Purpose
The method provides the possibility of studying how the material looks inside, for example when analyzing material quality where porosity level is an important factor.
Measurement of porosity level as a continuous process controll is an effective way of controlling the process and may be used as a parameter for quality assurance of the casting process.
Measurement of porosity level gives a relatively fast indication whether the material meets the requirements regarding amount and size of porosity in a cast component.
Method
The method is based on that a sample is cut from a Component. The sample is mounted in plastic and then subjected to grinding and polishing. The sample is placed in a light optical microscope with a software for image analysis. A rather large amount of pictures from the surface of the sample is analyzed regarding number and size of porosity.
Deliveries
Report from the analysis with porosity level, most common size distribution and possibly pictures from the cross section.
