Shot Peen Hardness With Nanoindentation
Submitted by NANOVEA on Thu, 2011-11-17 05:03.The intention of shot peening is ultimately to alter the mechanical properties of a given surface. By hitting the surface with controlled shot the surface will deform plastically. Proper Instrumentation will play a vital factor in achieving reliable and intended results.

Shot Peened Surface Characterization Using 3D Metrology
Submitted by NANOVEA on Wed, 2011-10-12 18:29.
Shot peening is a process by which a substrate is impacted with round metal, glass or ceramic beads, also known as shot, at a force intended to create plasticity on the surface. The characteristics present prior to and after the peening process provides vital information to better the understanding and control of the process. Among many others, surface roughness and dimple coverage area left by the shot, are of particular interest.
Viscoelastic Analysis With Nanoindentation DMA
Submitted by NANOVEA on Tue, 2011-10-11 17:11.Viscoelasticity can be studied using Dynamic Mechanical Analysis (DMA) during Nanoindentation. By applying controlled oscillatory stress the resulting strain can easily be measured. An elastic material will have stress and strain in phase while a viscous-elastic material will have strain lagging stress. In many applications during quality control and R&D, it is important to reliably test this behavior. For example, polymer coatings, like that found on solar panels and medical devices, need to be studied by DMA Nanoindentation to understand the transition between viscous and elastic properties.

Microindentation Mapping With Acoustic Emission On Glass
Submitted by NANOVEA on Fri, 2011-09-16 02:11.Hardness mapping has been widely used to assess the variation of mechanical properties across a large surface area. However, with the study of applications such as glass it is the crack initiation that is of particular interest. It is for this reason that acoustic emission can be used during the mapping of indents to not only map hardness but also map the crack initiation values over the surface area. Using acoustic emission proves to be a critical tool during the study of applications where micro fracture is of primary concern.
Stribeck Curve Analysis Using Tribometer
Submitted by NANOVEA on Wed, 2011-08-17 21:16.When lubrication is applied to reduce the wear/friction of moving surfaces an increasing load can shift the lubrication from several regimes such as Boundary, Mixed and Hydrodynamic Lubrication. The fluid viscosity, the load that is carried by the two surfaces and the speed that the two surfaces move relative to each other combine to determine the thickness of the fluid film. It is this process that determines the lubrication regime. How the regimes react to friction is shown in what is called a Stribeck curve. To evaluate lubricants, and their reaction with applications the Stribeck Curve can be identified using a Pin On Disk Tribometer.

Fractography Analysis Using 3D Metrology
Submitted by NANOVEA on Tue, 2011-06-14 18:12.Fractography is the study of features examined on fracture surfaces and has historically been investigated via Microscope or SEM. Microscope being used for macro scale analysis and SEM particularly when it is the nano or microstructure that is vital to the analysis. Both ultimately allowing for the identification of the fracture mechanism type. Although effective, the Microscope clearly has its limitations and the SEM in most cases, other than atomic level analysis, is unpractical for fracture surface measurement and lacks broad use.
Nanoindentation Fracture Toughness
Submitted by NANOVEA on Tue, 2011-06-14 18:10.The ability of a material to resist cracking, or fracture, has been vital to the studies of fracture mechanics. Until recently the study of fracture toughness has been analyzed at a macro range using powerful instrumentation applied to large samples. Now using the precise capability of a Nanoindentation system, among many other properties, fracture toughness can be studied with a safe and user friendly system on small and localized areas of samples.http://www.nanovea.com/Application%20Notes/nanofracturetoughness.pdf
Nanoindentation Creep Measurement
Submitted by NANOVEA on Mon, 2011-05-16 17:39.Creep can be characterized as the result of a solid material that is slowly and permanently deformed under the influence of stress. Deformation results from the consistent stress below the yield strength of the material. The amount of applied stress and its duration can eventually lead to the failure of the given material. Ultimately, it is for this reason that Creep measurement provides crucial information to study material behavior. More importantly, nano & micro advances with materials require mechanical characterization unattainable through traditional Creep measurement methods intended for largebulk materials.
Instrumented Indentation, It's More Than Hardness
Submitted by NANOVEA on Fri, 2011-05-13 17:07.As the validity of Instrumented Indentation continues to expand throughout all materials research, many throughout the community are still unclear as to what exactly can be achieved. Although advances in technology will continue to grow the list of capabilities of Instrumented Indentation, we will review a list of what can be expected as of now. But first lets quickly review how Instrumented Indentation works.
Cyclical Nanoindentation Stress-Strain Measurement
Submitted by NANOVEA on Thu, 2011-04-14 20:49.The Stress-Strain curve obtained by Nanoindentation reveals the correlation of "Stress" and"Strain" of a given material under nano controlled loads. Unlike the traditional Tensile Testing method of obtaining Stress-Strain curve data, which gives data at a macro level, the Nanoindentation method provides vital Stress-Strain curve data at nano level scale without the large and intense machinery. The Stress-Strain curve of various materials will vary widely. Ultimately, the Stress-Strain curve provides crucial information on the threshold between elastic and plastic-elastic behavior zone as the sample is subject to increasing loads.
Microindentation & Fracture of Mineral Rock
Submitted by NANOVEA on Mon, 2011-03-14 22:07.The use of Microindentation has proven to be a crucial tool for rock mechanics related studies. For example, Microindentation has been used to advance studies in excavation by allowing further understanding of rock mass properties and its separation. Microindentation has been used to advance drilling studies to improve drill heads and improve drilling procedures. Microindentation has also been used to study chalk and powder formation from minerals. With the use of Microindentation studies can include Hardness, Young’s Modulus, Creep, Stress-Strain, Fracture Toughness, Compression and others with a single instrument.
Paper Roughness Measurement With 3D Metrology
Submitted by NANOVEA on Mon, 2011-03-14 22:04.Paper surface topography is vital to the intended use and quality of the product. To control paper product quality it will heavily rely upon quantifiable, reproducible and reliable surface measurement. Precise surface measurement and evaluation of a paper product can lead to the best selection of processing and control measures. The Nanovea 3D Non-Contact Profilometers utilize chromatic confocal technology with unmatched capability to measure paper surfaces. Where other techniques fail to provide reliable data, due to probe contact, surface variation, angle and reflectivity, Nanovea Profilometers succeed.

Using Nano Scratch Testing For Composite Failure
Submitted by NANOVEA on Tue, 2011-02-15 23:42.One of the major concerns for composite material is it’s durability in final form. The size of particles that form the strengthening additive can drastically affect the overall final performance of the composite material. By using the nano scratch testing method the failure of composite material can be compared to identify the most durable formula.

The Importance of 3D Metrology & AFM Integration
Submitted by NANOVEA on Tue, 2011-01-11 22:26.
To ensure the quality levels of applications spanning across nearly all industries, most R&D units have or are in the process of obtaining or updating their instruments to include surface measurement at various range. This would ensue before an exhausting list of instrument
options would have to be comparatively matched to fit user specific measurement requirements. Once the instrument is selected, it is only later that the user then identifies that their chosen instrument is not capable of broad and or expandable measurement use. It is
unfortunate that only at this point most recognize the true value of a single surface measurement instrument with broad capability from Macro through Angstrom range.
