METHOD OF DETERMINING MICROHARDNESS |
| 摘要 |
FIELD: physics. ^ SUBSTANCE: microsection is prepared. A mechanical imprint is made on the surface of the microsection and the size of the imprint is measured using a microscope. Imprints are made by solid particles in a liquid and having gained high acceleration which is excited by an ultrasonic head in the pre-cavitation region. ^ EFFECT: possibility of determining microhardness of materials in arbitrary units, having a microcrystalline structure or thin coatings. ^ 4 cl, 1 dwg |
