Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of hardness detection, in particular to a molybdenum alloy finished product hardness detection device. BACKGROUND

[0002] The indentation hardness test is a standardized method for evaluating the hardness of materials by measuring their resistance to indentation under specific load. It is widely used in the mechanical property evaluation of metals, ceramics, and composite materials. The test typically uses hardness scales such as Vickers (HV), Brinell (HB), or Rockwell (HR). The core principle is to press a geometrically defined indenter (such as a diamond tetragonal pyramid or a hard alloy ball) into the sample surface under specified conditions. After maintaining the load for a certain period, the load is removed, and the hardness value is calculated by measuring the size or depth of the residual indentation. The test process must strictly follow international standards (such as ISO 6507, ASTM E384, etc.), including control of key parameters such as sample preparation, test environment, loading rate, and holding time. The sample surface needs to be polished to ensure that the roughness meets the requirements and avoid the influence of surface defects on the test results. The selection of indentation position should avoid material defects or work-hardened areas, and at least multiple valid indentations should be measured for each sample to obtain a reliable average value. Indentation hardness testing has high precision and repeatability, and is suitable for hardness analysis from macro to micro scale, especially for high hardness materials such as molybdenum alloys. The test results can be used to evaluate the wear resistance, strength, and heat treatment effect of the material, providing key data support for process optimization and quality control.

[0003] When molybdenum alloy finished products are subjected to indentation hardness testing, slag is generated. If the slag is not cleaned up as soon as possible, it will not only affect the accuracy of the test results, but also may have some impact on the hardness testing equipment. If the indenter of the hardness testing equipment encounters hard and brittle slag during the indentation process, it may cause local stress concentration, accelerate the wear of the indenter, and even produce micro cracks, affecting the precision of subsequent tests. Especially for high hardness molybdenum alloys (such as TZM), slag may exacerbate the wear of the indenter and reduce its service life. SUMMARY
