Effects of Al-based alloy powders on the mechanical behavior, corrosion resistance and infrared emissivity of polyurethane composite coatings

Aluminum (Al)-based amorphous alloys (hereinafter abbreviated as AAA) with good mechanical and anti-corrosion properties are ideal fillers for modified organic coatings. A novel polyurethane (PU)/Al/AAA composite coating was prepared by adding Al-based alloy powders, which were composed of Al and AAA powders. The effects of Al or AAA powder concentration on the mechanical behavior, corrosion resistance and infrared (IR) emissivity of PU/Al/AAA...
