Mark producing method for titanium coating of sample during hardness test, involves terminating pressing process before expiry of application time based on result of comparison of characteristics of analyzed behaviors with threshold value

摘要

The method involves pressing a penetrator (15) in a surface of a sample (14) with a constant, defined testing force during application time. Penetration behaviors of the penetrator are analyzed over a time interval after expiry of another time interval, which is shorter than application time. Characteristics of the analyzed behaviors are compared with a threshold value during and/or after the expiry of the former time interval. The pressing process of the penetrator is terminated before expiry of the application time based on the result of the comparison. An independent claim is also included for a device for producing a mark in a surface of a sample comprising a controlling and evaluating device for controlling a drive motor.
