METHOD FOR CHECKING THE DEPTH OF DIFFUSION LAYER IN CHEMICAL-HEAT TREATMENT Russian patent published in 1995 - IPC

Abstract RU 2031183 C1

FIELD: metallurgy. SUBSTANCE: depth of diffusion layer in chemical-heat treatment is checked by determination of value of structural changes of metal surface in the process of saturation with the aid of bimetallic plate which is rigidly attached with its one end to furnace vessel. Bimetallic plate is made of saturated metal and metal which is not liable to saturation under the given conditions. Value of diffusion layer is determined by the value of plate deformation. EFFECT: higher efficiency.
