Hardness is a critical quality characteristic of metal which is important to consider while manufacturing bigger machines. The correct hardness testing method helps manufacturers to create products with necessary requirements. Hardness testing methods stand on the sample objects and their features. Hardness testing methods stand on the sample objects and their features. and heat treatment is chosen. It is beneficial to specify the methods correctly for better results and lessen cost delays.
In the list of hardness tests, the Vickers hardness test has a vital place. The test was first applied in the 1900s and is still in use for a wide range of hardness test.
I. Why is the Vickers Hardness Test Significant?
The Vicker hardness test has a significance of uniqueness. It is the only test that can measure any test force which lies under the ISO standards, which are HV 0.01, HV 1, and HV 10. This means that the test can be applied to any sample object with any hardness.
II. What are the Applications of Vickers Hardness Test?
The Vickers hardness test methods have the widest range of applications than any other test. It is suitable for measuring the hardness of both soft objects with the strength of 8 HV only to hard objects with a hardness of 2000 HV. The Vickers test process is mainly divided into three hardness testing applications named the micro, low-load, and conventional (macro) hardness range which helps the performer to measure small surfaces. The test can be applied to applications for example testing very thin sheets. The hardness test can also be used for evaluating a hardness change object which produces a number of indentations. The test can be applied to applications for example testing very thin sheets.
III. What are the Advantages of Vickers Method?
The Vickers hardness test has the given advantages:
- The Vickers hardness test can measure the entire range of hardness values as it can evaluate all the materials and samples used for the test, whether they are soft or hard in texture.
- There is no complication in the type of testers as it has only one indenter used for every method of Vickers test.
- It can be used for Non-destructive tests which makes the test sample to utilize for other functions also.
IV. What are the Disadvantages of the Vickers Method?
The Vickers Hardness test has some disadvantages also which are as follows:
- The good preparation (grinding and polishing) of the surface of the sample is important as quality matters, otherwise, it is hard to get a precise estimation of the object as intended is evaluated optically.
- The speed of the method is not very efficient relative to Brinell or Rockwell hardness test. Apart from the time which is consumed for the preparation of the test, it takes almost a minute to complete its cycle.
- Vickers hardness test is applied with the help of Vicker hardness testers and also an optical system. This set of equipment makes the test more expensive than other hardness tests for example Brinell or Rockwell tests.
Though all hardness tests have almost the same principle, they are used for different types of applications, mostly based on the hardness characteristic of the object. Every hardness test has its own advantages and limitations. In this article, the Vicker hardness test with its significance, applications, advantages and disadvantages, is discussed. Several factors are described here for a good understanding of the hardness test.
