Description
Photothermal Radiometry ForaTherm
Photothermal radiometry is a non-contact and nondestructive testing method for hardness measurements (e.g. hardness profiles of case-hardened steels). Other applications are measurement of coating thickness, coating adhesion or detection of grinding burns. Whenever surface layers are altered by mechanical, chemical or heat treatment, photothermal radiometry can be considered for characterization. This technique is much faster than metallographic analyses, thus enabling inline hardness inspection. Even complete hardness depth profiles can be reconstructed for laboratory purposes.
