Indicators

In surface technology, indicators show the condition or progress of processes and properties on surfaces. These indicators can be visual, chemical, physical or technological and are used to provide important information about surface properties, process parameters or quality standards.

A common example of a surface indicator is color. Changes in color can indicate different processes or conditions, such as the formation of oxide layers, the absorption of dirt or the effects of environmental influences. The assessment of color changes can provide important information about the condition and quality of a surface. Chemical indicators are often used to indicate specific chemical reactions or processes on surfaces. For example, pH indicators can be used to determine the acidic or basic nature of a surface, while indicators of corrosion or oxidation can indicate the presence of corrosive or oxidizing conditions.

Physical indicators such as surface roughness, gloss or hardness can also provide important information about the properties of surfaces. These parameters can be measured and quantified with various measuring devices to evaluate the quality of surfaces or to control process parameters. Technological indicators in surface engineering include various types of monitoring and control systems that can monitor the progress of coating processes, the quality of coatings or compliance with quality standards. These include, for example, automated inspection systems, in-line measuring devices and quality assurance procedures.

Overall, indicators play a crucial role in surface technology by providing important information about surface conditions, process parameters and quality standards. By using different types of indicators, manufacturers can improve the quality and performance of surfaces, optimize processes and reduce production downtime.
