Microwear Testing

What Does Microwear Testing Mean?

Microwear testing refers to a collection of empirical surface and thermochemical examinations that are used to evaluate the degree of metal resistance to stress and strain forces that result in increased surface wear and tear.

Microwear testing is used to enhance the tribological and tribochemical properties of a metallic substance. These two properties predict metal corrosion and degradation in moving system environments, rather than metal structures that generally remain stationary after installation.

Corrosionpedia Explains Microwear Testing

The metal substance being evaluated is tested in a variety of process parameters and/or scenarios, and is performed by creating a characteristic layer on the metal's surface by the diffusion of nitrogen. This layer is then chemically modified to find a correlation with particular external influences that are unique to the metal's application.
