Solid particle erosion experiments have been conducted to study the erosion behavior of multiple graphene-based coatings. In this paper, the effects of three factors on the erosion resistance have been investigated: (1) The effect of using graphene-based coatings (2) The effect of using single and multilayer coatings with alternating graphene and polyurethane layers, (3) The effects of angles of attack and erosion duration on the single and multilayer graphene coatings. The investigation also explored the coating surface quality, adhesion, and coating hardness. Finally, two parameters were used to evaluate the efficiency of the coating systems: Material removal and the depth of the erosion scar.....
