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.
Claims19
A method for manufacturing a ceramic-like light metal article, comprising:
- providing a light metal article;
- forming an anodized oxide layer on an outer surface of the light metal article, wherein the anodized oxide layer has a plurality of pores extending towards the outer surface of the light metal article;
- forming a protective layer on the anodized oxide layer;
- and
- using a sandpaper with a grit number ranging from P500 to P10000 to polish the protective layer, wherein 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, comprising:
- a light metal article;
- an anodized oxide layer formed on an outer surface of the light metal article and having a plurality of pores extending towards the outer surface of the light metal article;
- and
- a protective layer formed on the anodized oxide layer to seal the pores, wherein the 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.
