In terms of the positive characteristics of the portable ultrasonic solid state MET-Y1 in our company it should be noted its use in dispersing finished parts without breaking the surface, measurement of hardness in hard-to-reach areas, bulk dies, large-sized parts.

NPP «Linetron-Nizhny Novgorod» is engaged in the development and implementation of hardening technologies on the basis of beam-pulsed exposure to carbon ions. Currently, we specialize in processing powerful ion beams (IIP) cutting carbide tool railway nomenclature.

One of the most important indicators of the physical and mechanical properties of solid alloys is the hardness of HRA, which is strictly regulated. Therefore, during the input control of carbide tools purchased from manufacturers, we were acutely faced with the issue of determining the solidity and establishing its compliance with the requirements of regulatory documentation (GOST, TU).

Measurements on conventional hard domers with high loads (on the indent) often do not justify, because, as a rule, are carried out on sample-witnesses, have a significant depth of penetration (visible footprint) and characterize the hardness of the main material. The hardness in the working area of carbide plates can differ significantly (due to mechanical, thermal and different types of surface treatments) from the base material.

Having a positive experience with the solid state ultrasonic MET-Y1, developed by you for metals and alloys, we applied to the Physical and Mechanical Measurement Center "MET" to develop software for working with solid alloys of different brands.

Thank you for successfully solving the problem. The device is used by us in the input control of the hard-alloy tool, in the measurement of HRA solid alloys after various heat treatment modes, as well as in the output control of the tool reinforced with powerful ion beams. Due to the low indentation depth, your instrument is very informative for determining the solidity of hardened surface layers (both with IIP and with various types of chemical-thermal treatments).

The portability, speed of measurements and the absence of a visible fingerprint make it indispensable for measurements on the finished instrument, as well as on parts in different assemblies and equipment. Your device has proven itself in the control of the hardness of railway bearings, blades of gas turbine engines. We hope for further cooperation and thank you for the free verification after the first year of operation of the device.
