Present disclose provides " method of quality control of the coating characteristic of aluminizing of assessment drop stamping part ".Provide a kind of method of the characteristic of inspection and the plating aluminized coating for determining drop stamping part.The described method includes: removing sample from the drop stamping part to be used for glow discharge emission spectrum art (GDOES)；The sample is analyzed using GDOES；And component weight percent and depth are drawn on the diagram.The method also includes: determine the point of the component intersection on the figure, and wherein the intersection point indicates the characteristic of the plating aluminized coating.By way of example, the characteristic of the method includes: the overall thickness of the plating aluminized coating, the thickness of phase diffusion layer (IDL), the component of the plating aluminized coating, the component of the drop stamping part, phase composition, surface oxidation and the solderability of the plating aluminized coating. |
