METHOD DETERMINING DEFORMATION OF DIFFUSION LAYER Russian patent published in 1998 - IPC

FIELD: mechanical engineering, development of technology of manufacture of parts and tools. SUBSTANCE: method consists in manufacture of samples, in determination of their tested size before and after chemical and thermal treatment and in calculation of change of size due to treatment. For obtainment of technical result lied in generation of information on thickness of diffusion layer linear deformation of sample over entire length and of core are determined. Deformation of diffusion layer is calculated by difference of entire length and core that is related to thickness of diffusion layer found after chemical and thermal treatment. EFFECT: obtainment of authentic information on thickness of diffusion layer.
