Description
В насто щее врем в технике примен ютс различные способы измерени тонкослойных покрытий на металлах и иных материалах. Каждый из этих способов пригоден в определенной области.Currently, various methods for measuring thin-layer coatings on metals and other materials are used in the technique. Each of these methods is suitable in a specific area.
Универсальным способом вл етс распиловка издели , шлифовка и полировка разреза и просмотр разреза под микроскопом. Но при этом способе порт тс издели . Этот способ может быть применен дл выборочного контрол , а также дл предварительной градуировки уст ройств, основанных на других принципах, в том числе и дл предлагаемого способа.A universal way is to cut the product, grind and polish the cut and view the cut under the microscope. But with this method of porting products. This method can be applied for sampling control, as well as for preliminary calibration of devices based on other principles, including the proposed method.
Предлагаемый способ определени толщины поверхност: ого сло металлических изделий, имеющего твердость, превышающую твердость основного металла, обеспечивает возможность определени толш,ины сло цементации, наклепа, азотировани и т. п.The proposed method for determining the thickness of a surface: a layer of metal products having a hardness exceeding the hardness of the base metal makes it possible to determine the thickness, the size of the layer of cementation, the work hardening, the nitriding, etc.
Сущность предлагаемого способа заключаетс в том, что исследуемое изделие устанавливаемс на пресс Роквелла под aл aзное острие, стандартные грузы с пресса снимаютс п вместо них подвешиваетс какое-либо устройство, позвол ющее измен ть давление алмазного наконечника на изделие путем скачкообразно нарастающей нагрузки. При этом замер ют величину погружени алмазного наконечника s металл и по скачкообразности погружени наконечника определ ют границы слоев металла, имеюндих разную твердость.The essence of the proposed method lies in the fact that the product under test is placed on the Rockwell press under the apex, the standard weights are removed from the press and some device is suspended instead of them, allowing the diamond tip to change the pressure on the product by an abruptly increasing load. In this case, the immersion value of the diamond tip s metal is measured, and the boundaries of the metal layers, which are different in hardness, are determined from the abruptness of the tip immersion.
Полученные данные нанос т на график. Если на проколотой толщине материал однороден, то график имеет вид плавной кривой. Если же имеетс слоистость, то получаетс крива с заметными изломами или ступеньками. Ординаты изломов на графике представл ют в некотором масштабе ординаты плоскостей, раздел ющих неоднородные по твердости слои исследуемого издели . Масштаб ординат можно определить или расчетом по известным данным пресса Роквелла (и примен емых на нем алмазных наконечников) или эмпирически, проПред м е т и з о б р с т е и и The data obtained is plotted on a graph. If the material is homogeneous at the punctured thickness, then the graph has the form of a smooth curve. If there is a layering, then a curve is obtained with noticeable kinks or steps. The ordinates of kinks on the graph represent, on some scale, the ordinates of the planes separating the layers of the article under investigation which are not uniform in hardness. The scale of the ordinates can be determined either by calculation based on the known data of the Rockwell press (and diamond tips used on it) or empirically, taking into account the
