Effects of annealing treatment and pre-refinement of raw material on microstructures and properties of mechanically alloyed Cr-Al composite coatings on Ti-6Al-4V alloy
文摘

Mechanical alloying method was applied to form Cr–Al coatings.

Annealing treatment was applied to improve the properties of the coating.

Coating with highly homogenized structure was prepared with refined Cr particles.

Wear and oxidation resistance of the coatings were investigated.

The coating could effectively protect the substrate.
