Optoelectronic Film Inspection Using 3D Profilometry

Optoelectronic film devices and systems convert visible or infrared radiation to electrical signals. Thin-film optoelectronic devices have a wide variety of applications, including photocells, solar cells and LEDs, etc. The continual development of the optoelectronic thin films and the associated technologies such as impurity incorporation, etching and surface chemistry aims for improving the photoconversion at micro or nano scale levels.

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.

Machining Finish Quality Using 3D Profilometry

Machining finish is a result of different cutting techniques exhibiting different surface features. Flatness, roughness and texture of a cut/machined surface is vital to its end use. Accurate clean cut reduces the further work on grinding and rough edge removal. For example, when marble tiles are manufactured, inaccurate and rough cutting may lead to mismatch during the tile floor installation.  Quantitative measurement of the surface texture, consistency, roughness and others is critical in improving the cutting/machining processing and quality control measures.

Grooved Stent Coating Failure Using Nano Scratch Testing

Drug–eluting stent is a novel approach in stent technology. It possesses a biodegradable and biocompatible polymer coating that releases medicine slowly and continuously at the local artery to inhibit intimal thickening and prevent the artery from being blocked again. One of the major concerns is the delamination of the polymer coating that carries the drug-eluting layer from the metal stent substrate. In order to improve the adhesion of this coating to the substrate, the stent is designed in different shapes. Specifically in this study, the polymer coating locates at the bottom of the groove on the mesh wire, which brings enormous challenge to the adhesion measurement. A reliable technique is in need to quantitatively measure the interfacial strength between the polymer coating and the metal substrate. The special shape and the small diameter of the stent mesh (comparable to a human hair) require ultrafine X-Y lateral accuracy to locate the test position and proper control and measurement of the load and depth during the test.
