Формула изобретенияClaim Способ определения степени поверхностного упрочнения материалов, заключающийся в том, что в исследуемый материал внедряют индикатор и измеряют размеры отпечатка, отличающийся тем, что, с целью повышения производительности измерений, используют дополнительный индентор и эталонный материал, инденторы выполяют с углом раскрытия при вершине 160—180°, внедряют одновременно их в исследуемый материал и в эталонный, определяют разность глубин внедрения инденторов и судят о степени поверхностного упрочнения по этой разности.A method for determining the degree of surface hardening of materials, namely, that an indicator is introduced into the test material and fingerprint sizes are measured, characterized in that, in order to increase the measurement performance, an additional indenter and reference material are used, indenters are performed with an opening angle at apex of 160-180 °, they are simultaneously introduced into the studied material and into the reference material, the difference in the depths of the indenter penetration is determined, and the degree of surface hardening is judged by this difference.
