Progressive Tribology Mapping of Flooring
The traffic of human movement, movement of furniture, and other daily activities imposes constant degradation onto flooring. Flooring, usually comprised of wood, ceramic, or stone, must be able to handle the wear and tear they are designed for, whether residential or commercial applications. For this reason, most flooring have a layer that is supposed to be resistant to wear called a wear layer. The thickness and durability of the wear layer will depend on the type of flooring and the amount of foot traffic it will be receiving. Since flooring can have multiple layers (e.g. UV-coating, wear layer, decorative layer, glaze, and etc.), the wear rate through each layer can be very different. With Nanovea T2000 Tribometer with a 3D Non-Contact Line Sensor attachment, the progression of wear on a stone and wood flooring is closely observed.
Adhesiveness of Tape via Nanoindentation
The effectiveness of tape is determined by its cohesive and adhesive abilities. Cohesion is defined as the tape’s internal strength while adhesion is the tape’s ability to bond to its interacting surface. The adhesion of tape is influenced by numerous factors, such as exerted pressure, surface energy, molecular forces, and surface texture [1]. To quantify adhesion of tapes, nanoindentation with the Nanovea Mechanical Tester’s Nano Module can be conducted to measure the work required to separate the indenter from the tape.
