It is a well-known fact that desirable functional performance and service life of engineered parts can be obtained through a valid tribological process. To ensure the performance of the tribological process, each output response such as wear, material removal rate, surface finish, and the surface degradation process must be evaluated. Experiment design should be correlated with respect to the different input factors which have to be evaluated by following the standard procedures. In addition, surface characterisation techniques such as SEM, EDS, XRD, AFM, surface residual stress, and many more surface qualities decide the quality of the tribological process.

Machining has been recommended as a post-processing technique to meet industrial expectations, especially in the development of materials through advanced manufacturing processes such as additive manufacturing. Cold formation, electro spark sintering, and many more through cast processing are followed by secondary experimental processes to infer the tribological performance of the developed material. Most research is focused on sliding wear, erosive wear, abrasive wear, electro spark erosion, laser ablation, bio-erosion, etc.

This Special Issue intends to disseminate knowledge of advanced technologies in handling engineering materials related to wear, friction, and lubricant. This Issue will support researchers with technical articles on tribological behavior of advanced materials including metals and non-metals. Articles should provide contributions to microbial abrasion, sliding erosion, fretting corrosion, laser ablation, spark erosion, abrasion, and numerical simulations on erosion. Submitted articles are expected to cover experimental approaches, influence of input parameter, results of advanced surface characterisation studies, and significant justification on the mechanisms involved during the process. Original research and review articles are welcome.

Potential topics include but are not limited to the following:

• Bio-tribology in biomedical engineering
• Microbial machining of materials
• Micro- and nano-machining
• Lasers for surface engineering
