Automated Micro Hardness Testing
LMCC has recently invested in an automated micro hardness testing machine. The system has the flexibility to measure the hardness of materials using a load of 10 g to 2 kg, using Vickers or Knoop testing methods.
The advantage of conducting hardness measurements with a Knoop indenter is that the indenter typically penetrates half as deep as a that of a Vickers indenters. Therefore Knoop hardness testing can be very useful when conducting measurements on brittle materials for example ceramics.
The system is fully automatic and will allow an array of hardness measurements to be carried out. This machine has allowed new research to be conducted on welds, which was previously very labour intensive, but has also ensured repeatable results are obtained.
