Abstract: A surface coloring method of a magnesium alloy article includes: performing an anodizing treatment on the magnesium alloy article to form an anodized layer having a plurality of pores on an outer surface of the magnesium alloy article; performing an etching treatment on the anodized layer to form a plurality of pits on a surface of the anodized layer that is distant from the magnesium alloy article, in which each of the plurality of pits is in spatial communication with at least one of the plurality of pores; and performing a sealing treatment on the anodized layer after the etching treatment, so that a sealing layer is formed to seal the plurality of pores on the anodized layer. By using the surface coloring method, a surface-colored magnesium alloy article is also provided.

Abstract: A method for manufacturing a ceramic-like light metal article includes the following steps. The first step is providing a light metal article and forming an anodized oxide layer on an outer surface of the light metal article. A next step is using a sandpaper with a grit number ranging from P500 to P10000 to polish the protective layer. The polished protective layer has a surface gloss of not less than 90 GU at a 60 degree angle and a surface roughness (Ra) of less than 0.1 μm. A ceramic-like light metal article obtained by using the method is further provided and exhibits a variety of color variations and a ceramic-like appearance.
