Weight function (Gaussian bell curve)

In surface technology, the Gaussian bell curve is used as a weight function in various contexts to evaluate certain parameters or influences. This mathematical function with its characteristic bell shape is used in the analysis of surface profiles, the evaluation of coating thicknesses and other qualitative or quantitative aspects.

In the characterization of surface profiles, the Gaussian bell curve plays a role in the evaluation of roughness. By integrating it as a weight function in corresponding analyses, it allows focusing on the areas of the profile that are close to the average roughness value. This helps to obtain a more accurate representation of the relevant characteristics of the surface.

In the quality control of coatings, the Gaussian bell curve is used to evaluate the distribution of the coating thickness. A uniform distribution close to the mean value of the bell curve indicates a homogeneous coating, while deviations from this value may indicate possible irregularities.

In surface technology, the smooth and symmetrical shape of the Gaussian bell curve makes it possible to prioritize or weight certain areas of the surface. This is particularly important in processes such as surface treatment or modification, where targeted control of parameters is required.

In addition, the Gaussian bell curve is used as a weighting function in filter applications to emphasize or attenuate certain frequency components in surface signals. This can help to emphasize relevant information or minimize interference.

Overall, the Gaussian bell curve plays an important role in surface engineering by enabling precise evaluation and analysis. Its versatility helps to increase the efficiency of processes and improve the quality of surface products.
