Identifying Cohesive Failure of Screen Protectors with Acoustic Emission

In today’s age of information, handheld electronic devices are extremely common amongst consumers.  These portable multifunctional devices, however, can be quite expensive. To protect the fragile components, such as the glass interface, screen protectors can be used. How effective are the screen protectors? Using Nanovea’s Mechanical Tester’s Micro Module with an acoustic emission attachment, we can clearly identify critical loads at which the screen protector fails.

Corrosion Resistance of Coating After Scratch Testing

The corrosion resistant coatings should possess sufficient mechanical strength as they are often exposed to abrasive and erosive application environments. For example, the abrasive oil sands constantly wear away the inside of pipe, which progressively compromise the pipe’s integrity and potentially result in failure. In auto industry, corrosion takes place at the location of scratches on the auto
paint, especially during freezing winter when salts are applied on road. Therefore, a quantitative and reliable tool for measuring the
influence of scratch testing on protective coatings and its corrosion resistance is in need, in order to select the most proper coating for the intended application.
