Description
Известны способы определени состо ни хрупкости неоднородных хрупких, например, радиокерамических материалов и ферритов с использованием прибора типа Роквелла с идентером в виде алмазного конуса.Methods are known for determining the state of brittleness of heterogeneous brittle, for example, radio-ceramic materials and ferrites using a Rockwell-type device with a diamond cone identifier.
В предлагаемом способе, с целью установлени зависимости шлифуемости указанных материалов от состо ни их хрупкости, прибором Роквелла определ ют максимальную нагрузку дл испытываемого материала , при которой происходит плавное вдавливание в него алмазного конуса.In the proposed method, in order to establish the dependence of the grinability of these materials on their brittleness, the Rockwell device determines the maximum load for the material under test, in which the diamond cone is gradually pressed into it.
При осуществлении способа о плавности вдавливани суд т по движению стрелки индикатора, вл ющегос принадлежностью прибора.In the implementation of the method, the smoothness of the indentation is judged by the movement of the indicator hand, which belongs to the device.
Может также определ тьс минимальное врем , необходимое дл плавного проникновени алмазного конуса в образец при определенной дл данной группы испытываемых материалов нагрузке. Дл осуществлени этого способа прибор оснащаетс дополнительным устройством дл торможени вдавливани конуса. Этот прибор может быть выполнен или в виде гидравлического цилиндра с регулируемым размером отверсти дл перетекани жидкости, или в виде кулачкового механизма с регулируемым числом оборотов кулачка, управл ющего опусканием конуса.The minimum time required for smooth penetration of the diamond cone into the sample at the load determined for this group of test materials can also be determined. To implement this method, the device is equipped with an additional device for braking the pressing of the cone. This device can be made either as a hydraulic cylinder with an adjustable orifice for the flow of fluid, or as a cam mechanism with an adjustable number of revolutions of the cam controlling the lowering of the cone.
В имеющемс заключении указываетс , что применение предлагаемого способа позволит путем предварительных испытаний технически правильно отработать технологический процесс щлифовки радиокерамических материалов, что особенно ценно при внедрении в производство новых материалов.The conclusion indicates that the application of the proposed method will allow, through preliminary tests, to technically correctly work out the technological process of grinding radioceramic materials, which is especially valuable when introducing new materials into production.
Предмет изобретени Subject invention
Способ определени состо ни хрупкости неоднородных хрупких, например, радиокерамических материалов и ферритов с использованием пр-ибора типа Роквелла с идентером в виде- алмазного конуса, отличающийс тем, что, с целью установлени зависимости шлифуемости указанных материалов от состо ни их хрупкости, прибором Роквелла определ ют максимальную нагрузку дл испытываемого ма териала, при которой происходит плавное вдавливание в него алмазного конуса.The method for determining the brittleness of heterogeneous brittle, for example, radioceramic materials and ferrites using Rockwell-type pr-ibor with a diamond cone-shaped identifier, is characterized in that The maximum load for the tested material, at which the diamond cone is gently pressed into it, is applied.
