METHOD OF NONDESTRUCTIVE TESTING OF SURFACE

摘要

FIELD: measurement of physical parameters and condition of surface object. SUBSTANCE: method involves action on surface of object with optical emission in the form of strip with length 1 and width 2a, movement of strip over surface of object and recording of temperature in front of strip while it is moved to distance d = c * a, where c is coefficient laying within limits 1-2. Temperature measurement may be conducted at different distances from center of strip laying within range a
