Description
Известны инденторы дл автоматического измерени твердости токопровод щих материалов методом вдавливани , илгеющие форму конуса, пирамиды, шарового сегмента и т. п., содержащие проводники, расположенные в теле индентора на различном рассто нии от его оси. Проводники включены в электрическую измерительную схему.Indenters are known for automatically measuring the hardness of conductive materials by the indentation method, using the shape of a cone, pyramid, ball segment, etc., containing conductors located in the body of the indenter at different distances from its axis. Conductors are included in the electrical measuring circuit.
Предлагаемый индеитор отличаетс от известных тем, что он выполнен из высокоомного материала, например карбида кремни , и непосредственно включен в электрическую измерительную схему. Это позвол ет производить непрерывное измерение твердости.The proposed inditor differs from the known ones in that it is made of a high-resistance material, such as silicon carbide, and is directly included in the electrical measuring circuit. This allows continuous measurement of hardness.
На чертеже схематически изображен описываемый инденто.р.The drawing shows schematically the described indento.
Индентор / из высокоомного материала, например карбида кремни , подключен к электрической измерительной схеме 2 с измерительным прибором 3, например высокоол ным потеиннометрическнм мостом.An indenter / of a high-resistance material, such as silicon carbide, is connected to an electrical measuring circuit 2 with a measuring device 3, for example, a high-molecular mass-measuring bridge.
При виедреиии индситора в исиытуемыи материал 4 электрическое сопротивление измерительной схемы сии/каетс и фиксируетс измерительным прибором, который может быть отградуирован непосредственно в числах тверДОСТ .When monitoring the insulator in the test material 4, the electrical resistance of the measuring circuit is / is recorded and recorded with a measuring device, which can be calibrated directly in hardened numbers.
