摘要： The present invention provides a hardness tester capable of accurately detecting a point where an indenter contacts a sample in instrumented indentation testing. Prior to beginning measurement, the hardness tester defines an expected range for a value for a displacement, speed, or acceleration of an indenter during a process of approaching a sample. After measurement has begun, the hardness tester measures the value for the displacement, speed, or acceleration of the indenter during the process of approaching the sample. When the measured value is not within the expected range, the hardness tester determines that detection of a zero point has failed.

摘要： A hardness tester forms an indentation on a surface of a sample by loading a predetermined test force with an indenter and measures a hardness of the sample using the indentation. The hardness tester includes a light source emitting light on the surface of the sample and forming an illumination pattern having a spot; and a controller forming the indentation by bringing the indenter into contact with the sample in a state where a perpendicular line of a vertex of the indenter overlaps a test point when the position of the spot of the illumination pattern formed by the light source on the surface of the sample is used as the test point.

摘要： The hardness tester includes a plurality of weights; a transmission mechanism transmitting to an indenter a force of gravity acting on the weights; and a test force switching mechanism switching between magnitudes of a test force. The weights include hollow portions running through the weights in a vertical direction; and accommodation portions formed so as to be capable of accommodating the weight directly below. Outside tapered portions are provided to an exterior surface of the weights and inside tapered portions are provided to an interior surface of the accommodation portions. The transmission mechanism includes a shaft member and a weight engagement portion capable of being accommodated by the bottom-most accommodation portion to engage a weight. The weight engagement portion includes a tapered portion engaging the weight to regulate horizontal-direction displacement. A predetermined gap is reserved between the hollow portions and the shaft member.

摘要： Indentation tester capable of adjusting vertical-direction positioning drift due to individual differences of an indenter when indenters are switched includes an adjustment mechanism. The adjustment mechanism adjusts relative vertical-direction positions of a displacement sensor movable portion and a displacement sensor fixed portion. The adjustment mechanism includes a first hollow disk having a spiraling surface formed on a bottom surface; and a second hollow disk having a spiraling surface formed on a top surface. The spiraling surface of the second hollow disk has a thread equal to that of the spiraling surface of the first hollow disk. The first hollow disk rests on the second hollow disk such that the bottom surface of the first hollow disk is overlaid on the top surface of the second hollow disk. The first hollow disk and the second hollow disk are capable of rotation on a center axis of an indenter column.
