Description
Изобретение относитс к области испытаний материалов.This invention relates to the field of material testing.
Известен способ определени толщю1ы . упрочненного наклепом поверхностного сло по авторскому свидетельству № 493696, .заключающийс в том, что из исследуемой детали вырезакгг плоский образец, шлифуют его и полируют плоскость реза, секущую упрочненный слой, затем образец подвергают пластическому деформированию в направлении, параллельном упрочненному слою, и за искомую величину принимают рассто ние от наклепанной поверхности до точки начала отклонени профил реза от плоскостиThere is a known method for determining the thickness. hardened by hardening of the surface layer according to the author's certificate No. 493696. take the distance from the riveted surface to the point of the beginning of the deviation of the cut profile from the plane
Недостатком известного способа вл етс низка точность определени толщины из-за нечеткой границы отклонени профил реза от плоскости.The disadvantage of this method is the low accuracy of determining the thickness due to the fuzzy border of the deviation of the cut profile from the plane.
Целью изобретени вл етс повышение точности определени толщины .упрочненного сло .The aim of the invention is to improve the accuracy of determining the thickness of the strengthened layer.
Указанна цепь достигаетс тем, что пластическую деформацию образца осуществл ют ударом. Это позвол ет сделатьThis chain is achieved by the fact that the plastic deformation of the specimen is carried out by impact. This allows
Границу перехода от упрочненной зоны к неупрочненной более четкой.Border of transition from the strengthened zone to the not strengthened more accurate.
Предложенный способ осуществл ют следующим образом.The proposed method is carried out as follows.
Деталь из металлического материала подвергают поверхностному упрочнению, из нее вырезают плоский образец, шлифуют его и полируют плоскость реза, секуШую упрочненный слой. Затем образен поо вергают пластическому деформированию ударным воздействием в направлени , параллельном упрочненному слою, и за толщину упрочненного сло принимают рассто ние от наклепанной поверхности до . точки начала отклонени про(|ил реза от плоскости.A part from a metal material is subjected to surface hardening, a flat sample is cut out of it, polished, and the cutting plane is polished. Then the plastic deformation is formed by shock impact in the direction parallel to the reinforced layer, and the distance from the surface of the hardened layer to the thickness of the strengthened layer is taken. point of onset of deviation of pro (| or cut from the plane.
