1 Tescan LYRA-3 Model XMU FIB-FESEM Scanning Electron Microscope (SEM) with Focused Ion Beam (FIB) capability and a Transmission Electron Microscope (STEM) detector. The FIB can perform cross sectioning of materials to examine subsurface features. High-resolution STEM reaches the nanometer scale such as the oxide film protecting metals from corrosion. NCERCAMP at the University of Akron Major Equipment Hitachi TM EDS This Tabletop Microscope offers high resolution imaging without the need of sample preparation. It is user friendly, compact, and portable. It is capable of performing imaging and quantitative analysis on metals, composites, and organic materials such as polymers, wood, and biological materials. Alicona InFocus G5 Microscope Highly accurate, fast, and flexible optical 3-D measurement system. This instrument obtains surface and sub-surface imaging of materials, performs roughness measurements, and identifies different components and phases inside solid materials. Bruker Multimode 8 Atomic Force Microscope with Nano Scope V Superior resolution, performance, and image optimization for fluid environments. This instrument performs rapidly direct mapping of nanomechanical properties such as elastic modulus, adhesion, and dissipation in doped materials. It can work in air and liquid temperature ranges of -35 C to 100 C.

2 Olympus BX63 Fluorescence Microscope This microscope produces fluorescence images with bright colors and dark backgrounds to analyze pigment dispersion in coatings. Uniform illumination and detection is achieved through the use of high transmission objectives, mirror units, and a fly-eye lens system. PAR/VersaSCAN Electrochemical Scanning System This single platform includes Scanning Electrochemical Microscopy (SCEM), Scanning Vibrating Electrode Technique (SVET), Scanning Kelvin Probe (SKP), Localized Electrochemical Impedance Spectroscopy (LEIS), and Scanning Droplet System (SDS). Plotting recorded parameters versus probe position creates a map that can represent local electrochemical current, impedance, relative work function, or topography. Q-Lab SSP-1100 (1) and CCT-1100 (3) Salt Spray Chambers (Q-Fog) Salt spray chambers expose coated and uncoated panels to aggressive environments in order to accelerate corrosion damage. The chambers ensure thermal, chemical, and physical stability of the enclosed environment. The SSP-1100 maintains low-humidity conditions by forcing room air over specimens and the CCT-1100 chambers maintain % humidity. Q-Lab Accelerated Weathering Tester (QUV) The QUV gives NCERCAMP investigators the ability to reproduce the damaging effects of sunlight. This instrument uses two types of UV lamps depending on the exposition to the UV that is required. Investigators can alternate cycles of wetness and UV exposure using fitted spray systems to simulate dew and rain. Temperature, test time, irradiance, and water level can be set according to user s needs.

3 Q-Lab Condensation Tester (QCT) The condensation tester allows NCERCAMP researchers to simulate the damaging effects of outdoor moisture attack by condensing warm water directly onto the test specimen. The chamber creates 100% humidity to simulate and accelerate damage caused by rain and dew, replacing water immersion and non-condensing humidity tests. This machine is capable of continuous humidity or wet/dry cycles. High Temperature Burner Rig This equipment simulates high temperature gas turbine engine environments that include high stresses, high temperatures, high pressures, and ingested species. The burner rig allows researchers to test materials, especially ceramic matrix composites, with and without environmental barrier coatings (EBC) as well as super-alloys with TBC/EBC coatings under more extreme conditions including more severe corrosive environments. Tukon Microhardness Tester This equipment allows NCERCAMP researchers to test the hardness of a material or coating. It is equipped with a threeposition turret which includes one indenter position as well as a 10x and 50x objective for single scale microhardness testing. For more demanding applications, the indenter is equipped with a six position turret, including two indenter positions as well as 5x, 10x, and 50x long working distance objectives CorTest Recirculating HT/HP Autoclave US nuclear power plants in operation are reaching their design limit. Challenges in their maintenance include issues such as predicting stress corrosion cracking and deposition of activated corrosion products onto the surfaces of stainless steel or nickel base alloys. This autoclave simulates the temperature, pressure, chemistry, and operating stresses that are experienced in pressurized water reactor systems.

4 PHI 710 Scanning Auger Nanoprobe This equipment offers high resolution SEM imaging, auger elemental analysis, and high spatial resolution elemental imaging. Applications include surface analysis of metal, metal oxide and coating-metal interfaces, imaging analysis of how corrosion proceeds from a pinhole or scratch, and chemical mapping of wear in alloys, multilayers and in tribological applications. Accurion EP4 Imaging Ellipsometer The ellipsometer offers high contrast images of the sample, ellipsometry with lateral resolution as small as one micron, and lateral resolution independent of illumination spot size. These capabilities allow NCERCAMP researches to study the structures of metal oxide multilayers and organic coatings, wear of coatings, changes in coatings with exposure to humidity and environmental changes, liquid/liquid interfaces, and adsorption of surface active molecules. Hysitron Premier Nanoindenter/Nanoscratch This instrument is designed to quantitatively measure the mechanical properties of small volumes of material. The hardness of materials is measured by pressing a nanoindentation probe into the surface of a material and measuring the relationship between applied probe force and the resulting probe displacement. In addition, this technique enables elastic modulus, creep, stress relaxation, interfacial adhesion, and fracture toughness characterization. NEXDEP Thin Film Deposition System This deposition system provides a versatile chamber for depositions of metal, metal oxides, and some ceramic films for corrosion studies. Applications include deposition for corrosion studies, studies of interfacial interactions, protective polymer coatings, and metallic contact layers for thin film devices, such as OLEDs, solar cells, and thin-film transistors.

5 Nikon XT H 320 CT This CT features a multi-voltage X-ray source that is able to run highly accurate inspection on dense materials such as metals and is equipped with a large walk-in cabinet to accommodate large samples. This instrument provides high resolution imaging of materials, including polymers and ceramics, allowing NCERCAMP investigators to characterize corrosion-related damage, fracture surfaces, inclusions, corrosion products, and grain structures. MTS Landmark Testing Systems (3) These servohydraulic load frames allow researchers to perform tension and compression testing on materials including plastics, elastomers, composites, and metals for prototyping and experimental validation of modeling. Full and standalone systems include load frame, controller, software, grips and fixtures, environmental simulation capabilities, extensometers, and hydraulic power units.
