Creep Deformation of Polymers by Nanoindentation

Creep deformation often occurs due to the lack of alertness of the time-dependent creep behavior of the polymer materials used under specific service conditions. As a result, it is important to develop a reliable and quantitative test of the viscoelastic mechanical behaviors of the polymers. Nanoindentation using the Nanovea Mechanical Tester applies the load by a high-precision piezo and directly measures the evolution of force and displacement in situ. The combination of accuracy and repeatability makes it an ideal tool for creep measurement.

Tribology of Polymers by Tribometer

Tribology of Polymers are commonly seen for tribological applications, such as tires, bearings and conveyor belts. Different wear mechanisms occur depending on the mechanical properties of the polymer, the contact conditions, and the properties of the debris or transfer film formed during the wear process. In order to ensure that the polymers possess sufficient wear resistance under the service conditions, reliable and quantifiable tribological evaluation is in need. It allows us to quantitatively compare the wear behaviors of different polymers in a controlled and monitored manner and to select the best candidate for the target application. The Nanovea Tribometer offers repeatable wear and friction testing using ISO and ASTM compliant rotative and linear modes, with optional high temperature wear and lubrication modules available in one pre-integrated system. This unmatched range allows users to simulate different work environment of the polymers including concentrated stress, wear and high temperature, etc.

Transparent Film Thickness by 3D Non Contact Profilometry

Transparent film thickness and uniformity is critical for product quality and performance. For example, in CD, DVD and Blu-Ray Disc (BO) production, precise control of the thickness and uniformity of the transparent cover and space layers plays an important role in avoiding focus errors of the laser. Improper injection molding process during CD and BO production may lead to stress-induced birefringence and unreliable data reading. An accurate thickness measurement of the transparent film ensures reliable product inspection and quality control.

Glass Coating Humidity Wear Testing By Tribometer

A major application of the self-cleaning coating is the exterior surface of the glass facade on skyscrapers. The glass surface is often attacked by high-speed particles carried by strong winds. The weather condition also plays a major role in the service lifetime of the glass coating. It can be very difficult and costly to surface treat the glass and apply the new coating when the old one fails. Therefore, the wear resistance of the glass coating under different weather condition is critical. In order to simulate the realistic environmental conditions of the self-cleaning coating in different weather, repeatable wear evaluation in a controlled and monitored humidity is in need. It allows users to properly compare the wear resistance of the self-cleaning coatings exposed to different humidity and to select the best candidate for the targeted application.

Self Cleaning Glass Coating Friction Measurement

Self cleaning glass coating possesses a low surface energy that repels both water and oils. Such a coating creates an easy-clean and non-stick glass surface that protects it against grime, dirt and staining.  The easy-clean coating substantially cuts the water and energy usage on glass cleaning. It does not require harsh and toxic chemical detergents, making it an eco-friendly choice for a wide variety of residential and commercial applications, such as mirrors, shower glasses, windows and windshields.

Corrosion Effect On Hardness Using Nanoindentation

The mechanical properties of materials deteriorate during the corrosion process. For example, lepidocrocite (γ-FeOOH) and goethite (α-FeOOH) form in the atmospheric corrosion of carbon steel. Their loose and porous nature results in absorption of moisture and in turn further acceleration of the corrosion process. Akaganeite (β-FeOOH), another form of iron
oxyhydroxide, is generated on the steel surface in chloride containing environments. Nanoindentation can control the indentation depth in the range of nanometers and microns, making it possible to quantitatively measure the hardness and Young’s modulus of the corrosion products formed on the metal surface. It provides physicochemical insight in corrosion mechanisms involved so as to select the best candidate material for the target applications.

Drywall Texture & Pitting Using 3D Profilometry

Drywall texture and roughness is critical in the final products quality and appearance. A better understanding of the effect of surface texture and consistency on the moisture resistance of the coated drywall allows selecting the finest product and optimizing the painting technique to obtain the best result. Quantifiable, fast and reliable surface inspection of the coating surface is in need for quantitative evaluation of the surface quality. The Nanovea 3D Non-Contact Profilometers utilizes chromatic confocal technology with unique capability to precisely measure the sample surface. The line-sensor technique can finish scanning a large drywall surface in minutes.
