Quality control of carburized parts made from 15XM steel

A procedure for multiparameteric testing of the depth and hardness of a carburized layer, as well as the hardness of the core of a link bushing made from 15XM steel without the direct access to the cores material, is developed. The testing is based on the relative value of the coercive force that is measured using different schemes of magnetization of a specimen.Translated from Defektoskopiya, Vol. 40, No. 12, 2004, pp. 49–53.Original Russian Text Copyright © 2004 by Kostin, Stashkov, Nichipuruk, Sapozhnikova.This revised version was published online in April 2005 with a corrected cover date.
