Jr25 Portable Profilometer Gets New Design!
The Jr25 is the first truly portable high performance Profilometer of its kind. With an optional battery pack and carrying case, the Jr25 provides measurement capability during field studies. To enhance user convenience and control the entire portable profilometer frame has been extended as gripping handles.
Metallurgy Study of Multiphase Material Using Nanoindentation
Metallurgy studies the physical and chemical behavior of metallic elements, as well as their intermetallic compounds and alloys. Metals undergoing working processes, such as casting, forging, rolling, extrusion and machining, etc., change their phases, microstructure and texture, which results in varied physical properties including hardness, strength, toughness, ductility, and wear resistance. Metallography is often applied to learn the formation mechanism of such specific phases, microstructure and texture.

Anodized Aluminum Surface Texture Effect On Luster
Anodizing is an electrolytic passivation process commonly applied to convert aluminum to aluminum oxide. It can modify the surface texture and changes the microstructure of the metal near the surface. Such an anodized aluminum oxide layer is generally much stronger and more adherent than most types of paint and metal plating. It can significantly enhance corrosion and wear resistance and improve cosmetic effects of the products. Anodized aluminum is widely used on electronic devices and consumer products, such as cell phones, cameras, mp3 players and many others.

Gold Coating Adhesion on Quartz Crystal Substrate
As an extremely accurate device, the Quartz Crystal Microbalance (QCM) measures the mass change down to 0.1 nanogram. Any mass loss or delamination of the electrodes on the quartz plate will be detected by the quartz crystal and cause significant measurement errors. As a result, the intrinsic quality of the electrode gold coating and the interfacial integrity of the coating/substrate system play an essential role in performing accurate and repeatable mass measurement. The Micro scratch test is a widely used comparative measurement to evaluate the relative cohesion or adhesion properties of coatings based on comparison of the critical loads at which failures appear. It is a superior tool for reliable quality control of QCMs.

Reliable quality control heavily relies upon accurate, quantifiable and reproducible surface inspection. Flatness & finish of the Quartz Crystal Microbalance (QCM) surface are vital to its accuracy and both measurements in 3D guarantees proper manufacture processing and control measures. Unlike a touch probe technique, the Nanovea Perfilómetro performs a 3D non-contact surface measurement of the sample. This eliminates the risk of creating micro scratches on the QCM surface that may cause inaccuracy or errors in the mass measurement.

The QCM works based on the piezoelectric properties of the quartz crystal. It measures the mass change on the surface down to 0.1 nanogram during material deposition by detecting variations in the resonance frequency of the crystal. Due to the extreme sensitive and accurate characteristics of the QCM, it is critical to ensure that the two electrodes on both sides of the quartz plate possess good wear resistance. Any mass loss on the metal electrodes caused by wear can lead to significant error in the measurement. Therefore, reliable and accurate wear evaluation using a Tribómetro is important for quality control and R&D of QCMs.
