TEST FOR DETERMINING THE CARBON CONTENT IN SURFACE LAYERS.

摘要

The invention relates to a BEVEL-SHARED TEST FOR SPECTRAL ANALYSIS OF THE COMPOSITION OF A SURFACE LAYER FROM THE CHARACTERISTIC WAVE LENGTH OF THE OPTICAL SPECTRUM USING PONCTUAL TASKS. / P P ACCORDING TO THE INVENTION, THE SHARPENING IS CHOSEN SO THAT THE SURFACE LAYER CAN BE ENTERED BY MEANS OF A ROW OF POINTS OR MEASURING TASKS WHICH ARE DISTRIBUTED THEREON AND WHICH THE ADJUNCTION AT A DEFINED THICKNESS OF A MARGINAL LAYER MAY BE DETERMINED BY MEASURING THEIR POSITION ON THE SURFACE STARTING FROM ONE END OF THE TEST TO THE LENGTH OF THE SAME. / P P APPLICATION TO THE CONTINUOUS MEASUREMENT OF THE CARBURATION OF STEELS. / P
