Method for non-destructive and rapid determination of spring steel

Abstract

The present invention discloses a method for lossless and rapid determination of spring steel. According to the method, copper is adopted as a material to produce two probes, one of the probes is heated to a temperature of 200-400 DEG C, the heated probe contacts the surface of a metal material requiring detection to form a loop, electric potential difference in the loop is detected, and it is determined that the metal finished product material requiring detection is the beta type titanium alloy when the electric potential difference in the loop is 2.64-5.53 mv. According to the present invention, the Seebeck effect of the metal material is utilized, the copper is adopted as the hot end probe, the heated probe and the metal material requiring detection form the loop, and the electric potential difference in the loop is detected so as to determine whether the metal material requiring detection is the spring steel, such that the traditional metal material analysis methods such as the chemical component analysis method, the metallographic method and the like are completely changed, the sample requiring detection is not required to be transported to the laboratory, damage on the sample requiring detection can not be caused, the detection efficiency is substantially increased, the detection safety is ensured, and especially the positive effect can be provided for the non-strict material component detection of the part finished product.

Description

technical field [0001] The invention relates to the field of metal materials, in particular to a method for quickly measuring spring steel without damage. Background technique [0002] The correct use of metal materials is self-evident for giving full play to the performance of the material and improving the life of the product. Therefore, the type of metal material must be analyzed and determined. The most common analysis and detection methods are chemical composition analysis, spark grinding identification method and metallographic observation method. [0003] With the rapid development of science and technology in our country, aerospace, aviation and other technologies have made significant progress. In these technical fields, there are strict requirements on the materials of product parts. However, there may be material errors in the production process of the product, for example, when spring steel is required to be used, if other metal materials are accidentally mixed...

Problems solved by technology

However, there may be material errors in the production process of the product, for example, when spring steel is required to be used, if other metal materials are accidentally mixed in, and the product is found to be mixed after a large number of finished products have been produced , at this time, if all products are scrapped, it will inevitably cause serious waste

However, if the existing detection methods are used to detect the components of the product, not only the efficiency is low, but also the product will be damaged.

Therefore, existing detection methods cannot effectively detect finished parts
