The aim of this paper is to use non-isothermal differental 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 mechamism of two noncrystalline coatings may be expressed by Avrami-Erofeev equation (n=1). The kinetics equation is
dα/dT=A/Фe-E/RT(1-α)
The 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 od.
