The aim of this paper is to use non-isothermal differental scanning calorimentry tech-nigue (DSC) to study the crystallization kinetics of Ti-Co-Ni-P and Co-Ni-P Noncrystalline coat-ings by electro-brush plating.According to the kinetical study,the crystallization mechamism of two noncrystalline coatings may be expressed by Avrami-Erofeev equation (n=1). The kinetics equation isThe crystallization activation energy E of Ti-Co-Ni-P and Co-Ni-P noncrystaline coatings have been determined. The result shows they are stable noncrystalline alloy. According to the electro-chemical polarization curves, the corrosion resistance of Ti-Co-Ni-P is very good.
