Description
Изобретение относитс к способам измерзни твердости материалов, в частности к способам определени микротвердости полимерных материалов.The invention relates to methods for measuring the hardness of materials, in particular, to methods for determining the microhardness of polymeric materials.
Цель изобретени - повьшение точности определени микротвердости полимерных материалов,The purpose of the invention is to increase the accuracy of determining the microhardness of polymeric materials,
Способ осуществл ют следующим образом.The method is carried out as follows.
На исследуемую поверхность полимерного материала нанос т индикатор- ньм металлический слой, причем металл дл индикаторного сло выбирают из услови :An indicator metal layer is deposited on the surface of the polymer under study, and the metal for the indicator layer is chosen from the condition:
10ten
Е Е„HER"
10ten
где Е , Е - модули упругости металла и полимера.where E, E are the elastic moduli of metal and polymer.
Затем производ т вдавливание ин- дентора в исследуемую поверхность и измер ют размеры отпечатка, образовавшегос на индикаторном слоеThen, the indenter is pushed into the surface under study and the dimensions of the imprint formed on the indicator layer are measured.
