Study of the Crystallization Kinetics of Titanium-Contained Alloy Amorphous Coatings by Brush Plating ( II )

The aim of this paper is to use non-isothermal differential scanning calorimentry technigue (DSC) to study the crystallization kinetics of Ti-Co-Ni-P and Co-Ni-P Noncrystalline coatings by electro-brush plating According to the kinetical study the crystallization mechanism of two noncrystalline coatings may be expressed by Avrarni-Erofeev equation (n=1). The kinetics equation is d alpha/dT = A/Phi(e-E/RT)(1-a) The crystallization activation energy E of Ti-Co-Ni-P and Co-Ni-P noncrystaline coatings have been determined. The results shows they are stable noncrystalline alloy. According to the electrochemical polarization curves, the corrosion resistance of Ti-Co-Ni-P is very good.
