Изобретение относитс к машиностроению , к способам испьп зни изделий , а именно к измерению суммарного объема открытых пор.The invention relates to mechanical engineering, to methods of using products, namely to measuring the total volume of open pores.
Цель изобретени повьшение точности измерений путем учета всех открытых пор.The purpose of the invention is to increase the measurement accuracy by taking into account all open pores.
Способ осуществл ют следующим образом .The method is carried out as follows.
Вьйирают тонкие подложку из того же материала, что и напыл емое изделие . Подвергают ее обезжириванию,пескоструйной обработке и определ ют ее массу т , Накладывают подложку на изделие, после чего напыл ют на него покрытие. Отслаивают покрытие от изделий вместе с подложкой и определ ют массу mj покрыти с подложкой,После чего пропитьшают покрытие с подложкой в жидкой среде в течение 3 ч и определ ют массу т подложки с покрытием в жидкости. Затем определ ют массу т подложки с покрытием после пропитки в воздухе. А открытую пористость покрыти определ ют по формулеThin substrates are made of the same material as the sprayed product. It is subjected to degreasing, sandblasting and its mass is determined, the substrate is placed on the product, after which a coating is deposited on it. The coating from the products together with the substrate is peeled off and the mass mj of the coating with the substrate is determined, and then the coating with the substrate is passed through in a liquid medium for 3 hours and the mass of coated substrates is determined in a liquid. The mass of coated substrates is then determined after impregnation in air. And the open porosity of the coating is determined by the formula
