Wear measurement of the cutting edge of superhard turning tools using TLA technique

High-Speed Sharpening and Thermo-activated Refinement of Blade Tools from Synthetic Diamonds

“…above 180 m/s, diamond grains are not abraded, but instead, micro-cracks are occurring, forming sharp micro and submicron cutting edges, leading that way in reduced cutting forces [21,23]. Moreover, increased peripheral grinding speed results to lower wear rate of the abrasive working surface of the wheel (WSW), while improved machined surface quality can be achieved, as lower cutting forces are developed [26]. The current paper presents a study regarding the sharpening and thermo-activated refinement of blade tools, aiming in increased productivity, and higher machined surface quality.…”

Homogeneous near surface activity distribution by double energy activation for TLA

“…The depth calibration procedure [4] varies in accordance with the activation. If the activation depth is in the range of several tens of micrometers, the depth profile of the radioactive nuclei can be determined by using the stacked foil technique [8][9][10].…”

“…Besides the conventional processes, nuclear methods are also used for this purpose [1][2][3][4][5][6][7]. TLA is one of the applications, in which the requirement of a constant activity-depth profile over a relatively large area can occur.…”

Wear measurement using radioactive tracer technique based on proton, deuteron and α-particle induced nuclear reactions on molybdenum

“…In the history of nuclear wear measurement the radioisotopes of cobalt ( 57 Co and 56 Co) mainly produced from Fe by proton and deuteron irradiations are the most widely used nuclear tracers [6][7][8][9][10][11][12][13]. Their half-lives, gamma-energies, and production yields are very suitable to perform wear measurement.…”
