Embodiment
In order to describe structure of the present utility model and characteristics in detail, existing following preferred embodiment of act and conjunction with figs. are described as follows.
As shown in Figure 1 and Figure 2, the light alloy potteryization fastenings 10 for the utility model first preferred embodiment is provided includes: a fastenings idiosome 20 and a class ceramic layer 30.
Class ceramic layer 30 is formed at fastenings idiosome 20 surfaces with class ceramic treatment (ceramic-like coating process).The class ceramic treatment is selected from differential arc oxidation anodising (micro arc oxidizationanodizing in the present embodiment; MAO anodizing), electricity slurry electrolytic oxidation is handled (plasma electrolytic oxidationanodizing; PEO anodizing) and Galvano-chemistry activating anodising (electric-chemical collideoxidation anodizing; ECCO anodizing) wherein a kind of method.Class ceramic layer 30 is oxide or the nitride that forms at fastenings idiosome 20, and the thickness range of class ceramic layer 30 is 30 μ m to 900 μ m.In the present embodiment, class ceramic layer 30 is the aluminium oxide (Al that forms with the Galvano-chemistry activating anode treatment method
2O
3) and the thickness of class ceramic layer 30 reach 900 μ m.Wherein, class ceramic layer 30 is not to be used for as the restriction important document only for illustrating.
Via said structure, traditional fastenings is for using steel, and the proportion of traditional steel is as follows: the proportion of steel is about 7.9 (g/cm
3), the proportion of carbon steel is about 7.85 (g/cm
3), stainless proportion is about 7.93 (g/cm
3), present embodiment uses the light metal material, and the proportion of light metal material is as follows: the proportion of aluminium is about 2.7 (g/cm
