Изобретение относитс  к области измерени  твердости .материалов.This invention relates to the field of measuring hardness of materials.

Известен индентер твердомера, выполненный из оптически прозрачного материала.Known indenter hardness tester, made of optically transparent material.

Недостатком известного устройства  вл етс  необходимость внедрени  в оптическую систему твердомера окул рмикрометра, в измерении им отпечатка возникает погрешность вследствие парралакса, что снижает его точность .A disadvantage of the known device is the need to insert an ophthalmic meter into the optical system of the hardness tester. In the measurement of its footprint, an error arises due to the parralax, which reduces its accuracy.

Целью изобретени   вл етс  повышение точности измерени  размера отпечатка. Это достигаетс  тем, что индентер снабжен отсчетной шкалой, нанесенной на его поверхность .The aim of the invention is to improve the accuracy of measuring the size of a print. This is achieved by the fact that the indenter is provided with a reference scale deposited on its surface.

На чертеже изображен предлагаемый индентер .The drawing shows the proposed indenter.

Он выполнен из оптически прозрачного материала . На одну из его поверхностей, в дан3It is made of optically transparent material. On one of its surfaces, in dan3

ном случае на тыльную поверхность А, нанесена отсчетна  шкала.The case on the back surface A is marked with a reading scale.

Индентер закрепл ют на твердомере и вдавливают в исследуемый материал.The indenter is fixed on the hardness tester and pressed into the material under study.

Затем с помошью микроскопа, не разгружа  индентера, наблюдают за отпечатком, видимым сквозь прозрачный индентер, и по шкале, нанесенной на его поверхности, измер ют размер отпечатка.Then, using a microscope, without unloading the indenter, the imprint visible through the transparent indenter is observed, and the size of the imprint is measured on a scale printed on its surface.

Предмет изобретени Subject invention

Индентер твердомера, выполненный из оптически прозрачного материала, отличающийс  тем, что, с целью повышени  точности измерени  размера отпечатка, он снабл ен отсчетной шкалой, нанесенной на его поверхность .A hardness meter indenter made of an optically transparent material, characterized in that, in order to improve the accuracy of measuring the size of a print, it is provided with a reading scale applied to its surface.
