2.}} Cov tshuaj ruaj khov zoo
Acid corrosion:
Siab phosphorus txheej ua tau zoo nyob rau hauv dilute sulphuric acid, hydrochloric acid, thiab phosphoric acid (xws li corrosion tus nqi<0.1 mm/a in 5% H₂SO₄ solution), but strong oxidizing acids (such as nitric acid) may destroy the passivation film and should be used with caution.
Alkali Corrosion Kuj:
Kev ruaj khov zoo hauv kev daws teeb meem xws li Naoh thiab Koh (xws li xeb tus nqi<0.05 mm/a in 10% NaOH solution), suitable for alkaline environments such as chemical industry and ocean.
Ntsev txau corrosion resistance:
Cov tshuaj phosphorus oxide passivation zaj duab xis tuaj yeem tsim nyob rau saum npoo ntawm cov txheej txheem corrosive (xws li corrosive Ce (GB / T 10125 Txuj Ci) {3} {3}
{{0 {}} kev sib xyaw thiab cov peev xwm npog
Tshuaj Nickel-phosphorus alloy plating yog qhov tsis txaus ntseeg yog tsawg dua los yog sib sib zog nqus cov qhov tsis txaus ntseeg ± 5%, zam kev pheej hmoo ntawm kev sib cav hauv zos los ntawm kev faib tawm hauv nroog tam sim no electroplating .
The coating has a strong bond with the substrate (bonding strength>200 MPa), tsis yooj yim rau tev tawm, thiab ntxiv txhim kho cov corrosion tiv taus kev ntseeg tau .
{{02. qhov tseem ceeb cuam tshuam rau corrosion tsis kam
1. phosphorus cov ntsiab lus
Tsawg tsawg phosphorus txheej (phosphorus cov ntsiab lus 1% ~ 5%): Crystalline qauv tiv, xws li pwm nyob rau (xws li pwm saum npoo) {}
Nruab nrab phosphorus txheej (phosphorus cov ntsiab lus 5% ~ 8%): Amorcrystalline ua tau zoo dua li cov tshuaj phosphorus tsis muaj tsawg.
Siab phosphorus txheej (phosphorus cov ntsiab lus saum 8%): Qhov kev xaiv corrosous zoo tshaj, yog thawj yam kev xaiv rau cov tshuaj thiab cov khoom lag luam marine.
2. Cov txheej txheem tom qab kev kho mob
Kev Kho Cua Sov:
Kev Kho Mob Tom Ntej (xws li 300 ~ 400 Degion Rwb thaiv tsev rau lub xeev khov kho, nws yuav ua rau muaj kev pheej hmoo ntawm crystallating theem, nws yuav ua rau muaj kev pheej hmoo ntawm crystallary corrosion, uas yuav tsum tau ua kom muaj kev pheej hmoo ntawm corrosion tsis sib haum xeeb .
Sealing Kho:
Tom qab plating, chromate sealing lossis organic txheej (xws li epoxy cob) tuaj yeem sau cov txheej corrosion) tuaj yeem txuas ntxiv los ntawm 30% ~ 50%).
{{0 {}} aystrate cov khoom thiab kev kho mob
Kev nyiam huv ntawm cov roj av substrate (xws li roj stains thiab oxide nplai seem) yuav ua rau cov txheej txheej kom txo thiab ua kom corrosion micro-roj ({1}}
Cov hlau ua hlau (xws li cov hlau thiab txhuas) yuav tsum tau tsim cov tshuaj sib hloov los ntawm kev sib cav sib ceg los ntawm kev sib cav sib ceg los ntawm kev ua kom ncaj qha los ntawm kev siv tshuaj tiv thaiv ua ntej thiab cov tshuaj acid .
