In the industrial production process, an indirect method is generally adopted for measuring and controlling the position of a curved surface of a part or a part with a complex shape or a small-size part coating, namely, a standard template (standard coupler) with the same process parameters is used for coating, then the standard template is subjected to the hardness and the elastic modulus of the coating, and the test result of the standard template represents the result of the part coating.
Since the material and the surface roughness of the standard template are different from those of the actual sample, the test result of the standard template is different from that of the actual sample; particularly when part coating failure occurs, it is highly desirable to know the quality and performance parameters of the coating on the actual failed part. Therefore, it is important to measure the plating properties on the surface of the actual parts.
The existing nanoindentation tester is designed uniquely, and in order to reduce data stability in the testing process and reduce errors of repeated tests, a pressure head part of the equipment is introduced with a reference ring design. The introduction of the reference ring plays a key role in repeated measurement stability and accuracy, but the reference ring has a certain size, and the reference ring needs to be located on a flat plane with a certain area in the test process, so that after the support of the reference ring is completed, the subsequent nano-indenter indentation test is completed.
However, for the design that the surface of a key sub-part in a fuel system assembly part is provided with a plating layer, the part is of a hollow unique design and has small size, the existing nano indentation tester cannot accurately and correctly seat a reference ring of detection equipment, and the performance detection of the plating layer on an actual part cannot be effectively carried out.
