SOLVER Pipe II for Non-Destructive AFM

SOLVER Pipe II is an atomic force microscope that can be used in industrial settings to perform in situ, non-destructive testing.

Purpose

In various industrial plants, prediction and early warning of the degradation of engineering materials used in severe conditions is a high priority activity. The potential to conduct diagnostics on the metalwork in a plant without going offline is specifically of utmost importance to industries in the processing, energy, and other sectors.

The existing diagnostic devices can find out degradation in operational pipework and related equipment only after its condition has already worsened to a dangerous stage of deterioration. SOLVER Pipe is an innovative, high-precision, and reliable diagnostic system that enables plant managers to be better able to reduce risks and accomplish incident-free operation through scheduled maintenance and anticipatory control of materials and equipment used in their industrial facilities.

Benefits

With the use of atomic force microscopy (AFM), SOLVER Pipe has several key benefits over other advanced diagnostic techniques:

  • Benefits over optical microscopy — can image the materials’ structure at a wide array of magnification levels from micro- to nano-scale
  • Benefits over electron microscopy: inexpensive, compact, and eliminates the need for complex vacuum technology
  • The equipment performs imaging at a broad range of magnifications while staying online, thus more comprehensive information related to the material surface can be obtained than data acquired using alternative techniques. It is possible to carry out simultaneous measurement of the material’s hardness in the analyzed area.
  • The generated AFM image is a digital matrix from which statistical/mathematical information and quantified characteristics can be extracted. The digital image also allows the use of pattern recognition algorithms for automatically identifying the defects. This not only offers important diagnostic information to plant managers for their operational planning but also creates new possibilities for ascertaining the characteristics that cause the degradation of the operational life of the materials.

Operation

In combination with the latest Nova PX data processing software and the PX Ultra controller, NEXT offers the most comprehensive suite of AFM and STM techniques for beginners as well as advanced users. NEXT offers more than 60 modes and techniques in basic configuration.

Flexible, easy-to-use software

The smart algorithms and predefined settings in the SOLVER Pipe software enable fast configuration and operation in all advanced modes. The software carries out processing, measuring, and presentation of results with visibility of all captured data and high information content.

Electrical studies

SOLVER Pipe provides users with a broad range of electric measurement methods, such as Kelvin Probe Force Microscopy with phase or amplitude modulation, Electrostatic Force Microscopy with frequency and amplitude modulation, Piezoresponse Force Microscopy, and Spreading Resistance Imaging.

Topography measurements

In order to carry out topography measurements, amplitude modulation, contact, HybriD mode AFM, and frequency modulation techniques can be used.

Nanomechanics

An added feature of the SOLVER Pipe is the ability to perform nano-mechanical measurements. Specifically, Pipe SOLVER enables the numerical values of Young’s modulus to be obtained using standard AFM cantilevers.

Magnetic properties

SOLVER Pipe can be used to carry out MFM measurements by using line-by-line, two-pass technique, and frame-by-frame analyses.

Data Analysis

Using the SOLVER Pipe advanced software, the user can analyze the obtained data and present it in a form appropriate for practical use by an expert in-house technician. Digital images can be analyzed in an automated manner, thus providing the structural characteristics of the tested materials, such as the potential to select grains and pores and to develop images of extended objects.

The condition and suitability of the material for further operation can be exactly predicted using the images produced by SOLVER Pipe. The presented information includes distribution of grains by size, the grain and state boundaries, and pore distribution analysis (by size, volume, and area). The system also generated optical images of high magnification, thereby enabling simultaneous comparison with the acquired AFM data.
