The GWP covers with their equipment park the typical testing areas. Different materials like plastics, metals, coatings and ceramics can be tested.
For the characterization of different materials the hardness test offers a very wide spectrum of possibilities. With the micro hardness test usually load ranges of 1 to g e.
The GWP is equipped with the most modern hardness test devices, which offer the possibilities of manual, semiautomatic and fully automatic evaluation. Hardness test with metals. Thus, the hardness is an essential ingredient of sin calculations, drawing specifications or in the characterization of materials.
Vickers, Rockwell and Brinell. Particularly in the case of multi-layered welds, it is thus possible to identify specific areas, in which the heat input has significantly affected the microstructure, and as consequence affects the quality of the weld joint.
Hardness mapping are performed according to Vickers. These evaluations lead to conclusions about e. Instrumented penetration testing universal hardness test. 501190
GWP: Hardness test
Hardness mapping are often applied to verify welded joints. Because of this kind of determination the hardness value can be read from a scale without optical measurement devices and the requirements regarding surface quality are lower.
Filling the sample with indents hardness mapping can be useful for case-hardened parts or to check sample homogeneity.
In the tests hard metal balls with different diameters 1, 2. For the examination next to metallographic investigations also hardness profiles are used. Surface layer hardenings are common methods for improving the wear resistance of components.
From the hardness test procedures, the Vickers method is the most universally applicable test. Also in the field of damage investigation hardness profile measurements are used, to e. These apply to the expected hardness, ball diameter and test load.
Similar to the Vickers method the calculation of the hardness is based on the ratio of the average diagonal diameter for the used ball and the test load. Due to different hardness and processing methods the testing methods can be differed: A determination of the hardniss is carried out, depending on the selected test load, on the by plastic deformation caused dent by average calculation of the diagonal.
Home Lab Services Material testing Hardness test. In contrast to the Vickers and Brinell method, the hardness is determined not by the lasting dent diagonal but by the dih of penetration. The software automatically assigns colors for the minimum and maximum hardness values.
The instrumented penetration testing for the determination of hardness and other material parameter also universal hardness or hardness martens also offers the possibility to determine and estimate the elastic distortion of materials in contrast to the classical methods like Rockwell and Vickers.
Modern metal materials offer a very wide range of different operation purposes. Our according to DIN EN ISO accredited lab offers the usual stationary methods of hardness testing, which are 501900 in the field of metallic materials: Thermal and don stress can induce microstructural changes in materials, which can be detected with a hardness test.
By these small impressions also very close contiguous impressions can be realized e. Via these measurements next to 05190 hardness difference compared to the core hardness also the depth can be determined. The Rockwell method is preferably used for very hard materials or heat treatment conditions, e. Usually the examinations take place on metallographic prepared samples.
