Portable Profilometer

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 Nanoindentation

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.

Fretting Wear

Fretting Wear Evaluation Using Tribometer

Fretting wear is “A special wear process that occurs at the contact area between two materials under load and subject to minute relative motion by vibration or some other force.” When machines are in operation, vibrations inevitably occur in joints that are bolted or pinned, between components that are not intended to move, and in oscillating couplings and bearings. The amplitude of such relative sliding motion is often in the order from micrometers to millimeters. Such repetitive low-amplitude motion causes serious localized mechanical wear and material transfer at the surface, which may lead to reduced production efficiency, machine performance or even damage to the machine.

Texture Luster

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.
