Testing the hardness of tungsten wire for textiles weaving gloves usually involves the following methods, which can help evaluate the wear resistance and mechanical properties of tungsten wire:
- Vickers Hardness Test
Method: Use a pyramid-shaped diamond indenter to press into the surface of the tungsten wire under a constant load. The hardness value is calculated by measuring the diagonal length of the indentation.
Advantages: Applicable to high-hardness materials and can obtain very detailed hardness values.
- Brinell Hardness Test
Method: Press a hard steel ball or carbide ball into the surface of the tungsten wire under a certain load, and measure the diameter of the indentation to calculate the hardness.
Advantages: Applicable to larger sample surfaces and relatively uniform materials.
- Rockwell Hardness Test
Method: Use a conical diamond or steel ball indenter on the surface of the tungsten wire to measure the indentation depth under different loads to calculate the hardness.
Advantages: Fast and applicable to small samples, and can directly read the hardness value.
- Knoop Hardness Test
Method: Use a diamond indenter with a long diagonal line to press into the surface of the tungsten wire under a constant load, and determine the hardness value by measuring the long diagonal line of the indentation.
Advantages: Especially suitable for thin films and small samples.
- Microhardness Test
Method: Utilize a microscopic version of the Vickers or Knoop hardness test, which is suitable for tiny areas of tungsten wire.
Advantages: Hardness measurement can be performed on a microscopic scale, suitable for very fine wires.
- Material Hardness Tester
Method: Use a dedicated material hardness tester to perform hardness measurements according to different test standards (such as Vickers, Brinell, Rockwell, etc.).
Advantages: These testers usually have automation functions, which can improve the accuracy and efficiency of the test.
Test Steps
Sample Preparation: Make sure the surface of the tungsten wire is clean and flat, and the sample can be polished to remove the surface oxide layer if necessary.
Select the test method: Select the appropriate hardness test method according to your needs.
Conduct the test: Perform the test according to the operating procedures of the test method and record the test results.
Result analysis: Analyze the test results and perform necessary calculations to obtain the hardness value of the tungsten wire.
