Services - Digital Hardness
A method for testing the hardness of metals by determining the depth of penetration of a steel ball or a diamond indentor. Resistance of a material to deformation, indentation, or penetration by means such as abrasion, drilling, impact, scratching, and/or wear, measured by hardness tests such as Brinell, Knoop, Rockwell, or Vickers. Mobile hardness testing is on the advance: in these times of cost pressure and higher quality requirements, it represents not only a quick but most of all an economical supplement to stationary hardness testing in the modern production process. The application possibilities are far ranging - this refers to both large and smaller components, especially at positions which are difficult to access.
Hardness testing is almost non destructive and in many cases used for determining parameters to differentiate and describe materials. For example, hardness values can easily provide data on the strength properties of a material. As in Vickers or Brinell hardness testing, the question as to the size of the test indentation left in the material by a Vickers diamond after applying a fixed test load also arises in Vickers hardness testing according to the Ultrasonic Contact Impedance method (UCI for short). The MIC 10 in accordance to ASTM A 1038.
