Special Issue Information

Dear Colleagues,

Acoustic emission (AE) is the emission of elastic stress waves resulting from deformation and fracture of materials. During tribological processes, AE waves are generated by the deformation and fractures of material surfaces, and considerable information can be obtained by measuring them.

AE techniques have tremendous potential in in situ measurements of tribological characteristics. Furthermore, it is expected to be widely used as a tool to diagnose and evaluate wear phenomena that are very complex and changeable. However, to apply AE techniques to identify and evaluate tribological phenomena and their characteristics, relationships between AE signals and tribological phenomena must be fully understood.

The Special Issue “Acoustic Emission Techniques in Wear Monitoring” published in Lubricants in January 2020, which attracted a lot of potential readers and authors, was a great success. Thus, we have decided to launch volume two, with the same aims of publishing the latest research focusing on wear monitoring by AE techniques for various tribo-materials and friction systems. We hope that this Special Issue will be utilized to make a breakthrough in in situ measurements and evaluations in the tribology field for the future. We are looking forward to receiving your submission.

The acoustic emission (AE) technique is an effective method for monitoring grinding wheels, and numerous studies have been published on applying an AE to monitor grinding wheels. However, there are few studies on the effect of the location of the AE sensor in stably acquiring the AE signals generated during deterioration in cylindrical grinding wheels. In this study, we propose a stable method for detecting the deterioration of a cubic boron nitride (cBN) grinding wheel during cylindrical grinding using AE. We compared the AE signals acquired during grinding from an AE sensor located on the hydrostatic bearing, which supports the grinding wheel shaft, with those from the tailstock spindle. Although positioning the AE sensor on the hydrostatic bearing was found to reduce the AE signal intensity, the AE signal variations were smaller at the same grinding position, and the effect of the grinding position was less than that for the tailstock spindle. Moreover, positioning an AE sensor on the hydrostatic bearing is considered to provide the characteristics of AE signals specifically focused on the changes in cBN on the grinding wheel surface allowing the surface roughness of the workpiece to be estimated during grinding.

During contact, deformation, and fracture of surface asperities between the friction surfaces of materials, acoustic emission (AE) waves are generated as the strain energy is released. By detecting the AE waves during friction using an AE sensor, the state of friction, wear, and lubrication between the friction surfaces can be measured and evaluated with high sensitivity. In this study, in order to establish a method for evaluating the writing performance of ballpoint pens by AE sensing, the measurement method was examined, and AE signal waveforms were analyzed. It was found that AE sensing can detect phenomena that do not appear as a change in frictional force during writing. In addition, frequency analysis of the AE signal waveforms revealed that differences in writing performance depending on the ink type of the ballpoint pen can be evaluated and interpreted.
