Description
II
Изобретение относитс к измерительной технике и может быть использовано дл определени прочностных свойств материалов при приложении к ним механических усилий.The invention relates to a measurement technique and can be used to determine the strength properties of materials when mechanical forces are applied to them.
Цель изобретени - расширение функциональных возможностей путем определени вида поверхностных дефомаций .The purpose of the invention is to expand the functionality by determining the type of surface defamations.
На фиг.1 представлена зависимост изменени работы выхода электрона от напр жений; на фиг.2 - схема устройства дл реализации способа.Figure 1 shows the dependence of the change in the electron work function on voltages; Fig. 2 is a diagram of an apparatus for implementing the method.
Устройство содержит регулируемый источник 1 питани вольтметр 2, резистор 3, предусилитель 4, нуль- индикатор 5, образец 6, исследуема поверхность 7 которого образует с колеблющимс эталонным образцом 8The device contains an adjustable power supply 1, a voltmeter 2, a resistor 3, a preamplifier 4, a null indicator 5, sample 6, the surface 7 of which forms with the oscillating reference sample 8
плоский конденсатор.flat capacitor.
Способ определени деформации образца осуществл етс следующим образом.The method for determining the strain of a sample is carried out as follows.
Образец 6 закрепл ют в устройстве (фиг.2).и измер ют работу выхода электрона с исследуемой поверхности 7 по методу контактной разности потенциалов. Образец 6 освобождают и прикладьшают нагрузку к исследуемой поверхности 7, повторно измер ют работу выхода электрона M j с исследуемой поверхности.Sample 6 is fixed in the device (Fig. 2). And the electron work function is measured from the surface 7 under test according to the method of contact potential difference. Sample 6 is released and the load is applied to the test surface 7, and the electron work function M j is re-measured from the test surface.
. Дл определени вида поверхностной деформации анализируют значение 4 f, , еслил О, то деформации имеют упругий характер, если Д О, то деформирование пластическое 1ФИГ.1),. При достижении предела текучести 6j изменение работы выхода. To determine the type of surface deformation, the value 4 f, is analyzed, if it is O, then the deformations are elastic, if Y O, then the plastic deformation (FIG. 1). Upon reaching the yield strength 6j change in work function
20 электрона резко уменьшаетс .The 20 electron is dramatically reduced.
