Method and the device for testing resistance of material surfaces and their coatings to scratching, preferably with high resistance to abrasive wear

摘要

how is the rysikiem features (1) on the test specimen (2) material with coating or no coating, at least one of the rysika in one direction, and then the test result on the basis of geometrical features (1), which is the function of a sample (2), the pressure force on the the point and speed its displacement relative to the test sample (2).as the point is used u015bcierniwo (3) selected parameters of abrasive to the sample (2) and (3) as u015bcierniwo shall apply a single test sample (2).in the implementation of the features (1) u015bcierniwo (3) is fixed, and a sample (2) moving the posuwisto turning to abrasives (3), and in addition, when the features (1) applies diversified, advantageously smooth adjustable and variable in time relative speed sample (2) and (3) and differentiated, abrasivesbeneficial smoothly adjustable and variable during the clamping strength abrasives (3) to the sample (2). the object of the application is to use this method and device. the declaration is applicable, especially to study resistance to delineate the surface of materials or coatings u015bcierniwem (3) as a single grains of the abrasive material.
