Abstract
In order to discover the effect of a laser quenched substrate on the surface morphology of Cr-plating coatings, the substrate was quenched by laser discretely and then Cr-coatings were plated on the surface. There appeared periodical strips alternating with dense and loose ball-like microstructure on the surface morphology in accordance with discrete substrate. The dense and loose strips correspond with original and laser quenched zone respectively. With the help of high resolution scanning electron microscope, the chemically-etching substrate and ion etching methods were used to analyze the microstructure morphologies on the Cr-coating interface and along the thickness direction respectively. The results show that the mechanism of the periodical morphological formation of Cr-coating is that the substrate discrete characteristic is transferred to coating surface by means of the periodical characteristic of coating interface and differential Cr-coating growth mode.关键词
