A distinctive feature of the Vickers hardness test is its simplicity. Hardness of the samples has been evaluated by using Vickers Hardness Test. The Corrosion behaviour of as-received and thermally oxidised samples have been evaluated by using weight loss method.
A Vickers hardness tester. The Vickers hardness test was developed in 1921 by Robert L. Smith and George E. Sandland at Vickers Ltd as an alternative to the Brinell method to measure the hardness of materials. [1] The Vickers test is often easier to use than other hardness tests since the required calculations are independent of the size of the indenter, and the indenter .produced by gradual loading. There fore, impact tests are performed to asses shock absorbing capacity of materials subjected to suddenly applied loads. These capabilities are expressed as (i) rupture energy (ii) modulus of rupture and (iii) notch impact strength. Two types of notch impact tests are commonly 1. Charpy test 2.

OBJECT: To determine the hardness no. of mild steel, carbon steel, brass and aluminum specimens. At low values (VH<~400HV), Vickers hardness was shown to be the same as Brinell hardness (see hardness conversion section). Schematic representation of the Vickers test is shown in Figure 1. Further information regarding existing standards and procedures can be found in references [1,2]. Vickers hardness formula. The Vickers hardness (HV) is .Micro hardness testing for your laboratory according to Vickers, Knoop and Brinell Load range from 0.00025 to 62.5 kg Inform now and request for quotation!cutting. Mainly there are three types of hardness tests. 1) Indentation test 2) Abrasion or wear test 3) Scratch test. Of these the most important tests are based upon the principles of indentations and are the Brinell's, Rockwell and Vickers's hardness tests. In each case the material under test is indented by another body to which a static .
In Vickers hardness testing, a square pyramidal diamond indenter with specified face angles is used (see figure below). After the pyramidal diamond tip (indenter) is pressed into the test sample at a perdetermined load (F[N]), the indentation on the sample is measured using a microscope.
