Embodiment Construction
[0019] In order to make the structural features of the present invention and the achieved effects have a further understanding and recognition, preferred embodiments and detailed descriptions are specially used, which are described as follows:
[0020] The metal surface treatment of the known technology, which pre-embeds the alloy cast iron in the metal or alloy casting process to form a wall surface different from the metal or alloy material, or directly applies electroplating or electroless nickel plating to the metal or alloy to make the metal or alloy There is a hard metal coating of a different material, but the hardness of the above method is not high, and it is easy to damage the problem, while the existing micro-arc oxidation treatment has the problem of too large holes, and there is still room for improvement in the hardness Therefore, the present invention aims at these deficiencies, and designs the manufacturing method of the metal oxide layer to achieve the goal of ...
