Equipment and facilities available to the LNWM are described below. In addition, SEM, TEM, and EDS is available in the College of Engineering and Applied Sciences microscopy user facility.

Facilities

The NT-MDT scanning probe microscope is used for nanotribology research with capabilities to perform topography, force modulation, phase imaging, lateral force microscopy, and acoustic force atomic microscopy in air and liquid environments. The instrument has a 10x10m and 100x100m scanners both with closed-loop control.

SolverPro-M Atomic Force Microscope (NT-MDT)

The 2kN testing frame can be used for either compressive or tensile testing of specimens, as well as Double-Cantilever Beam delamination testing. Data-acquisition is performed through a high-speed DAQ board to obtain load and proximity signals. A 0.5kN frame (TIRAtest 26005) is also in the lab.

2kN Materials Testing Frame (TIRAtest 2602)

The microscope has an 18 million pixel CCD resolution and optics ranging from 20-5000X, which gives a visible region at highest magnification of 40m x 60m. Flexible lens positioning, 3D surface topography reconstruction, and real-time imaging make this instrument ideal for tribology and biological applications.

Digital Microscope (Keyence VHX-500)

The Ecomet polisher is used for the preparation of samples for AFM and nanoindentation characterization, and SEM analysis. The system has variable speeds and liquid flow rates. The polisher is also used for fabrication of custom indentation tips.

Laboratory for Nanotribology and Wear Mechanics

State University of New York at Stony Brook

The Wilson hardness tester is used for measurement of material hardness of samples when a microscopic hardness value is needed. The instrument has capabilities for Rockwell hardness measurement as well as other commonly used scales.

Model 523R Rockwell Hardness Tester (Wilson)

A Micro Materials NanoTest instrumented indenter is housed in the Department of Mechanical Engineering and is used for indentation, scratch testing, and friction measurements. A custom-built friction sensing wet cell is used for tribological and materials characterization in aqueous environments.

Nano- and Microindenter (Micro Materials)

The Fullam loading stage is utilized for mechanical testing of small specimens, and may be used beneath the light microscope. Tensile and compressive loading with load cells of 10N and 4.5kN is possible over small displacements.

Fullam Loading Stage (MTII/Fullam)

Three environmental chambers are housed in the Department of Mechanical Engineering and are used for exposure of bulk and coating materials to Hygrothermal conditions, Combined UV-Moisture, and Salt-Spray Liquid. They are ideal for testing longevity of Composites and Coatings.
