Abstract: Examples relating to coating an alloy substrate are described. For example, techniques for coating a surface of the alloy substrate with a coating layer and an exterior coat include anodizing an alloy substrate to form a metal oxide layer on surface of the alloy substrate and obtain an anodized alloy substrate. The alloy substrate is a metal alloy and the anodized alloy substrate has irregularities on surface. Thereafter, a coating layer is applied on the surface of the alloy substrate to smoothen the surface by providing a uniform covering on the irregularities of the surface. After applying the coating layer, an exterior coat is deposited on the surface of the alloy substrate.
