Verifying Grinding Burn! Our Inspection Process
We analyse your parts for thermal rim zone damage. Irrespective of whether this analysis is carried out on site at your company or in the testing laboratory, we can provide you with professional and objective expertise.
Overview of the Inspection Processes
Non-destructive tests:
| Test | Abbreviation | Principle | Basics | Typical Faults |
|---|---|---|---|---|
| Radiographical test | RT | electromagnetic | EN444, EN13068, EN16016 | Foreign inclusions, pores, cracks, bonding errors |
| Penetration test | PT | mechanical | EN571-1 | Pores, cracks (must be open to the surface) |
| Magneto-inductive method | MI | magnetic | ISO 2178 | Cracks, hardness penetration depth, nitrinding depth |
| Magnetic particle test | MT | magnetic | ISO 9934 | Pores, cracks (only for ferromagnetic material) |
| Visual test | VT | optical | EN 13018, DGZfP Merkblatt, B06 | Optically visible surface irregularities |
| Ultrasound test | UT | mechanical | EN583, DGZfP Merkblatt, B04 | Cracks, bonding errors, pores, inclusions |
| Eddy current test | ET | eletrical | ISO 55549 | Cracks, surface defects |
Destructive Tests:
| Test | Abbreviation | Principle | Typical Faults |
|---|---|---|---|
| Nital etching | NÄ | chemical | Part surface coloring |
| Metallography | MET | microstructure cross section | Tempering zones, rehardening zones |
| Residual stress test | EGS | diverse | Tensile residual stresses |
| Microhardness test | MHV | mechanical | Hardness increase |
*Nital etching: incl. generation of comparison standards and diagnostic device for your own analyses, if required.
