupfapfaidza simbi yakanyungudutswa pamusoro peiyo workpiece kuti iite coating firimu inonzi thermal spraying, senge thermal spraying of zinc, thermal spraying of aluminum nezvimwe zvakadaro.
(C) Kupisa kutsika
Iyo simbi foil inopisa, yakadzvanywa inovhara pamusoro peiyo workpiece kuti iite coating film process, iyo yakadana inopisa stamping, senge inopisa foil foil uye zvichingodaro.
(D) Kemikari kupisa kurapwa
Kugadzira workpiece kubata nekemikari uye rega zvimwe zvinhu zvipinde munzvimbo yekushanda munzvimbo yakakwira tembiricha, iyo yakadana kemikari kupisa kurapwa, senge nitriding, carburizing uye zvichingodaro.
Dzimwe nzira
Kunyanya mechaniki, kemikari, electrochemical, nzira yemuviri.Nzira huru ndeidzi:
(A)Painting coating (B) Strike plating (C) laser surface finish (D) Super-hard film technology (E) Electrophoresis uye electrostatic spraying
