DUPLEX CHROME (Cr+Cr)
Microcracked chromium deposits obtained from systems using a single-deposit systems are easier to operate, but, usually have an adverse effect on the covering power of the chromium deposit. Duplex chromium systems have resolved this problem by using two successive chromium plates which cover and create the microcrack pattern.
NiCro is a solution when extreme operational condictions are mixture with drastic enviroments or/and long service life or/and requirements of highly corrosion proteccion. This duplex plating provides the ductibility and corrosion protection of nickel sulfamate and the low friction coefficient and wear resistance of the hard chrome.
