Characteristics of Electroless Nickel-Phosphorus-Potassium Titanate Whisker Composite Coating

Abstract:

Electroless nickel plating with potassium titanate whisker was co-deposited on medium carbon steel substrates. The microstructure of the composite coatings was investigated. The effect of aging temperature on the microstructure of the composite coatings was studied using X-ray diffraction. The results indicate that the composite coatings will turn into crystal state with increasing heat treatment temperature. Experimental results also show that a maximum hardness is achieved for the composite coating after heat treatment at 400°C for 1 hour. The corrosion resistance and tribological properties of the composite coatings are not inferior to those of electroless Ni-P coating.
